YZM系列圆柱面支座是一种新型铁路桥梁钢支座,采用消失模铸造工艺生产铁路桥梁钢支座有许多优点。介绍了模样燃烧消失空型壳消失模铸造的工艺过程,研究了燃烧除碳法的模样材料性质、涂料、真空负压等主要因素的影响。实践证明这种工艺方法可有效地解决铸钢件的增碳缺陷问题。
YZM series cylindrical bearing is a new type of railway bridge steel bearing. The production of railway bridge steel bearing by the process of lost foam casting has many advantages. The article introduces the process of lost foam casting with lost foam casting, and investigates the influence of the main factors such as the material properties of the combustion carbon removal method, paint and vacuum negative pressure. Practice has proved that this process can effectively solve the carbon steel casting defects.
