Product Description
Ferro silicon is widely used in the steel making,iron casting ,low-carbon ferroalloy producing:
1 In the steel making field,Ferro silicon is used as deoxidizer and alloying agent to precipit and diffuse deoxidation.Adding a certain amount silicon of fe-si to the steel can obviously improve the strength ,hardness ,elasticity and permeability of steel.
2 In the iron casting,it is used as ball mile agent and alloying agent especially in the nodular iron casting, Adding ferrosilicon to cast iron ,it can prevent the formation of carbide and promote the precipitation of graphite and the nodulizing.then the mechanical capacity can be the same of steel's.
3 High-silicon ferrosilicon can be used for the production of the low-carbon reductant in ferro alloy industry.
4 In addition ,ferro silicon powder can be used as a suspended phase in the mineral processing industry and coatings for welding electrodes in the electrode manufactruing.

- Q: what is best for making refractory insulation for Blast furnace, hot stove.
- High dimensional insulating blanket.
- Q: Is fireclay poisonous?
- Refractory materials are typically oxides, alumina, magnesium oxide and aluminate cement and etc, which are non-toxic.
- Q: I wanna ask you, which level is b1 fireproof and thermal inuslation matertial ??
- which level is b1 fireproof and thermal inuslation matertial: I soppose you mean rubber and plastic! Only rubber and plastic has b1b2 level. Level b1 is the fireproofing level b1, because the rubber and plastic does not belong to the fireproofing material. It only has fire?retardant. The wholesale of all kinds of thermal insulation material and construction needs to look at the name.
- Q: Which kind of furnace hearth refractory is better?
- hearth selected material] hearth material must be durable, high temperature resistant, general selecting masnory made of refractory cement, silicon carbide refractory products, mullite or multicrystal mullite (which is the general term of minerals composed of a series of aluminum silicate, mullite is only stable binary compound in the Al2O3-SiO2 system) etc.. [hearth] is a three-dimensional space surrounded by furnace walls for combustion of the fuel. The funtion of hearth is to ensure the fuel to burn as far as possible, and to cool the gas temperature of the hearth exit to the allowed temperature of convection heating surface safe operation . Therefore, the hearth should have sufficient space and adequate heating surface. In addition, there should be reasonable shape and size in order to fit the burner and the organize aerodynamic field inside the furnace to prevent the flame from adherence, dashing walls and have high fullness and eve wall thermal load.
- Q: What kind of material is refractory bauxite?
- In China it is generally believed: "Bauxite ore refers to the mineral with a fairly high aluminum content (over 40%), and aluminum silicon ratio is greater than 2.5 (A / S≥2.5). Minerals with an aluminum content less than this value is called clay ore or allite shale or aluminious rock. " In China, it has been explored that monohydrate bauxite ore accounts for about 98% of the total reserves of bauxite.
- Q: What are the types of refractory sealant?
- Hello: I'm glad to help answer your questions! Measure fireproof material is high polymer plastic seal material which is used for seal. It has a dual performance of both sealing and fireproofing. It can be applied for fire protection construction of metal pipes, thermal insulated pipes and construction juncture. Fire-resisting sealant has an expansion rate of greater than 20% and it is resistant to nuclear radiation, LOCA, detergents, and it has radioactive decontamination performance. It has a durability of more than 40 years; It is free of halogen, sulfur and other toxic matters, watertight, anti-smoke, corrosion free, safe and environmental-friendly. It gives off no toxic smoke and is efficient in inflamming retardancy which is easy to construct. I hope my answer will be helpful to you.
- Q: What are the disadvantages of the refractory industry?
- The rapid development of continuous casting technology allows Hua Heng refractories to be improved in variety and quality. The development of refractory for continuous casting has a significant impact on the production of continuous casting and quality of continuous casting billet. Constructing and putting Baosteel into action has greatly pushed the improvement of the refractory technology. Continuous casting refractory is an important part of the continuous casting machine. In addition to the general characteristics of refractories, it is also required functions that can purify molten steel, improve the quality of steel, stabilize temperature and composition of the molten steel, control and regulate the molten steel flow. Therefore, it is known as functional refractories. Continuous casting Refractories include: (1) ladle refractory - ladle lining, permanent lining and ventilation components; (2) tundish refractories - permanent lining, coating, insulating plates, clad etc; (3 ) functional refractories - long nozzle for non-oxidizing casting, submerged nozzle, monolithic stopper, sliding gate; (4) ceramic purifier for purifying molten , slag dam, alkaline paint and horizontal separating ring and gate board for continuous casting.
- Q: What kinds of refractory materials that uses a-Al2o3 powder? What are the purpose of it?
- 04La-Al2O3 powder is a alumina powder whose raw material is industrial aluminum oxide which has been calcined at high temperature. It is a good polishes for ceramics and jade, meanwhile, it is also an important raw material for high-end refractory materials. The technical indicators parameters A1023 mark A1535 chemical composition AL2O3≥ 99.92 3%, ≥ 3.10FE203≤ 0.799 Refractory calcined alumina powder (a-Al2O3) 1.2 true density (g & # 47, by fully ground powder made of different fineness .O.10 0.07 0.04NA2O≤ 0.93a-Al2O3 (%) ≥ 95 95 primary crystallization average grain (um) 2 ~ 3 3 ~ 5 average particle size (um) 40 ~ 602.6SIO2≤ 0.1 0.15B2O3≤ - 0, glass, engineering ceramics typical use electronic ceramic insulating ceramic refractory ceramic wear 3
- Q: what's the materials of fireproof?housing?
- what's the materials of fireproof?housing? what's the fire?rating? how much is it? What are the key installation points?
- Q: What are the main materials in concrete fireproofing material?
- fireproofing materials mainly consist of class A incombustible?material and class B1 nonflammable material. Class A incombustible?material: Granite, marble, terrazzo, cement products, concrete products, gypsum board, lime products, clay products, glass, tiles, mosaics, steel, aluminum, copper alloy; class B1 nonflammable material: Ceiling materials, dry wall, fibrous plaster.
