Lub kauv raj yog qhov ua rau tawg hauv kev kho cua sov kom txias. Dab tsi yog qhov kev saib xyuas thaum lub sijhawm tsim khoom kom tsis txhob muaj kab nrib pleb?
1. Tom qab quenching, koj yuav tsum rov qab nyob rau hauv lub sij hawm. Ntau cov kav hlau kav tsis tau tsim thaum lub sij hawm quenching thiab txias, tab sis tom qab raug tshem tawm ntawm qhov nruab nrab quenching, nws tshwm sim tom qab ib 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 siab-alloy steel, xav tias muaj ntau cov ntsiab lus alloy, lawv cov kav hlau kav muaj cov thermal conductivity tsis zoo, 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 txias rau cov kauv steel yeeb nkab ze ntawm kauv steel yeeb nkab; , Actuary los yog nitrate saline tov tuaj yeem siv los ua qhov nruab nrab txias, uas tuaj yeem ua rau cov duab nyuaj los ntawm kev pheej hmoo ntawm quenching tawg.
