Introduction
Induction Melting Furnace is the device converting three phase power current into single phase intermediate frequency current and enabling metal to produce eddy current loss through electromagnetic field induction to achieve heating and melting and is applicable to melting, heating or holding of steel, copper, aluminum, zinc, tin, nickel silver and other ferrous or nonferrous metal and alloy material, as well as heating treatment prior to forging, sintering and tube-bending forming in casting and melting industries.
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. Metal 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 the metal.

Why you need furnace with two bodies?
Advantages: No delay in production. When one furnace cannot be used, connect the water-cooled cable to another furnace to continue production.
Application situation:1. When changing linning material. lining material need to be changed after a period of time, In order to prevent the furnace from being worn.
2. When furnace need to be repaire.
Advantages of Induction Melting Furnace
1. This kind of furnace has the advantages of high melting efficiency, good power saving effect, compact structure and strong overload capacity.
2. The surrounding of the furnace is low temperature, smoke less, the working environment is good .
3. Simple operation and reliable operation.
4. Fast temperature heating-up, furnace temperature easy to control, high production efficiency.
Product Details
Spare part 1:Thyristor

Why Choose us?
1.Equipped with built-in circulating water cooling system, equipment can be long-term work, no cleaning; will not be damaged furring electrical power components; so-ting long machine life;
Other manufacturers require users to directly tap water or groundwater cooling machine power; regularly with detergents water pipe cleaning equipment; and often because of poor water quality, so that equipment, furring channels, resulting in poor heat electrical components being blocked or damaged;
2.Configure automatic circuit breaker, with a reliable protection
Equipment power supply short circuit, open circuit, lack phase, power outages, discharge, and other circuit abnormalities are able to quickly and automatically cut off the power supply; in a timely manner to the equipment and network protection. To ensure the safety of the production operator.
Other manufacturers in general only with simple switch or without. They asked users to protect themselves with a fully functional power distribution equipment. Otherwise, there is short circuit, lack phase, or other circumstances occur. Will be because there is no protection, prone to accidents.
However, our equipments carry good protective function even without switch board prepared by the users.
3.One of the largest enterprises in the industry in Guangdong
We are devoted to independent R&D as well as production. A rich variety of finished products and half-finished products with complete specifications and spare parts enable us to realize fast delivery. In addition, the independent after-sales department will provide follow-up services regularly as to all the products. Furthermore, many of our engineers have been engaged in the industry for over 20 years while 80% of the intermediate-frequency equipment manufacturing companies had not yet been established15 years ago.
