Kev nyab xeeb txoj kev ua haujlwm ntawm hlau melting rauv

Kev nyab xeeb txoj kev ua haujlwm ntawm hlau melting rauv

(1) Kev npaj thiab tshuaj xyuas ua ntej smelting

①The equipment must be inspected in detail. Check the shift record and report the problem in time. Do not open the furnace without treatment.

②Check whether the instruments of the three major electrical, hydraulic and cooling water systems are in good condition.

③ Tshawb xyuas seb puas muaj kev hloov xim, sintering, los yog xoob ntawm kev sib txuas ntawm lub busbar, dej-txias cable, thiab cov khoom siv hluav taws xob.

④ Tshawb xyuas seb puas muaj cov dej xau hauv hydraulic thiab dej txias. Yog tias muaj teeb meem, nws yuav tsum tau daws tam sim ntawd, thiab cov dej txias yuav tsum tau ua thaum cov dej txias tsis txaus.

⑤ Tshawb xyuas seb qhov kev tiv thaiv kev nyab xeeb ntawm cov cuab yeej puas puas lawm.

⑥ Tshawb xyuas tias cov ntaub thaiv npog tiv thaiv, cov ntaub ntawv insulating thiab lwm yam khoom siv tiv thaiv nyob rau hauv qhov chaw.

⑦ Tshawb xyuas seb cov khoom siv cuam tshuam ntawm cov hlau melting rauv puas zoo.

(2) Cov kauj ruam ua haujlwm hauv smelting

① Paub meej tias cov cuab yeej muaj kev nyab xeeb thiab zoo li qub, thiab smelt raws li qhov tau teev tseg “hlau melting rauv tawg tawg smelting txheej txheem”.

② Lub zog tseem ceeb hauv chav tswj ntawm cov hlau melting rauv muab lub zog rau cov hlau melting rauv.

③Start the cooling water pump of the VIP power supply and the cooling water pump of the furnace body. Check that there is no leakage in the water and oil circuits, and the pressure gauge display should be normal.

④ Pib qhov kev tswj xyuas raws li qhov xwm txheej tiag tiag ntawm lub tshuab cua txias sab nraum zoov.

⑤ Xa high-voltage fais fab mov raws li high-voltage fais fab kis tau tus mob txoj cai.

⑥ Xaiv lub ntsiab fais fab ntawm cov hlau melting rauv raws li qhov xav tau tiag tiag. Ntawd yog, tig rau VIP tswj lub hwj chim tseem ceeb hloov, xaiv qhov hloov pauv kev rho tawm thiab kaw nws, thiab tom qab ntawd kaw qhov hluav taws xob hloov hluav taws xob ntawm lub ntsiab Circuit Court.

⑦Press the red stop button to reset the AC interrupter.

⑧ Tshawb xyuas thiab ntsuas cov cuab yeej tiv thaiv ntawm lub tshuab nqus dej hauv av yuav tsum tsis tu ncua.

⑨ Xaiv lub smelting tswj hom ntawm cov hlau melting rauv, pib lub high-frequency tswj mus, thiab kho lub pob qhov rooj tswj kom tsim nyog lub hwj chim rau smelting.

(3) Cov kauj ruam ua haujlwm ntawm smelting nres

① Tig lub pob qhov rooj tswj mus rau xoom thiab tua lub tshuab hluav taws xob ntau zaus.

②Start the timing switch of the water pump, and the time setting should be greater than 8h.

③Turn off the two circuit breaker switches of the main circuit, turn off the key switch of the VIP control power supply, and remove it

qhov tseem ceeb.

④ Tshem tawm qhov kev rho tawm ntawm lub ntsiab Circuit Court.

⑤ Tig tawm qhov hloov hluav taws xob siab, thiab tua hluav taws xob ntawm cov khoom siv cuam tshuam nrog cov hlau melting rauv.

(4) Precautions for smelting

① Tus neeg teb xov tooj nyob rau hauv pem hauv ntej ntawm lub cub tawg yuav tsum tua lub high-frequency tswj hloov thaum slagging, ntsuas kub, sampling, thiab tawm ntawm lub cub tawg.

② Thaum lub sij hawm smelting, yuav tsum muaj ib tug neeg nyob rau hauv pem hauv ntej ntawm lub cub tawg los tiv thaiv tej yam txawv txav nyob rau hauv pem hauv ntej ntawm lub cub tawg.

③ Nyob rau hauv cov xwm txheej tshwj xeeb xws li hluav taws xob hluav taws xob, tam sim ntawd pib lub DC twj tso kua mis txias, thiab tib lub sij hawm pib lub twj tso kua mis roj rau cov hlau molten. Yog tias lub twj tso kua mis DC tsis ua haujlwm, qhib lub tshuab dej txias thaum muaj xwm ceev.

④ Lub twj tso kua mis ncaj nraim thiab cov roj twj tso kua mis hydraulic raug sim tawm ib hlis ib zaug, thiab cov txiaj ntsig tau raug kaw.

⑤ Tom qab smelting tiav lawm, npaj tag nrho cov cuab yeej, cov khoom siv thiab cov khoom siv raw, thiab ntxuav qhov chaw ua haujlwm.
