摘要： PURPOSE:To measure stress distributions in the width direction of a belt-like magnetic material instantaneously by dividing magnetostrictive sensors to two groups, and moving the respective groups in the width direction in conformity with the respective end part positions in the direction of the belt-like magnetic material. CONSTITUTION:The 1st magnetostrictive sensor group 42 and the 2nd magnetostrictive sensor group 44 consisting of plural pieces of L-shaped magnetostrictive sensors 40 are so arranged as to be moved in the width direction by means of a positioning cylinder. The sensors 42, 44 are so disposed that the respective sensors 40 are located specularly symmetrically with respect to the centerline C of a rolled steel plate 18, whereby the stress detecting positions of the groups 42, 44 are made symmetrical on the right and left. When tension acts in the rolling direction, differences are generated in the voltage detected by the coils 66, 68 in the respective directions, and from these voltage differnces, the stress distributions of the plate 18 are determined.

摘要： PURPOSE:To control the surface roughness of a cold rolled thin steel sheet with high accuracy by subjecting the steel plate to final rolling by making use of the coeffts. of influence of the rolling load and/or rear tension in a final rolling mill determined with respect to the surface roughness and the deviation value with respect to target surface roughness. CONSTITUTION:The coefft. of influence (1/Kp) of rolling load upon surface roughness in a final rolling mill 1 as well as the coefft. of influence of rear tension in the mill 11 upon the surface roughness are respectively determined beforehand and are stored in an operator 12. The target surface roughness X0 determined by the degree of surface finish and sheet thickness in the final product state of a cold rolled thin sheet is set in the operator 12; at the same time, the detected surface roughness X on the outlet side of the mill 11 which is measured 13, the actually measured rolling load P and the actually measured rear tension T are read therein. The operator 12 determines the deviation DELTAX between the roughness X and the roughness X0, and when the value DELTAX exceeds a blind zone (d), the operator operates the corrected rolling load P1 necessary for bringing the roughness X to the roughness X0 in accordance with the equation by using the above-described coeffts. (1/Kp). When the value P1 is in a prescribed permissible range, the operator transmits the load P1 as target rolling load P0 to a rolling reduction control device 14 which corrects the rolling load to the permissible threshold.

摘要： PURPOSE:To produce a grain-oriented silicon steel sheet excellent in surface characteristics with high productivity by subjecting a hot-rolled plate of a silicon steel containing specific amounts of C and Si and small amounts of inhibitor to cold rolling, process annealing, scarfing by grinding, and further cold rolling. CONSTITUTION:A hot rolled plate of a silicon steel having a composition containing, by weight, 0.02-0.1% C, 2.5-4.0% Si, and small amounts of inhibitor is cold-rolled twice or more while process-annealed between the cold rolling stages so as to be formed into the final sheet thickness. Subsequently, the resulting cold-rolled sheet is subjected to decarburizing annealing and then to finish annealing, by which a grain-oriented silicon steel sheet is obtained. At this time, after the above process annealing, the surface of the steel sheet is scarfed by mechanical means, preferably, after oxide scales are removed by a mechanical or chemical method, and then, cold rolling is performed. Further, it is preferable to carry out at least the final pass in the cold rolling before decarburizing annealing by using work rolls of

摘要： PURPOSE:To Perform stable cold rolling and to improve the product yield by supplying a roll coolant amount bringing an oil film thickness at a roll bite inlet point to be a necessary min. thickness decided by consideration of an advance ratio, rolling load, and sheet surface roughness. CONSTITUTION:For cold rolling, data obtained from a sheet thickness gage 2, sheet speed meter 3, sheet surface roughness measuring instrument 4, roll speed meter 5, and load meter 6 is sent to a computer 7. A necessary min. spraying amount by which an advance ratio, rolling load, and sheet surface roughness do not exceed a prescribed range is calculated and a coolant spraying amount is adjusted based on the calculated value. As the result, when the spraying amount control is carried out, all of a rolling load, advance ratio, and surface roughness remain within allowable limits as a rolling speed is raised to perform good cold rolling. Thus, generation of slips and shape defects is well prevented, sheet breakdown is not generated during rolling, and surface quality is also improved.

摘要： PROBLEM TO BE SOLVED: To improve the opening property of a scoring part and the safety after opening a can by forming a score part of an open end with pre-shearing from one direction and with return shearing from the reverse direction. SOLUTION: In the score part formed with pre-shearing from one direction and with return shearing from the reverse direction after then, in the time of opening, crack is advanced with the stress concentration caused on acute notches existing on front and back faces. Because a central part to be advanced with the crack is already received with large repeat shearing strain even without generating breaking, the ductility of the material itself is reduced and the crack is advanced easily. Further, in the final shear breaking position (burr generating position), because it is positioned at inner part in the wall thickness direction against the original metal sheet, the ductility of the material is inclined to reducing, so a large burr is not generated, in consideration of the state of generation, the anxiety of a cut of hand or finger, etc., is nothing in the real using.
