1. According to the capacity requirements, determine the induction melting furnace with large tonnage.
The capacity of the induction melting furnace can be determined by the weight of the individual pieces and the weight of the molten iron required for each working day .
The standard tonnage is as follows:
250kg induction melting furnace
500kg induction melting furnace
1T induction melting furnace
2 T induction melting furnace
3T induction melting furnace
5T induction melting furnace
4. Selection of 5T induction melting furnace body structure
The capacity of the 5T induction melting furnace is small. The recommended choice is: the furnace body of the hydraulic steel shell .
The aluminum alloy structure commonly known as the aluminum alloy structure with the reducer as the tilting furnace method. The induction melting furnace of the steel structure with the hydraulic cylinder as the tilting furnace is commonly called the steel shell furnace. The steel shell furnace is a steel structure, and the aluminum shell furnace shell material is an aluminum alloy .
Nine, 5T induction melting furnace energy consumption determination
The electric power of the induction melting furnace is larger and the power is saved. The energy consumption of the molten iron of the 5T induction melting furnace : 5 5 0KW.h/t , energy consumption of molten steel 6 0 0 KW.h/t .
Ten, how to choose the induction melting furnace lining material?
1. Induction melting furnace lining material is divided into acid lining material, alkaline lining material, neutral lining material, coil cement, root melting material, medium frequency electric furnace tonnage, product molding temperature is different, it is very important to choose the appropriate lining material. jobs.
2. Induction melting furnace is a molten steel furnace using alkaline lining material mainly for fused magnesia. The induction melting furnace is a molten iron furnace. The acid lining material is a refractory material for quartz coreless induction furnace, and the material is acidic.
11. How to increase the melting speed of the induction melting furnace?
1. Increase the power of the induction frequency melting furnace intermediate frequency power supply.
2. Choose a reasonable charge size and the correct feeding method.
3. Appropriate molten iron outlet temperature.
