高硅铸铁具有十分优异的耐腐蚀性能,适用于除还原性酸以外的各种酸类介质中,目前在工业部门已得到广泛应用。但是,因高硅铸铁的硅元素含量较高,焊接可焊性较差。所以,要想获得良好的焊补质量,应根据高硅铸铁的材料特性,采取相应的焊接工艺措施。下面就将高硅铸铁的材料性能、可焊性、减应法焊补实例介绍如下。 High silicon cast iron has a very good corrosion resistance, suitable for all kinds of acid medium other than reducing acid, which has been widely used in the industrial sector. However, due to the high silicon content of high silicon cast iron, the weldability is poor. Therefore, in order to obtain a good welding quality, should be based on the material properties of high-silicon castings, take the appropriate welding process. The following will be the high-silicon cast iron material properties, weldability, welding method to reduce the case described below.
