New digital energy-saving induction melting and holding furnace

Digital energy-saving induction melting furnace is a kind of energy-saving metal melting equipment designed by the principle of induction heating. It is used for smelting and alloying of gold, silver, copper, aluminum, iron, zinc, lead, tin, antimony and other metals in power metal, pneumatic manufacturing, automobile and motorcycle parts, oil and gas parts, fire fighting equipment, bullet car parts, ship blades and other metal industries and nonferrous metal casting industry. Our equipment has the advantages of fast speed, uniform heating, high thermal efficiency, low energy consumption, uniform chemical composition, no pollution, etc., is the ideal supporting equipment for die casting and casting.

Automotive Die Casting

Automotive die casting includes following processes: aluminum melting, molten aluminum transporting, withholding, casting and demolding. It could be used in all kinds of die casting machines, running machine quantity could be 6 units or more. This process produces high quality products, enables high efficiency in molten aluminum transportation, reduces working load and cost. The full automotive process could be used for both aluminum alloy as well as zinc alloy products.This process increased quality by 2-5 times, efficient increases 40%-70%. facility utilization increases by 2-3 times. Production cycles could be shortened by 30%-60%.

The technical core of Jingxing centralized melting furnace

In the preheating zone geometry and special burner technology, the preheating, heating and melting functions are realized in the same tower preheating zone. The aluminum material melts in the substructure, and the residual heat can heat the low temperature aluminum material in the upper part of the neck hot area. According to the principle of regeneration, the convection of molten aluminum and gas makes the waste heat fully utilized. From a process point of view, this means that fuel consumption and metal burn are much lower than comparable competitors. The aluminum liquid flows into the holding tank without any turbulence, and only a small amount of slag is generated. The insulation zone is separate from the melting zone. Therefore, the composition of the liquid aluminum is consistent, the liquid temperature is constant, and the quality and purity of the liquid aluminum are high.

Thermal Energy Recovery system

JINGXING thermal energy recovery system combines the preheating zone and melting zone organically by utilizing the special preheating zone geometry and the unique designed burner. While the aluminum is quickly melting at the chamber bottom, the exhausted heat is then recycled to preheat the top material. The exhaust gas could be reduced to 300 Celsius degree at the end, no extra process is specially for cooling down the tail gas. This technology enables our fuel consumption and metal burning out loss significantly lower than that of our competitors.

Economic Performance

In the process of aluminum die casting, the most important index is the burning out loss during the melting. Under the optimum condition, such as recycling material is clean & less wedge shape. The metal benefit rate could be: 

- 99% at pure aluminum. 

 - 98% with half pure and half recycled material. 

 - 98.5 with 100% recycled aluminum. 

For example, if a system melts 1000kg aluminum per hour and works 6000 hours per year. Save 1% burnout loss will save 1,140,000 CNY per year. (based on aluminum material CNY 19,000/ton).

Energy consumption

For a centralized melting furnace, metal burnout loss and energy consumption occupy 95% of its cost. These are the key factors our R&D teams are aiming at. We increase the furnace efficiency by optimize the design for system body, insulation layer and the burner. With less energy consumption, maximize metal benefit, low wearing, simplify insulation design, Sivak industrial furnaces are outstanding in high efficiency in this field.
