    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。

    1Equipment overview

    Induction melting furnace is an efficient smelting equipment that melts scrap steel by electromagnetic induction heating. The 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 furnace. High-strength magnetic field, the steel scrap in the furnace 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. This heating method of generating thermal energy by itself inside the charge is an efficient way of melting.

    The Induction melting furnace produced by our company has the following characteristics:

    1 The input voltage is high and the output voltage is high. For the rated capacity of this program 30t Induction melting furnace, our company is designed according to the 1750V incoming line voltage specification, and the sensor load output voltage is nominally 6300V.

    2 High melting rate。 The rated design tonnage tapping amount is reached, and the continuous hot furnace smelting time is controlled at about 75 minutes。

    3 tons of steel has low energy consumption. It is 5% lower than other manufacturers' equipment, which is better than the first-class standard in GB/T30839.31-2014 "Industrial electric heating device energy consumption: medium frequency centerless Induction melting furnace"。

    4 Digital, integrated, and highly automated. The company's power system control board is a digital chip type control board. The power amplifier board is an integrated control board integrating power amplification, vulnerability detection and output. The smelting management system realizes the monitoring and management of the entire equipment by using S7-300PLC+ high-equipped host as hardware and STEP7+WINCC as software.

    2,Technical solutions and technical parameters

    2。1, Technical solutions

    For the 30t Induction melting furnace of this project, the company adopts the following technical solutions:

     Equipment configuration mode: one electric two furnaces. A furnace is normally smelted, and a furnace is used for furnace maintenance.

     Switching mode: mechanical change of furnace switch.

     Feeding method: The hydraulic feeding trolley on the platform is fed after the furnace.

    The method of steel tapping: hydraulic tilting furnace, tapping nozzle and tapping steel tapping.

     Transformer: A single 24-pulse rectifier transformer is used.

    Automatic control system: The hardware adopts S7-300 and configures industrial control computer.
