    摘要： A gage control system for a rolling mill for compensating for variation in the thickness of rolled material due to variations in the rolling load or pressure. In the system, the roll eccentricity frequency produced by the eccentricity of the rolls is detected and utilized for softening the effective rigidity or stiffness of the mill, that is, weakening the apparent mill modulus by control means according to the frequency of roll eccentricity. To this end, a positive feed back path including an eccentricity control unit is provided in parallel with a feed back path of the rolling pressure signal of a gage control circuitry of the so-called BISRA system. The eccentricity control unit serves to detect the roll eccentricity on the basis of a correlation principle and compensate for or cancel the effects of the feed back of the rolling pressure upon the occurrence of the roll eccentricity.

    摘要： A lubricant is supplied from headers of lubricant supply units onto surfaces of back-up rolls at locations spaced from contact positions between a pair of work rolls and a pair of back-up rolls. The headers each include a lubricant spray nozzle for spraying the lubricant under a pressure not lower than 3 kg/cm.sup.2, a header cover for confining the lubricant sprayed from the lubricant spray nozzle, an oil return line for returning the surplus lubricant, and seal members made of flexible material such as rubber. The work rolls are provided with water wiping plates, and the back-up rolls are also provided with water wiping plates. In a work rolls crossing type mill thus arranged, water films of cooling water deposited on the roll surfaces are removed to prevent the cooling water from mixing into the lubricant. Even if the water films are not totally removed, it is possible to surely plate out the lubricant for reliably lubricating between the work rolls and the back-up rolls. Raw lubricant oil of the lubricant meets the following requirements; (a) the coefficient of friction between said work rolls and said back-up rolls is in the range of 0.04 to 0.1, (b) the viscosity is not larger than 80 Cst. at 40.degree. C., (c) mineral oil and synthetic ester not less than 5% are contained as base oil, (d) a fatty acid in the range of 0.03 to 0.5% is contained as an oiliness enhancer, (e) an extreme pressure additive not less than 0.1% is contained, and preferably, (f) a surface active agent not larger than 0.5% is contained as emulsifier.

    摘要： A trailing end of a preceding bar is arranged slantingly by an angle .theta. relative to a succeeding bar such that the lower edge of the leading end face of the succeeding bar is vertically shifted from the lower edge of the trailing end face of the preceding bar with the leading end face of the succeeding bar abutting against the trailing end face of the preceding bar. After that, the succeeding bar is vertically depressed by applying a predetermined force. Since the trailing end face is inclined by .theta. relative to the leading end face, the depression causes a relative slide between surfaces of both the end faces and, at the same time, a pressure P is also produced by the wedge effect, the pressure P causing a compression force and a plastic deformation between both the end faces. Oxide scales on the contact surfaces of both the end faces are peeled off due to the plastic deformation and the relative slide, so that the metal surfaces of the material are exposed to join the bars simultaneously in combination with the compression force and the plastic deformation caused by the pressure P. Thus, the bars are joined to each other in a short time for realization of continuous hot rolling.
