Different working conditions for refractory brick in blast furnace

     All working environments for refractory brick in every party of the blast furnace are pretty bad and they are slightly different from each other.

Refractory Brick

     Last week, we have analyzed the working environments of the refractory brick in different parts of blast furnace. This week, we will continue to discuss bosh, hearth and bottom of the blast furnace.

     Besides of the application in furnace throat, body and waist, refractory brick can also be applied to the following parts of the blast furnace:

     Bosh connects the furnace hearth and waist. Its top part is large while the lower part is small, meeting the need of the increasing gas volume and the decreasing volume when furnace charge becomes iron slag. The inclination of the bosh should also be appropriate. In order to improve the burden permeability, bosh angle also becomes larger. Usually large and medium-sized blast furnace bosh has an angle between 80 and 82 degree. Besides, bosh bottom has high temperature and a large number of slag. So the slag erosion is so serious that it develops a weak part of the blast furnace.

     Hearth and bottom are mainly in charge of burning coke and storing iron slag. With the increasing intensity of iron making, furnace cylinder diameter is also growing, becoming the worst working environment part. Especially in the tuyere zone, temperature reaches the highest point with the lining suffering from high temperature and chemical erosion of iron slag. The bottom of the furnace is mainly subject to iron slag erosion, especially the erosion of molted iron liquid, forming garlic-shaped bottom. Due to the uneasy maintenance of hearth and bottom lining, the service life of hearth and bottom often determines the working length of the blast furnace.

     Look forward to your participation in the sharing of refractory and insulation industrial knowledge.
