WEAN UNITED , CONTIN. HOT STRIP ROLLING MILL (8 STANDS)
WEAN UNITED , CONTIN. HOT STRIP ROLLING MILL (8 STANDS)
Technical information
Extra info
This continuous hot strip rolling mill is ideal for high quality strip production starting from thick slabs.
The hot strip mill takes the slabs from the reheat furnace and by reversing them through 3 roughing stands and then through 5 finishing stands which reduces them to a thickness range from 1,5 to 10,5 mm.
Material: carbon steel & stainless steel
2 000 000 ton per year capacity = 166 666 ton per month capacity
Input slab thickness range: 150 > 250 mm
Input slab width range: 600 > 1560 mm
Input slab length range: 4900 > 5500 mm
Output plate thickness range: 1,5 > 10,5 mm
Output plate width range: 600 > 1564 mm
Total roughing mill power: 12000 hp
Total finishing mill power: 23500 hp
