Precautions For Heat Treatment Of Connecting Rod By High Frequency Heating Machine

High-frequency heating machine heating products will not produce noise and dust, and will not produce waste smoke and exhaust gas, in line with national environmental protection and sustainable development guidelines, and has become the mainstream equipment in the heat treatment market in recent years. It heats up quickly, allowing the half shaft to reach the desired temperature in a very short time.

Forging process steps of connecting rod: blanking - peeling - heating - billet making and dividing - die forging - punching, trimming, thermal correction - controlled cooling of quenched and tempered or non-quenched and tempered steel - shot blasting - magnetic particle inspection - appearance Inspection - cold precision pressing - stress relief tempering - surface strengthening shot peening - straightness inspection - anti-rust packing - storage. In this process, we generally use a high-frequency quenching machine for heating, and its effect is very good. The following editor will introduce to you the matters needing attention when we use the high frequency quenching machine for heating.

1. Treatment of low/high temperature materials

Low temperature: After the billet is cooled, shot blasting needs to be reused once;

High temperature: The blank is treated as waste and enters the waste bin.

2. Temperature control (set temperature range according to the process)

Automatic control by infrared thermometer

3. Rhythm

According to the forging process

There is a certain rhythm during production, and we generally do it by adjusting the travel switch. Reason: In order to reduce the temperature difference between the two ends of the billet heating, the billet should not be exposed to the furnace mouth before the billet comes out of the furnace.

4. Control the temperature

When using a high-frequency heating machine for heating, the heating temperature is (1225 ± 25) ℃.

5. Available channels

The three channels required are: low temperature, normal temperature and high temperature, and can automatically kick the material.
