Yuav ua li cas tiv thaiv kev tawg ntawm Kauv Welded Pipes

1. Tempering tam sim ntawd tom qab quenching: Ntau cov kauv steel yeeb nkab tawg tsis tshwm sim thaum lub sij hawm quenching thiab txias tab sis manifest tom qab raug tshem tawm ntawm lub quenching nruab nrab, tom qab ib lub sij hawm ntawm lub sij hawm, lub npe hu ua aging tawg. Cov no yog tshwm sim los ntawm qhov tseem ceeb quenching kev ntxhov siab, uas tuaj yeem tiv thaiv tau zoo los ntawm kev kub ntxhov tam sim tom qab quenching.

2. Self-Tempering Siv Residual Thaum tshav kub kub: Rau steels rhiab heev rau tawg, siv cov residual cua sov los ntawm quenching rau nws tus kheej-tempering yuav zoo tiv thaiv quenching tawg nyob rau hauv kauv steel kav.

3. Siv Lub Sijhawm Qis Qis thiab Lub Sijhawm Soaking: Rau cov hlau alloy siab, xav txog cov thermal conductivity tsis zoo vim muaj ntau yam alloy, tsim nyog preheating (ib los yog ntau zaus) yog tsim nyog.

4. Precooling Critical Areas: Rau cov cheeb tsam uas yuav ua rau kom tawg (xws li, threaded qhov, npoo, grooves), asbestos hlua los yog hlau los xij yuav tsum tau siv rau wrapping, thiab tsim nyog pre-txias yuav tsum tau ua thaum lub sij hawm quenching kom tsis txhob tawg vim ceev. cua txias hauv qhov chaw tsis muaj zog.

5. Xaiv Slow-Cooling Media: Thaum siv cov roj txias rau cov kav hlau kav, tsis txhob cia txias hauv dej. Tswj lub sij hawm siv nyob rau hauv qhov nruab nrab cua txias, feem ntau txias kom txog thaum nyob ze ntawm lub kauv steel yeeb nkab kub ua ntej cua txias. Txhawm rau tiv thaiv kom txias tawg thaum lub sij hawm ib leeg-kua quenching, ib tug high-concentration los yog nitrate ntsev tov yuav siv tau raws li qhov nruab nrab cua txias, uas yuav tiv thaiv quenching tawg nyob rau hauv complex-shaped workpieces.
