30t感应熔炼炉
1，设备概述
感应熔炼炉是一种高效的冶炼设备，通过电磁感应加热熔化废钢。能量转换过程是电磁加热，特别是整流变压器输出的工频电源转换成与AC-DC-AC负载所需频率相匹配的单相交流电源。模式，并在炉中的废钢中产生。高强度磁场，炉内废钢在磁场作用下产生强电场，形成内部涡流，从而形成熔化自身的热源。这种在电荷内部自身产生热能的加热方法是一种有效的熔化方式。
我公司生产的感应熔炼炉具有以下特点：
1输入电压高，输出电压高。对于本程序30t感应熔炼炉的额定温度容量，我公司按照1750V进线电压规范设计，传感器负载输出电压标称值为6300V。
2熔化速度快。达到额定温度设计吨位攻丝量，连续热炉熔炼时间控制在75分钟左右。
3吨钢具有低能耗。比其他厂家设备低5％，优于GB / 30839.31-2014“工业电加热设备能耗：中频无心感应熔炼炉”的标准。
4数字化，集成化和高度自动化。该公司的电源系统控制板是一种数字芯片型控制板。功放板是集成功率放大，漏洞检测和输出的集成控制板。冶炼管理系统以S7-300PLC +高配备主机为硬件，SEP7 + WINCC为软件，实现对整个设备的监控和管理。

30t Induction melting
1，Equipment overview
Induction melting is an efficient smelting equipment that melts scrap steel by electromagnetic induction heating. he energy conversion process is electro-magnetic-electric-heating, in particular, the power frequency power supply outputted by the rectifier transformer is converted into a single-phase AC power source matching the required frequency of the load in an AC-DC-AC mode, and is generated in the steel scrap in the . High-strength magnetic field, the steel scrap in the induces a strong electric field under the action of a magnetic field and forms an internal eddy current, thereby forming a heat source to melt itself. his heating method of generating thermal energy by itself inside the charge is an efficient way of melting.
heInduction melting produced by our company has the following characteristics:
1 he input voltage is high and the output voltage is high. For the rated capacity of this program 30tInduction melting , our company is designed according to the 1750V incoming line voltage specification, and the sensor load output voltage is nominally 6300V.
