| description | The invention discloses a manufacturing method for a non-quenched and tempered steel flange plate. The manufacturing method comprises the following steps that firstly, non-quenched and tempered steel bars are blanked; the bar is heated to 1150 DEG C to 1250 DEG C and then forged and pressed in a die to form a steel forge piece blank, and the final forging temperature is controlled to be 900 DEG C to 1000 DEG C; 3, controlled cooling is conducted, specifically, the steel forge piece blank in the step 2 is placed into cooling equipment, and cooling is conducted according to the heat treatment technology of the non-quenched and tempered steel through the waste heat after forging of the steel forge piece blank; the temperature entering the controlled cooling area is not lower than 850 DEG C; and fourthly, the steel forging blank cooled in the third step is machined, and the non-quenched and tempered steel flange plate is obtained. According to the method, after-forging waste heat of the workpiece is used for cool |
