Abstract: Refractory bricks are inorganic non-metallic products with a refractoriness of not less than 1750 °C. They are suitable for use in a variety of high-temperature kiln furnaces. The main function is to protect the steel structure of the furnace shell from melting at high temperatures. Function, the standard of refractory bricks is divided into: refractory brick physical and chemical indicators, refractory brick kiln masonry standards, refractory brick specifications and model standards.
Standard for refractory bricks - physical and chemical indicators
The physical and chemical indicators of refractory bricks are a measure of whether the material of refractory bricks can reach the environment in which kiln working conditions are used. It is also the basis for the constant price when purchasing refractory bricks. It is the only evidence for the production quality of refractory brick manufacturers. As the basic standard, raw material standard, compact shaped refractory product standard, insulated refractory product standard, amorphous refractory standard, five major categories, including 150 kinds of implementation standards, if you need a certain national standard, please contact Zhengzhou Yuda New Materials Technology Co., Ltd. can send an electronic version.
Standard for refractory bricks - kiln masonry
The masonry of refractory brick kiln shall be carried out in accordance with the construction and acceptance specifications of GB 50211-2004 industrial furnace masonry. The standard specifies refractory materials including refractory materials, refractory ceramic fibers, blast furnaces and their associated equipment, coke ovens and coke dry quenching equipment, steelmaking furnaces and related equipment, heating furnaces, heat treatment furnaces and annealing furnaces, flash furnaces, Aisa Furnace, rotary smelting furnace, ore electric furnace, horizontal converter, stationary refining furnace and rotary refining furnace, aluminum electrolysis tank, carbon calcining electric furnace and carbon roaster, glass kiln, rotary kiln, lime kiln and its subsidiary Equipment, tunnel kiln and roller kiln, reformer and cracking furnace, industrial boiler, winter construction, acceptance data, oven, construction safety and environmental protection.
Refractory brick standard - specification model
The specification type of refractory brick refers to the length and length of the refractory brick. The type of refractory brick is divided into general type, special-shaped model, general-shaped model, special-shaped model, etc. according to the external dimensions and the shape of the refractory brick. The use unit will jointly customize the size of the refractory bricks when both parties know each other.
