Abstract

The invention relates to a melted steel dreg spiral crushing device and method. The melted steel dreg spiral crushing device comprises a dreg tank (1), a rollover machine (2), a spiral crusher (3), aslag groove (4), a dreg discharging machine (5), a hot suffocating tank (6), a flue gas treatment system and a control system (12); the rollover machine is used for pouring dreg; the fixed shaft of the spiral crusher can be used for continuously crushing melted steel dreg; the melted steel dreg can be continuously poured into the spiral crusher; the spiral crusher is used for crushing the steel dreg and driving the steel dreg to a dreg outlet while being rotated according to a certain speed; the device has the advantages that continuous production of steel dreg treatment is realized, a previous batch production manner is changed and the steel dreg treatment efficiency is greatly improved.

Description

technical field [0001] The invention relates to a spiral crushing device and method for molten steel slag, in particular to a spiral crushing device and method for high-temperature molten steel slag produced in the production process of iron and steel enterprises. Background technique [0002] my country is a major producer of steel, with an annual steel output of more than 800 million tons, accounting for more than half of the world's total. About 120kg of steel slag is produced for every ton of steel produced, and the annual production of steel slag is more than 100 million tons. Steel slag contains iron metal resources and inorganic material resources such as calcium silicate, which has important resource recovery value. my country's iron ore resources have been imported for a long time, and various resources are in short supply. Therefore, the treatment and resource utilization of steel slag has great significance in resource recovery value. [0003] Whether it is to ...
