    摘要： A lubricant is supplied from headers (38) of lubricant supply units (5) onto surfaces of back-up rolls (3) at locations spaced from contact positions between a pair of work rolls (2) and a pair of back-up rolls (3). The headers (38) each include a lubricant spray nozzle (41) for spraying the lubricant under a pressure not lower than 3 kg/cm², a header cover (42) for confining the lubricant sprayed from the lubricant spray nozzle (41), an oil return line (44) for returning the surplus lubricant, and seal members (43) made of flexible material such as rubber. The work rolls (2) are provided with water wiping plates (6), and the back-up rolls (3) are also provided with water wiping plates (7). 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 (2) and the back-up rolls (3). Raw lubricant oil of the lubricant meets the following requirements; (a) the coefficient of friction between said work rolls (2) and said back-up rolls (3) is in the range of 0.04 to 0.1, (b) the viscosity is not larger than 80 Cst. at 40 °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 rolling mill has a housing (42), an upper work roll (43A) and a lower work roll (43B) adapted to cooperate in rolling a material therebetween, supporting rolls (46) disposed at the upper and lower sides of the upper and lower work rolls such as to vertically support and drive the work rolls, horizontal supporting rolls (49) disposed at a lateral side of the work rolls so as to support the work rolls from the lateral side in the direction of travel of the rolled material, and horizontal back-up rolls (48) disposed at a lateral side of the horizontal supporting rolls so as to back-up the horizontal supporting rolls The rolling mill further has a holding means (54) for rotatably holding the horizontal supporting rolls and the horizontal back-up rolls at both axial ends of these rolls, a first driving means (64) provided on the housing and mechanically connected to the holding means, the first driving means (64) being adapted to cause a movement of the holding means in the direction of travel of the material to be rolled and to impart to the work rolls desired pressing force acting in the direction of travel of the rolled material, a second driving means (66) provided on the housing and adapted to engage with a restraining means (66B) for restraining the position of the holding means such as to move the holding means (54) through the restraining means thus setting the work rolls at predetermined offset positions, and a guide means (58) provided on the face of the housing confronting the holding means and adapted to guide the movement of the holding member in the direction of travel of the rolled material. With this arrangement, it is possible to prevent any horizontal deflection of the work roll thus affording a highly precise crown and shape control on the rolled product, while facilitating the setting of the work rolls at a designated offset position, as well as replacement of the work rolls.

    摘要： A rolling mill for rolling metal strip (11) moving in a horizontal rolling direction, has work rolls (1) which engage the strip and are supported vertically by backup rolls (2) through which drive is applied. The work rolls (1) are supported in the horizontal rolling direction by support rollers (4) contacting them at locations confined to intermediate regions between the work regions and bearings (8). The work rolls are shiftable in the horizontal rolling direction. To provide control of the horizontal forces during rolling, there are position control means (5,7) for the support rollers operable to move and locate the support rollers so as to shift the work rolls (1) to a predetermined location at which the vertical axial plane of the work rolls (1) is offset in the horizontal rolling direction from the vertical axial plane of the backup rolls (2). The support rollers (4) maintain the work rolls at the predetermined location during rolling.
