The major activity elements of steel cast parts heat treatment:
The heat treating steel casting parts is consisting of warming, insulation and cooling three stages. A determination of its parameters, are to be sure products quality and cost as a basis. Warming is a largest consumption of energy in heat treatment activity. A major modern technology of warming activity is to purchase a appropriate warming approach, warming rate and loading mode.
(1) A warming approach of steel casting parts have radiant warming, bath warming and induction warming. A choosing concept of warming is high-speed and uniform, quick to handle and effective low cost. General should think of a length and width of a steel casting parts system, chemical composition, heat treatment activity and quality requirements.
(2) A warming rate of steel casting parts: For tiny and medium steel casting parts, you are able to not limit a warming rate, usage maximal power warming stove. Thermal furnace installed furnace are able to significantly reduce a warming time and a production cycle. Indeed under a environments of high-speed warming, surface of steel casting parts and a heart was no significant between a departments of a temperature hysteresis. And slow warming could result in lower production efficiency; energy consumption increases and causes serious casting surface oxidation and decarburization.
