Description
Technical Field
The utility model relates to the technical field of steel making, in particular to a device for thermal-state forming and curing treatment of continuous casting residues.
Background
The continuous casting residual slag refers to residual steel residual slag left in a steel ladle and a tundish when the steel ladle and the tundish are replaced in the continuous casting process of a steel plant, and also comprises residual steel residual slag left in the steel ladle after special steel production mold injection. So far, most of steel works at home and abroad adopt the processes of hot splashing method, high-pressure water quenching method, disc splashing water quenching method, dry slag method, drop hammer method, cutting method and the like. However, the treatment process has the following problems.
1) Adopts the treatment processes of hot splashing method, high-temperature water quenching method and disc splashing water quenching method. The steel slag is poured out in a liquid state and is treated disorderly, more unorganized high-temperature steam is generated during water spraying and cooling, the steel slag can be splashed when meeting water, the working environment is severe (high temperature, dust and mist), and great personal safety hidden dangers exist. And because the steel content of the casting residue is large, the molten steel becomes large scrap steel after being condensed, and the subsequent transportation, cutting, sorting and recovery treatment are very difficult. And dust and waste water generated in the treatment process can cause serious pollution to peripheral areas and underground water.
2) Adopts dry slag method, drop hammer method and cutting method. After the slag is solidified into a solid state in the slag tank, the whole slag is poured out, and then the comprehensive process of a drop hammer method and a cutting method is adopted for treatment. The process overcomes the defects and dangerous sources of high temperature, dust and steel slag splashing when meeting water, but increases a lot of problems. On one hand, the slag is integrally solidified in the slag tank, sometimes steel slag blocks are bonded with the slag tank, the steel slag blocks are not easy to fall off, and the slag tank is seriously deformed and damaged; on the other hand, the steel slag blocks are too large, and the steel slag blocks must be processed by a drop hammer method, a cutting method and other processes, so that the processing difficulty is high, and the processing is labor-consuming, time-consuming and material-consuming. In addition, the scrap yield is reduced by the cutting method due to the burning loss.
In view of the above, further improvement and improvement are needed in the conventional casting residue treatment method and apparatus.
An effective solution to the problems in the related art has not been proposed yet.
