摘要： PROBLEM TO BE SOLVED: To raise working efficiency to maximum and automatically control a tank charging work by avoiding conflict between a plurality of tank charging works, computing a tank charging work beginning time, a completing time, and a tank charging quantity practicable for making the working efficiency to maximum under the restricted condition, and controlling receipt, delivery, and carrying facilities. SOLUTION: Imaginarily regarding that a system for blast furnace and a system for sintering ate independent of each other, a mixed integer programming is used to dissolve conflict. Respective tank charging plans are edited in order of the beginning time of the tank charging work at every original device and system, and output to an interface file outputting to a process computer setting control processing 110. Further, the stting control information is transmitted to a subordinary controller for controlling jobfield facility/device by the setting control processing 110, and a moving machine group and a belt conveyor group are automatically controlled by the time, the order, the using facility, the brand of material, and the tank charging quantity in accordance with the tank charging work plan. The computed result of the tank charging work planning function is presented to an operator in a CRT 119 through an operator input/output processing 107.

摘要： PURPOSE: To prevent the generation of a plane camber in a metallic sheet material when it is subjected to an edging process, by shifting a roll pair of a vertical roll stand, arranged on the runout side of a horizontal roll stand standing as the last stand in the rolling direction at that time, transversely to the lower temperature side as much as an amount corresponding to the transverse temperature difference in the metallic sheet material.
CONSTITUTION: A rolling work is applied to a metallic sheet material for reducing its breadth and thickness; for this purpose, a rolling mill line is constituted of a vertical roll stand V
1 , a horizontal roll stand H and a vertical roll stand V
2 , and the rolling work is performed in the direction of an arrow mark X. In this case, if the transverse distribution of temperature in the rolled material shows that the temperature on the driving side DS is relatively higher than the working side SW, the vertical roll pair of the stand V
2 , standing on the downstream side in the rolling direction, is shifted from a roll position shown by the dotted lines to a roll position shown by the full line, while keeping the vertical roll gap as it is, as far as a distance l to the working side WS that is the lower temperature side. As a result, any camber is not generated in the rolled material.

摘要： PURPOSE:To prevent the generation of the crack of the cast slab, by feeding the continuously cast hot slab to the hot rolling pass, after cooling the slab at a specified cooling rate and being subjected to the hot edging pass under a specified condition. CONSTITUTION:At continuously casting the molten steel, the slow cooling at the 1.0 deg.C/sec or less cooling rate is applied to the slab during the period ranging from the start of the casting work to the solidification/cooling point. Following to this, the slab is warmed at 950-1,300 deg.C for at least 10min in order to cause the transformation of the crack causing harmful precipitation so as to be harmless. Next, the warmed cast slab is subjected to the hot edging pass at the 5/sec or less strain rate and the 50mm./pass/one side or larger rolling reduction, and then, the slab is fed to the hot rolling pass. Hereby, the adjustment between the continuous casting pass and the hot rolling pass is maintained good, and the high productivity and the big energy saving ca be achieved.

摘要： PURPOSE:To carry a steel piece or the like being kept warm for improving the effect to roll it as such, by projecting the discs of disc rolls arranged in zigzag manner on the floor surface of a heat-retaining box whose entire surface is insulated from heat, and providing a means for piling cast pieces at the outlet zone of the box. CONSTITUTION:Hot cast pieces discharged from a continuous casting machine are piled up, mounted on a receiving table 9 by a crane or the like and charged in a heat-retaining box 1 whose front and back, right and left, and up and down surfaces, i.e. six surfaces in total, are insulated from heat. The top ends of disc rolls 4 arranged in zigzag manner along the direction of carrying the hot cast pieces are projected beyond the bottom surface of the box 1, to carry the cast pieces. The load of said rolls 4 is supported by back-up rolls 5. On the other hand, a lifting withdrawer 8 is provided at the outlet zone of the box 1, e.g. for gripping a hot cast piece S-2, lifting it (raising S-2-S-5) and expelling the lowermost hot cast piece S-1 onto a withdrawing table 10 by the rolls 4. In this way, the lowermost hot cast piece is continually expelled to inhibit the falling of a temperature.

摘要： PURPOSE:To prevent the generation of cracks during the continuous rolling pass, by previously rolling the continuously cast hot slab with a specified strain rate and a specified rolling reduction in the direction of the breadth, before feeding the slab to the hot rolling pass. CONSTITUTION:The cast slab of a specified breadth size at the surface and interior condition free from cracks is fed from the continuous casting pass to the hot rolling pass. That is, the molten steel is continuously cast and the hot cast slab is obtained; this hot cast slab is subjected to the hot edging pass with the 3/sec or less strain rate and the 50mm./pass/one side or larger rolling reduction; after that, the slab is fed to the hot rolling pass. Hereby, the continuously casting pass becomes possible to be connected and matched with the hot rolling pass at a high energy efficiency and the high productivity.
