Application :
High alumina refractory cement CA50,have passed the ISO international quality certifify.According to the different content of Al2O3,they can have totally foue types:CA50,CA60,CA70 and CA80.They have the advantage of longer setting time,can resist high temprature,better stability in air,rapidly strength,no addivity and suitable for confect all kinds of castables and low cement refractory castables,refractory concrete,ramming mixes, gunning mixes and manmade marble bricks etc.
- Q: What are unshaped fire-resisitance materials?
- Refractory castable, refractory plastic material, usually classified according to construction and manufacture method, unfired bricks precast block, refractory pressed into material, refractory cast material, refractory coating, refractory ramming material there are many classification methods
- Q: Procedures for producing common refractory materials?
- The general procedures of producing refractory materials include calcination of raw materials, selection of raw material , crushing, grinding, screening, mixing, ageing mixture, molding, drying, burning and etc. At present, the refractory factory usually purchases the calcined clinker, so the calcination of raw material is no longer a consideration of common refractory plants.
- Q: How is the grading of the level A new material fire insulation material?
- The standard to distinguish level A and level B is the different fireproofing coefficient. The level A is non-combustible. The level B is divided into B1, B2 and B3. B1 is flame retardant, B2 combustible and B3 flammable. The level A is commonly phenolic aldehyde, rock wool, thermal?mortar, foam ceramics, foam glass and foam concrete on the current market. Among the advantages of level A materials, the biggest one is foam concrete currently, also known as foam cement, which the Xuzhou Green Year EEB company's main produces.
- Q: Which kind of furnace hearth refractory is better?
- Coal is acidic medium, so the matched material should be acidic refractories oriented, like silica?bricks. For example, the coking coke oven and carbon furnace made of carbon are in reducing atmosphere, so they use silica bricks which have low price and good high-temperature indicators. If the part has special requirements, you can then consider other refractory on request.
- Q: Ask some questions about refractories
- Is a kind of refractory material, jargon called hook materialThe iron runner: a combination of the super high Los resistant technology, aluminum and corundum, silicon carbide and other raw materials, to high-quality composite binders and additives, strict proportioning, elaborate. The utility model has the advantages of good slag resistance, good thermal shock resistance, long service life, convenient use, simple construction, and obvious reduction of labor intensity of workers.Application: it is suitable for blast furnace tapping system.
- Q: What crusher is used for raw material of broken refractory material? What is the rough crushing process? What are the materials? Thank you!
- What is said above ia wrong. Crusher choosed by general refractory material factory is roller type, for example: Roll crusher,teeth-roller?cracker. Choose different crushing equipment according to your requirements. You can go "Zhengzhou Keda Machinery Co., Ltd." to inspect! ! ---Hope it is helpful to you!
- Q: Which brand of refractory fiber hard thermal insulation board is better?
- Luyang ceramic fiber semi-hard board is good for it has typically applied major technological performance industrial furnaces backing, wall lining, lining material, electric heating furnace backing lining heat insulation ceramics shuttle kiln, backing lining of tunnel kilnand roller kiln.
- Q: The manufacturing technique of refractory material
- Melt blowing method is to melt the ingredients first, In addition, hiphotos, organic impurities, to be mixed, add sulfite pulp waste liquid into magnesia billet , ensure the accuracy of the product dimension. The products are mainly used for light refractory. then dry and fire with sintering to reduce the firing shrinkage of products, making it disperse into fiber or hollow sphere. The porpose of pre sintering raw material is to Sintering method is pre-sintering part of the raw material into clinker. such as adding binding clay into aluminum silicate blank
- Q: On the problem of making refractory materials
- But if only a is chosen, does it mean that as long as it is insoluble in water, it can be made of refractory material? Obviously absurd!
- 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.
