Four factors affecting the heat treatment of high-strength fasteners

Many manufacturers, after producing fasteners, in order to ensure the quality and reliability of high-strength fasteners, heat treatment processes for high-strength fasteners, but there are many factors that affect the heat treatment process of high-strength fasteners There are four main types of effects:

1. Participants

Quality control is process control, which can be done not only by a few people or a few departments. Therefore, the following points must be done:

(1) Clarify the responsibilities and authorities of all types of personnel, and stipulate that employees must bear the responsibility of solving problems when exercising their rights.

(2) It is necessary to organize job training in a planned way, and carry out qualification certification for important positions, so as to improve personnel's operational skills and quality control skills. (Guide: Knowledge of Fasteners: Knowledge of Flange Nuts)

Two, equipment tooling

(1) There are many types of production equipment and tooling for heat treatment of high-strength fasteners, and some measuring instruments are sometimes used. Therefore, operators are required to strictly abide by the operating procedures of equipment, tooling and measuring tools, operate in a civilized manner, and perform correct and reasonable maintenance.

(2) Maintenance personnel of high-strength fastener heat treatment equipment should do a good job in daily maintenance and regular maintenance of the equipment, and perform improved maintenance on the equipment in a timely manner.

(3) Strictly implement the management system of tooling, workstations and instruments, strictly implement the management system of measurement, and do the calibration, maintenance and appraisal of measurement instruments in accordance with regulations.

Three, fastener materials

Due to the heat treatment production process, after the materials are processed, transported, and counted, due to some factors, there may be mixing, wrong material, loss, rust, bumps, and deformation, which affect the strength of the fastener material . Therefore, we must pay special attention to this aspect, be careful and careful when working, and do a good job of inspection, labeling and storage of materials.

In addition, in the heat treatment production, if problems are found in high-strength fastener materials, as long as they are repaired in time through the corresponding process technology, they can still be solved well.

Fourth, process specifications

The theory and practice of heat treatment production technology are very strong, so there must be a set of suitable heat treatment process and relatively complete operating specifications, so that the quality of heat treatment can be well controlled. The formulation of the heat treatment process should select the appropriate process parameters according to the specific high-strength fastener materials and related equipment tooling and the operating skills of the employees. This requires the heat treatment process personnel to be familiar with the production site and continue to confirm the perfect process through practice. And to continue to improve.
