立磨是一种理想的大型粉磨设备,广泛应用于水泥、电力、冶金、化工、非金属矿等行业。立磨减速器为立磨中的关键件,如果其渗漏不但影响机器的外形美观,而且浪费油品,给设备的维修维护造成很大麻烦,而在立磨减速器中,中筒体的焊接是重点和难点。本文针对中筒体所用材质35CrMo进行焊接性分析及焊接工艺评定,制定合理的焊接工艺规程,用于指导中筒体的焊接,并取得成功。 Vertical mill is an ideal large-scale grinding equipment, widely used in cement, electricity, metallurgy, chemical industry, non-metallic mineral and other industries. Vertical mill reducer vertical mill for the key pieces, if the leakage not only affects the appearance of the machine beautiful, and waste oil, to the equipment maintenance and maintenance caused great trouble, and in the mill reducer, the cylinder Welding is the focus and difficulty. In this paper, the material used for the cylinder 35CrMo weldability analysis and assessment of welding technology, development of a reasonable welding process, used to guide the welding of the cylinder, and achieved success.
