Lub kauv steel yeeb nkab siv cov hlau yob phaj raws li cov khoom siv raw, uas yog feem ntau nyem sov so, thiab cov kauv-shaped dabtsi yog khoov yog tsim. Lub kauv steel yeeb nkab ua los ntawm sab hauv thiab sab nrauv vuam nrog tsis siv neeg ob sab arc vuam yog siv. Cov ntaub ntawv raw yog steel yob, welded hlau, thiab solder.
Cov kauv raj decarburization pov tseg ncaj qha cuam tshuam rau nws lub neej kev pabcuam, uas yog nws qhov zoo. Nws tuaj yeem pom tias cov nyhuv ntawm decarburized pov tseg ntawm cov kav raj. Yog hais tias qhov saum npoo tau piav qhia, lub zog thiab kev puas tsuaj ntawm cov kauv raj yuav txo qis. Nws ncaj qha cuam tshuam rau kev pab cuam lub neej ntawm cov kauv raj. Yog hais tias lub decarburization txheej ntawm lub kauv raj, txheej txheej ntawm cov kauv raj yuav tsum txo qis zog, thiab thaum lub sij hawm quenching txheej txheem, nto ntawm lub workpiece yuav tsim ib tug tawg vim lub ntim ntawm lub ntim ntawm lub puab txheej.
Qhov nruab nrab uas tsim qhov chaw ntawm lub kauv raj nto yog feem ntau oxidized gases xws li oxygen, dej vapor thiab carbon dioxide. Thaum cov gases ntawm kauv raj sib cuag, nws yuav tsim oxidation thiab decarburization ntawm kauv raj. Yog li ntawd, tswj cov pa roj carbon dioxide thiab carbon dioxide nyob rau hauv lub cub tawg Qhov kev faib ua feem kuj tseem ceeb heev.
Lub hauv paus pov tseg ntawm cov kauv raj nto decarburization thawj cov cua kub pov tseg ntawm cov txheej txheem ua haujlwm rau kev pov tseg, vim hais tias lub decarburization thiab kauv raj yog nqa tawm ua ke. Thaum lub sij hawm kev kho cua sov, sim tiv thaiv cov kauv raj los ntawm kev sib cuag nrog huab cua. Qhov tsos.
