It is important to choose the right smelting equipment(induction melting furnace). The progress of the iron castings is a good example of this. The cupola is the most important equipment in the field of cast iron smelting, and it is also the first place that people consider, and it will always have this status in the future. Moreover, this smelting equipment also undertakes the smelting task around 70%. The development of many cupola technology is also progressing closely with the progress of machinery and equipment, and this technology is also saving energy and reducing Energy consumption, with high productivity, has always played an important role in the field of smelting.
In many countries with developed industries, there is already a complete smelting system with large capacity and long furnace life. This system is based on cupola and medium frequency electric furnace as auxiliary system. However, in our country, the capacity of the cupola is relatively small, and the age of the stove is relatively short, and it is only suitable for air supply at normal temperature. In recent years, our country's cupola smelting technology has embarked on a road with a large capacity, a long furnace, and a hot air outside.This mode of progress is also suitable for the current production conditions and industrial technology in China, and is also more suitable for the progress of the foundry production industry. The relevant departments of the state also recommend the use of cupolas in the form of hot air, and clearly pointed out the development direction of the induction melting furnace in China at this stage.
