Silica Bricks (T-3)

Silica bricks are acidic refractory materials and have good resistance to acidic slag erosion. The load softening temperature is as high as 1640~1670℃, and the volume is relatively stable under long-term use at high temperatures.

Description of Silica Bricks

It is mainly used for the partition walls of the carbonization chamber and combustion chamber of coke ovens, the regenerators and slag chambers of steel-making open-hearth furnaces, soaking furnaces, refractory materials of glass melting furnaces and ceramic firing kilns, and other kiln vaults. Load-bearing parts. It is also used in high-temperature load-bearing parts of hot blast furnaces and acidic open-hearth furnace tops.

Features

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.

Silica Bricks for Coke Oven

Modern coke ovens are large-scale thermal equipment built with tens of thousands of tons and nearly a thousand types of brick refractory materials, of which silica bricks account for 60% to 70%. The main component of silica bricks for coke ovens is tridymite, which is mainly used to build coke oven regenerator walls, chutes, combustion chambers, carbonization chambers and furnace tops. Silica bricks for coke ovens mainly have the characteristics of high softening temperature under load, high thermal conductivity, good thermal shock resistance, and volume stability at high temperatures.
