Description and Production procedure of Steel Pellet Pellets are small balls of iron ore used in steel production. They are one of the important sources of iron in the manufacture of steel. Pellet production is the basis of the steel production process. Steel pellets are made from iron ore powder with additives such as limestone, dolomite, olivine and binder bentonite. The addition of these additives and adhesives, in addition to preventing a large amount of gas produced by the evaporation of water from tending to rupture during the initial stage of heating, can also increase the strength of the particles before heating. The mixture is then mixed together in a mixer and fed into a disk or drum to produce coarse particles, usually about 9-16mm. Heat treatment of coarse particles, including drying, preheating, roasting, post-firing and cooling, is performed to obtain high metallurgical resistance and appropriate properties. The original particles are first fed into the hardening machine. Both the direct grate and the grate-kiln dried the particles in the dry zone, then heated the particles to about 800-900°C in the preheating zone, and then hardened at temperatures of about 1200 to 1350°C. The pellet is then cooled to a suitable temperature for transportation to the unloading equipment. Application of Steel Pellet Pellets are widely used in the iron and steel industry. Nothing can replace them. The structure of the iron ore pellets in the blast furnace allows air to flow between the pellets, which reduces the air resistance that passes up the charge layer during smelting. In addition, pellets provide advantages for end users, such as increased productivity of blast furnaces, increased opportunities for iron content in charging, and better environmental performance compared to sintering plants. As there is a global decline in high-grade block minerals, pellets are made from low-grade ores and are therefore relatively inexpensive and suitable for mass production. Their uniform particle size can ensure good permeability of blast furnace charge, and they have high voltage, good reducibility, high cold strength, and easy to transport and storage, not crack. Pellets contain fewer harmful elements, and they can also expand the source of raw materials for iron-making and smelting fuels.

Description of Steel Raw Material Steel is one kind of alloy, made of iron and carbon. The carbon content is usually less than two percent and for manganese, silicon, phosphorus, sulfur, and oxygen， the the content is even smaller. Steel is the most important engineering and building materials in the world. In the steelmaking process, the impurities, such as nitrogen, silicon, phosphorus, sulfur and excess carbon (which is the most important impurities) are removed from the source iron. To produce different grades of steel, some different alloying elements such as manganese, nickel, chromium, carbon, and vanadium need to add. The Steel-making Process There are two main business processes for steelmaking: blast furnace basic oxygen steelmaking (using blast furnace liquid pig iron and scrap as the main feedstock) and electric arc furnace (EAF) steelmaking, which uses scrap or direct reduced iron (DRI) as the main feedstock. Oxygen steelmaking provides fuel mainly through the exothermic properties of the reaction inside the vessel. Instead, in EAF steelmaking, electrical energy is used to melt solid waste and/or DRI materials. In recent years, with more chemical energy introduced into the process, the development of EAF steelmaking technology has approached that of oxygen steelmaking. The main difference between routes is the type of raw material they consume. For the BF-BOF route, it is mainly iron ore, coal, and recycled steel, while the EAF route uses recycled steel and electricity to produce steel. Depending on the configuration of the plant and the availability of recycled steel, other metallic iron sources such as direct reduced iron (DRI) or molten iron can also be used in the EAF route. Depending on the configuration of the plant and the availability of recycled steel, other metallic iron sources such as direct reduced iron (DRI) or molten iron can also be used in the EAF route. The principle of steel-making is to use oxygen or iron oxide to remove the excess carbon and other impurities contained in pig iron into gas or slag under high temperature. HUARO can provide different kinds of steel raw material, like iron ore, iron ore concentrate，HBI (Hot briquetted iron), DRI (Direct Reduced Iron) and steel pellets.

Description of Steel Bloom Usually, during hot rolling, the bloom is a semi-finished nearly square solid metal form between the ingot and the billet. The cross-section of the slab bloom is usually greater than 225 square centimeters and about 8 to 12 meters long. In the rolling mill, it is broken down into finished products such as bars, beams and sheet piles. In earlier mills, ingots were made from cast ingots (called "nodular iron"), but in modern mills they are made by continuous casting. Production Procedure of Steel Bloom The ingots, still hot sometimes, reach the tram plate mill and billet mill and are placed upright in a soaking pit under the floor by a special crane. Steel bloom are rectangular gas chambers about 5 meters deep, in which four to eight ingots are simultaneously heated to about 1,250°C (2,300°F). The soaking pit is highly computerized and can be used for scheduling, firing rate, heating time (lasting 8 to 18 hours) and rolling programs. After heating, the conveyor carries the hot ingot to a two-high reversing mill, which passes, again and again, turning the roll and roll table over each time the ingot passes. Since each pass reduces the bloom by only about 50mm, 21 passes may be required, including several edges pass, and the bloom stands upright on its edge to obtain a slab bloom billet of 150mm*150mm. We have steel slab,please feel free to contact us. https://www.huaro-shanghai.com/products/ste , el-bloom.html

General Introduction of Steel Billet Prime steel billets are the second stage product in steel production. They belong to hot rolling and directly made and formed in the process of steel smelting, belonging to the category of casting semi-finished products. Their final products involve deformed steel rods, wires, and other steel products. As one of the professional steel billets manufacturers, HUARO offers high-quality steel billets for sale. Steel Billets Production Process The steel billets production process consists of three steps. First, prepare scrap iron or sponge iron (DRI). Secondly, scrap iron or sponge iron (DRI) is melted in an electric arc furnace (EAF) and the necessary elements are added to enhance the properties and quality of the steel billets to meet standard quality and customer requirements. Electric arc furnace technology converts electrical energy into heat to melt steel. Compared with most other metal melting methods, the advantages of the arc are clean, energy-saving and controllable melting processes. Finally, the steel is cast into billets. Application of Steel Billets The company's customers use steel billets to make round steel, shaped steel, and coils. These long products are mainly used in small and medium-sized construction projects, such as residential and commercial units, and other general construction projects, including machine tools, auto parts, and large construction projects requiring steel billets for reinforced concrete. High strength and durability, can be used in Bridges, DAMS, highways, and structures that can withstand high compression forces as well as high-rise buildings. Specification for Steel Billets Steel Billets conform to various types of steel and accordingly include JIS DIN ASTM EN and GB standards. The normal thickness is 130 * 130mm and 150 * 150mm, and the length is usually 6m-12m. Both ends will be gas cut and at the end of each blank, the mold number will be stamped or painted.
