摘要： PURPOSE:To operate charging device for material to be heated based on calculated result of shifting distance of shifting furnace hearth by detecting the dimension along charging direction of the material to be heated conveyed to charging side. CONSTITUTION:At the time of conveying the material to be heated to the charging side in a heating furnace, the dimension along the charging direction of this material to be heated is measured with dimension detecting instrument and the dimension detected signal is transferred to a sequence control system 5 and the shifting width of shifting furnace hearth suited to the size of charged material to be heated is calculated from the dimension detected signal and tracking information. The material to be heated is charged into the heating furnace with the charging device for the material to be heated, which is controlled in operation based on this calculated result.

摘要： PURPOSE:To detect a joint part at good accuracy by taking average of surface temp. in a cast slab before reaching to the joint part of the cast slab, making the valve subtracting the prescribed temp. from this average surface temp. the set surface temp. and detecting the part at the temp. less than this set surface temp. as the joint part of the cast slab. CONSTITUTION:A detecting instrument 9 is constituted of a non-contacting type thermometer 11 set on the upper part of the cast slab 6 at upstream side of a cutter 7 and a computer 12 outputting cutting signal to the cutter 7 after calculating the cutting position at front and rear parts of the joint part 10 of the cast slab based on the inputted signal from this thermometer. At the time of forming the joint part 10 in a mold 5 by exchanging a tundish 3, the computer 12 starts to execute the temp. measurement of the cast slab. Into the computer 12, the measured temp. is inputted, for example, at interval of two sec and these inputted temps. are averaged, for example, at interval of five min and subtracts the prescribed temp. to make the set temp. This set temp. is corrected at every five min and the cuttings are surely executed at the preset cutting positions of front and rear parts to the joint part 10 of the cast slab. Instead of the surface temp. by measuring surface light quantity, the joint part can be detected, too.
