Yangquan Zhiyao Refractories Co., Ltd. is a high-tech enterprise specializing in R&D, production, and sales of shaped and unshaped products. The company is located in Yangquan City, Shanxi Province, where there are abundant bauxite resources, and the surrounding railway, high-speed, and aviation road networks are densely trafficked and very convenient.
The company’s main business: refractory bricks, high alumina bricks, clay bricks, and other shaped refractories; high alumina castables, lightweight castables, refractory castables, and other unshaped refractory materials. It is applied to a variety of industrial furnace bodies of many super large and large enterprises in building materials, ferrous and non-ferrous metallurgy, machinery manufacturing, chemical industry, and other industries.
Refractory brick material classification can be divided into ordinary refractory brick products (1580~1770℃), refractory products (1770~2000℃), and refractory products (above 2000℃) according to the shape and size. According to the shape and size, it can be divided into standard type, Special-shaped bricks, special-shaped bricks, large-shaped bricks, and special supplies such as crucibles, dishes, tubes, etc. for laboratory and industrial use. According to the molding process, it can be divided into slurry casting products, plastic molded products, semi-dry pressed products, tamped molded products from powdered non-plastic clay, and products cast from molten materials.
The load softening temperature of refractory bricks is the corresponding temperature at which different degrees of deformation is produced under the action of high temperature and constant load, which is called the load softening temperature or simply the load softening point. When the refractory brick contains a glass phase, because the amorphous structure is irregular and the probability of collision between atoms is high, the thermal conductivity is lower than that of crystals. When the refractory brick contains pores, the thermal conductivity of the gas is smaller than that of the solid, so as the porosity increases, the thermal conductivity of the material decreases. This is the basic reason for the low thermal conductivity of porous materials.
|High alumina brick|
|Starting temperature of load softening ℃ (0.2MPa)||≥1510||≥1490|
|Reburning line changes(1500℃*2h)%||+0.1,-0.5|
|Compressive strength at room temperature||≥39.2||≥34.2|
1) Tracking of kilns in cement and other building materials industries;
2) Furnace lining stories in petrochemical, metallurgy, ceramics, and glass industries;
3) Back insulation of heat treatment furnace;
4) The non-ferrous metal industry deviates from insulation;
5) High-temperature reaction, heating equipment back blood.
