Description

4 Hi Hot Rolling Mill is a type of rolling mill used in metalworking, particularly in the steel and aluminum industries, to reduce the thickness of metal slabs at high temperatures. The hot rolling mill includes four rolls arranged in a vertical stack, including two work rolls (smaller in diameter, in direct contact with the hot metal), two Backup rolls (larger in diameter, supporting the work rolls to prevent bending under high rolling forces). The whole 4 Hi Cold Rolling Mill is composed of heating furnace(which preheats slabs before rolling), descaling device(which removes oxide layers before rolling), cooling system (which controls temperature during rolling), Coilers (which winds the rolled strip into coils)

Application

Hot rolling mills are essential in metal processing industries, primarily for shaping large metal slabs into thinner, more usable forms while the material is heated above its recrystallization temperature.Following some applications:
1. Steel Industry
 Production of Hot Rolled Coils (HRC): Used in automotive, construction, and appliances.

 Plates & Sheets: For shipbuilding, pipelines, and structural beams.

 Railroad Rails & Wheels: High-strength tracks and components.

 Structural Shapes: I-beams, channels, and angles for construction.
•
2. Aluminum Industry
 Aluminum Plates & Sheets: For aerospace, automotive (body panels), and packaging (cans).
 Foils & Thin Strips: Further cold-rolled for food packaging and electronics.
3. Copper & Brass Industry
 Copper Strips & Plates: For electrical wiring, transformers, and heat exchangers.
4. Special Alloys (Stainless Steel, Titanium, etc.)
 Stainless Steel Sheets: For kitchenware, medical equipment, and chemical tanks.
 Titanium Plates: Aerospace and military applications.
