T/TWhat is refractory wet mud?
The water -based binding agent is called a water cannon mud. Organic materials such as tar, resin and other organic materials are called water -free mud.
Cannon mud composition can be divided into two parts -refractory aggregate and binding agent. Fire resistance refers to the refractory raw materials such as Gangyu, Mo Lai Shi, Coke Gemstone, and coke, coke, Yunmu and other modified materials. The binding agent is organic materials such as water or tar and phenolic resin, and also adds SIC, SI3N4, expansion and external agents. The aggregate is based on a certain particle size and weight. It has certain plasticity under the blending of the binding agent, so that the iron water can be used to beat the iron mouth through the mud gun.
Taking pure coking oil as a binding agent, the coking hardrobe temperature is about 200 ° C; if it is a coke-asphalt composite binding agent, its scorching temperature is about 360 ° C. Due to the high focusing temperature of asphalt, the zoom nodular value of asphalt has become higher. Among them, the amount of coking oil also affects the softening point and scorch value of the asphalt.
The fire -resistant material used to block the iron outlet can be divided into two categories: water cannon mud and waterless gun mud. On large and medium -sized blast furnaces on high top pressure and high degree of smelting.
The main function of refractory wet mud:
1) Blocking the iron mouth, requires good filling and sinterability;
2) Stabilize the iron, requiring cannon mud to open the iron mouth and erosion to resist;
3) Protect the furnace cylinder, require no cracks when the mud is heated quickly, and the combination of the old and new gun mud is high;
4) The opening performance is good, and the drill of the opening machine is easy to drill;
5) Moderate plasticity, which is convenient for mud artillery operation and forming iron mouth mud bag;
6) Good volume stability, small changes at high temperatures, will not be caused by shrinkage and leakage.
Advantages of Waterless Cannon Mud:
1) High intensity, and it is of great significance to maintain the stable stability of the blast furnace (the depth of the iron inlet, the time fluctuation of the iron outlet, the full wind blocked mouth, etc.), so that the blast furnace has the basis of increasing production.
2) Strong resistance to slag. The mud single is low, generally one -fifth of the water cannon mud.
3) There is a certain expansion performance. The combination of this artillery mud has a suitable pore rate and strength, which can adapt to large blast furnaces with more than 2000m³ or more.
