Problems solved by technology

[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. Improper methods, such as improper classification and extraction, will cause the recycled steel to not be fully utilized and cause unnecessary losses

Embodiment Construction

[0016] A continuous casting production process of scrap iron and steel, the processing steps comprising:

[0017] 1) Scrap steel is magnetically separated by a magnetic separator for the first time, and then transported to the shearing machine by a belt conveyor;

[0018] 2) Cut the scrap iron and steel after magnetic separation by a shearing machine, and then transport it to the dust removal equipment for cleaning by a belt conveyor;

[0019] 3) Transport scrap iron and steel to the crusher for crushing through the belt conveyor;

[0020] 4) The crushed steel scrap is magnetically separated again by a magnetic separator, and then transported to a surface stripping machine by a belt conveyor for surface treatment to obtain iron and steel concentrates.

[0021] 5) The iron and steel concentrate processed by the surface peeling machine is cleaned again by dust removal equipment;

[0022] 6) Smelting in a blast furnace, using molten steel to blow argon to obtain refined molten ...

Abstract

The invention discloses a continuous casting production process of steel scrap. The processing steps include: 1) magnetically separating the scrap steel through a magnetic separator for the first time; 2) shearing the scrap steel through a shearing machine; 3) crushing the scrap steel with a crusher; 4. ) Magnetic separation by magnetic separator, and surface treatment in the surface stripping machine to obtain iron and steel concentrate; 5) Cleaning by dust removal equipment; 6) Smelting in a blast furnace, using molten steel to blow argon to obtain refined molten steel; 7) Continuous casting process is carried out after the refined molten steel is added into the alloy to obtain the continuous casting slab. The method of the present invention processes the recovered steel scrap through the steps of screening and removing impurities-screening scrap iron-shearing scrap steel-crushing scrap steel-surface peeling scrap steel, which can improve the precision of iron and steel concentrates and carry out continuous casting after adding alloys to the refined molten steel The continuous casting slab is obtained by processing, the quality of the continuous casting slab is improved, and the economic benefit is improved.

Description

technical field [0001] The invention relates to the field of iron and steel recycling, in particular to a continuous casting production process of 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. Improper methods, such as improper classification and extraction, will cause the recycled steel to not be fully utilized and cause unnecessary losses. [0003] After the molten steel produced by the converter is refined in the refining furnace, the molten steel needs to be cast into billets of different types and specifications. The continuous casting section is the production process of continuously casting the refined molten steel into billets. The ladle containing the refined molten steel is transporte...
