Q: What are the electrical fire protection materials?: Inorganic binder: Water glass, gypsum, phosphate, cement, etc.; Refractory mineral filler: Alumina powder, calcium carbonate, asbestos, perlite, cornstarch; the main purpose of electrical fire prevention board is to prevent fire and heat. The heat conductive plate will conduct electricity, leading to good equipment insulation and large superheating surface! ! ! ! Hope my answer will help you.

Q: which kind of refractory is used in golden smelting furnace? How about his using temperature: generally the price of the quartz sand refractory material is higher and the temperature can meet the requirement of 2000 degree.

Q: What are the characteristics of thealuminium oxide refractory?: Physical properties of refractories include structural properties, thermal properties, mechanical properties, performance and job performance. The structural properties of refractories include porosity, bulk density, water absorption, air permeability and pore size distribution. The thermal properties of refractories include thermal conductivity, thermal expansion coefficient, specific heat, heat capacity, thermal diffusivity and thermal emission rate, ect. Mechanical properties of refractories include compressive strength, tensile strength, flexural strength, torsional strength, shear strength, impact strength, abrasion resistance, creep resistance, adhesive strength and modulus of elasticity, ect.

Q: Who knows the fire rating of fire?partition with steel stud?: 1 hour. It is in line with the fireproof test standards of national building materials . CaSo4.2H2O is molecular structural formula of gypsum which contains 20% water, crystal water and free water. When 10% water slowly evaporates on the flame surface, there is still 10% crystal water. Itself is grade A fire retardant material. It can reach up to four hours at most.

Q: Who knows which chrome refractories produced by the Henan refractory plant can be used for continuous casting?: Field casting experiments are needed to verify,

Q: How long is the duration of fire resistance that fireproof door of level B can endure?: Fireproof doors can be divided into three levels, namely level A,B,C. Fireproof doors of level A can endure fire for 1.50～2.00h while level B for 0.50～1.50h. However, according to national condition, the lowest fire doors fire resistance limit has been specified, namely, level A,1.50h;level B,1.00h; level C, 0.50h.

Q: What is high alumina refractory?: It refers to inorganic non-metallic material with refractoriness of higher than 1580℃. Refractoriness refers to the celsius temperature that the cone-shaped refractory sample without load can resist, and under which the sample won't soften and melt down. Refractory material appears together with high temperature technology, and roughly dates from the Middle Bronze age. In the Eastern Han Dynasty (AD25~AD220) of China, fireclay refractories has been used as furnace refractories and saggers for making porcelains. In the early 20th century, refractory material develops toward the direction of high purity, high dense and ultra high temperature products, and meanwhile unshaped refractory and refractory fiber with no need of firing at all and with low energy consumption appear.

Q: What's the frequently used refractory material?: Refractory material is generally used in industrial departments like metallurgy, glass, cement, ceramics, machinery, hot working, petrochemical industry, power and national defense. Frequently used common refractory: silica?brick, semi-silica brick, clay brick, high alumina brick, magnesia brick, etc. Frequently used special refractory: AZS brick, corundum brick, direct-bonded?magnesia-chrome?bricks, carborundum brick, calcium oxide, chromium hemitrioxide, alumina, magnesium oxide, etc. Frequently used fireclay insulating refractory: diatomite product, asbestos product, insulation?board, etc. Frequently used unshaped refractory: ramming refractory, refractory castable, plastic refractory, refractory mortar, gun-mix refractory, refractory coating, lightweight refractory?castables, etc.
