Txoj kev tsim khoom
DIN 17175 St45.8 seamless steel kav yuav ua tau los ntawm kub dov, txias dov, kub nias, kub kos duab los yog txias kos duab.
Cov kav hlau tuaj yeem raug smelted nyob rau hauv ib qho qhib hearth los yog hluav taws xob rauv raws li txoj kev oxygen tshuab, thiab tag nrho cov hlau yuav tsum tau cam khwb cia statically.
Muaj
17175 St45.8 seamless steel yeeb nkab yuav raug xa nrog kev kho cua sov kom zoo.Kev kho cua sov muaj xws li:
- Normalization.
- Annealing.
- Tempering;los ntawm quenching kub, nws tsis txias, tab sis tempered.
- Kho huab hwm coj los ntawm isothermal transformation method.

Ib daim ntawv nyias yuav tsum tau muab coj los rau ntawm qhov kawg ntawm txhua qhov puag ncig lossis square bar ingot rau kev kuaj pickling los txiav txim siab seb qhov kawg sab saum toj yog txiav txaus.Kev kuaj ultrasonic kuj tseem tuaj yeem ua rau ntawm qhov shrinkage raws li xaiv los ntawm tus neeg muag khoom.
Kuaj:
Tshuaj ntsuam xyuas muaj pes tsawg leeg
hydrostatictest
Tensile xeem
Notched cuam tshuam kuaj
Yield zog test
Nplhaib xeem
Kev kuaj tsis raug
Tube Flag
Tag nrho cov kav hlau xa mus rau kev sim thiab kev lees paub yuav tsum tau cim rau ntawm sab laug thiab sab xis ntawm cov yeeb nkab kawg ntawm 300 mm.Cov cim feem ntau yog tus lej.Nyias-walled raj kuj tuaj yeem siv rau hauv lwm hom.
Kos npe thiab xaj
Cov qib steel lossis cov khoom siv tus lej yuav tsum tau sau rau cov ntawv luv ntawm cov khoom raws li qhia hauv cov piv txwv hauv qab no:
