摘要： PROBLEM TO BE SOLVED: To prevent segregation, particularly when the density at the center part is enhanced simultaneously, and to obtain a uniform strand (cast slab) over the cross section of the strand by using the drawing force of the strand as the control value for adjusting the position at the tip part of an unsolidified part in the case slab while comparing the position of roll pair, and also a gap between the rolls. SOLUTION: As an actual value, a rolling reduction force P in the prescribed roll pair 23 in the deforming gap of the roll pair 23 executing a deformed section, a deformed thickness ΔD and the strand drawing force Z obtd. depending on a material characteristic value, are set, and the necessary toque to the following driving roll 22 is calculated. At this time, the reference value is the drawing force obtd., when the tip part S of the molten metal or the end part of the solidification directly exists in the gap of the rolls 24, 25. In the deviation between the actual value and the reference value, the correction of the positional relation between the roll pair 23 and the tip part S of the molten metal is executed with the change in casting speed or the change of the position of the roll pair 23.

摘要： PROBLEM TO BE SOLVED: To provide a method and equipment to deform a strip for a strip mill which supplies the strip to a coiler by means of a feeding mechanism consisting of upper and lower feed rollers after the strip passes through a finish rolling line and a cooling section. SOLUTION: In an area between the end portion of a cooling section 2 and a coiler 4 where a strip 5 is reduced in thickness, at least two rollers or rolls 3' and 9 are provided up and down in such a way that they form a smaller roll clearance than the thickness before the rollers or rolls as seen in the strip threading direction.

摘要： PROBLEM TO BE SOLVED: To reduce the trouble and the cost in fitting of a screwing piece into a mold assembling inner plate and to avoid the treatment for the large quantity of contaminated copper caused at the time of exchanging the worn mold assembling inner plate by inserting a packing piece providing a coupling material detachably into an undercut part provided in a groove formed between webs and providing a screw coupling part between the packing piece and a water storing box. SOLUTION: A packing piece 7 is provided with a coupling member 9 and the coupling member 9 has the coupling member thickness (c). The coupling member 9 is inserted into an undercut part 6' separatably together with a rotating member 10. The rotating member 10 is rotatable with a rotating axis 10 as the center and in a rotating plane 12 erected perpendicular to the rotating axis 11, the rotating member 10 has the max. length and the max. width. The coupling member 9 comes out of the packing piece 7 by the rotation of the rotating member 10 in the rotating plane 12. In this way, the coupling member 9 can be inserted separatably in the undercut part 6'. Therefore, the packing piece 7 can be coupled with a mold assembling inner plate 1 integrally.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device for monitoring and regulating the quality of coating layers subjected to a galvannealing treatment of a strip right after galvannealing. SOLUTION: The visible appearances of the coating layers subjected to the galvannealing treatment as the measured values for the quality of the coating layers subjected to the galvannealing treatment of the strip 16" are detected in the form of the measurement signals as quality measured values by visible recorders 15 and are evaluated by a measurement technique. The resultant measured values are converted to regulated values and are thereafter used for direct control of an annealing furnace 12. At least one visible recorder is disposed and detect the coating layers subjected to the galvannealing treatment of the strip 16" by the measurement technique. In addition, the recorder is integrated to a controller of the annealing furnace 12 via a control/evaluation device 17.

摘要： PROBLEM TO BE SOLVED: To easily decide a pass schedule policy by measuring the hardness of a material to be worked just before a cold deformation, correcting a strain hardening curve with the measured value and adjusting cold rolling equipment based on the corrected strain hardening curve. SOLUTION: A reference strain hardening curve of a material having reference values such as hardness, a yield point and tensile strength is corrected with hardness to be measured. When rolling is executed, the difference between pre-calculated rolling force and rolling force to be actually measured is used for correcting a calculation for calculating the rolling force. Hardness is preferably measured in many positions of the material and an EQOTIP measuring method is preferably utilized. A temperature and surface friction of the material are also measured to preferably make a parameter of the strain hardening curve. Hardness is preferably measured when rolling work is stopped, for example, when welding work is executed and when a plate thickness is measured or the like.

摘要： PROBLEM TO BE SOLVED: To obtain a mold which improves the surface quality of a cast slab, particularly avoids the development of a longitudinal crack or restrains this crack to the min. limit, by reinforcing the back surfaces of wide side walls with a wall armoring part starting from the bath surface level of the deepest position and having the thickest part thereat and gradually tapered shape in the casting direction. SOLUTION: One of two wide side walls 2 which are mutually faced and complemented in a continuous casting mold 1, is provided with a pouring port 3 on the inside for housing an immersion tube and a cooling groove 4 for passing water on the outside. Edge part ranges extended in the narrow side direction near the pouring port 3 on the wide side wall 2 are mutually directed in the parallel direction. Thereat, the back surfaces 10 of the wide side walls 2 are reinforced with the wall armoring part 11 which starts from the bath surface level of the deepest position and has the thickest part thereat and the gradually tapered shape in the continuous casting direction 6. In this way, the sharp temp. drop at the lower part of the projecting part in the temp. expanding part is weakened and the temp. introducing over the whole body in the width and the height directions of the continuous casting mold 1 is uniformly executed.
