一、产品及工艺过程简介图1是经过改进后的双层金属堵塞产品图。这种堵塞装在柴油机气缸盖上,解决了单层金属(表面镀镉的钢)堵塞因长期受水浸蚀而烂穿的问题,采用双金属堵头的好处是:与水接触的表层采用厚度较薄、耐腐蚀性好的材料(H62),而内层是一般的拉伸钢。同时,这种结构比采用单层有色金属、不锈钢及金属复合材料具有良好的经济效果,设双金属堵塞的材料费为1,那末黄铜堵塞的材料费即为2,不锈钢堵塞的材料费即4.8。
First, the product and process profile Figure 1 is an improved double-metal block product map. This plug is mounted on the cylinder head of a diesel engine and solves the problem of single-layer metal (cadmium-plated steel) plugging due to long-term water erosion and wear. The advantage of using bimetal plug is that the surface in contact with water Thinner, corrosion-resistant material (H62), while the inner layer is generally drawn steel. At the same time, this structure than the use of single-layer non-ferrous metals, stainless steel and metal composite material has a good economic effect, set bimetal plug material cost is 1, then the brass plugging material cost is 2, stainless steel plugging material cost 4.8.
