Oxidation yog hais txog lub luag haujlwm ntawm CO2, H2O, thiab O2 hauv cov pa roj thaum cua sov. Ntawd yog, kub hnyiab), txo cov khoom siv, thiab tib lub sijhawm, qhov sib xyaw ntawm cov hlau oxide ntawm daim tawv nqaij yuav ua rau cov khoom yaig ntawm cov khoom siv refractory los txo cov kev siv lub qhov cub. Tsis tas li ntawd, cov cua kub ntawm cov hlau oxide ntawm daim tawv nqaij yog qis dua cov hlau, cuam tshuam rau cov cua kub ntawm cov billet.
1. Qhov kub ntawm cov yeeb nkab steel kub steel tsis oxidize ua ntej 800 degree C, thiab qhov kub ntawm lub raj lub billet mus txog 800 degree C los yog siab dua. Kev hloov pauv ceev yog nce ntxiv;
2. Lub sij hawm kub kub nyob, qhov ntev ntawm lub raj nres nyob rau hauv qhov chaw kub, qhov ntau oxidized thiab hlawv, qhov hnyav dua;
3. Qhov chaw oxidized ntawm lub cub tawg, qhov hnyav dua qhov oxidation thiab kev puas tsuaj.
Qhov cuam tshuam ntawm peb qhov saum toj no yog qhov pib 6: 3: 1.
Dalvation -galvanized steel yeeb nkab kho cua sov kab high-pressure dej tshem tawm teev
Thaum lub sij hawm ua cov txheej txheem cua sov ntawm cov hlau, qhov saum npoo ntawm cov hlau yuav tsim cov qib sib txawv ntawm oxidation nrog qhov siab ntawm cov cua sov thiab lub sij hawm ntev, thiab tsim 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 sijhawm kub dov ntawm cov yeeb nkab steel, cov txheej txheem ntawm kev tshem tawm dej siab yog siv los tshem tawm cov pa oxygen.
Nyob rau hauv cov txheej txheem ntawm kev kho cua sov cua sov, oxide daim tawv nqaij kuj yuav raug tsim nyob rau ntawm qhov chaw ntawm cov yeeb nkab steel, thiab cov txheej txheem ntawm kev nce siab-siab dej de-scales muaj cov nram qab no zoo:
1. Zoo li cov txheej txheem dov, cov txheej txheem ntawm kev tshem tawm cov 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 oxide, cov yeeb nkab steel yog txias sib npaug thiab cov cua kub sib hloov tau nrawm dua thaum lub sij hawm quenching, uas tuaj yeem txo qhov quenching deformation ntawm cov yeeb nkab steel thiab txhim kho qhov txias ceev;
3. Thaum cov txheej txheem ncaj nraim 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 muaj oxide nyob rau saum npoo ntawm cov yeeb nkab steel 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, qhov ntsuas yuav tsis ua, thiab qhov xwm txheej no tuaj yeem zam tau.
