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.

Anhydrous tap hole mix for blast furnace tap hole
Refractory ramming mass (refractory taphole mass) is a kind of Refractory used for lining of blast furnace tapping groove. It is mainly used to protect the blast furnace out of the ditch from high-temperature hot metal and slag erosion and erosion, and has excellent high-temperature resistance and wear resistance. The ramming material for the iron discharge ditch is usually composed of corundum, silicon carbide and carbonaceous material, which has the ability of resisting hot metal and molten slag erosion and scouring, reburning line change small, strong resistance to a variety of oxidation characteristics. The construction of the ramming material for the iron ditch is convenient, easy to dismantle and repair, does not produce harmful gas, and is beneficial to environmental protection.
In the blast furnace smelting process, blast furnace taphole clay, as a key plastic material, plays a vital role. This article will introduce in detail the product characteristics, working principle and innovation of blast furnace taphole clay in improving furnace stability and production efficiency.
Anhydrous taphole mud/taphole clay refers to taphole mud made of tar, resin, etc. as binders and corundum, bauxite, clay, silicon carbide, coke powder, etc. as raw materials. Anhydrous carbon taphole mud is made by a mud mill. When rolling, oil is added first, then block materials (clay and asphalt), and then powder materials (coke powder and clinker powder) are added after crushing. After pressing and mixing, the mud can be produced when it meets the standards.
We specialize in producing various types of tap hole clay. Our tap hole clay protects the blast furnace hearth, increases production and saves costs! We are your best choice for tap hole clay suppliers.
It is widely used in the lining of the kiln working face which is in direct contact with the flame, and has become one of the research hotspots in recent years.
Refractory castable is a kind of refractory material that does not need to be formed and has good fluidity after being fired and stirred with water.
