摘要： PURPOSE:To permit control of the width drop to be generated at the front and rear ends of a sheet bar with good accuracy by determining the contact length between the parallel parts of dies and slab so as to minimize the width deviation of the cross rolling reduction at the longitudinal ends of a rolling stock predicted from specific conditions. CONSTITUTION:The position at the front end of the slab 3 conveyed by table rollers 4 is measured by a measuring roll 5 turning in contact with the front surface of the slab 3, a length measuring instrument 6 mounted thereto and a slab front end detector 7. The result of the measurement is inputted to a controller 8. On the other band, the shape (thickness, width) and cross rolling reduction of the slab 3 are preliminarily inputted to the controller 8. The temp. of the slab 3 is measured on the inlet side of a press by a themometer 9 and the result of the measurement is transmitted to the controller 8. The optimum length of the parallel parts of the dies and the slab is calculated from the specific conditions including the slab thickness, slab width, slab temp. and the cross rolling reduction by the press. The position of a table driving motor 10 is controlled in accordance with the result of the calculation.

摘要： PURPOSE:To extend the life of work rolls by setting the work roll position at the time of starting a rolling cycle on the outside of a stationary work, then executing roll movement and rolling within said stroke range after the arrival at the stationary stroke. CONSTITUTION:The transition of the uneven abrasion loss Cp in the initial period of the rolling cycle of the work rolls depends largely on the first 1/2 period. The pattern in the initial period of the rolling cycle is started from the range on the inside or outside of the ordinary stroke S and the rolling is executed by determining the stroke of the first 1/2 period as S0. The uneven abrasion loss Cp is decreased to 1/2 as compared to the case in which the shifting is not executed according to the above-mentioned method. As a result, the transition of the uneven abrasion loss Cp1 in the initial period of the rolling cycle coincides with the transition thereof when the shift stroke S is increased. Since the uneven abrasion loss Cp is minimized in the above-mentioned manner, the life of the work rolls is extended.

摘要： PURPOSE:To prevent the increase of a sheet crown when the abrasion wear of a roll increases by gradually decreasing the max. value and min. value of a roll shift with an increase in the number of rolling coils. CONSTITUTION:The shift stroke l of the roll is increased to prevent the thermal crown and the local wear of the roll when the number of the rolling coils counted from a roll exchange is small and the abrasion wear w is small. The extent of the movement of the shift stroke l is gradually increased to change the shift method to the shift method shown by a solid line 1 when the abrasion wear w increases with an increase in the number of the rolling coils. The increase of the sheet crown when the abrasion wear of he roll increases is thereby prevented without spoiling the function to prevent the wear of the abnormal roll and the function to disperse the thermal crown.

The average area of through-holes on the central layer is 20mm or less. The thickness of the central layer is specified as t(mm) and the sum of thickness of both surface layers is specified as T(mm) and the product of the ratio t/(t+T) of thickness (t) of the central layer to the thickness of sheet t+T and the area rate R of through-holes is specified as 0.1-0.6. Also, regularity degree parameter S is regulated as S
