Introduction of high chromium high manganese steel composite casting hammer
Guide:Introduction of chrome high manganese steel composite casting hammer head, hammerhead high chromium cast iron, hammer handle high manganese steel (or ZG35) two kinds of metal liquid poured into the hammer and hammer handle parts, the lost foam casting process is better than the sand type process. At present, there are not many such processes, and it is necessary to have two induction furnaces to smelt high-chromium cast iron, cast steel (high-manganese steel), and a lost foam casting process.
High-chromium cast iron liquid and high-manganese steel (cast steel) liquid have their own characteristics, which can not be confused into one, but also make the hammer head handle clarified and firmly combined. It is necessary to ensure the orthogonality of solidification, shrinkage and cooling of the two processes. Point, obtain a high-quality composite casting hammer, for example, in order not to mix the two, in the high chromium cast iron (hammer head) gate into the white mold, add Q235A structural steel to adjust the control. The production of composite cast high-chromium cast iron and cast steel or high-manganese steel hammers must be determined from the actual situation of the unit and after the process test.
The red apple casting reminds us to strictly control the lost foam casting process rules, and to maximize the control of the gas and slag (gas, liquid, solid) generated by the white mold combustion, so as not to cause adverse consequences in the hammer cavity, such as air entrainment, Porosity, slag inclusions, etc. The process of compound casting hammer, casting process requirements, and lost foam process specifications, only the specific practice of this unit, continuous improvement and improvement, in order to obtain high quality recast hammer.
