Waxqabadka aadka u wanaagsan ee foornada dhalaalidda induction
Outstanding performance of foornada dhalinta dhalaalaysa
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.
Tusaale ahaan u soo qaado foornada dhalaalka induction. Tan iyo markii shirkadda Swiss BBC ay si guul leh u soo saartay tamartii ugu horreysay ee thyristor dhexdhexaad ah oo loogu talagalay dhalaalidda kicinta 1966, waddammada warshadaha waaweyn ayaa si isdaba joog ah u soo bandhigay badeecadan, taasoo isla markiiba beddeshay qalabkii soo noqnoqda ee soo noqnoqda ee korontada. Sababtoo ah sahayda tamarta dhexdhexaadka ah ee thyristor waxay leedahay hufnaan sare, wareegga wax soo saarka gaaban, rakibaadda fudud, iyo xakamaynta tooska ah ee fudud, kala duwanaanshaheeda codsigu wuxuu daboolayaa noocyo kala duwan oo wax soo saarka warshadaha sida dhalada, diathermy, deminta, sintering, iyo brazing. Waqtigan xaadirka ah, waxaa jiray horumarro muhiim ah oo laga gaaray heerka farsamada iyo heerka qalabaynta foornada dhalaalka ee caalamiga ah, badiyaa sida soo socota:
Awoodda foornada waa laga bilaabo yar ilaa weyn, foornada dhalaalaysa ee ugu sareysa waxay gaari kartaa 30t, foornada xajinta waxay gaari kartaa 40-50t;
Awooddu waxay u dhaxaysaa mid yar ilaa weyn, oo ay ku jiraan 1000kW, 5000kW, 8000kW, 10000kW, 12000kW, iwm;
Laga soo bilaabo sahay koronto si loo kaxeeyo foornada dhalaalka induction si loo horumariyo hal ilaa laba (hal dhalaalid, hal kulayl ilaalin, wareeg taxane ah), ama xitaa “hal ilaa saddex”;
Foornada dhalaalaysa induction waxay la mid tahay sifaynta ka baxsan foornada ee birta ama foornada AOD si loo gaaro natiijooyin wanaagsan;
Horumarka muhiimka ah ee wareegga korontada, laga bilaabo saddex-waji 6-pulse, lix-waji 12-pulse ilaa laba iyo toban-waji 24-pulse, isku-kalsoonaanta wareegga thyristor waa mid sarreeya, qalabka korantada waxaa lagu dhejin karaa daaweynta oo ka mid ah harmonics-sare;
Heerka xakamaynta ayaa la wanaajiyey, iyo nidaamka PLC ayaa si aad ah loogu isticmaali karaa si wax ku ool ah loo xakameeyo xuduudaha korantada ee foornada;
Jidhka ugu muhiimsan iyo qalabka caawiye ayaa aad u dhammaystiran.
