Dab tsi ntawm qhov nruab nrab zaus fais fab mov tuaj yeem ua tau raws li qhov xav tau ntawm induction melting rauv?

1 The output power requirements of the induction melting rauv for the thyristor intermediate frequency power supply.

Lub zog tso zis ntawm thyristor nruab nrab zaus fais fab mov yuav tsum ua kom tau raws li lub zog siab tshaj plaws ntawm lub qhov cub induction melting, thiab cov zis hluav taws xob tuaj yeem hloov kho tau yooj yim. Qhov no yog vim hais tias lub neej ntawm lub crucible ntawm induction melting rauv yog feem ntau txog kaum ntawm furnaces thiab nws puas. Lub qhov cub hluav taws xob yuav tsum tau rov ua dua, thiab tom qab lub qhov cub tawg tshiab tau tsim, lub qhov cub hluav taws xob qis yuav tsum tau ua rau nws. Feem ntau, lub qhov cub pib ntawm 10-20% ntawm lub zog ntsuas, thiab tom qab ntawd nce lub zog los ntawm 10% ntawm lub sijhawm tsis tu ncua kom txog thaum lub zog ntsuas hluav taws xob. Tsis tas li ntawd, nyob rau hauv cov txheej txheem ntawm lub cub tawg, thaum tus nqi yog melted, qhov muaj pes tsawg leeg ntawm tus nqi yuav tsum tau kuaj. Thaum lub sij hawm xeem, txhawm rau tiv thaiv tus nqi ntawm melting thiab boiling hnyav, qhov nruab nrab zaus fais fab mov yuav tsum txo cov zis fais fab kom cov nqi sov. Nyob rau hauv qhov kev pom ntawm qhov teeb meem saum toj no, nws yuav tsum tau hais tias thyristor nruab nrab zaus fais fab mov tuaj yeem hloov kho tau yooj yim los ntawm 10% -100% ntawm cov ntsuas tso zis hluav taws xob. Lub qhov cub diathermic siv rau forging tsis muaj txheej txheem ci.

2 Cov zis zaus yuav tsum tau ntawm qhov induction melting rauv rau thyristor nruab nrab zaus fais fab mov.

Kev sib raug zoo ntawm hluav taws xob efficiency thiab zaus ntawm ib qho induction melting rauv yog muaj feem xyuam. Pib los ntawm kev siv hluav taws xob, qhov tso zis zaus ntawm thyristor nruab nrab zaus fais fab mov tuaj yeem txiav txim siab. Piv txwv li, peb hu qhov zaus fo. Lub inductor yog ib qho inductive kauj, thiab txhawm rau txhawm rau txhawm rau lub zog reactive ntawm lub kauj, lub capacitor txuas nrog nyob rau tib lub sijhawm ntawm ob qho kawg ntawm lub kauj, uas yog LC oscillating circuit. Thaum cov zis zaus f ntawm thyristor inverter yog sib npaug rau lub ntuj oscillation zaus fo ntawm lub induction melting rauv voj, ces lub zog ntawm lub voj yog sib npaug rau 1. Lub zog siab tshaj plaws yuav tau txais nyob rau hauv induction melting rauv. Nws tuaj yeem pom los ntawm cov saum toj no hais tias lub ntuj oscillation zaus ntawm lub voj yog cuam tshuam nrog qhov tseem ceeb ntawm L thiab C. Feem ntau, tus nqi ntawm cov nyiaj them poob haujlwm capacitor C yog tsau, thaum lub inductance L hloov vim qhov kev hloov ntawm qhov. permeability coefficient ntawm cov khoom siv hluav taws xob. Lub permeability coefficient μ ntawm txias rauv hlau yog loj heev, yog li qhov inductance L yog loj, thiab thaum kub ntawm cov hlau yog siab tshaj Curie point, permeability coefficient μ = 1 ntawm cov hlau, yog li cov inductance L txo, yog li ntawd. lub induction melting rauv voj Lub ntuj oscillation zaus fo yuav hloov ntawm qis mus rau siab. Txhawm rau ua kom lub qhov cub induction smelting ib txwm tau txais lub zog siab tshaj plaws thaum lub sij hawm smelting txheej txheem, qhov no yuav tsum muaj qhov tso zis zaus f ntawm thyristor nruab nrab zaus fais fab mov tuaj yeem hloov pauv nrog kev hloov ntawm fo, thiab ib txwm khaws cov zaus tsis siv neeg taug qab.

3 Lwm qhov yuav tsum tau ua rau thyristor nruab nrab zaus fais fab mov.

Qhov no yog vim hais tias thaum lub qhov cub hluav taws kub smelting, thaum lub sij hawm nruab nrab zaus fais fab mov tsis ua hauj lwm, lub crucible yuav puas nyob rau hauv loj heev mob. Yog li ntawd, thyristor nruab nrab zaus fais fab mov yuav tsum tau ua hauj lwm ntseeg tau, thiab nws kuj yuav tsum muaj qhov tsim nyog voltage-limiting tam sim no-limiting tiv thaiv, dhau-voltage thiab over-tam sim no tiv thaiv, thiab dej txiav. Kev tiv thaiv, thiab lwm yam khoom siv tiv thaiv tsis siv neeg. Tsis tas li ntawd, nws yuav tsum tau hais tias lub thyristor nruab nrab zaus fais fab mov muaj qhov pib ua tau zoo, thiab kev pib-nres yuav tsum yooj yim.
