How the furnace working ?
The intermediate frequency melting furnace is mainly composed of a power supply, an furnace body with a induction coil and a crucible. Iron and steel will be put in the crucible built with refractory cement. After turned on power, an alternating magnetic field is generated in the induction coil, and then a induced eddy current is created to heat and melt iron and steel .
Furnace features:
1. Electricity fuel, various capacity 0.05T -10T, fast melting speed, 40-60 minutes /pot.
2. Low energy consumption. Induction melting is the most energy-saving melting method among electric melting furnaces.
3. Save raw material. Our furnace cause less burning loss. It can save at least 20-50 kilograms of steel raw materials per ton, compared with the gas, oil or coal-fired furnaces.
4. Reduce unqualified products by 1.5%. The application of a temperature control system can achieve precise temperature control to ensure the quality and capacity.
5. Environmental friendly. During working, there is no harmful gases and bright light created by furnaces, and workers will no longer be roasted and smoked by the coal stove under the scorching sun. It can meet the environmental requirements of govermment.
6. Easy to maintain,safe and stability.
Aluminum shell induction furnace
Aluminum shell furnaces are suitable for small foundry and semi-automatic fundry. Because aluminum shell furnace need amall space. They are easy to operate, they can be manual operation. Aluminum shell furnaces are more suitable for 50-2000kg hourly capacity.
1. Induction coils
Induction coil is the heart of aluminum shell furnaces. If its quality is poor, or its design is not reliable, it will cause up to 25% power loss. So it is very important to by a boog furnace with high quality induction coil. Our factory's induction coils are made of high-quality TUI oxygen-free copper., which are purchase from a Chinese brand-name company . The coil joint is wilded with high-silver to get high electrical conductivity and make less loss. Insulation material is set in the best inter-turn to get perfect insulation and high electrothermal efficiency.
2. Furnace frame
High quality furnace frame to have long service life. Our furnace's furnace frame is made of aluminum and magnesium alloy materials, consisting of two pieces of aluminum shells and asbestos board, insulating board and stainless copper wire rod. It is durable to furnaces are durable to service to 8-10 years.
3. Reducer
When finishing melting, the metal liquid will be poured by control reduer. RZS type reducer is a special reducer,used for induction furnace.The reducer has the advantages of small size, large speed ratio, self-locking transmission and low noise. It can be control by manual and electric control
4. Safety and big capacity. Our factory's furnaces are design bigger than its rated capacity. For example, 1 ton furnace's max capacity is 1.2 ton. So furnaces can still work smoothly when it is full. It is more safe as well. Some other furnaces supplier don't do that to save their production cost.
