A recycling device for light and thin steel scrap

technical field

The invention relates to the field of scrap steel recycling, in particular to a recycling device for light and thin scrap steel.

Background technique

It plays a very important role in the sustainable development strategy of the iron and steel industry. The processing and recycling of scrap steel can reduce resource and energy consumption and reduce environmental pressure. The recycling of existing scrap steel is mainly supplied to steelmaking converters for recycling. Recycling in the blast furnace process can improve the recycling efficiency of light and thin steel scrap and improve the recycling of scrap iron and steel. Therefore, the light and thin steel scrap in scrap steel needs to be processed in advance.
