Product name: Kyanite powder Form: powder Specification:80 mesh- 325 mesh Colors: grey and white CAS No.:1302-76-7 PRODUCT DESCRIPTION About Kyanite powder: Kyanite is a kind of natural refractory mineral with high refractoriness and large volume expansion at high temperature. There are parallel stripes on the crystal plane. Color is light blue or cyan, bright gray and so on. It belongs to high aluminum minerals. Its chemical corrosion resistance is strong, thermal shock mechanical strength, heat expansion irreversible. It is the main raw material for the production of amorphous materials, electric furnace top brick, phosphate non-fired brick, mullite brick, low creep brick. Process characteristics of kyanite powder: 1. Thermal expansibility: The kyanite mineral is converted into a mixture of mullite and kyanite during heating. During this transformation process, the mineral expands with volume and forms a good quartzite needle-like network with volume expansion rate of 16-18%. 2. Stability: the stability of kyanite refractories is 1.5 times higher than that of clay refractories. The loss of kyanite refractory brick is 43% lower than that of clay brick, and its life span is 150-200 furnaces longer than that of clay brick. 3. High refractoriness: general clay refractory refractoriness is 1670-1770 deG C, and the refractory of kyanite is usually greater than 1790 DEG C, the highest is greater than 1850 DEG C. 4. Irreversibility: calcination of kyanite into mullite is an irreversible transformation. It is stable below the temperature of 1810℃. Therefore, mullite refractories have the characteristics of stable volume at high temperature, low expansion rate, strong chemical corrosion resistance, high mechanical strength and strong thermal impact resistance.   Kyanite powder Usage: Because of the characteristics of kyanite mineral, it is used to manufacture excellent high-grade refractory materials, refractory mortar, cement, casting resistant products, plastic ramming mixture, technical ceramics, spark plugs for automobile engines, insulators, ball mill balls, test vessels, earthquake resistant articles, etc. (1) high temperature by using kyanite a permanent expansion of monolithic refractories (added directly, such as pouring material, high temperature expansion agent can be made of plastic, rubber) as long as add 5% ~ 15% can improve refractoriness under load, crushing strength of the product improvement after burning linear change index, elimination of monolithic refractories in the high temperature and the cooling process of contraction crack, Spalling and other weaknesses affecting service life # thus prolonging the lining life. (2) Aluminate fibers produced from high alumina minerals of kyanite can be used to make parts for automobiles, spaceships and radar. (3) mullite produced by calcination of kyanite can be used for high temperature furnace to prolong the furnace life of 5 ~ 6 years and save energy. (4) adding 5% ~ 15% kyanite in high alumina cement can be made into kyanite cement, fire resistance temperature up to 1650℃, can be used in military buildings. Kyanite minerals are mainly used in the production of refractory materials, alumina, silicon aluminum alloy and metal fibers. Contact Us - Hebei Yayang Spodumene Co., Ltd.

Product name: Volcanic stone Form: stone Colors: red PRODUCT DESCRIPTION About Volcanic stone: Volcanic stone (volcanic rock or pumice) is a dense porous vitreous lava formed by the rapid expansion of internal gases after the sudden cooling of magma in the process of volcanic eruption. The pore volume accounts for more than 50% of the rock volume. Because of the porosity, light weight, can float on the water is called pumice. It is characterized by high strength, heat preservation, heat insulation, sound absorption, fire prevention, acid and alkali resistance, corrosion resistance, and no pollution, no radioactive etc. Volcanic stone Usage: Aquatic area: living water, stable water quality, lure, adsorption, play props, promote metabolism, optimize growth, nitrifying bacteria culture, aquatic grass growth matrix material. Plant planting field: because the small particle volcanic stone (1~6 mm) is loose and porous, rich in minerals, resistant to insect pests, and cheap, it is mostly used for soil or pavement of succulent plants to increase soil permeability, prevent root rot of succulent plants and prevent insect pests. Some plants that need to increase soil permeability can also add small particles of volcanic stone in the soil to prevent soil water from causing adverse effects on plants.

(1) Ferrosilicon is an indispensable deoxidizer in the steelmaking industry. In steelmaking, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used in steelmaking as an alloying agent. (2) Used as an inoculant and a nodularizer in the cast iron industry. In the production of ductile iron, 75 ferrosilicon is an important inoculant (helping to precipitate graphite) and nodularizing agent. (3) Used as a reducing agent in the production of ferroalloys. Not only the chemical affinity between silicon and oxygen is very high, but also the carbon content of high silicon ferrosilicon is very low. Therefore, high-silicon ferrosilicon (or siliceous alloy) is a commonly used reducing agent in the production of low-carbon ferroalloys in the ferroalloy industry. (4) 75 ferrosilicon is often used in the high-temperature smelting process of metal magnesium in the Pidgeon process of magnesium smelting. The magnesium in CaO.MgO is replaced, and about 1.2 tons of ferrosilicon are consumed for each ton of metal magnesium produced. Magnesium metal production plays a big role

Special-Shaped Lead Brick Heavy Industry Lead-Antimony Alloy Product Description An antimony-containing lead alloy used in the manufacture of grids and conductive parts for lead-acid batteries. Compared with pure lead, it has a lower melting point, good fluidity in molten state, easy casting and molding, and high hardness after solidification; the disadvantage is that the gas evolution overpotential of the grid is low. In order to reduce the precipitation of gas during charging of the battery, reduce self-discharge and improve corrosion resistance, the antimony content has been gradually reduced from the traditional 5% to 7% to about 2% or even lower. At the same time, a small amount of other components such as tin, arsenic, sulfur, selenium and copper are selectively added to improve the physical and chemical properties of the alloy. Welding temperature 287℃-294℃. According to the welding temperature, the composition ratio is also different. Physical: Lead (Pb99) : melting point 327℃, density 11.34g/cm3. Tin (Sn99.95) : melting point 232℃, density 7.29g/cm3. Antimony: melting point 630℃, density 6.62 g /cm3.

Sheet Metal Forming Roll Forming Galvanized Roofing Processing Service 1 What are the special terms for the sheet metal industry? The forming ability of sheet metal is improved in the process of progressive forming. From the forming limit diagram, it can be seen that the forming limit can be expressed by Max minε+ε. Therefore, the sheet metal can have a greater amount of deformation in progressive forming. The disadvantage of progressive forming is mainly that the forming efficiency is low and the relative time needed to form a single part is relatively long. Therefore, how to improve the forming efficiency is also a very important premise of whether it can be widely used. 2 Technical Parameters Product name Sheet Metal Forming Roll Forming Galvanized Roofing Processing Service Item Bending Stainless Steel Sheet Stainless Steel Tube Bending Company Sheet Metal Fabrication Sheet Metal Forming Material carbon steel, Stainless Steel, brass, copper, aluminium Surface treatment powder coating etc, brushing, degrease Process Stamping, deep drawing, partial forming Application Industrial, building material, 3 Product Details Use: Electronic locker Function: This is a part used in the electronic locker and we can easily find out that it is a case of the loker with ABS Technology: plastic injection, burr remove
