Description

Converter slag pot Technical Field The utility model relates to the technical field of metallurgical equipment, in particular to a converter slag pot. The slag pot is mainly used for containing, transporting and treating high-temperature slag in the converter steelmaking process, and the structural design is suitable for severe working conditions such as high temperature, strong corrosion and the like in the metallurgical industry, and can effectively improve the efficiency and safety of converter slag treatment. Background In the existing metallurgical production process, a converter slag pot is used as key equipment for containing high-temperature slag generated in converter steelmaking, and the use of the converter slag pot has some problems to be solved urgently. The traditional converter slag pot adopts a pot body structure made of single material, and the phenomena of abrasion, cracking and the like are easy to occur at the bottom and the side wall of the pot body in the process of long-term corrosion of high-temperature slag with the temperature of more than 1500 ℃ and frequent loading and unloading and transportation, so that the service life of the slag pot is short, frequent replacement is required, the production cost is increased, and the production efficiency is also influenced. Meanwhile, the traditional slag tank has poor heat dissipation performance, when the high-temperature slag is stored in the tank for a long time, heat is difficult to effectively dissipate, the temperature of the tank is easy to be overhigh, the ageing and damage of tank materials are further aggravated, and the overhigh temperature can also bring potential safety hazards to transportation equipment and surrounding environments. In addition, when the slag is discharged from the traditional slag pot, because of unreasonable structural design, slag is easy to remain in the pot, not only is the waste of resources caused, but also extra manpower and time are required for cleaning, and the production complexity is increased. Disclosure of utility model In order to solve the problems of short service life, poor heat dissipation performance, slag discharge residue and the like of the traditional converter slag pot in the prior art, the utility model provides the converter slag pot, which improves the high temperature resistance and the wear resistance of the slag pot, enhances the heat dissipation effect, reduces slag residue, prolongs the service life of the slag pot, reduces the production cost and improves the production efficiency and the safety by optimizing the structural design and the material selection. The converter slag pot comprises a pot body, wherein the pot body is composed of an inner layer, an intermediate layer and an outer layer. The inner layer is made of high-alumina refractory materials, has excellent high-temperature resistance and slag erosion resistance, can be directly contacted with high-temperature slag, and can effectively protect other structural layers of the tank body. Furthermore, the middle layer is a heat insulation and dissipation layer and is formed by staggered arrangement of porous ceramic materials and heat dissipation copper pipes. The porous ceramic material has good heat insulation performance, can reduce the heat transfer to the outside, and meanwhile, the porous structure is beneficial to the flow of air and assists in heat dissipation, and the heat dissipation copper pipe is internally provided with a circulating cooling medium channel which is connected with an external cooling system, so that the heat in the tank body can be taken away in time, and the heat dissipation efficiency is further improved.
