| Abstract: | Because of demand for hot - rolling hardness for steel grade of 42CrMo series and complicated site operation flow,＂ the beginning slow - cooling temperature＂ and ＂ cooling speed＂ in production are difficult to control and operate. By multi - factors analysis of variance, the key operation steps are found out, the concrete and quantitative indexes are used to control and optimize, and the hot hardness of this kind of steel grade can meet the requirements of customers. |
