In the same condition, using manganese or silicon to deoxidize separately, the burn out rate are 46% and 37%, but it is only 29% if using manganese alloy to deoxidize. So, it is used widely to smelting steel and its output increases faster than ferroalloy's, so has become an indispensable composite deoxidizing and alloy additives in steel industry. The silicon-manganese which contains carbon below 1.9% still is used to produce medium/low-carbon ferromanganese and semi-finished products of electro silicothermic process manganese metal.
- Q: What is the upper temperature limit for refractory materials?
- The key depends on what refractories you use
- Q: how to use boiler fireclay
- Boiler refractory, diluted with water to touch the places where needed, can be used after high temperature baking.
- Q: Which industry does refractory belong to? Does it belong to construction industry?
- It belongs to material, and after all, more than 60% refractories are used in metallurgical industry. If you insist on classifying it, it belongs to supporting industry of metallurgical industry. Refractory industry itself is independent.
- Q: Concrete composition and function of magnesia bond used in refractory
- The first answer is 2 points, and the answer is accepted. You get a reward and 20 bonus points. Magnesia, magnesia brick, magnesia brick, magnesia brick, magnesia calcium brick, magnesia carbon brick
- Q: Who can tell me about the foundry refractory materials?
- Such as: neutral, alkalic, acidic refractories. Of course, the raw materials of different materials are not the same. Such as: the magnesia-carbon bricks, basic refractory materials: magnesite(electric?smelting, high-purity)+ crystalline flake graphite+ phenolic resin+ additive (aluminate or silicon powder or silicon carbide powder or high-temperature pitch) and so on.
- Q: What is the use of refractory?
- Refractories mainly provide stable working environment for high temperature operation , such as metallurgical industry (steel ladle, hot-metal bottle, torpedo car and most places directly in contact with molten steel and iron), chemical industry (coke oven cokeing, dry quenching engineering) and building materials industry (lime kiln and glass kiln)
- Q: What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?
- I am not quite clear. But you should take two aspects into consideration, namely, no pollution and strong durability.
- Q: What's the material of electrical fire prevention board?
- Industrial electrical fire prevention board is mainly aimed at fire protection and thermal insulation. Iron plate is electrically conductive with good thermal conductivity, which will cause the result that the equipment is not insulated and suffers larger superheating surface! ! ! !
- Q: Which one is the best refractory material?
- 1, Acid refractory usually refers to the refractory material whose content of SiO2 is more than 93% , and is characterized by erosion resistance to acid slag under high temperature , but it is easy to react with alkaline slag. Commonly used acid refractory materials include silica bricks and clay bricks. 2, Alkaline refractory material is a kind of refractory material whose components are magnesium Oxide or the mixture of magnesium oxide and calcium oxide. 3, Aluminosilicate refractory refractory material refers to refractory material which makes SiO2-Al2O3 as the main component. According to the content of Al2O3, it can be divided into semi silica (Al2O3 15~30%), clay (Al2O3 30~48%), high alumina (Al2O3 > 48%). 4, Fusion-cast refractory material refers to a kind of refractory product that melt the batch through some certain methods refractory products, and then pouring into a certain shape. 5, Neutral refractory materials mean that under high temperature, don’t react with acidic or alkaline slag. 6, Special refractory material is a new type of inorganic nonmetal material, which is developed on the basis of traditional ceramic and refractory materials. 7, The amorphous refractory material is a mixture of refractory aggregate and powder, binder or admixture, which can be used directly or after adding the appropriate liquid mixing.
- Q: What are the grades of refractory exterior wall thermal insulation materials?
- Classification of fire rating of extrior thermal insulation materials 1, According to national standard GB8624-97, the combustion performance of building materials are divided into the following grades A level: Incombustible building materials: Materials hardly burn. B1 class: Flame-retardant building materials: Flame-retardant material has good flame resistance. In case of fire in the air or at high temperature, it is difficult to catch fire and the fire will not spread quickly. And when the combustion source is removed, the burning will stop immediately. B2 Class: Combustible building materials: Combustible materials have a certain flame retardancy. In case of fire in the air or at high temperature, it will immediately burst into flames and it is easily to spread fire, such as wooden column, wooden roof truss, wooden beams and wooden stairs, etc. B3 level: Inflammable building materials: It has no flame retardant effect, and it is extremely inflammable, and the risk of fire is high. Classification of exterior wall thermal insulation materials according to fire rating: 1. Thermal insulation materials with A-level combustion performance Rock wool, glass wool, foam glass, foamed ceramic, foam cement, hole-closed perlite, etc. 2, Thermal insulation materials with B1-level combustion performance: Extruded polystyrene board (XPS) after special treatment / polyurethane (PU) after special treatment, phenolic aldehyde, gelatine powder polystyrene granule, and etc. 3. Thermal insulation materials with B2-level combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
