Ferro Silicon
Usage
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 diffusedeoxidation.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.
Application
Used as deoxidants and desulfurizing agents, and could purity the molten steel, etc. The size includes:0-3mm, 3-25mm,10-50mm, etc.

Specification
- Q:What's the maximum temperature that the refractory ceramic fiber cloth can endure?
- It depends on the composition of the ceramic material. If its composition is alumina and it is used by civilians, its normal use temperature is 1200℃; if its composition is alumina but it is for millitary use, it can endure the highest temperature of 2200℃.
- Q:How many grades of fire?rating are there for interior decoration materials?
- It can be divided into structural material and base?material based on materials. It can also be divided into flammable, flame retardant and non-combustible materials based on fireproof types. There is no fire?rating for materials. But lengths of time of flammability limits are different.
- Q:What material is used to make furnace pipe of refractory bricks?
- Refractory bricks furnace pipe material is generally divided into two types, namely, shapeless refractory material and shaped refractory. Shapeless refractory material, also known as castable refractory, is hybrid powder material made up of many kinds of aggregate or aggregate and a kind of or many kinds of binders. It must cooperate and evenly stir with a kind or many kinds of liquids during use and has strong mobility. Shaped refractory material usually refers to refractory brick whose shape has standard rules. It can also be proceeded temporarily during cutting according to requirement.
- Q:Is refractory material harmful to human body?
- Part is harmful to human body, mainly refractory raw material, silica powder inhalation can cause lung tuberculosis, siliceous fiber on the human body does have great harm, in fact, like other inorganic fiber in the inhalation of the trachea or lung after the same harm to human
- Q:what should be paid sttention when buying the refractory?
- First, look at the appearance of the product, it will be better if the surface of product is smooth, if there are the injuries and damages which may influence the use, do not use it. Second, the main characteristics of insulation material is flame resistance, reduce the loss of fire occurred at the time of purchase combustion performance testing products, non-combustible stone wool products are the best. Third, refractory insulation with good hygroscopicity is also very important, it can keep your room drying for a long time , played the role of moisture-proof, and more capillary, the hygroscopicity is better.
- Q:What is the biggest difference between refractory bricks and clay refractory bricks? Where can I find information on the refractory bricks?
- You can look up knowledge manual of refractory material to find phosphatic material, etc. Xinjiang refractory bricks, castable refractory, refractory material, silicious, corundum and alumina-magnesia: High alumina and clay refractory bricks can be divided into
- Q:How to divide the fire resistant level of construction thermal insulation materials?
- 1, Combustion performance of the national standard building materials are divided into the following levels: Class A: incombustible building material: Material that almost never burn. Class B1: nonflammable building material: Nonflammable materials have good effect of flame resistance. In case of fire it in the air or at high temperature it is difficult to catch fire and spread, and when the fire source is removed, the combustion can stop immediately. Class B2: combustible?building?material: Combustible materials have good effect of flame resistance. In case of open fire in the air or at high temperature, it will immediately burst into flames and spread the fire quickly, such as wooden column, timber roof truss, wooden stairs, etc. Class B3: flammable building material: No flame-retardant effect, highly flammable, high risk of fire. 2, According to fire?rating, external wall thermal insulation materials can be divided into 1) thermal insulation material with class A combustion performance. Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite,etc. 2) thermal insulation material with class B1 combustion performance: Extruded polystyrene board (XPS) after special treatment /polyurethane (PU) after special treatment , phenolic aldehyde, gelatine powder polyphenyl granule, etc. 3) thermal insulation material with class B2 combustion performance: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
- Q:How long is the fire endurance of Grade A fire resisting shutter
- The fire endurance of Grade A fire resisting shutter is not lower than 1.20h. Use fire resisting shutter as fire?compartment separation in places where it is difficult to set firewall. When fire resisting shutter whose unexposed surface temperature rise is used as judging condition of fire endurance is used, its fire endurance should not be lower than 3h. When fire resisting shutter whose unexposed surface temperature rise is used as judging condition of fire endurance is not used, individual protection of ?closed automatic water spray system shoule be set at two sides of the shutters and duration of water spray system should not be less than 3.0h.
