iron and steel heat treatment furnace with high efficiency and high reliability

The temperature closed-loop control system of the steel bar forging through heating electric furnace uses an infrared thermometer to measure the heating temperature of the induction furnace outlet billet, monitoring whether there is overheating or incomplete heating. After temperature monitoring, the signal is always fed back to the control system of the remote variable frequency power supply, which is the working host of induction heating. The power supply automatically recognizes according to the set process requirements. When the temperature of the billet exceeds the target temperature range, the control system will automatically adjust the output power based on the set value, correct the power supply power, and control the billet temperature within the target range. Reduced the generation of non-conforming products and ensured consistency in product quality. Traditional power supply and temperature closed-loop systems do not participate in the power control of the power supply after the temperature control signal feedback, so it is impossible to correct the temperature deviation of the billet. The power supply cannot achieve automatic matching, and can only manually adjust the power/temperature or use the temperature signal for high/low temperature selection

The characteristics of steel bar forging hot electric furnace:
1. Less oxidation and decarburization during the heating process of steel bars: Due to the heat generated inside the heated workpiece, the heating speed is fast, the efficiency is high, and there is less oxidation and decarburization on the surface of the workpiece, saving raw materials.
2. The overall heating temperature of the steel rod is uniform, with high temperature control accuracy, small temperature difference, and no pollution:
3. The heating temperature control accuracy of round steel is extremely high, and the temperature difference between the core and the surface is low. During the production process, there will be no harmful gases, smoke, strong light, or other environmental pollutants.
4. The success rate of starting the steel bar forging hot electric furnace is 100%, with high reliability: at the beginning of heating, it can be quickly started at any temperature (cold/hot) and under any load (with or without billets in the induction furnace), with a success rate of 100%. And through temperature automatic compensation technology, it quickly heats up to avoid loss of startup waste and improve production efficiency. At the end of heating, the furnace can be emptied from full load to empty load, and then a qualified billet can be produced. When a billet enters the induction furnace, the output power can be automatically adjusted under constantly changing load conditions to stabilize the billet temperature and maintain its constant temperature output. While continuing heating, the last qualified billet in the induction furnace can be completely emptied, avoiding waste loss during shutdown.
