一、概況:
1.30噸熔鋼爐說(shuō)明
30噸熔鋼爐：主要包括脈波整流變壓器，一臺中頻電源、二臺鋼殼爐體和PLC輔助熔煉管理系統等組成。PLC輔助熔煉管理系統，不僅能夠顯示電源運行的實(shí)時(shí)數據與信息，還能夠顯示整個(gè)系統的運行狀態(tài)與信息，并且具有自動(dòng)烘爐，冷爐啟動(dòng)，故障診斷，故障信息顯示和存儲，運行信息顯示，系統狀態(tài)顯示等功能。
基本配置：24脈波整流變壓器（額定容量15000Kva），兩臺鋼殼爐體、一套中頻電源、一套逆變補償電容，電源結構為12相24脈雙整流并聯(lián)逆變結構。傾爐方式為液壓翻轉，配遠程操縱箱。

30 tons medium frequency induction melting furnace
1. Description of 30 tons of molten steel furnace
30 tons of molten steel furnace: including pulse rectifier transformer, a frequency power supply, two sets of steel melting furnace and auxiliary PLC management systems and other components. The PLC-assisted smelting management system not only displays the real-time data and information of the power supply operation, but also displays the operating status and information of the entire system, and has automatic oven, cold furnace start, fault diagnosis, fault information display and storage, and operation information display. , system status display and other functions.
Basic configuration: 24-pulse rectifier transformer (rated capacity 15000KVA), two sets of steel furnace, a frequency power supply, a set of inverters compensation capacitor structure 12 with power supply 24 double pulserectifier inverter parallel structure. The tilting method is hydraulically reversed with a remote control box.
