摘要： A method of X-H rolling of a parallel flange steel structural shape or beam with an H cross section using a compact rolling group. In the first universal mill frame the vertical roll have roll surfaces inclined to one another at an angle up to 10° whereas in the second universal mill frame the vertical rolls have cylindrical roll surfaces which divide the H opening cross section with lateral surfaces of the horizontal roll. The structural shape is rolled in the second universal mill frame to up to 100% of the reduction in the first rolling mill frame.

摘要： PURPOSE:To make roll chance free rolling and crown control rolling compatible by flattening the central part of the roll body of work rolls, forming convergent tapers toward the body ends on both sides, and moving the rolls in an axial direction. CONSTITUTION:A pair of upper and lower trapezoidal rolls each having a flat central part of the roll body and convergent parts tapered toward body ends on both sides are used as work rolls 6 in a hot finishing mill. The rolls 6 are axially shifted to a prescribed convergent length value in accordance with a fluctuation in the width of a material 7 to be rolled if said width fluctuates. The rolls 6 are shifted in the stage of rolling at the same width to make the roll wear uniform in a width direction without decreasing crown controllability. Roll chance free rolling and crown control are made compatible by the above- mentioned method.

摘要： PURPOSE: To prevent work rolls from generating partial wear by swinging periodically a strip in its width direction at the inlet side of a tandem mill.
CONSTITUTION: Strips unwound from pay-off reels 2, 2' are connected to each other by using a shear 3 and a welder 4. Next, the strip 1 after passing through a tension bridle 5 and a looper 7, is swung slowly and periodically in the width direction by a strip swinging device 11. Thereafter, the strip 1 is cold rolled by a tandem mill 15 after passing through a tension bridle 14, and is cut into the prescribed dimension by a rotary shear 16 to wind it up by tension reels 18, 18'.

摘要： PURPOSE:To provide prescribed shape corrections to both rolling materials by separating strips from each other to the upper and lower sides of a mill and passing one strip between two rolls located at the upper side and the other one between two rolls located at the lower side, at the same time, and rolling each strip by one side half of the length of each roll surface. CONSTITUTION:Strips 12, 13 obtained by dividing a wide strip are separated from each other to the upper and lower sides of a rolling mill, and the strip 12 is passed between an intermediate roll 23 and a work roll 25 located at the upper side and the strip 13 is simultaneously passed between a work roll 26 and an intermediate roll 24 located at the lower side, to roll each strip by using one side half of the length of each roll surface. At this time, an operating side and a driving side of an intermediate roll bender Pi and a work roll bender Pw are controlled separately, to control the pressure distribution A-B of the strip 12 as shown by (a)-(b) in the figure, and the edge forms of the strips 12, 13 are controlled in a wide range by moving for adjustment the rolls 23, 24 in their axial directions. Further, the strips of the upper and lower sides are replaced with each other to cope with the wear of rolls. In this way, the shape of strip is independently corrected to form the excellent edge drops at the ends of strip respectively.

摘要： PURPOSE:To prevent the breakage of roll and to improve the accuracy of sheet thickness by computing a roll gap at the time when the tail end of a rolling stock runs out of rolls, based on the sheet thickness, the roll gap and the thermal expansion of roll, etc. and spreading the roll gap based on the computed value. CONSTITUTION:A roll-diam. prediction device 1 predicts the change of roll diam., due to the amount of thermal expansion of roll and its wear, etc. after its zero adjustment, by a prescribed equation, based on the sheet thickness of outlet side outputted from a sheet-thickness meter 15 and the roll gap from a rolling reduction device 8. When the tail end of a rolling stock 13 is detected by a stock-position detector 11, a computer 3 discriminates the roll contact at that time by using a roll-diam. prediction value 2 outputted from the device 1 and the roll gap of an automatic rolling-reduction-positioning device 5. When the spreading of roll gap is required, the computer spreads it by a required quantity. In this way, the roll breakage is surely prevented and the sheet- thickness accuracy is improved.

摘要： PURPOSE:To decrease the fluctuation in the difference in the surface roughness between upper and lower work rolls and to match the timing for changing the rolls by making the abrasion resistance on the surface of the small diameter work roll higher than the abrasion resistance on the surface of the large diameter work roll. CONSTITUTION:The surface roughness of a large diameter lower work roll 3 is made larger than the surface roughness of a small diameter upper work roll 2, and the camber at the preceding end of a rolled material 1 is prevented. The abrasion resistance on the surface of the roll 2 that wears faster is made higher than the surface of the roll 3 by selecting the material and hardness of the rolls in such rolling mill with dissimilar diameter rolls, so that the abrasion wear between both upper and lower work rolls is made equal. The lubricity, etc. of the work rolls are made stable over a long period of time by such mechanism and the rolling is accomplished without generation of the camber at the preceding end, etc.
