Nkhani - -196 ℃ kutsika kwa kutentha, malo onse opitilira arc kuwotcherera zitsulo zosapanga dzimbiri

I. Mwachidule
Ndi chitukuko chofulumira cha kayendedwe ka mankhwala ndi mphamvu zapadziko lonse lapansi, akasinja osungira zitsulo zosapanga dzimbiri amagwiritsidwa ntchito kwambiri poyendetsa ndi kusunga mankhwala, chakudya ndi zakumwa, mphamvu ndi zipangizo zina. Chifukwa cha kulimba kwake kutentha kwambiri komanso kukana kwa dzimbiri, chitsulo chosapanga dzimbiri cha austenitic chimagwiritsidwa ntchito kwambiri pomanga akasinja osungira a cryogenic, zida ndi zida zazikulu za cryogenic.

Tanki yosungiramo cryogenic

Pofuna kukwaniritsa zomwe msika ukufunikira, kampani yathu yapanga mitundu yosiyanasiyana ya kutentha kotsika kwambiri, kulimba kwambiri kwazitsulo zosapanga dzimbiri za austenitic, maelekitirodi achitsulo chosapanga dzimbiri, kapangidwe kake kachitsulo komwe kamayikidwa (monga tawonetsera mu Gulu 1) ndi makina okhazikika (monga momwe tawonetsera mu Table. 2), ndipo ili ndi njira yabwino kwambiri yowotcherera pamawonekedwe onse, komanso kulimba kwa kutentha kochepa, mphamvu ya ferrite pamtengo wake (Table 3).

Kuwotchera mowongoka musanayambe komanso pambuyo pochotsa slag (DC+)

Kuwotcherera mapaipi musanayambe ndi pambuyo pochotsa slag (DC+)

4. Kusamala kwa ofukula kuwotcherera
1. Kuwotcherera kwamakono kochepa kuyenera kugwiritsidwa ntchito;
2. Sungani arc yotsika momwe mungathere;
3. Pamene arc ikugwedezeka kumbali zonse ziwiri za groove, imani kwa kanthawi, ndipo m'lifupi kugwedezeka kumayendetsedwa mkati mwa 3 nthawi ziwiri za electrode.

5.Pipeline chithunzi cha kuwotcherera consumables ntchito

Pakuti -196 ℃ otsika kutentha zimakhudza zosapanga dzimbiri kuwotcherera consumables, patatha zaka kafukufuku ndi chitukuko cha consumables kuwotcherera, ife kale lolingana kuthandiza kuwotcherera consumables kwa ndodo kuwotcherera, mitima olimba, flux mitima ndi arcs kumizidwa, ndipo apanga dzanja electrode mosalekeza arc. kuwotcherera zinthu zowotcherera pazowotcherera malo onse, ndipo ali ndi zambiri zomwe akwaniritsa pakugwiritsa ntchito uinjiniya, alandileni makasitomala kuti mukambirane ndikusankha!
