Description

Slag disk residue crushing device Technical Field The utility model relates to the technical field of steel smelting, in particular to a slag pan residue crushing device. Background In the steel smelting process flow, after the high-temperature steel slag at 1400-1600 ℃ is poured into a slag pan, the steel slag is required to be naturally cooled to normal temperature and can enter a subsequent treatment link. In the process, due to the characteristics of the smelting process, a small amount of molten steel along with steel slag pouring can be naturally deposited at the bottom of the slag pan by virtue of the density advantage. When the temperature of the mixture of the molten steel and the steel slag is reduced to below 1200 ℃, the steel slag and the molten steel form a high-strength solidification combination at the bottom of the slag pan. The phenomenon causes that in the follow-up transfer dumping operation, the solidification mixture is difficult to be completely separated from the slag pan, so that the steel slag treatment efficiency is obviously reduced, the problems of residue accumulation of the slag pan, shortened service life of the slag pan and the like are more easily caused, the continuity of a smelting production line and the turnover efficiency of equipment are seriously restricted, and the problems become key bottlenecks affecting the production efficiency and the cost control. The traditional slag pan residue treatment mostly adopts gun machine operation, and the process has the defects of low treatment efficiency, high energy consumption cost, large noise pollution and the like. Disclosure of utility model The utility model aims to provide a slag pan residue crushing device which converts the dead weight of a slag pan into an unlocking power source of a crushing hammer based on a mechanical balance principle, realizes high-efficiency crushing of residue in the slag pan without additional energy driving, has a simple structure, is low in cost, is durable, greatly reduces manual intervention, and reduces the labor intensity of personnel. In order to achieve the above object, the present utility model provides the following technical solutions: The slag pan and residue breaking device comprises a crown block, a lifting appliance and breaking hammers, wherein the lifting appliance is connected with the crown block through a chain, the breaking hammers are hung on the lifting appliance, the crown block can lift the breaking hammers through the lifting appliance, after the crown block lifts the breaking hammers to a preset height, the breaking hammers can be automatically unlocked with the lifting appliance, and the breaking hammers fall into the slag pan to break residues in the slag pan.
