Problems solved by technology
[0003] In the traditional steel slag water quenching method, since the residual steel and liquid steel slag are not effectively separated before water quenching, the residual steel is prone to explosion when in contact with water, which poses a large safety hazard to users, affects the normal production of steelmaking, and reduces the cost of users. The economic and social benefits of
The traditional steel slag water quenching method has a small ratio of water, which leads to poor slag granulation effect, and the particle size of steel slag granulation cannot well meet the needs of sintering, steelmaking and related industries

Abstract
The invention discloses a steel slag water quenching treatment system and mainly aims to provide a steel slag water quenching treatment system which is high in safety and slight in pollution. The steel slag water quenching treatment system comprises a slag ladle, and a steel slag separation device arranged outside the slag outlet of the slag ladle, wherein the steel slag separation device comprises an intermediate container in a slope structure and a filter tip arranged at the bottom of a container platform; the system also comprises a secondary water quenching pool and an overhead type steam extraction hood arranged above the secondary water quenching pool; the steam extraction hood is connected with a steam extraction centrifugal fan by virtue of a steam extraction pipeline.
Description
technical field [0001] The invention relates to the technical field of steelmaking equipment, in particular to a steel slag water quenching treatment system. Background technique [0002] Iron and steel enterprises are the basic industry of the national economy. With the rapid development of the national economy, steel production has been increasing in recent years. In 2012, the annual output of crude steel has reached about 717 million tons. Steel slag is a derivative of the steelmaking process. With the improvement of production, the output of steel slag is also increasing. According to the latest statistics, the utilization rate of steel slag in my country is only 30% to 40%. The data shows that the utilization rate of steel slag is very low, and it is still far from the goal of "zero discharge" of solid waste in iron and steel enterprises. [0003] In the traditional steel slag water quenching method, since the residual steel and liquid steel slag are not effectively se...
