Refractory Materials for Blast Furnace
Blast furnace is a large metallurgical equipment, usually made of steel structure and a variety of refractory materials, which is mainly used as a high temperature reaction furnace for converting iron ore into molten iron.
Blast furnaces are an important part of steel production, and their linings need to withstand high temperatures, high pressures, and the erosion of molten metal. The choice of refractory for the lining is based on the environment in which it is required.
The blast furnace can be divided into five parts, namely, furnace throat, furnace body, furnace waist, furnace belly and furnace cylinder. The temperature and environment of each part of the blast furnace are different, and the selection of refractory materials for lining is also different. Refractories for lining each part of the blast furnace should be reasonably selected according to the specific working temperature and working environment, so as to ensure the stability of the furnace body.
Blast furnace lining with refractory materials surrounded by the blast furnace type, blast furnace internal circular workspace, the size of the blast furnace to the effective volume of the number of cubic meters. In the blast furnace lining in the use of harsh conditions of the location of the cooling device protection, so that a generation of working furnace age can be up to 15 years or more.
