Silicon Carbide
Silicon carbide, dissolved in a basic oxygen furnace used for making steel, acts as a fuel. The additional energy liberated allows the furnace to process more scrap with the same charge of hot metal. It can also be used to raise tap temperatures and adjust the carbon and silicon content. Silicon carbide is cheaper than a combination of ferrosilicon and carbon, produces cleaner steel and less emissions due to low levels of trace elements, has a low gas content, and does not lower the temperature of steel.

- Q: what's the classification of fireproof and thermal inuslation matertial?
- 1. thermal insulation material with A class combustion performance. Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite (2) thermal insulation material with B class combustion performance: extruded polystyrene board after special processing (XPS)/ polyurethane after special processing (PU) , phenolic aldehyde, gelatine powder polyphenyl granule. 3,thermal insulation material with B2 class combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane (PU), polyethylene (PE),etc. sea capacity module and vitrified micro bead(cooperate with the innovator of vitrified micro bead, Liu Weihua) fireproofing issues have been completely solved.
- Q: Which industry does the metallurgy and thermal insulating and refractory material belong to?
- It belongs to the refractory industry, which has its own trade association.
- Q: who knows the requirements of refractory for forge furnace?
- Requirements are as follows: 1, it should have enough refractoriness and softening point under a fixed load. Because under the effect of electric arc, inner surface temperature in different parts of furnace lining can reach 1500 ~ 1800 ℃. 2, it should have strong slag resistance. Because slag and smoke at high temperature penetrate through furnace lining to its internal lining, causing the melting of refractory, organization stratification, and even peeling?off. 3, it should have good thermal shock resistance. Because in the process of steelmaking, openning the oven door and lifting the furnace lid will make temperature of refractories in the furnace lining change rapidly, it might happen peeling?off and cracking, causing the premature failure of furnace lining. 4, it should have sufficient strength, because the furnace lining will be shocked when being loaded, vibrated when being tilted, scoured by metals,molten slag and air flow when boiling. 5, smaller thermal conductivity, lower electrical conductivity. Commonly used refractories for electric furnace include magnesia bricks, dolomite brick, high alumina refractory brick, siliceous refractory brick and magnesite ramming material,etc. owing to the different work environment of each part of the furnace,refractory used by each part is also different.
- Q: What is the role of the vermiculite fireproof material?
- Apart from inflaming retarding, the materials covered with vermiculite has a lot of advantages including anti rust, waterproof, anticorrosive, wear-resisting, heat-resisting and the coating is armed with toughness, colorability, adhesiveness, fast-drying and luster.
- Q: What is the appropiate thickness if fire resistant time for ultra thin steel structure coating is 2.5 hours?
- According to the "code for fire protection design of tall buildings", the fire resistance time of the component is at the first level: 3 hours, beam: 2 hours, floor: 1.5 hours;if fire resistance level is level the requirement for time of fire resistance component is the column: 2.5 hours, beam: 1.5 hours, floor: 1 hours. For fire resistant coating, fire resistance time for ultra-thin fire retardant coating is shorter than 1.5 hours. If the time exceeds 1.5 hours, thick fire resistive coating should be used. Steel structure can adopt surrounding concrete or brick, fireproof coating, fireproof board coating and composite structure for its fire resisitance. Fire resisitance board can be divided into thick fire protection plate and thin plate, the thickness of the plate thickness of the fire is between 20 ~ 50mm, mainly includes calcium silicate fireproof board and expansion boring stone fire board, the main varieties are KB board, CF; thin fireproof plate is between 6 ~ 15mm thick, the main varieties include enforced short fiber cement plate, ordinary enforced fiber silicate calcium board and glass cloth reinforced inorganic board. As is known to all, steel structure usually will lose bearing capacity usually in 450 to 650 degree, leading to deformation, steel column and beam bending, and be no longer usable at last. Generally fire resistant limit of unprotected steel stucture is about 15 minutes. 1.5 hours;if fire resistance level is level the requirement for time of fire resistance component is the column: 2.5 hours, beam: 1.5 hours, floor: 1 hours. Steel structure an use surrounding concrete (or masonry), fire retardant coating, fire retardant plate and compround structure to achieve the required refractory limit. Hope my answer will help you.
- Q: Refractories for iron-making blast furnace?
- This question is too professional - as far as I know, there are blast furnace noumenon bricklaying - trough slag runner fire-resistant model ~ main channel carbon rod ~ ramming mixes ~ ~ I do not know the specific details.
- Q: What refractories can withstand high temperature above 2100 degrees?
- Usually a dryer will not have such a high temperature. I do not know what you would use it for. Refractory cement coupled with quartz sand can work for 4 to 5 hours. So you can try cement coupled with corundum or superfine bauxite for better effect.
- Q: Fefractory of aluminium oxide.
- It can be refined into castable refractory and refractory bricks, according to temperature rating. There are shaped refractory material and shapeless refractory material, and ceramic fiber. So it must be specific. There is a large range of refractory, which basically contains the aluminium oxide.
- Q: what is steel fire door made of ?
- 1. fire resistance steel door has steel made door frames, door leaf framework and door panels. if the door leaf is filled with nontoxic fire insulation material, added with fireproof hardware accessories, which consists of a door that is fire resistance. This is a steel door.
- Q: What needs to be paid attention to in the construction of high- temperature refractory mortar?
- 1. During the use of high- temperature refractory mortar, the minimum mortar joint should be 0.5mm and general mortar joint should be 3-5mm, which can solve the processing and fine grinding of refractory brick on the brick grinder. Besides, it is conducive to the health of workers, and can reduce the masonry effort, ensure the quality and speed up the construction progress. 2. When making urgent repair on the stove, if the joint is much too large, 2-3mm refractory pieces can be appropriately added into the high- temperature refractory mortar, and stirred to fill the joint so as to shorten the repair time and ensure normal production. 3. High- temperature refractory mortar can be painted inside various furnace body, and it should be guaranteed that the surface of the furnace body has no dust or debris before painting.
