Problems solved by technology

[0006] The difficult problem of efficient recycling of large slag steel produced by desulfurization slag treatment is mainly reflected in three aspects: first, the water quenching effect of desulfurization slag is poor, and it is easy to form large slag mounds at the bottom of the slag tank; second, the crushing process is produced offline The process is extremely long, resulting in extremely low processing efficiency and high cost; third, the traditional processing and crushing technology is backward, and general crushing equipment cannot meet the processing requirements of large slag mounds, resulting in a large amount of slag and iron lumps that cannot be used and can only be piled up

Abstract

The invention discloses a method for treating desulfuration slag through a grating. According to the method, the assembled grating is placed in a desulfuration slag tank in advance, liquid slag pouring is conducted, segmentation or separation is conducted through the grating, and finally, natural segmentation is realized, so that production of 'large slag blocks' is avoided; and residual steel slag after treatment can also be used as a raw material for machining grating prefabricated panels and can be recycled. By the aid of the method, the level and the capability of recycling of slag steel can be strengthened, the efficiency of slag block treatment and the comprehensive utilization level are greatly improved, and environmental pollution and space waste are reduced.

Description

technical field [0001] The invention relates to a treatment process for desulfurization slag. The desulfurization slag is divided and separated by grids, and finally realizes natural disintegration, avoiding the generation of "big slag mounds", improving the comprehensive utilization level of steel slag, avoiding environmental pollution and space waste . Background technique [0002] With the development of the steel industry, the amount of steel slag has also increased. At present, there are many desulfurization slag and steel slag treatment processes, the most direct one is to excavate and load the hot-melt steel slag after water quenching treatment with loader, drop hammer, slag breaker, electric shovel and other equipment, and then transport it to the waste slag In this way, the storage of desulfurization slag not only takes up a lot of cultivated land and pollutes the environment, but also 20-40% of the recyclable iron in the steel slag is wasted. [0003] In the ...
