摘要： A work roll cross type rolling mill comprises a pair of work rolls and a pair of back-up rolls for backing up the work rolls. The back-up rolls are so arranged that their axes can be inclined within horizontal planes only to three or four specific angular positions. The work rolls are allowed to be inclined within horizontal planes with respect to the back-up rolls such that the axes of the work rolls cross the axes of the associated back-up rolls and cross each other. The nip between each the work roll and the associated back-up roll is lubricated so as to reduce axial thrust generated therebetween due to the crossing of the rolls. The cross angle between the work rolls is set and controlled during rolling operation only when the roll peripheral speed or the rolling speed is 50 m/min or higher. Advantages of work roll cross type rolling mill are fully extended to realize stable rolling without trouble so as to ensure high quality of the rolled product while achieving higher rate of operation of the mill with facilitated operation.
摘要翻译：工作辊十字型轧机包括一对工作辊和一对支承工作辊的支承辊。支撑辊的布置使得它们的轴线可以在水平面内仅倾斜到三个或四个特定的角度位置。允许工作辊相对于支撑辊在水平面内倾斜，使得工作辊的轴线与相关的后备辊的轴线交叉并彼此交叉。每个工作辊和相关的支撑辊之间的辊隙被润滑，以便减少由于辊的交叉而在其间产生的轴向推力。只有当辊圆周速度或轧制速度为50m / min以上时，轧制操作之间的工作辊之间的交叉角度被设定和控制。轧辊交叉式轧机的优点得到充分发挥，无故障地实现了稳定的轧制，从而确保轧制产品的高质量，同时在操作方便的同时达到更高的轧机运行速度。

摘要： A five-high rolling mill is disclosed which includes an upper work roll backed by an intermediate roll and a backup roll and a lower work roll backed up by a single backup roll. Control benders are provided on each of the intermediate roll and the upper and lower work rolls. In order to optimize the control of the rolling operation for skinpass rolling and the like, the control benders for the upper work roll and the intermediate backup roll are controlled so as to effect a control of the crown sheet over the entire width of the material being rolled, while the control bender for the lower work roll controls the sheet crown of the rolled material at the lateral side end portions, resulting in a composite control substantially improving the sheet quality and preventing edge wrinkles in the material being rolled. In the disclosure embodiments, the intermediate roll has a larger drum length than a predetermined maximum sheet width of rolled material to be rolled by the work roll.

摘要： A high speed pickling device for causing a thin plate to travel in acid fluid and removing through pickling oxidized scales which are formed on the surfaces of the thin plate, a plurality of weir members which dam wakes of the acid fluid flowing along the surfaces of the thin plate over substantially the entire width of the thin plate are provided in the traveling direction of the thin plate with a predetermined interval and close to the thin plate.The weir members are provided close to the surfaces of the thin plate for damming and stripping off wakes of the acid fluid flowing along the surface of the thin plate at the inlet sides of these weir members, the acid fluid is caused to deflect in the opposite direction away from the thin plate, and fresh acid fluid is sucked onto its surface at the outlet sides of the weir members along with the traveling of the thin plate.According to the present invention indicated above, by providing the weir members close to the thin plate, wakes of the acid fluid which flows along the thin plate is dammed and the most part thereof is stripped off from the thin plate. This stripped acid fluid flows in an opposite direction away from the thin plate and is drained along the weir members. The remaining wakes which were not stripped off by the weir members pass through a narrow clearance between the thin plate and the weir members and proceeds to the outlet sides of the weir members in the form of thin layered wakes. At the outlet sides of the weir members thickness of the wakes along the thin plate again tends to increase and fresh acid fluid is sucked to increase the wake thickness. By these draining and sucking of the acid fluid, replacement of the acid fluid is surely performed and pickling effect is enhanced and the pickling time is shortened.

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： In a continuous hot rolling system, at least one melt-cut torch is set in a predetermined positional relationship with respect to a trailing end of a preceding hot material and a leading end of an adjacent succeeding hot material. An injected flow of cutting gas from the melt-cut torch is blown against a portion of at least one of the trailing end of the preceding material and the leading end of the succeeding material to melt-cut the portion. The portion extends from an end surface of the one end over a predetermined length. The trailing end of the preceding material and the leading end of the succeeding material are forced against each other and are butt-joined to each other. By doing so, there are produced joining surfaces superior in surface accuracy and high in temperature, to allow joining to be high in accuracy and strength. This joining may be made with respect to slabs before rough rolling, or may be made with respect to bars after rough rolling. Further, a slab manufactured by a continuous casting machine are reduced in thickness at a plurality of desired locations to form a plurality of thickness-reduced portions. Cutting is made at the thickness-reduced portions. The cut thickness-reduced portions are joined to each other. Furthermore, the ends of the respective materials after having been cut are reduced in thickness with the ends abutted against each other to form thickness-reduced portions. The thickness-reduced portions are joined to each other.
