Main components:
The mud pack ramming mass produced by our company is made of main raw materials including high-quality brown corundum, bauxite, silicon carbide and carbon materials, a variety of additives and imported resin.
Main features:
After the new blast furnace or the overhauled blast furnace, the mud that is pressed into the blast furnace is not easy to form a mud pack, and even if it is formed into a mud pack, its strength does not meet the requirements for tapping. The mud pack made of by our company has high strength, and the depth of the iron mouth can be made according to requirements to meet the requirements of tapping. In addition, in the initial stage of tapping, the mud pack can be effectively formed to protect the mud sleeve and prolong the service life of the mud sleeve. At the same time, at the beginning of the tapping, a suitable iron mouth depth can be formed to meet the iron demand. In the process of tapping, the influence of the pressure in the furnace is small, the iron flow can be stabilized, and the iron outlet iron stability can be ensured.
