What are the properties and applications of refractory materials?
If you want to produce good quality refractory materials, you need a good equipment. Shenyang Pengcheng Non-metal Equipment Co., Ltd. is a company specializing in the production and sale of refractory brick grinders. Let us understand the refractory materials. A non-metallic material with a fire resistance of not less than 1580 ° C, good resistance to thermal shock and chemical attack, low thermal conductivity and low expansion coefficient. Today Xiaobian takes everyone to understand the performance and application of refractory materials:
performance:
Mechanical properties
Compressive strength, tensile strength, flexural strength, torsional strength, shear strength, impact strength, abrasion resistance, creep, bond strength, elastic modulus, etc.
Physical properties
Structural properties, thermal properties, mechanical properties, serviceability and workability
Use performance
Fire resistance, load softening temperature, reburning line change, thermal shock resistance, slag resistance, acid resistance, alkali resistance, hydration resistance, CO erosion resistance, electrical conductivity, oxidation resistance, etc.
Structural performance
Porosity, bulk density, water absorption, air permeability, pore size distribution, etc.
Thermal performance

application:
"Refractory materials are used in various fields of the national economy such as steel, non-ferrous metals, glass, cement, ceramics, petrochemicals, machinery, boilers, light industry, electricity, military industries, etc., and are essential basic materials to ensure the production and operation of these industries and technological development It plays an irreplaceable role in the development of high-temperature industrial production.
Refractory is the basic material in the field of high temperature technology. Refractory materials are more commonly used as structural materials and linings that resist high temperature effects in various thermal equipment and high temperature vessels. In the steel and metallurgy industry, coke ovens are mainly composed of refractory materials. Blast furnaces and hot blast furnaces for ironmaking, various steelmaking furnaces, soaking furnaces, heating furnaces, etc. are indispensable for various refractory materials that meet the requirements.
