Steel slag centrifugal granulation device

Abstract

The invention belongs to the technical field of ferrous metallurgy, and specifically relates to a steel slag centrifugal granulation device. A centrifugal disc is set to have a conical pendulum structure so that the splashing route of melted steel slag fluctuates periodically, thus all areas of a cooling water sleeve can be evenly impacted by steel slag, the cooling effect becomes more uniform, and at the same time, the service life of a slag tank is prolonged. A first cleaning head and a second cleaning head are arranged on the valley and peak of a steel slag splashing route; then the rotation speed of the cleaning heads is set to be identical with the speed of the conical pendulum of the centrifugal disc; thus the first and second cleaning heads can always avoid the steel slag splashingroute; and real-time online washing of the cooling water sleeve in the slag tank is realized. A slag-water separating device can directly collect steel slag and wastewater generated during the steel slag granulation process and carries out cooling, washing, and separating immediately. The steel slag recovering and utilizing efficiency is improved. The steel slag is not piled up, waste heat or smoke is not generated, and the environment is protected.

Description

technical field [0001] The invention belongs to the technical field of iron and steel metallurgy, and in particular relates to a steel slag centrifugal granulation device. Background technique [0002] Steel slag is a by-product of the steelmaking process, which is formed by the oxidation of silicon, manganese, phosphorus, sulfur and other impurities in pig iron during the smelting process and the salts formed by the reaction of these oxides with solvents. composition. There are two main ways to comprehensively utilize steel slag as a secondary resource. One is to recycle steel slag in our factory as a smelting solvent, which can not only replace limestone, but also recover a large amount of metallic iron and other useful elements from it; , construction materials or raw materials for agricultural fertilizers. The treatment of steel slag mainly includes processes such as water quenching, granulation, cooling, cleaning, and powder grinding. However, the process of steel sla...

AI Technical Summary

Problems solved by technology

The treatment of steel slag mainly includes processes such as water quenching, granulation, cooling, cleaning, and powder grinding. However, the process of steel slag treatment in the prior art is relatively scattered, the equipment occupies a large space, and the production efficiency is low. It is difficult to adapt to the fast-paced metallurgical industry. production demand
