摘要： PURPOSE:To contrive reduction of the distance between the vertical roll and the horizontal roll, by partly overlapping respective housing of adjoining vertical and horizontal rolling mill stands in the same vertical plane, and by tying these overlapped part with the tie-bolt so as to integrate two housings into one body. CONSTITUTION:The vertical roll assembly comprising the vertical roll 1 and the chock 2 is set in the vertical rolling stand whose upper and lower housings 3, 4 are being splitted by the split planes 5, 5'. On the other hand, the horizontal roll assembly comprising the horizontal roll 6 and the chock 7 is set in the horizontal rolling stand whose housing 8 makes the opening being cut at planes 9, 10, on the side facing to housings 3, 4. Respective parts 11, 12 of housings 3, 4 are inserted as one body into above stated opening; hereby, the plane 9 with the part 11, and the plane 10 with the part 12, are respectively combined so as to make mutual contact. The housing 8 is tied to parts 11, 12 with the tie-bolt 13. As a result, the housing 8 is united with housings 3, 4 through the planes 5', 9 and 10.

摘要： PURPOSE:To eliminate mis-matching in processes of casting and rolling and enhance the overall efficiency of both processes by such things as cutting the bloom of a fixed width produced in a continuous casting unit to the length limited by the width of a recuperation furnace, loading the blooms into the recuperation furnace while their surfaces are still at the specific temperature to recuperate the same then broadside-rolling the same through plural passes. CONSTITUTION:The bloom of a fixed width produced in a continuous casting process A is cut to a length of 70 to 100% of the effective width of a recuperation furnace 2. While the surface temperature of the blooms are still at above 850 deg.C, the cut blooms are subsequently loaded into the recuperation furnace 2 through conveying table 1 whereby they are recuperated. Next, the blooms are taken out onto a conveying table 3, from where they are subjected to broadside rolling in the vertical rolling mill 4-1 and horizontal rolling mill 4-2 of the broadside rolling mill 4, thence they are supplied to the rolling process B. According to this method, the point that the processes of continuous casting and rolling do not match at all while being operated under respectively finest conditions is eliminated during conveying of the blooms between both processes.

摘要： PURPOSE:To recover the sensible heat and latent heat of an ingot efficiently by conducting the liquid refrigerant used for cooling the ingot to a heat exchanger, and gasifying the low b.p. gas in this heat exchanger thereby revolving a turbine. CONSTITUTION:A liquid refrigerant is supplied to ingot cooling members 2 to cool an ingot S. This discharged refrigerant is again supplied to the cooling members through a heat exchanger 3. This exchanger 3 is used as an evaporating part, and a low b.p. gas turbine 5, a liquefier 6, and a force feed pump 7 are communicated and connected successively thereto between the outlet side thereof to the inlet side. A low b.p. gaseous ''Fron '' which is liquefied is introduced into the heat exchanger 3 by which it is liquefied and this is supplied and discharged to and from the turbine 5, then the liquefied gas is cyclically supplied from the pump 7 again to the exchanger 3 through a liquefying device 6. The gas turbine is run continuously at a high speed by this, whereby electric power is generated and the recovering energy of the ingot 3 is converted and recovered efficiently.

摘要： PURPOSE:The captioned position adjusting device which is improved of its workability with a simple mechanism by moving and adjusting roll assemblies by the liquid pressure cylinder devices fixedly mounted to the yokes constituting the slide parts supporting said assemblies. CONSTITUTION:A vertical roll 5 having a caliber 4 constitutes a roll assembly 3 together with a pair of chocks 6, 6 supporting this and this assembly 3 is assembled and supported slidably in the roll axis direction to a yoke 7. A liquid pressure cylinder device 14 is fixedly mounted to the yoke 7 and said yoke 7 is made adjustable of its roll radial direction position by a screw-down mechanism 10. The position of the piston 15 of the liquid pressure cylinder device 14 is detected by a position detector 18 and pressure fluid is fed into the cylinder 17 or 17' through the control system of the liquid pressure cylinder device, whereby the roll assembly 3 is vertically adjusted. Thereby, the relative position of the roll caliber 4 with respective to the horizontal table 2 is adjusted most adequately.
