摘要： PURPOSE:To improve the setting accuracy of a flow rate, to facilitate the adjustment and to decrease the number of control loops for flow rate control by arranging plural flow rate control blocks which can be set to each prescribed throttling value in parallel with each other at the throttling mechanism of the draining side and switching freely a 3-way valve. CONSTITUTION:The water is sprayed to the steel stock carried in an attitude H through the multi-stage nozzle groups 13. Thus a flange is cooled. The stages of the groups 13 are selected by opening/closing a valve 7 in accordance with the width of the flange 14. Then plural control blocks are provided in order to satisfy the steel stock cooling conditions, and a cooling pattern is changed by switching a 3-way valve to the nozzle or draining side. The opening amount of an opening amount control valve 8 is obtained at every control block by reference to a computer table when the valve 7 is set. Then the opening amount of the valve 8 is set at the value set with coincidence secured between the pipeline resistance coefficients of the 3-way valve obtained at the nozzle and detaining sides respectively. Thus the flow rate can be easily adjusted, and the highly accurate control of the flow rate is attained together with the complicated switch of the 3-way valve.

摘要： PURPOSE:To enable easily the change in pass line in a short time by constituting a rolling mill of stationary outside and movable inside housings, supporting rolling rolls in the inside housing and making the same movable vertically. CONSTITUTION:The housing of a rolling mill is constituted of an outer housing 1 fixed to a foundation 2 and an inner housing which is made vertically movable by a pressing device. Rolling rolls 17 are provided in the inside housing, and the gap between the rolls 17 is adjusted with screw down devices 6 each consisting of a screw and a screw down motor. The inner housing is moved upward or downward when pressing devices 4 are operated, by which the pass line is changed easily. The rolling reaction to be generated when a rolled material is rolled with the rolls 17 is transmitted to stanchions 8 and beams 9 of the inside housing, but the devices 4 press both end parts of the beams so as to compress the stanchions 8; therefore, the deformation of the inside housing is prevented.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device for forming a plate capable of achieving a constant YR rising rate on YR rising section of the plate to prevent extremely-high YR generation after the plate is formed by pressing forming rolls. SOLUTION: The method and the device for forming the plate by pressing the forming rolls with circular arc shape surface on both surfaces of the plate, are characterized by that a hydraulic cylinder of a hydraulic power unit provides a thrust power between upper and lower forming rolls and the hydraulic power unit maintains the thrust power applied by the hydraulic cylinder during forming within a constant range. Especially they are those for manufacturing an electric resistance melded steel pipe, and the rolls with the thrust power between two forming rolls given by the hydraulic power unit are breakdown rolls for bending and correcting a central part in width of a coiled steel sheet.

摘要： PURPOSE:To enable free-size correspondence by changing rolls for a 2nd pass because the shape of caliber is a single circular arc, roll grinding is easy and the radius of caliber for a 1st pass is larger in the use range to the diameter on the inlet side. CONSTITUTION:A bar or wire rod is rolled with two three-roll rolling mill which the inclination of a regular triangle that is formed by the extensions of the axial lines of three rolls in a vertical plane is a arranged by shifting 60 deg.. The radius of the roll caliber for a 1st pass of rolling is made into 120-160% of the radius of the circle of a base stock 4 and that for the 2nd pass of rolling is in the range from the same to 110% of the radius of base stock. Each screw- down of roll of the rolling mills for the 1st pass and 2nd pass is independently operated and sizing is executed in the range from the diameter of base stock to at most 85% of the diameter of base stock. Thus, sizing rolling can be executed with high forming accuracy by a caliber shape of single curve and the frequency of roll change can be reduced by taking the sizing range by one roll wider.

摘要： PURPOSE:To perform repairing work in a short time for projecting the improvement of productivity, by cutting a damaged skid metal on the way at a position apart from a welded part between the skid metal and a skid pipe in a heating furnace, and welding a new one. CONSTITUTION:In repairing a damaged skid metal (e.g. a skid button), the upper half 4' of a refractory coating 4 is detached at first inside a heating furnace. Thereafter, the skid button 2 is cut off in a short time by a plasma arc at a position 7 in a fixed distance A (about 20-30mm.) apart from a welded part 6 between a skid pipe 3 and the skid button 2. A new skid button 2 having adjusted height is then added by welding, and refractory coating 4' is restored to finish execution. Said execution can be performed under the condition that cooling water is circulated through the pipe 3 in the oven.

摘要： PURPOSE:To minimize loss of thermal energy in the rolled process in such a way that after cooling off shot which has become high temperature condition by a shot cooler, it is supplied again to an injector for being re-used, and the high temperature rolled material is brought into being shot blasted as it is. CONSTITUTION:Shot injected from an injector 3 onto a high temperature rolled material (a) falls down for the most part into an injecting chamber 1, one part of which is put on the high temperature rolled material (a), and sent to the side of a blow-off chamber 18 of the shot. Then, the matter in the injecting chamber 1 among the shot which has become high temperature condition is carried by a conveyor 17, the matter sent into the blow-off chamber 18 carried by a conveyor 37, both of which are conveyed to a shot cooler 40 to be cooled off therein. The shot which has been cooled off is, then, carried out of a cooled shot outlet port 54 of the cooler 40 at a settled rate, supplied to an injector 3 of said injecting chamber 1 by a conveyor 61 at the underneath, ensuing high temperature rolled material (a) is continuously disposed of by shot blasting.
