Description

The equipment for water quenching includes a water quenching granulation head, a granulation tank, a slag grab, a slag buffer bin and the like. The equipment for air quenching also includes an air quenching granulation head, a granulation tank, a scraper, a dehydration bin and the like. The converting slag after granulation is temporarily buffered and dehydrated in the bin for a certain period of time, and then is transported by a vehicle to a converting slag storage of a smelting furnace in a raw material area which is far away. In the process of transportation, on the one hand, the water which is not completely dehydrated drips along the way to cause environmental pollution, and the converting slag also scatters in the transportation process to also cause pollution and loss of valuable metals. On the other hand, the cost of vehicle transportation is high, and the non-timely transportation is not conducive to the stability of production and even needs to stop the furnace. The working area of the slag grab is limited, and the materials accumulated in the granulation tank outside the working area of the slag grab need to be manually cleaned in a limited space to keep the channel in the working area of the slag grab smooth.
