我厂铸造的大型铸件,重量自一吨至十吨不等,构造比较复杂,断面厚度相差也相当大,有时往往因一些小的裂纹或砂眼等,严重的影响了铸件质量,特别是在摩擦部件的滑动表面上,更易遇到这些情况。因此如何将大铸件在不影响质量的原则下将缺陷加以适当修补回用,成为我厂铸造生产中一个亟待解决的问题。 Casting large castings, weighing from a ton to ten tons, the structure is more complex, section thickness is quite large, sometimes due to some small cracks or trachoma, etc., has a serious impact on the quality of castings, especially in the friction Parts of the sliding surface, more likely to encounter these situations. Therefore, how to make the large castings properly repair and reuse the defects without affecting the quality has become an urgent problem to be solved in the casting production of our factory.
