Abstract

The invention discloses an automatic cooling method and automatic cooling equipment in the process of heating large forgings. The automatic cooling equipment in the process of heating the large forgings mainly cools the large forgings through blast blowers aiming at the heat treatment of forgings such as large spindles and the like; and by measuring the temperature of the large forgings, the number and rotating speed of the blast blowers participating the cooling work are automatically controlled, and when preset time (temperature) is achieved, an automatic control system stops the work of the blast blowers and the cooling process is finished. Through the invention, the large forgings can be cooled according to a cooling curve, no deviation is ensured, and the cooling process is accurately controlled. The invention can be applied to the heat treatment cooling process of large spindle forgings, and also can be applied to the field of machining requiring accurate control of the cooling process.

Description

technical field [0001] The invention belongs to a method and equipment for automatically cooling steel materials after heating, in particular to a cooling method for heat treatment on large forgings. Background technique [0002] As we all know, many large spindle forgings have special shapes and high quality requirements. In the forging process, the heat treatment process is a very important process, and its microstructure and performance are directly related to the service life and safety of the workpiece. [0003] Heat treatment of forgings is a process of changing the inner group of steel wheels through heating, heat preservation and cooling to obtain the required properties. This process is one of the important processes in metal processing. Its purpose is to eliminate forging defects, such as coarse grains, Widmanstatten structure or banded structure, etc. due to the high or low final forging temperature during forging); and prepare the structure for subsequent proce...
