Comparison and Analysis of Common Heating Methods in Industrial Production

The current situation of many production plants is that flat plate heaters are used on-site, and the heating method transmits heat. Heating time is 5 minutes. The main consideration direction is to worry about damage to the workpiece caused by excessive heating speed.

The analysis is as follows:

Advantages: The equipment is simple and the cost is low, and multiple pieces can be preheated at a time. Easy to operate. Suitable for batch heating of small workpieces. Scenarios with no special requirements for temperature difference.

Disadvantages:

Uneven heating (heating platform temperature conduction from bottom to top, with a large temperature difference between top and bottom)

Low thermal efficiency (about 50% energy efficiency loss, insufficient energy conservation and environmental protection)

Low degree of automation (not applicable to the rhythm requirements of automated production)

The workpiece temperature cannot be detected. The actual temperature and temperature difference of the workpiece cannot be controlled. Unable to record the process according to temperature.

After market research and analysis. The standardized process for hot installed bearings and shaft sleeves uses electromagnetic induction heaters. For example, ordinary power frequency bearing heaters. Medium and high frequency induction heaters, etc. After analysis, it is as follows:

1： Ordinary power frequency induction heater

Heating bearings and shaft sleeves need to be threaded onto the transverse heating rod. Manually connect the temperature probe to the inner race of the bearing. Heating requires setting the required temperature each time. Heating completed. After manually removing the temperature measuring probe. Move the lateral heating rod. Remove the bearing for installation. The heating time is generally around 1-2 minutes.

Advantages: Suitable for manual heating installation in factories. It has good compatibility and can heat various sizes of heating needs.

Disadvantage: Not suitable for automated assembly lines.

2： Medium and high frequency induction heater

Medium and high frequency heating equipment. Suitable for heating needs in automated assembly lines, sensors are customized according to the inner diameter of the workpiece. Real time detection of workpiece temperature by infrared thermometer can be carried out in time mode, temperature mode, and power mode. It can meet different sizes and heating requirements.
