Rapid water-cooling and air-cooling system for metallurgy

Abstract

The invention relates to the technical field of metallurgy. The invention discloses a rapid water-cooling and air-cooling system for metallurgy. The system comprises a base, a slag box is arranged atthe upper end of the base; a box cover is arranged at the top end of the slag box; an air box is arranged at the upper end of the box cover; a slag inlet is formed in one side, close to the air box, of the upper end of the box cover; and the side face, close to the box cover, of the output end of the compressor communicates with a liquid inlet pipe. A liquid outlet pipe communicates with the side,close to the liquid inlet pipe, of one side face of the box cover, one end of the liquid outlet pipe is connected with a metallurgical furnace, an inner furnace is arranged in the metallurgical furnace, a preheating cavity is formed between the metallurgical furnace and the inner furnace, and a first circulating pipe is arranged in the preheating cavity. The rapid water-cooling and air-cooling system is simple and convenient to operate, water cooling and air cooling are integrally matched, dual cooling is achieved, the rapid cooling efficiency of high-temperature metallurgical slag can be further improved, and meanwhile the high-temperature recycling efficiency generated by the high-temperature metallurgical slag is achieved.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a rapid water-cooling and air-cooling system for metallurgy. Background technique [0002] Metallurgy is the process and technology of extracting metal or metal compounds from minerals, and using various processing methods to make metal materials with certain properties. Metallurgical technologies mainly include pyrometallurgy, hydrometallurgy and electrometallurgy. With the development of my country's iron and steel industry and the increase in demand for iron and steel, the discharge of metallurgical slag, especially blast furnace slag and steel slag, as a by-product in the iron and steel production process, has also increased year by year. [0003] However, the traditional treatment of high-temperature metallurgical slag is not perfect. Due to its high discharge temperature and large output, the efficiency of waste heat recovery and utilization is poor, which will easily ca...

Problems solved by technology

[0003] However, the traditional treatment of high-temperature metallurgical slag is not perfect. Due to its high discharge temperature and large output, the efficiency of waste heat recovery and utilization is poor, which will easily cause a great waste of resources and energy, and will also cause great pollution to the environment; and the existing Most of the high-temperature metallurgical slag is cooled by a single water cooling method, which has a poor effect on the rapid cooling of metallurgical slag
