Q345B kauv raj yog nquag ua rau tawg hauv kev kho cua sov cua txias. Yog li, dab tsi yam yuav tsum muab kauv yeeb nkab manufacturers them sai sai rau qhov tshwm sim ntawm cov kab nrib pleb nyob rau hauv cov txheej txheem ntau lawm?
1. Tom qab quenching, koj yuav tsum rov qab nyob rau hauv lub sij hawm. Ntau cov kav hlau kav tsis yog tsim thaum lub sij hawm quenching thiab txias, tab sis tom qab tshem tawm cov quenching nruab nrab, nws tshwm sim tom qab ib lub sij hawm ntawm lub sij hawm, lub thiaj li hu ua timeliness tawg. Qhov no yog vim muaj kev ntxhov siab loj. Yog tias kev kho hluav taws tau ua tiav tam sim tom qab quenching, nws tuaj yeem tiv thaiv qhov tshwm sim ntawm qhov tawg raws sijhawm.
2. Tus kheej-ignition yuav tsum tau siv los siv cov quenching khib nyiab cua sov rau cov kab nrib pleb.
3. Siv cov quenching kub thiab lub sij hawm luv luv. Rau high-alloy steel, cov kav hlau kav tsis zoo ua los ntawm cov hlau alloy siab, yog li lawv yuav tsum tau ua kom sov siab (ib lossis ntau zaus).
4. Rau qhov chaw uas yooj yim rau quench (xws li threaded qhov, npoo, grooves, thiab lwm yam), koj yuav tsum siv pob zeb paj rwb ropes los ntsaws los yog qhwv nws nrog hlau. Ua rau lub kauv steel yeeb nkab.
5. Xaiv qhov nruab nrab uas maj mam txias thiab siv cov roj-cooled spiral steel kav kom tsis txhob txias hauv dej; tswv lub sij hawm thaum cov cua txias nruab nrab yog siv los ua kom txias rau thaj tsam ntawm cov kav hlau kav. Rau qhov tshwm sim, pyrine concentration lossis nitrate saline tov tuaj yeem siv los ua qhov nruab nrab cua txias, uas tuaj yeem ua rau cov khoom ua haujlwm nyuaj los ntawm kev pheej hmoo ntawm quenching tawg.
