摘要： A process for producing a thin-webbed H-beam steel having a web thinner than flanges, which comprises the steps of: forcibly water cooling the outer surface of the flanges during an intermediate hot rolling prior to a final hot rolling, so that the flange outer surfaces are cooled to a temperature of 700 DEG C or lower; terminating the forcible water cooling during the intermediate hot rolling so that the flange outer surfaces are returned to a temperature higher than 700 DEG C; repeating the forcible water cooling and the termination thereof during the intermediate hot rolling to refine the microstructure of the flange surface to a predetermined depth from the surface; final-hot rolling the intermediate-hot rolled H-beam steel; and forcibly water cooling the flanges of the final-hot rolled H-beam steel immediately after the completion of the hot rolling, in a manner such that either the cooling time is not longer than an upper limit or the difference between the flange and the web temperatures upon completion of the cooling is not less than a lower limit, within which upper and lower limits the wavy web does not occur during the cooling, and such that either the cooling time is not less than a lower limit or the difference between the flange and the web temperatures upon completion of the cooling is not more than an upper limit, within which lower and upper limits a thermal stress, generated in the web during air cooling to room temperature, does not exceed a buckling strength of the web, the upper and lower limits being predetermined with respect to the size of H-beam and the density of the coolant water quantity. An apparatus for carrying out the process is also disclosed.

摘要： PURPOSE:To enable straightening of a plate from thin one to thick one with one kind of straightening rolls by shifting an upper frame and a lower frame assembling plural straightening rolls and backup rolls as liftable for each to line direction. CONSTITUTION:At the time of straightening the thin material, the backup roll stands are shifted outward to right and left directions with a shift cylinder 5 so that roll surfaces of all straightening rolls face to surface position. By this method, all straightening rolls can be used to the material to be straightened. Further, at the time of straightening the thick material, the backup roll stands are shifted to inward to right and left directions with the shift cylinder 5 so that the straightening roll vertically lifts/lowers to each one piece. By this method, the straightening rolls alternately becomes to recessing and projecting conditions and the straightening rolls are alternately worked as the straightening rolls to the material to be straightened and the other non- working rolls do not contact with the material to be straightened, and even the material having wide roll pitch and thick material can be straightened.

摘要： PURPOSE:To make the impact soft force when the shapes contacts and collides with the vertical roller and to prevent the device from being damaged by arranging the swing-moving center of the other end side of lever from the rotary center of vertical roller of one side of lever to the shapes side. CONSTITUTION:One end of the levers 4, 4A are set at the rotation center 6, 6A positions of the vertical rollers 5, 5A, and the other end is made to the swing-moving centers 3, 3A, and the swing-moving centers are arranged from the center of the vertical roller to the shape 1 side. Therefore, by swinging the levers 4, 4A against the load of both directions of the shape carrying direction, the interval between the cooling nozzle and the flange surface of the shape 1 is kept constant, and at the same time, the impact force when the shape 1 contacts and collides with the vertical rollers 5, 5A is relieved.

摘要： PURPOSE:To eliminate the air stagnation in the liquid supplying pipe of a nozzle header, etc., and to eliminate the delay of response of the injecting pressure from the nozzle caused on its air stagnation by connecting the replenishing liquid supply pipe to the nozzle header separately from the liquid supply pipe. CONSTITUTION:The water quantity equivalent to the water quantity of the cooling water streamed out from the nozzle 1, that is, the little quantity of the water without generating the water lack against the nozzle is supplied from the replenishing water supply piping 23. Therefore, the air clearance can be prevented from generating in the cooling water supply piping, especially in the nozzle header 2 set with plural pieces of nozzle 1.

摘要： PURPOSE:To provide a controlling method for a clutch of a bridle by which relative slip of the surface of a roll and the surface of a metallic belt like sheet is prevented when one of a steel belt, galvanized steel belt or stainless steel belt, etc., is passed to an intermediate bridle. CONSTITUTION:On each of upstream and downstream sides of a pass line for the metallic belt like sheet S, each of incoming and outgoing side bridles 4 and 5 is respectively provided and an intermediate bridle 1 arranged between the bridles 4 and 5 consists of a roll line of three or more rolls. The diameters of three rolls are arranged like larger - smaller - larger or smaller - larger - smaller from upstream to downstream of the sheet S. The direction of torque applied on the bridle 1 is judged from power of a main driving motor 6 by which the bridle 1 is driven, an incoming side elongation percentage controlling motor 7 and an outgoing side elongation percentage controlling motor 8 and the clutch 17 is attached and detached so as the larger diameter roll is always arranged on one side of the sheet S on which high tensile force is applied.

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.
