Chimiro chekugadzira che Vacuum mhepo choto musuo

Chimiro chegonhi chevacuum atmosphere furemu inoumbwa nesimbi, cast iron trim uye refractory insulation lining. Kune yakaderera-tembiricha kupisa kupisa mavira, cast iron trim haidiwi. Iyo furemu yakashongedzwa neI-beam kana chiteshi simbi, ukobvu hwesimbi yakatenderedza ndiro 10 kusvika 20mm, ukobvu hwekunze kwesimbi ndiro yelining inogona kuita 3 kusvika 4mm, ukobvu hwemalugs ndeye 16 kusvika 40mm, uye ukobvu hwembabvu i6 kusvika 10mm, ese anoshandisa Q235-A carbon structure Simbi kugadzira.

Vacuum atmosphere choto chegonhi rinosimudza lugs l1=0.5B, B ndihwo hupamhi hwegonhi rechoto furemu, uye kurongeka kwepakati kweI-beam kana chiteshi chesimbi il2=600 kusvika 800mm. Musuwo wekuchekeresa wevacuum atmosphere vira kazhinji HT200 grey cast iron, uye muchoto wegonhi rechoto chetrolley choto chekupisa choto kazhinji RQTSi4 yakakwira silicon inodzivirira kupisa simbi yakakandwa.

Iro musuwo wegonhi rekutungamira ndiro yevacuum atmosphere furnace yakakamurwa kuva mvura-yakatonhorera uye isina-mvura-yakatonhodzwa zvivakwa. Iyo isina-mvura-yakatonhodzwa yevira regonhi rekutungamira ndiro chimiro chinogona kushandiswa mukupisa mavhiri uye kupisa kupisa kupisa. Kana ichishandiswa muchoto chekudziya, RQTSi4 yakakwira silicon inodzivirira kupisa simbi inoshandiswa, uye zvikamu zvasara zvinogadzirwa neHT200 grey cast iron. Mvura-yakatonhodzwa musuwo wegonhi rekutungamira ndiro inoratidzirwa nekureruka kurema, kudiki deformation uye hupenyu hurefu hwebasa. Iyo yemvura-yakatonhodzwa mugonhi regidhi ndiro yakasungwa ne12 ~ 15mm simbi ndiro. Mushure mekuputika, kuedzwa kwemvura kunodiwa. Kazhinji, 0.5MPa mvura inopfuudzwa mukati. Iyo weld inokodzera kana weld ikasadonha mukati me5 maminetsi.

Iyo yevira remusuwo wevira yevacuum atmosphere furnace inoumbwa nezvidhinha zvinoramba uye zvidhinha zvekudzivirira, kana inoumbwa nezvidhinha zvinoramba, insulation fillers uye asbestos board. Parizvino, iyo yese-fiber yevira remusuwo lining layer yakagadzirwa nerefractory fiber inonzwa (gumbeze) inowanzoshandiswa. .
