Fused magnesia (FM) is a type of refractory material that is produced by the electric arc melting of caustic calcined magnesia, deadburned magnesia or raw magnesite in furnaces at temperatures in excess of 2750°C. It has a high melting point, excellent thermal shock resistance, and good chemical stability, making it a popular choice for use in a variety of industrial applications such as steelmaking, cement manufacturing, and glass production.  Fused magnesia (FM) Application: - High performance MgO-C refractory bricks for steel industry, - Fired refractory bricks for cement and glass industry, - Heating elements industry Mingshi Fused Magnesia Production Process: Magnesite (magnesium carbonate MgCO3) is converted into magnesia by the application of heat which drives off carbon dioxide (CO2), thereby converting the carbonate to the oxide of magnesium (MgO). Fused magnesia is a high-purity material used in the production of refractory materials, ceramics, and other industrial applications. The production of fused magnesia involves several steps. Raw Material Preparation: The raw material used in the production of fused magnesia is magnesite, a natural mineral. The magnesite is first crushed into small pieces and then calcined at high temperatures to remove impurities and water. Fusion: The calcined magnesite is then mixed with coke and other additives and fed into an electric arc furnace. The furnace is heated to a temperature of around 3,000 degrees Celsius, causing the magnesite to fuse into a molten state. Cooling and Solidification: The molten magnesia is then cooled and solidified by pouring it into molds or by spraying it with water. This process can take several days or even weeks, depending on the size and shape of the desired product.

85%-92% Dead burned magnesiais mainly made of natural magnesite ore with 46% content, which is calcined by high temperature kiln at about 1400℃-1800℃. Application: Dead burned magnesia is mainly used as raw material for making magnesia bricks and producing amorphous refractory materials. The finished products are used in steel making, electric furnace bottom and ramming furnace. The main varieties of dead burned magnesia have 85%-92% content, these varieties are mainly selected 46.5% to magnesite, sintered kiln calcination heating to 1400-1800 ℃ Mg(CO3) completely decomposed, generating magnesite, become hard reddish-brown dead burned magnesium, it has a high refractorability. Dead burned magnesia is mainly used for magnesia brick, steelmaking, electric furnace bottom and ramming furnace lining.

The stainless steel induction heating solid solution bright annealing furnace is widely used in a stainless steel welded pipe production line, In the manufacturing process of the stainless steel pipe, the diameter of the pipe is Φ6 and Φ273mm, which is suitable for stainless steel SUS304, 316, 316L, etc. The online running speed is adjustable from 0 to 10M/min, the heating temperature is set according to the material of the solution treatment, and the advanced infrared temperature measuring automatic detection system and the synchronous solution refrigeration system are equipped with the advantages of simple operation, multi-function, multi-protection, multi-display, and integrated self-contained water cooling system. need not be equipped with external water cooling device. The steel pipe is heated by all-solid-state IGBT induction heating power supply, which has the characteristics of small occupied area, light weight, low working voltage, high safety factor, low high-frequency radiation, low noise, low failure rate, low maintenance difficulty, and the like. The control system is controlled by PLC imported from Germany. Large-screen display made in Taiwan can be used to visually understand the operation status and fault condition of the equipment. The whole machine is equipped with various protection measures to greatly improve the stability and reliability of the equipment and complete the interlocking control and protection functions with the production line. The bright heat treatment process avoids the environmental pollution caused by the traditional pickling treatment process, and aims at eliminating the structural defects of stainless steel, reducing the hardness, improving the performance of steel and restoring the plastic deformation capability of the steel to meet the processing requirements. The induction heating power supply is used to heat the stainless steel tube to the temperature above its phase change temperature (austenitic stainless steel generally does not exceed 1100 degrees centigrade) and then cool down after a certain time. Generally for protective atmosphere annealing, the purpose is to avoid oxidation caused by the surface of the regeneration of iron oxide scale, so commonly known as bright annealing. The bright continuous heat treatment furnace mainly consists of a heating part and a cooling part. In order to meet the requirements of welding different pipes, an independent support frame device is designed, on which heating and quenching systems are installed. The support frame can adjust the height of the center line of the bright heat treatment device. The quenching chamber connected to the sealing bush of the heating coil is completely closed, and the water is cooled on the outer surface, while inside the tube, a conductive medium with high heat conductivity rapidly transfers heat from the stainless steel tube to the outer water cooling chamber surface. The whole quenching process is carried out under the control of the protective atmosphere to ensure that the brightness treatment can be continued before the outlet temperature. At the same time, the equipment adopts intelligent ignition system to monitor the flame state at any time. Because the furnace body adopts front and rear sealing and the air path is reasonable, the bright reaction is quick, the number of black pipes is reduced, and the consumption of protective gas is greatly saved for users. A heating sensor designed to increase heating efficiency includes an atmosphere sealing bush containing a controllable protective gas for preventing contamination from the external environment. The direct water quenching device plays a very important role in keeping the consistency of product size. and the length of quenching is kept to a very small extent.

The application of stainless steel profiles in engineering construction is based on the good corrosion resistance of stainless steel, so that the structural members can permanently maintain the integrity of the engineering design. Chromium-containing stainless steel also combines mechanical strength and high elongation, making it easy to process and manufacture parts that can meet the needs of architects and structural designers. After the first successful practical application, the stainless steel profiles have the standard specifications of stainless steel Angle, flat and square steel. Stainless steel profiles are stainless steel materials with different cross- section shapes made by hot melt extrusion of stainless steel rods. The production process of stainless steel profiles mainly includes three processes: casting, extrusion and coloring. Among them, coloring mainly includes: oxidation, electrophoretic coating, fluorocarbon spraying, powder spraying, wood grain transfer printing and other processes. Stainless steel Angle steel: Gauge ∠10 mmX 10mm-∠150mmX150mm. Stainless steel flat steel, stainless steel square steel: specification 10mmX10mm-7 50mmX750mm.

1. Reduced corrosion resistance due to damage or contamination. Corrosion may occur where the film has been damaged, and other forms of contamination are present that prevent the natural re-formation of the passivated film. All the beneficial properties of stainless steel can be destroyed during processing, such as heat treatment or machining, such as welding, cutting, sawing, drilling and bending. As a result of these treatments, the oxide protective film on the stainless steel surface is usually damaged or contaminated, making it impossible to achieve spontaneous and complete passivation. As a result, localized corrosion may occur, even under conditions where corrosion is relatively weak. When used, it can result in an unsatisfactory end product, or even worse, the failure of critical systems. A: Welding causes accelerated oxidation on the inside, outside and near the weld. Oxidation is visible because there are areas of discoloration, and the color is related to the thickness of the oxide layer. Compared with the oxide layer on the stainless steel before welding, the oxide layer in the discolored zone is relatively thick, and the composition changes (containing less chromium), which reduces the local corrosion resistance. For the inside of the tube, oxidation and discoloration can be minimized by using proper backwashing methods. After welding, post-welding treatments such as pickling and grinding are usually required to remove oxides (color) and restore corrosion resistance. Color charts are often used to determine whether a weld needs pickling based on color grade. However, this decision is subjective, and in principle each color indicates the presence of oxidation and the affected oxide layer, thus reducing corrosion resistance. B: Mechanical treatment usually uses mechanical or non-mechanical contaminated surfaces. Organic pollutants can be caused by lubricating oil. Contact with tools can lead to inorganic contaminants such as foreign iron particles. Plaque is often caused by surface contamination of all kinds. In addition, foreign iron particles may cause galvanic corrosion. Pitting and galvanic corrosion are local forms of corrosion that initially require water treatment. Therefore, surface contamination usually reduces the corrosion resistance of stainless steel. 2. Surface treatment. In order to prepare the surface, remove discoloration and restore corrosion resistance, there are many post-treatments and methods. Here again we should distinguish between chemical and mechanical methods. Chemical methods are: pickling (soaking, with pickling paste or pickling spray), auxiliary passivation (after pickling) and electrolytic polishing. Mechanical methods are: sandblasting, glass or ceramic pellet shot blasting, painting, polishing. While all methods produce welded joints, no mechanical post-treatment will provide corrosion properties suitable for harsh applications. Use chemical methods to remove oxides and other contaminants from surfaces, while using mechanical methods to potentially remove contaminants from previously removed, polished, or erased materials. All kinds of pollution, especially foreign iron particles, can be a source of corrosion, especially in humid environments. Therefore, mechanically cleaned surfaces are best cleaned regularly under dry conditions. After pickling, it is important to properly rinse with water to remove all contaminants and pickling residues. The final rinsing should be done with softened water to avoid calcium stains and contaminants embedded in the growing oxide layer, which is necessary to build the passivation layer. In addition, due to the use of chemical methods (pickling and electrolytic polishing) to improve corrosion resistance, iron dissolves faster in pickling solutions and electrolytes than other metals. According to this, the surface is enriched with chromium and becomes more durable. Therefore, chemical methods of pickling and electropolishing are the only post-treatment methods that can restore the corrosion resistance of stainless steel in the weld and other surface damage that occurs before welding. This is actually independent of the type of stainless steel, there is no difference between the effect of pickling by soaking in the tank and using pickling paste or spray.
