Hlau pas nrig nruam induction cua sov rauv

Steel rod continuous induction cua sov cua sov

In steel and machinery manufacturing plants, when the output is large, the continuous induction heating method for steel bars is now used more. After the steel rod is heated, it is subjected to hot shearing, and then die forging or stamping.

Daim duab 12-51 yog ib txheej steel pas nrig nruab nrab zaus nruam induction cua sov rauv. Cov pas nrig steel yog muab tso rau ntawm lub vibrating platform ntawm cov khoom noj khib nyiab, thiab raug rub mus rau txoj kev noj zaub mov los ntawm kev rub lub tshuab tsis siv neeg, uas yog tsav los ntawm kev tswj tsis muaj zog DC lub cev muaj zog. Pub cov menyuam pub lub bar rau inductor rau induction cua sov. Tus naj npawb ntawm cov sensors yog txiav txim siab raws li txoj kab uas hla ntawm lub bar thiab cov zis. Cov sensors no tau teem rau hauv txoj kab ncaj nraim. Qhov no txuas ntxiv induction cua sov rauv yog siv los ua kom sov steel tuav nrog qhov ntev ntawm Φ55 – Φ 100 mm thiab ntev ntawm 6m. Cov cua kub kub yog t = 1200 ℃ ± 25Y, uas yog, qhov kub thiab txias sib txawv ntawm qhov chaw thiab cov tub ntxhais ntawm qhov bar yog 50 ℃, thiab cov khoom tsim tau yog 3600kg / h. Lub thyristor inverter yog powered, zaus yog 1100Hz, lub hwj chim yog 1 320kW, thiab cov tsis muaj feem xyuam rau inductor muaj nyob rau hauv Table 12-10.

Cov inductors tau muab faib ua peb pawg raws li txoj kab uas hla ntawm steel rods. Thaum cua sov steel rods ntawm txawv diameters, cov coj inductors yuav tsum tau hloov. Txog li 10 inductors tuaj yeem ntsia tau rau ntawm qhov cub induction cua sov. Lub coil ntev ntawm lub inductor yog 550mm. Tom qab kev kho cov rwb thaiv tsev, lub kauj yog lined nrog cov cua sov-insulating txheej ua los ntawm cov ntxhia wool thiab cov cua sov-resistant txheej ua los ntawm cov ntaub ntawv refractory. Thaum kawg, ib qho asbestos cement board yog siv los ua ib lub thawv, thiab cov kauj yog tsau rau hauv lub thawv. . Qhov ntev ntawm txhua lub thawv yog 600mm, qhov kev ncua deb nruab nrab ntawm lub thawv thiab lub thawv yog 200mm, thiab kev txhawb nqa kev pub noj yog nruab nrab ntawm.

Lub hwj chim mov ntawm lub inductor yog tias ob lub inductors txuas nrog hauv series ua ntej, thiab tom qab ntawd txuas mus rau qhov sib npaug ntawm cov khoom siv hluav taws xob, raws li pom hauv daim duab 12-52.

Daim duab 12-53 yog cov kab hluav taws xob txuas ntxiv ua hluav taws xob tsim los ntawm lub tuam txhab txawv teb chaws nrog lub zog ntawm 12MW, tag nrho ntawm 26 inductors, thiab tag nrho ntev ntawm 157 m (47.86m).
