Standard for refractory materials commonly used in 7 types of furnaces for industrial use

Date of release:2018-09-26 Author: Click:

Dry charging furnace plays an important role in the production of steel, aluminum, non-ferrous metals, glass, ceramics and other industries. According to the temperature of different parts of the furnace, different types of refractory materials are selected.

For example, the main aluminum smelting furnace is reverberatory furnace, converter and induction furnace, operating temperature is generally 700-1000 degrees Celsius. The lining of this kind of furnace is damaged mainly by the infiltration and erosion of aluminum liquid. The lining is usually made of clay brick, high alumina refractory brick and corundum mullite brick. It can also be made of high alumina refractory castable and refractory plastics.


Dry material introduction

Refractories for reverberatory furnaces



The furnace is divided into two types: fixed type and tilting type. Gas or heavy oil is usually used as fuel. Aluminum smelting is usually done in a fixed reverberatory furnace, and non-working layers are made of refractory fiber felt and clay insulated refractory bricks.



The working layer above the molten pool is made of clay brick. It can also be hoisted with high alumina refractory castable prefabricated blocks or poured on site or rammed with high alumina refractory plastic.
