Anhydrous stemming is to continuously improve the production of pig iron (especially after burning), with the traditional water stemming tadpole maintenance is not good situation, after repeated testing and improvement, a new type of refractory material is developed, which adapts some advanced refractory materials and chemical raw materials, with advanced and a unique process preparation, its advanced technology, excellent quality, less consumption, there is a water gun mud can not be comparable, the blast furnace iron mouth maintenance, flow stability, promote the safe production, plays a role is the key to reduce the accident potential. The main characteristics of anhydrous stemming: Compared with the traditional water gun mud, has the following advantages using anhydrous stemming: 1, less dosage, high strength. Anhydrous stemming each time only needs to install the 80-120kg, as the water gun mud made of new refractory materials, especially high strength, with clay content can be less ensuring tadpole depth; high temperature resistance, anti slag erosion, non stick iron slag, iron mouth without baking, is another characteristic of anhydrous stemming, from the tadpole maintenance is very convenient. 2, flow stability, an accident is not easy. The anhydrous stemming high strength, using drilling drilled iron mouth aperture always remains the same size; ensure the hot metal flow uniformity, reduce or avoid running large flow, diffuse iron slag, explosion accident occurred. At the same time, can greatly reduce the labor intensity of workers. 3, ensure net iron slag, promoting the furnace, using anhydrous stemming generally, aperture iron mouth than the use of water stemming from aperture small, under the same pressure, anhydrous stemming, can fully guarantee the blast furnace slag and iron out net, the hearth, active space, and promote the furnace operation, and is conducive to strengthening smelting, improve the management of the production of pig iron.
