摘要： PURPOSE:To improve rigidity and to produce an embossed plate having a reduced weight and formability in combination by forming the shoulder parts of the recessing and projecting grooves of male and female rolls in a way as to have the prescribed radius of curvature and determining the overall thickness of the embossed plate after embossing at the specific times of the thickness of an original plate. CONSTITUTION:A metallic plate 3 is embossed by a pair of upper and lower male and female rolls 1 and 2. The radius R of curvature in the shoulder parts of the grooves of the rolls 1 and 2 is set at >=0.2 times the thickness (t) of the original plate. The thickness T over the entire part of the embossed plate is made to 1.5-2.5 times the thickness (t) of the original plate. The embossed plate having a beautiful appearance and having high rigidity and while maintaining good formability is thus obtd.

摘要： PURPOSE:To improve the descaling efficiency and the working efficiency, by determining the tensile stress to be impressed on the rod to be descaled according to the peculiar formula, and by deciding various dimensions like as the roll diameter, etc., correspondingly to thus determined stress. CONSTITUTION:The tensile stress sigmaT to be impressed on the rod 1 is determined according to the formula I depending on the yield point sigmaY and Young's modulus E of the descaled rod 1, and the elongation (e) to be given to the descaled rod 1 and the number (n) of the rolls. Correspondingly to this tensile stress sigmaT, various dimensions like as the roll diameter, the pitch, the rolling reduction, etc., of the roll bender are decided. The set tension T0 is calculated (calculation from the elongation and rod diameter) from the stress sigmaT, and this value T0 as the set value is inputted to the controller 5. The controller 5 sends the control signal corresponding to difference between the measured tension T and the set tension T0, to the motor 6; in case of T0>T, the roll 2 is shifted in the arrowed direction under the specified rolling reduction, and in case of T0

摘要： PURPOSE:To give a specified elongation to the rod, and to make possible the setting of roll bender for obtaining the most favorable descaling effect, by obtaining the rolling reduction or the pitch suitable for each roll through the specified formula and the experimental graph, in the discaling apparatus of the roll bender for the rod. CONSTITUTION:In case of descaling of the rod 1 through the roll 3 group, at first the rod diameter D and the pitch P are determined by the geometrically obtained formula I (where alpha is the apparent contact angle shown by the roll 7, D is the roll diameter, H is the rolling reduction, P is the roll pitch, which is 1/2d for the entry and the exit rolls), and the formula II (where thetaN in the equivalent contact angle for roll down to the N-th roll, N is the number of rolls, i shows the i-th roll); the contact angle thetaN is obtained from the separately specified experimental formula, H is assumed, and alpha ia obtained from the formula I; this alpha is substituted into the formula II for obtaining thetaN; and then, the rolling reduction H is calculated by the trial and error method. When the pitch P is made variable and H is made constant, the pitch P is obtained; by this pitch P, the necessary minimum elongation (5-10%) is given to the rod 1, and the setting of the roll bender for obtaining the greatest descaling effect can be carried out.
