文档介绍：软陶花的制作方法(Method of making clay flower)
The evil is happiness refers to good things change Zhuanzaiweifu into the same cand heat treatment process of basic fire, only the heating and cooling process of two of these processes hold each other, one of the important steps of heating method for intermittent heat treatment of heat treatment, the earliest production of charcoal and coal as a heat source, which should be liquid and gas fuel should be heating is easy to control, and no environmental pollution. These heat sources can direct heating, can also be through molten salt or genus, or the floating particle heating is heated, the workpiece is exposed in the air, often occurs decarburization carbon content of steel parts surface the lower parts of the surface is very good after heat treatment is usually loud and should be heated in a controlled atmosphere or protective atmosphere vacuum, can also paint or packaging. One of the important parameters for the protection of heating temperature of heat treatment process, selection and control of heating temperature, to ensure the quality of heat treatment to the heating temperature of metal materials and heat treatment with different treatment, but generally heated to above the phase transition temperature to obtain tissue in need of another change will take some time, this is the surface of the workpiece to reach the heating temperatur
