Thaum lub sij hawm ua cov txheej txheem cua sov ntawm cov hlau, qhov saum npoo ntawm cov hlau qhov chaw yuav tsim cov qib sib txawv ntawm oxidation nrog rau qhov siab ntawm cov cua sov thiab lub sij hawm ntev, thiab cov thickness sib txawv ntawm oxide. Txhawm rau txhim kho qhov zoo ntawm qhov chaw thiab qhov loj thiab qhov tseeb ntawm cov yeeb nkab steel, thaum lub sij hawm kub dov ntawm cov yeeb nkab steel, high-pressure water de-scales yog siv los tshem tawm cov oxide.
Nyob rau hauv cov txheej txheem ntawm kev kho cua sov cua sov, oxide daim tawv nqaij kuj yuav tsim nyob rau hauv lub nto ntawm cov yeeb nkab steel, thiab cov txheej txheem ntawm nce siab-siab dej de-scales muaj cov nram qab no zoo:
(1) Zoo li cov txheej txheem dov, cov txheej txheem tshem tawm dej siab tuaj yeem txhim kho qhov zoo ntawm cov yeeb nkab steel;
(2) Tom qab cov yeeb nkab steel raug tshem tawm los ntawm cov nplai kom tshem tawm cov oxidation ntawm daim tawv nqaij, cov yeeb nkab steel yog sib npaug txias thiab cov cua sov hloov pauv nrawm thaum lub sijhawm quenching, uas tuaj yeem txo qhov deformation ntawm quenching thiab ua kom txias ceev ntawm cov yeeb nkab steel;
(3) Thaum lub sijhawm ua haujlwm ncaj qha ntawm cov yeeb nkab steel tom qab kev kho cua sov, cov yeeb nkab steel yuav tsim kev sib txhuam zoo rau cov menyuam ncaj thiab ua rau cov menyuam hnav. Thaum lub npoo ntawm cov yeeb nkab steel yog oxide tuaj yeem txo cov menyuam hnav;
(4) Tsis muaj kev puas tsuaj tom qab kev kho cua sov ntawm cov kav dej steel. Yog tias qhov chaw ntawm qhov chaw yog oxide, nws yuav cuam tshuam rau kev tshawb pom. Hauv qhov xwm txheej hnyav, cov nplai yuav tsis ua, thiab cov txheej txheem ntsuas tuaj yeem zam qhov xwm txheej no.
