Refractory Checker Bricks

Product Introduction

Refractory Checker Bricks is a thermal regenerator widely recognized and accepted by the world ironmaking industry in recent years. It has excellent thermal performance such as strong heat exchange capacity, large heat storage area, smooth ventilation, and low resistance. It is also a good heat transfer medium, which is mainly used for heat accumulation in the upper and middle parts of the heat accumulator of the hot blast furnace. As the carrier of high-temperature heat, the working principle of this product is to burn the gas first, heat the checkered bricks in the heat storage with the generated high-temperature flue gas, and then heat the cold air through the hot checkered bricks. The hot blast furnace alternates combustion and gas supply to make the blast furnace continuously obtain high-temperature hot air.

Application

The Refractory Checker Bricks are mainly used for hot blast stoves. When the temperature is under 900℃, fire clay brick is used; while the temperature is higher than 900℃, the material of checker brick should be high alumina, mullite, sillimanite, silica, etc.

Standard Size
