Q:who knows the uses of refratories?
Physical properties of refractories include structural properties, thermal properties, mechanical properties, usability and operation. structural properties of refractories include porosity, bulk density, water absorption, air permeability, pore size distribution. Refractory thermal properties include thermal conductivity, thermal expansion coefficiency, specific heat, heat capacity, thermal diffusivity, thermal emissivity. Mechanical properties of refractories include compression strength, tensile strength, anti bending strength, torsional strength, shear strength, impact strength, abrasion resistance, creep property, adhesive strength, modulus of elasticity. Refractories are used in various fields of steel, nonferrous metals, glass, cement, ceramics, petrochemical, machinery, boilers, light industry, power, military and other fields of national economy. They are essential materials that ensures the production run and technological development of the above industries, and play an important role in promoting the developemnt of high temperature industrial production. the usability of refractories include refractoriness, softening temperature under a fixed load, linear change on reheating,thermal shock resistant performance,slag resistance, acid resistance, alkali resistance, hydration resistance, carbon monoxide resistance, conductivity, oxidation resistance.
Q:A chemical problem with refractory materials
Not necessarily. What you mean is silicate
Q:How long is the fire resistance time of the AAAfire resistance rolling shutter door?
How long is the fire resistance time of the AAA fire resistance rolling shutter door?
Q:What are the refractories for converter?
Magnesia carbon material with large surface repair vessel, in addition to supporting the use of magnesia and magnesia cement.
Q:How is the performance of refractory materials?
It is a little difficult to answer. There are some requirement for refractory materials, such as fire resistance, softness, creep, thermal shock, abrasive resistance. Besides, requirements for construction performance include: Liquidity, plasticity and other linear change rate, volume density, strength (including high temperature) and all other important indicators must be tested the same conditions with the use of test conditions and test items like body density, strength, line changes in the basic project
Q:I wanna ask that magnesium oxide is refractory?
Magnesium oxide. magnesium oxide has high refractory insulation properties. After above 1000 ℃ high temperature burning, it can be transformed into crystals. And it can be transformed into dead-burned magnesium oxide or sintered magnesia oxide until rising to above 1500 ℃. It has heat-resistant, non-conductive at room temperature and relatively poor thermal conductivity. Magnesium oxide is mainly used for the preparation of ceramic, enamel, refractory crucible and refractory bricks. I hope to help you
Q:what's the varieties of fire-proof sealing material?
ATD-AB, organic fire-proof caulking, fire retardant bag, fire retardant net, fire retardant ring, fire barrier wrap, fireproofing sealing strip, flexibility fireproofing coiled material, fireproof glue, etc., fireproofing sealing materials currently on the market can be divided into two types, one is the traditional type: flexible organic caulking, WXY-II, fire retardant bag, fire bulkhead, cable refractory coating; there are some new materials used in large-scale projects: fireproofing coating board system (fireproofing coating board, intumescent fireproof sealing tape, elastic fireproof sealant, Waterborne Fire-retardant Coating), fire retardant module system (fire retardant module, sealing gum, cable refractory coating), fireproofing plaster system (fireproofing plaster, sealing gum, cable refractory coating).
Q:Kinds of refractory mortar
Refractory mortar can be divided into ordinary refractory material and special refractory material. Ordinary refractory materials can be divided into acidic, neutral and alkaline refractory materials chemical properties. Special refractory material can be divided into high temperature oxide, refractory compounds and high-temperature composite materials according to their components. Furthermore, according to refractoriness, it can be divided into general refractory products (1580 ~ 1770 ℃), high grade refractory products (1770 ~ 2000 ℃) and super refractory products (2000 ℃ above). It can be divided into bulks (standard bricks, special-shaped bricks, etc.), special shapes (crucible, sagger, pipe, etc.), fibrous (aluminum silicate, zirconia filter and boron carbide , etc.) and indefinite shape (refractory clay, pouring materials and ramming mass, etc.). According to the sintering process, it is divided into sintered products, fused cast products and melting jetting products.
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:What parts of cement kilns are refractories used on?
Generally they are used in cyclone, feed pipe, and duct and refractories are high-strength alkali-resistant castable, calcium silicate board, high-strength alkali-resistant brick, dome-shaped alkali resistant brick. Refractories in smoke chamber are high-alumina refractory castable, anti-skinning pouring material and calcium silicate board. Refractories in duct are high-strength alkali-resistant bricks, calcium silicate boards and steel fiber reinforced castable. Refractories in hooding parts of kiln are high strength castable high alumina and calcium silicate board. Refractories in rotary kiln are phosphate bonded high alumina brick, silmo brick, magnesia chrome brick, steel fiber reinforced castable. Refractories in grate cooler are vault alkali brick, high alumina refractory castable, steel fiber reinforced castable and calcium silicate board. Refractory in coal burner is dedicated castable for coal burner.
