Microalloy non-quenched and tempered steel forging and cooling control technology and automatic production line

Abstract

The invention relates to a microalloy non-quenched and tempered steel forging and cooling control technology and an automatic production line, which belong to the field of metal materials processing, i.e., the forging deformation parameters and the post-forging cooling technology of the non-quenched and tempered steel are controlled, and the post-forging cooling technology is realized on a post-forging cooling control production line. The cooling production line consists of a cooling medium supply system, a power transmission mechanism, a temperature detection system, an industrial control computing system, a feed and discharge mechanism and a heat insulation system, can be manually and automatically operated according to the cooling velocity, the production cycle and the established procedure of non-quenched and tempered steel workpieces, and the ranges of the forging and cooling velocities can be adjusted. After the microalloy non-quenched and tempered steel forging and cooling control technology and the automatic production line are adopted, the phenomena of the uneven textures and performances of the non-quenched and tempered steel workpieces, the deformation and the like are eliminated, the problem of unqualified parts is solved, and the forging metallographical texture, the plasticity and ductility indicators, the production efficiency and the yield are improved.

Description

technical field [0001] The invention belongs to the field of metal material processing, relates to micro-alloy non-quenched and tempered steel controlled forging-controlled cooling technology, and also relates to non-quenched and tempered steel controlled cooling production line. Background technique [0002] The micro-alloy non-quenched and tempered steel controlled forging-controlled cooling technology and automatic production line are a core technology related to energy saving, emission reduction, stability and promotion of the production and application of non-quenched and tempered steel in my country. Quality steel is of great significance. The traditional non-quenched and tempered steel forging process is rough, and there are no strict standards for parameters such as heating temperature, holding time, initial forging temperature, and final forging temperature, which can easily lead to coarse grains and decreased toughness. In terms of cooling after forging, small-size...
