Shenzhen Shuangping Power Supply Technologies Co., Ltd.  

Product Name: Gold and Silver Melting Machine Spg-10-I Model NO.: SPG -10-I 10KW Brand: Shuangping Structure: Vertical Type Certification: ISO Type: Melting Trademark: shuangping Transport Package: Carton Specification: 25KG Origin: China HS Code: 8514400090 Product Description Main specifications:SPG-10 Gold melting machineUsed for melting of gold, silver, platinum and all metalsInput power:10KWOutput frequency:100--250KHZ;Input voltage: 3×380VSilica crucible can be used Melting quantity : 0.5~2KG;Advantage: Graphite crucible is not necessary, silica crucible can be used to melt scrap metals at high speed.Working theory and structure:In These series machines, series oscillating circuit is applied, through high frequency transformer, low voltage and high current power is output to go through the induction coil. The main oscillating structure is as follows: Inside These series machines, IGBT module and our third generation inverting control technology has been used, that is the soft and dual control and inverting technology. In this technology, output power and frequency can be controlled and adjusted separately, IGBT module and soft switching control technology are used in the high frequency switching circuit to control the output power. In the inverting circuit, the IGBT and frequency tracing circuit is applied to achieve high speed and accurate soft switching control. The adoption of new technologies not only improves the quality and reliability of the machine,but also solve the technology problem on large power induction heating machine and makes it possible to work 100% duty cycle. Inside the These series machines, oscillating cap is connected to the secondary coil of the transformer, so the voltage on the primary coil of the transformer is low and problems caused by high voltage such as sparks and insulations are solved thoroughly to increase the reliability and quality of the machine. At the same time, the transformer is light and small sized with low energy consuming.
