Hot billet, cold billet → inspection → rejection of unqualified billet→ heating in furnace → descaling by highpressure water →rejection of unqualified billet → roughing rolling (φ550*6) → No. 1 crank flying shear → medium rolling (φ450*6) → No. 2 rotary flying shear → ...
Abstract— According to research tests, the rollinganddrawing of metal in nondriven rollers reduces the rolling force by 30 to 32% as compared with the rolling in driven rollers. A new method of determining the friction coefficient for a modified process flow sheet is proposed. As shown by the calculations, continuous strip mills used in the rollanddraw mode cut the metal strain force by ...

Roller tables The roller tables consist of a series of roller either driven by line shafting and bevel gears from a common drive or by individual motors. In some improved designs, the bevel gears have been replaced with spur gears. The roller tables serve to feed the material being rolled into the rolls and receive it from the rolls.

In a hot strip mill, the hot rolled coils are produced from slabs through hot deformation and subsequent cooling with water on a run out table. In conventional rolling, the starting slab thickness is around 200 mm to 250 mm. On the other hand, in thin slab casting and rolling, the starting slab thickness is around 50 mm to 90 mm.

So were went with metal flat top tables open both ends, and problem solved. With the planer, I use a roller table as an outfield set at an angle so that it will cause the board to traverse out of the planer and line up with a waiting pallet. So small angles are easily accomplished with a roll table, but not a flat top metal or wood.
