Standard Size Lightweight Refractory Bricks Clay Insulating Blocks With CE Certificate

overview of fire clay insulating bricks

Fireclay insulation brick is a kind of lightweight refractory products, its aluminum ₂O₃ content is 18%-46%. Bulk density 0.8-1g/m³ . It is made of clay clinker or light clinker and plastic clay as the main raw material, usually produced by fuel method, but also by chemical method or foaming method to form a porous structure. Applicable temperature range is 900℃ to 1300℃, Firing temperature range: 1580℃ to 1770℃,can withstand high temperature environment.

applications of fire clay insulating bricks

. Metallurgical Industry This is one of the largest application fields of refractory clay insulation bricks. Iron smelting system: Furnace lining: The insulation layer for the furnace body, furnace waist, furnace belly and other parts of the furnace, which protects the furnace shell, lowers the surface temperature and reduces heat loss. Hot blast stove: As the insulation layer for the dome of the hot blast stove, the combustion chamber, and the walls of the heat storage chamber, it is of vital importance for increasing the air temperature and saving energy. Steel-making system: Steel ladle/Intermediate ladle: As a permanent layer, it is constructed between the working linings (such as magnesia-carbon bricks, castable materials) of the steel ladle and the intermediate ladle and the steel shell, serving the functions of insulation and protecting the steel shell. Rolling steel system: Heating furnace: Widely used in the furnace top, furnace walls and furnace bottom of push-type and step-type heating furnaces. As a heat insulation layer, it can significantly reduce fuel consumption.

II. Building Materials Industry Cement Industry: Cement rotary kiln: Primarily used as the insulation layer for the kiln tail preheater system, decomposition furnace, kiln door cover, cooling machine and other equipment. It does not directly come into contact with high-temperature flames, but can effectively maintain the system temperature and improve thermal efficiency. Glass Industry: Glass melting kiln: It is used for heat preservation of the bottom of the kiln, insulation of the abutment walls, and heat preservation of the storage chambers, etc. It has a significant effect on maintaining the stable temperature inside the kiln and reducing energy consumption. Ceramic industry: Tunnel kilns, shuttle kilns, and belt kilns: These are indispensable thermal insulation materials for the kiln bodies and kiln carts of various ceramic kilns. They are used on the kiln roof, kiln walls, and kiln cart tabletops, effectively improving the uniformity of the kiln interior temperature and saving fuel.

III. Petrochemical and Chemical Industries Petrochemical facilities: Ethylene cracking furnace, hydrogen production reformer, steam boiler: The furnace walls of these large thermal equipment usually adopt a structure of "fire-resistant working surface layer + insulation brick layer", and clay insulation bricks are the ideal insulation material. Coking Industry: Furnace: Thermal insulation for the furnace doors, riser pipes, and heat storage chambers of the coke oven.

IV. Mechanical Manufacturing and Heat Treatment Industry Heat Treatment Furnace: Such furnaces as annealing furnaces, normalizing furnaces, tempering furnaces, and carburizing furnaces generally adopt refractory clay insulation bricks as the insulation layer for the furnace body structure, in order to ensure uniform furnace temperature and process stability.

V. Electric Power Industry Power Station Boilers: In the boilers of coal-fired power plants or waste incineration plants, the parts of the furnace walls that do not come into direct contact with the flame are used as insulation materials.

VI. Other Industrial and Civilian Fields Garbage Incinerator Non-ferrous metal smelting furnaces (such as insulation layers for aluminum and copper smelting furnaces) High-temperature muffle ovens and box-type furnaces used in the laboratory.
