Medium frequency steel bar quenching furnace needs periodic quenching parameter verification

Medium frequency steel bar quenching furnace needs periodic quenching parameter verification

Quenching is a heat treatment process of heating the metal workpiece to its critical temperature by rapid cooling to obtain martensite based unbalanced tissue. Quenching is more widely used in heat treatment process. Metal workpiece can greatly improve its rigidity, wear resistance, hardness, fatigue strength and toughness, so that metal workpiece can meet the requirements of different applications.

We know that steel bar quenching furnace needs regular maintenance. Besides regular maintenance and repair, what do we need to do for heat treatment steel bar quenching furnace? As the saying goes: a small discrepancy leads to a great error. It is the same for the induction quenching process. Because the quenching effect is influenced by many factors, it is necessary to verify the quenching parameters of the heat treatment steel bar quenching furnace so as not to affect the effect of the quenching of the workpiece.

1. Why do steel bar quenching furnace quenching parameters need periodic verification?

As the current electric furnace adopts indirect parameters such as current, voltage, output power and relative moving speed, the thermal parameters (heating temperature and time) are controlled by the current heat treatment electric furnace, so the stability of various parameters of the steel bar quenching furnace has a great influence on the quality of the workpiece quenching. Therefore, the induction heat treatment furnace needs regular parameter verification.

2. Under what circumstances, steel bar quenching furnace needs parameter verification?

A. After repairing or replacing electrical components for the steel bar quenching furnace (including quenching inductor), the quenching process parameters need to be re verified.

B. In the normal production process, we must regularly verify the original quenching process parameters to ensure the long-term effectiveness and controllability of the production process.
