Description

Silica lattice bricks are used as carriers of high-temperature heat. Its working principle is to first burn coal gas, use the high-temperature flue gas generated to heat the checker bricks in the regenerator, and then heat the cold air through the hot checker bricks, causing the hot air stove to rotate alternately. Carry out combustion and air supply, and continuously obtain high-temperature hot air in the blast furnace. The function of the hot blast furnace is to heat the cold air sent into the blast furnace by the blower into hot air, and then send the hot air into the blast furnace through the hot air duct for combustion reaction.

During the air supply period, the cold air blown by the blower enters the hot air furnace, is heated by the checker bricks into hot air, and is sent to the blast furnace through the hot air duct. Checkered bricks are mainly used in hot blast stoves. When the hot air temperature is lower than 900℃, clay is generally used. When the air temperature is higher than 900°C, the material of the checker bricks is high alumina, mullite, sillimanite, and silicon.

Characteristics of Silicon Checker Brick:

Ferrosilicon furnace is an industrial electric furnace that consumes a lot of power and is a type of submerged arc furnace. Ferrosilicon furnace includes furnace shell, furnace cover, furnace lining, short net, water cooling system, smoke exhaust system, dust removal system, electrode shell, electrode pressure release and lifting system, loading and unloading system, controller, burn-through device, hydraulic system, transformer And various electrical equipment, etc., the use of refractory materials is also quite demanding.

In 2006, Our factory was founded in Yuzhou, the raw material base.High bauxite ore is a finely divided colloidal mixture composed of aluminum hydroxides and various ratios. High-alumina bauxite in the refractory industry usually refers to bauxite ore with a calcined Al₂O₃ content greater than 48% and a low Fe₂O₃ content.

Silicon lattice brick application

Silicon check bricks are mainly used in hot blast stoves. When the hot air temperature is lower than 900℃, clay is generally used. When the wind temperature is higher than 900℃, the silicon grid bricks are made of high alumina, mullite, sillimanite and silicon.

Under the same conditions, large blast furnaces use traditional 7-hole bricks with a diameter of 30mm and 19-hole bricks with a diameter of 43mm, which increase the air temperature by 38°C; small and medium-sized blast furnaces use 19-hole bricks with a diameter of 25mm and 31-hole bricks, which increase the air temperature by 19°C.
