Pyroxene refractory bricks for hot blast furnace

A hot blast stove is a high-temperature heating equipment that is used for processes such as heat treatment or drying in industrial production. In order to ensure the stability and durability of the high-temperature environment in the furnace, the hot blast furnace often uses andalusite refractory bricks as the lining material.

Andalusite refractory brick is a high-performance refractory material with excellent high temperature resistance and erosion resistance. Its main components are high-purity alumina and aluminium silicate, as well as a small amount of additives. Andalusite refractory bricks made by a special process have a high melting point and thermal shock resistance, and can withstand extreme thermal expansion and contraction in a high-temperature environment. At the same time, andalusite refractory bricks also have excellent chemical stability, which can resist acid and alkali corrosion and gas erosion in the furnace.

In the hot blast furnace, andalusite refractory bricks are used as lining materials, which can effectively isolate the high-temperature furnace and the external environment, prevent energy loss, and ensure the stability of the temperature in the furnace. The excellent fire resistance and erosion resistance of andalusite refractory bricks can greatly extend the service life of the hot blast furnace, reduce the frequency of maintenance and replacement, and improve production efficiency and economic benefits.

Therefore, andalusite refractory brick is an ideal lining material in the hot blast furnace, which provides a reliable guarantee for the normal operation of the hot blast furnace through its high temperature stability and corrosion resistance.
