Embodiment Construction
[0016] Such as figure 1 Shown, the embodiment of the present invention a kind of waste iron and steel processing recycling method, comprises the following steps:
[0017] 1) Screen the recycled scrap iron and steel to remove impurities in the scrap iron and steel;
[0018] 2) Cut the screened scrap iron and steel by shearing machine, collect the dust by dust removal equipment and clean the cut scrap iron and steel.
[0019] 3) Crushing the sheared scrap iron and steel segments through a crusher;
[0020] 4) The broken steel scrap is sent to the surface stripping machine through the belt conveyor for surface treatment to obtain steel concentrate.
[0021] A preferred embodiment, in step 4), the crushed iron and steel scrap is first magnetically separated by a magnetic separator and then transported to the surface stripping machine by a belt conveyor, which can further improve the recycling of iron and steel scrap accuracy.
[0022] Preferably, in step 3), when crushing scra...

The invention discloses an iron and steel scrap processing and recovery method which comprises the following steps: 1) screening recovered iron and steel scrap, and removing impurities in the iron and steel scrap; 2) shearing the screened iron and steel scrap with a shearer, collecting dust with a dust removing plant, and cleaning the iron and steel scrap subjected to shearing; 3) crushing the iron and steel scrap sections subjected to shearing with a crusher; and 4) sending the crushed iron and steel scrap to a surface stripper with a belt conveyor, and carrying out surface treatment to obtain the refined iron and steel. The recovered iron and steel scrap is processed by the steps of impurity removal by screening, shearing, crushing and surface stripping, and the iron and steel scrap is subjected to dedusting and cleaning after shearing, thereby enhancing the precision of the refined iron and steel, improving the processing and recovery rate and providing more profits for the enterprise.
Description
technical field [0001] The invention relates to the field of iron and steel recycling, in particular to a method for processing and recycling scrap iron and steel. Background technique [0002] Improving the recycling of scrap iron and steel plays a very important role in the sustainable development strategy of the iron and steel industry. The processing and recycling of scrap iron and steel can reduce resource and energy consumption and reduce environmental pressure.
