There are more than a dozen varieties such as carbon scrap, alloy scrap, steel scrap, iron scrap, oxide scrap, light and thin material, and steel slag. According to different specifications and quality requirements, reasonable planning and classification of varieties, even if they are fully utilized, are beneficial to production. Scrap iron and steel are roughly divided into four categories and more than a dozen varieties according to the current customary classification.

4. Acceptance criteria for recycled steel scrap
Reheated carbon scrap includes ordinary carbon scrap, high-quality carbon structural steel, carbon tool steel and carbon spring steel. The company’s scrap steel acceptance standard is the "Enterprise Standard" formulated by Shougang, which stipulates in SG/JS010-1996:
4.1 System scrap steel: the thickness is more than 2mm, and the length is not limited.
4.2 Qualified steel scrap: thickness above 2mm, length below 700mm.
4.3 Steel scrap
4.4 Heavy scrap steel
The thickness is more than 10mm, the length is less than 1000mm, and the width is less than 400mm. (Outer profile size≦1000mm×500mm×400mm). The shape is block, such as steel rails, train axles, large gears, billets, cutting heads, cutting tails, large channels of steel castings, I-beams, etc., are judged as heavy scrap steel according to the actual situation, and the profile size is judged to be too long Extra long heavy steel scrap.
4.5 Lightweight materials
4.6 Miscellaneous iron
Refers to waste pot iron, gray iron, white iron, cast iron pipe fittings, etc.
4.7 Standards for briquetting and frying steel are determined according to the needs of converter and electric furnace steel production.
