Fitaccen aiki na induction narkewa tanderu
Outstanding performance of injin wutar lantarki
The frequency of the power supply used by the induction melting furnace is in the range of 150-10000Hz, and its common frequency is 150-2500Hz. The induction melting furnace is now widely used in the production of steel and other non-ferrous alloys, and is also widely used in the foundry industry.
Dauki induction narkewa kamar misali. Tun lokacin da kamfanin BBC na Switzerland ya sami nasarar samar da wutar lantarki ta farko ta thyristor don narke a cikin 1966, manyan ƙasashe masu masana’antu sun yi nasara gabatar da wannan samfurin, wanda ba da daɗewa ba ya maye gurbin na’urar samar da wutar lantarki ta gargajiya. Saboda matsakaicin mitar wutar lantarki na thyristor yana da babban inganci, gajeriyar zagayowar masana’anta, shigarwa mai sauƙi, da sauƙin sarrafawa ta atomatik, kewayon aikace-aikacen sa ya ƙunshi fannonin samar da masana’antu daban-daban kamar smelting, diathermy, quenching, sintering, da brazing. A halin yanzu, an sami ci gaba mai mahimmanci a matakin fasaha da matakin kayan aiki na narke wutar lantarki ta duniya, galibi kamar haka:
Ƙarfin wutar lantarki yana daga ƙarami zuwa babba, mafi girman wutar lantarki zai iya kaiwa 30t, kuma wutar lantarki na iya kaiwa 40-50t;
Ƙarfin wutar lantarki daga ƙananan zuwa babba, ciki har da 1000kW, 5000kW, 8000kW, 10000kW, 12000kW, da dai sauransu;
Daga wutar lantarki don fitar da tanderun narkewa don haɓaka ɗaya zuwa biyu (narkewa ɗaya, adana zafi ɗaya, da’ira), ko ma “ɗaya zuwa uku”;
An daidaita murhun narkewar shigar da wutar lantarki tare da gyaran ƙarfe na ƙarfe ko tanderun AOD don cimma sakamako mai kyau;
Muhimmiyar nasara a cikin da’irar samar da wutar lantarki, daga kashi uku na 6-pulse, 12-phase 24-pulse zuwa XNUMX-phase XNUMX-pulse, amincin da’irar thyristor yana da girma, kuma ana iya daidaita na’urar samar da wutar lantarki tare da magani. na babban tsari na jituwa;
An inganta matakin kulawa, kuma ana iya amfani da tsarin PLC mafi dacewa don sarrafa ma’aunin wutar lantarki na tanda;
Babban jiki da kayan taimako sun fi cikakke.
