Sekoli se teng ka har'a karolo e ka hare ea peipi ea tšepe, e tšoanang le mokoti oa boholo ba thollo ea soya. Bongata ba maqeba a na le lintho tse tsoang kantle ho naha tse 'mala o moputsoa-o sootho kapa o moputsoa-o motšo. Lintlha tse susumetsang tsa scarring ka hare li kenyelletsa: deoxidizer, ts'ebetso ea ente, mandrel lubrication le lintlha tse ling. Ha re latele moetsi oa li-tube tsa carbon steel ho bona mokhoa oa ho laola bofokoli bo ka hare ba li-tubes tsa tšepe tse se nang seam:

1. Deoxidizer

The oxide e hlokehang ho ba boemong ba ho qhibiliha ha mandrel pele ho hlajoa. Matla a eona le litlhoko tse ling tse thata.

1) Boholo ba karoloana ea phofo ea deoxidizer hangata bo hlokahala hore bo be haufi le 16 mesh.
2) Likahare tsa sodium stearate ka har'a moemeli oa scavenging li lokela ho fihla ho feta 12%, e le hore li ka chesa ka ho feletseng lumen ea capillary.
3) Fumana palo ea ente ea deoxidizer ho ea ka sebaka se ka hare sa capillary, ka kakaretso 1.5-2.0g / dm2, 'me palo ea deoxidizer e fafalitsoeng ke capillary ka bophara le bolelele bo fapaneng bo fapane.

2. Litekanyetso tsa ts'ebetso ea ente

1) Khatello ea ente e lokela ho tsamaisana le bophara le bolelele ba capillary, e sa tiiseng feela ho foka ho matla le ho tuka ho lekaneng, empa hape ho thibela mokelikeli o sa chesoang ka ho feletseng hore o se ke oa fefoloa ho tloha ho capillary ka moea o phallang.
2) Nako ea ho hloekisa ea moetsi oa liphaephe tsa tšepe e se nang seamless e lokela ho fetoloa ho ea ka ho toba le bolelele ba capillary, 'me tekanyetso ke hore ha ho na oxide ea tšepe e emisitsoeng ka har'a capillary pele e phatloha.
3) Bophahamo ba nozzle bo lokela ho fetoloa ho ea ka bophara ba capillary ho netefatsa setsi se setle. Nozzle e lokela ho hloekisoa hang ka nako e 'ngoe le e' ngoe, 'me molomo o lokela ho tlosoa bakeng sa ho hloekisa ka mor'a ho koala nako e telele. E le ho etsa bonnete ba hore "deoxidizing agent" e butsoe ka ho lekana leboteng le ka hare la capillary, ho sebelisoa sesebelisoa sa boikhethelo seteisheneng bakeng sa ho butsoela "deoxidizing agent", 'me e na le khatello ea moea e potolohang.

3. Mandrel lubrication

Haeba phello ea lubrication ea mandrel e se e ntle kapa mocheso oa mandrel lubricant o le tlase haholo, ho tla ba le leqeba le ka hare. E le ho eketsa mocheso oa mandrel, mokhoa o le mong feela oa ho pholile oa metsi o ka amoheloang. Nakong ea ts'ebetso ea tlhahiso, hoa hlokahala ho laola ka thata mocheso oa mandrel ho netefatsa hore mocheso oa holim'a mandrel ke 80-120 ° C pele o fafatsa lubricant, 'me mocheso oa mandrel ha oa lokela ho feta 120 ° C. ka nako e telele, e le ho etsa bonnete ba hore lubricant e holim'a metsi e omme ebile e teteaneng pele ho phunya pele , Mookameli o lokela ho hlahloba kamehla boemo ba lubrication ea mandrel.
