The special equipment for metal smelting furnace is an automatic dumping type. The smelting capacity can be from several hundred kilograms to 20T. The low power adopts IGBT type, and the high power adopts thyristor type. It is convenient and fast. It is suitable for steel, stainless steel, iron, Heating and smelting of metals such as copper, brass, gold, silver, aluminum, and aluminum alloys, and precious metals.
The dumping type intermediate frequency melting furnace is of high quality, user-friendly design, and simple in operation. It requires no professional workers. After simple training, it can be operated on the machine. It can perform timely and precise automatic control according to the current state of the workpiece being processed. Analog or digital circuit processing, adjust the power or frequency, so that the workpiece heating temperature or depth automatically adjusts to meet the process requirements. Induction heating regulation is more sophisticated, usually by adjusting the phase shift, pulse duty cycle and other parameters to adjust the heating power, once the heating temperature is determined according to the process requirements, due to its own negative feedback, it will be kept at the same temperature, Realize constant power control. The temperature uniformity is good and the temperature difference can be controlled at 1%, improving product quality and pass rate.
Induction heating smelting is more efficient than flame heating smelting. It has a high output per unit time. The heating efficiency is 30%~50% higher than that of flame heating, and the heating efficiency is high. At the same time, it can also effectively reduce the low burn of the oxide scale on the metal surface, saving material and The cost, especially for the heating of precious metals is even more important. For example, under normal circumstances, the heating of metal parts by thermoforming, the burning rate of inductively heated metal is about 0.5%, and the burning of metal heated by flame furnace is about 1%~3%, which means that induction heating saves 2% than flame heating. %about.
One of the most outstanding advantages of induction heating and flame heating is reflected in the fact that induction heating does not produce an open flame and eliminates the possibility of dangerous events such as fire and explosion. The safety is greatly improved. At the same time, it does not produce exhaust gases and dust such as carbon monoxide, carbon dioxide, and sulfur oxides. The external radiation has low heat, low noise, and the working environment can be purified and the health level can be guaranteed.
Using all-solid-state IGBT frequency conversion and power regulation, the equipment has designed a full range of protection functions, such as over-current protection, under-water protection, over-temperature protection, over-voltage protection, short-circuit protection, and phase loss protection, which greatly increase the reliability of the equipment;
