30t感應(yīng)熔煉爐
1，設(shè)備概述
感應(yīng)熔煉爐是一種高效的冶煉設(shè)備，通過電磁感應(yīng)加熱熔化廢鋼。能量轉(zhuǎn)換過程是電磁加熱，特別是整流變壓器輸出的工頻電源轉(zhuǎn)換成與AC-DC-AC負載所需頻率相匹配的單相交流電源。模式，并在爐中的廢鋼中產(chǎn)生。高強度磁場，爐內(nèi)廢鋼在磁場作用下產(chǎn)生強電場，形成內(nèi)部渦流，從而形成熔化自身的熱源。這種在電荷內(nèi)部自身產(chǎn)生熱能的加熱方法是一種有效的熔化方式。
我公司生產(chǎn)的感應(yīng)熔煉爐具有以下特點：
1輸入電壓高，輸出電壓高。對于本程序30t感應(yīng)熔煉爐的額定溫度容量，我公司按照1750V進線電壓規(guī)范設(shè)計，傳感器負載輸出電壓標(biāo)稱值為6300V。
2熔化速度快。達到額定溫度設(shè)計噸位攻絲量，連續(xù)熱爐熔煉時間控制在75分鐘左右。
3噸鋼具有低能耗。比其他廠家設(shè)備低5％，優(yōu)于GB / 30839.31-2014“工業(yè)電加熱設(shè)備能耗：中頻無心感應(yīng)熔煉爐”的標(biāo)準(zhǔn)。
4數(shù)字化，集成化和高度自動化。該公司的電源系統(tǒng)控制板是一種數(shù)字芯片型控制板。功放板是集成功率放大，漏洞檢測和輸出的集成控制板。冶煉管理系統(tǒng)以S7-300PLC +高配備主機為硬件，SEP7 + WINCC為軟件，實現(xiàn)對整個設(shè)備的監(jiān)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.
