Txheej Txheem rau ST52.3 Ncaj Seam Steel Pipes:

1. Forging: Siv lub zog rov ua dua ntawm lub forging rauj lossis lub siab ntawm lub xovxwm los hloov cov duab thiab qhov loj ntawm qhov khoob rau hauv cov duab uas xav tau.

2. Extrusion: Txoj kev no yuav tsum tau muab cov hlau tso rau hauv lub extruder kaw, siv lub siab ntawm ib qho kawg kom extrude cov hlau los ntawm qhov teev qhov tuag, yog li tau txais cov khoom tiav nrog tib lub duab thiab loj. Nws yog tsuas yog siv rau zus tau tej cov ntaub ntawv uas tsis yog-ferrous hlau.

3. Rolling: Qhov no yog txoj kev ua haujlwm siab nyob rau hauv uas lub steel billet kis tau los ntawm qhov sib txawv ntawm ib khub ntawm rotating rolls, thiab vim yog compression ntawm cov yob, cov khoom seem ntawm qhov cross-section yog txo thaum nws qhov ntev nce.

4. Kev kos duab: Nws yog ib txoj hauv kev ua rau cov hlau blanks uas twb tau dov, txo cov ntu ntu thiab ua kom ntev los ntawm kev hla lawv los ntawm qhov tuag qhov. Txoj kev no feem ntau yog siv rau kev ua haujlwm txias.
