Rotating disc type granulating tank device for hot steel slag

Abstract

The invention relates to hot steel slag granulating equipment, in particular to a rotating disc type granulating tank device for hot steel slag. The rotating disc type granulating tank device comprises a tank body and a driving assembly. A feeding inlet is formed in the top of the tank body. A discharging outlet is formed in the bottom of the tank body. The top of a main shaft of the driving assembly is placed in the tank body. A rotating disc type granulating assembly placed in the feeding inlet of the tank body is arranged on the top of the main shaft. A spraying assembly is arranged on the upper portion of the interior of the tank body. According to the rotating disc type granulating tank device, fluid steel slag, semifluid fusion steel slag, sparse slag, bonded slag and semisolid fusion steel slag generated in a steel mill are all can be granulated and subjected to airtight water quenching treatment, and the purposes of separation on site and recycle after machining of the steel mill steel slag are achieved; and the steel slag is subjected to water quenching on line in a short time to be steel slag particles with the particle size being 3-20 mm and the high glass phrase, and the cost of transporting, rough crushing, middle crushing and fine crushing after the steel slag is cooled is saved, so that the steel slag treatment cost is reduced greatly, and great significance on steel mill scrap steel recycle cost reducing, steel slag crushing cost reducing solid, waste recycling and steel slag stacking environmental pollution reducing is achieved.

Description

technical field [0001] The invention relates to hot steel slag granulation equipment, in particular to a hot steel slag rotating disk type granulation tank device. Background technique [0002] Shougang Qiangang’s 210-ton converter steelmaking produces about 440,000 tons of steel slag every year. After the molten steel slag is transported to the slag bridge, it is dumped in the slag pool. After being bored for 18 hours, the steel slag is hydrolyzed and cracked into slag blocks of about 200mm. The loader loads them into special railway trucks and transports them to the slag yard for crushing. They are broken into slag blocks of about 25mm. The slag steel is selected from them by magnetic separation and sent back Steel slag is used as solid waste for secondary steelmaking in steel mills. The annual cost of steel slag transportation, crushing, and magnetic separation is about 35 million yuan, and due to the large size of steel slag crushing, the separation of slag and steel is ...
