摘要： PURPOSE: To enhance wear resistance and to facilitate exchange by forming the front end of an impactor of sintered ultrahard chips and dividing joining bases for mounting these material pieces at the impactor to a plurality in the radial direction of a revolving rotor/or the direction of a spindle. CONSTITUTION: The impactor 10 consists of an impactor body 11, the plural joining bases 14 mounted in socket and spigot parts 13 formed in its step part 12 and the sintered ultrahard chips 15 fixed respectively by brazing to the respective joining bases 14. The respective joining bases 14 are freely attachably and detachably fixed to the impactor body 11 by means of bolts 17. The sintered ultrahard chips 15 are joined to the joining bases 14 by pressure thermal welding, laser welding or the like, by using sandwich solder. The sintered ultrahard chips 15 and the joining bases 14 for mounting the same are divided to a plurality in the radial direction of the revolving rotor 5 and the direction of the spindle 4 thereof. The sintered ultrahard chips 15 may be used by inverting the chips upside down together with the joining bases 14 when the front ends thereof wear.

摘要： PURPOSE:To improve the efficiency of a coiling operation by providing a measuring cylinder, disposing a stopper mechanism to set the forward and backward moving range of the piston thereof and further communicating the cylinders for expansion and contraction and for measurement by two fluid transport lines. CONSTITUTION:The measuring cylinder 31 having the same piston stroke volume as the stroke volume of a driving cylinder 30 for expansion and contraction is provided on a base plate 9 and the stopper mechanism constituted of a screw 32b at the end of the piston rod 32a thereof, a stopper 33, and a nut 34 is dis posed. Both cylinders 30, 31 are communicated by pipelines 21a, 21b, 40, 41, etc. The stop position of the piston 19a and rod 15 can be set as desired by adjusting the tightening extent of the nut 34 in the stage of synchronously moving the piston rod 32a and a wedge rod 15 by the movement of the pressure liquid according to the above-mentioned mechanism. Since the deterioration of a sleeve is dealt with by the above-mentioned method, the efficiency of the coiling operation is improved.

摘要： PURPOSE:To prevent the irregularity of paint concn. by allowing paint to flow under stirring, by partitioning a paint pan by a weir plate and sucking paint from the bottom of the tank in a pickup roll side to a tank part in the other side to recirculate the same. CONSTITUTION:The paint 2 or metal powder stagnated on the bottom part of a paint pan 1 is sucked from the suction port 5 provided to the bottom part of the paint pan 1 by a recirculation pump 6 through a flow passage 6a and recirculated to the tank part 1a in a recirculated paint supply side partitioned by a weir plate 4a from a pickup roll side tank part 1b through a flow passage 6b. By this method, because the paint 2 always flows under stirring, no concn. irregularity is generated and the uniformity of a paint film in the continuous painting of a strip material can be drastically enhanced.

摘要： PURPOSE:To cool uniformly the top and bottom surfaces of a high-temp. thick steel plate made by hot rolling by setting a reference value from the width of the steel plate and water flow density in accordance with a preliminary made table for the reference value and correcting the reference value by the correction value set from the thickness of the steel plate and determining said value as the shielding width by a shielding member. CONSTITUTION:The set table is made on the basis of experiment and empirical rule and the reference value is set from the width of the steel plate and water flow density. The reference value is corrected by the correction value set from the thickness of the steel plate and the corrected value is determined as the shielding width by the shielding member. The shielding width at each end in the transverse direction of the steel plate by the shielding member can be set easily in short time in the above-mentioned way without the calculation of convergence. The shielding width of the shielding plate is thus set and the hot rolled high-temp. steel plate is cooled by the cooling water flow from the top and bottom surfaces.

摘要： PURPOSE:To prevent the malshape of a steel sheet caused by a cooling strain and to improve the shape of a steel sheet after cooling by specifying the ratio of water flow rates for both sides of the sheet in cooling a hot steel sheet after hot rolling by the cooling water of prescribed average flow-rate density, from the front end of sheet to the rear end in sequence in the restrained passing direction of sheet. CONSTITUTION:A hot steel sheet rolled by hot thick-sheet finish rolling is passed along a pass line 1 in a nonstrained state. During this time, the steel sheet is directly hardened by cooling both sides of the high-temperature steel sheet from its front end to its rear end in sequence in its passing direction with the aids of cooling-water flows sprayed from respective nozzles 5', 7 through upper and lower headers 4, 6 used for hardening the sheet directly in an on-line. In this case, both sides of the sheet are cooled by regulating the cooling-water flow to an average flow-rate density of 0.7- 2.0m /sec.m , and regulating the starting temperature of cooling of the sheet to >=Ar3 transformation point and the cooling stopping temperature to >=200 deg.C. And the flow- rate ratio of cooling water (upper side flow-rate/lower side flow-rate) for both sides of steel sheet is prescribed within a range expresed by the equation. After a result, the prescribed quality of steel sheet by the direct on-line hardening is obtained.
