Stemming used for blast furnace, coal mine water cannons mud, all kinds of physical and chemical indicators can be measured in a normal state, but into the interior of the blast furnace iron mouth, water cannons mud after sintering temperature mineralogical research and testing organization not directly, and thus more Temperature gradient changes, stemming supplier of coal mine water, the composite ratio of materials (stemming) the strength and characteristics of analysis and research of coal mine water stemming offer, use of stemming particularly important. Current development situation stemming: the major foreign iron production quality stemming countries have attached great importance to its development into two stages. The first stage is water cannons mud, and domestic similar, stemming manufacturer of coal mine water, in order to meet the production needs of modern large-scale blast furnace, blast furnace taphole improve the situation, the early 1970s to the early 1980s, around the world He launched a water cannons mud.
