    • There is provided a method of making a welded can body having a mash seam weld which includes a heat affected zone extending continuously in the longitudinal direction thereof and is formed with no pitting. The weld is formed by mash seam welding a lapped portion of a can body preform made of a surface treated steel sheet while allowing an alternating current to flow through the lapped portion via a water-cooled elongated electrode and a water-cooled rotary electrode. The alternating current has a crest factor satisfying an expression 1.5.ltoreq.Ip/Ie.ltoreq.2.0, where Ie and Ip designate an effective value and a peak value, respectively, of the alternating current.
    • 提供了一种制造具有压薄缝焊接的焊接罐体的方法,其包括在其纵向方向上连续延伸的热影响区域,并且没有形成点蚀。 焊接是通过压薄焊接由表面处理钢板制成的罐体预制件的重叠部分,同时允许交流电流通过水冷细长电极和水冷旋转电极流过研磨部分而形成的。 交流电流具有满足1.5≤Ip/ Ie <2.0的波峰因数,其中Ie和Ip分别表示交流电的有效值和峰值。

    • A method and apparatus for guiding the opposed edges of sheet material into substantially abutting edge-to-edge relationship with one another and thereafter welding said edges by a high energy welding source to form a seam. The invention enables the continuous high speed butt welding of the sheet material to form cylindrical bodies. The apparatus includes three elements, a mandrel, a mandrel holder and tube holders. Sheet material is fed to around said mandrel and advanced by a tube holder with an edge of two opposite edges of said sheet material being in intimate contact with a basis plane of said mandrel holder. Another edges is slided into contact with above mentioned edge of sheet material making abutting relationship after passing through the basis plane of said mandrel holder. These abutting edges pass a high energy zone of a welder and butt welded to make a tube.
    • 一种用于将片材的相对边缘引导成彼此基本上邻接的边缘到边缘关系的方法和装置,然后通过高能量焊接源焊接所述边缘以形成接缝。 本发明能够使片材的连续高速对接焊接形成圆柱体。 该装置包括三个元件,心轴,心轴保持器和管座。 片材被馈送到所述心轴周围并由管保持器推进,其中所述片材的两个相对边缘的边缘与所述心轴保持器的基础平面紧密接触。 另外的边缘与上述片材的边缘滑动接触,在穿过所述心轴保持器的基面之后形成邻接关系。 这些邻接边缘通过焊机的高能区域并对接焊接以制造管。

    • A process for the production of aluminum hydroxide from an alumina-containing ore comprising, in a process for the production of aluminum hydroxide involving extraction of alumina from an alumina-containing ore by an aqueous alkaline solution, supplying a slurry containing the alumina-containing ore at a high solid content which is prepared from a small amount of an alkaline solution together with an aqueous alkaline solution which is so preheated to a temperature that a preheated temperature is enough high to have a temperature after the mixing with the slurry which is higher than an extraction temperature of alumina, simultaneously or after the mixing them, to an extraction apparatus comprising of a tube reactor, extracting alumina from the alumina-containing ore under extraction conditions of a temperature of 120.degree.-160.degree. C. and an extraction time within 10 minutes, separating dissolution residue from an extract solution immediately after the extraction, desilicating the extract solution, and adding seeds of aluminum hydroxide to the extract solution which is desilicated so as to precipitate aluminum hydroxide. By the production process, it is possible to economically produce aluminum hydroxide with little contamination by silica from the alumina-containing ore with a high content of the reactive silica.
