Dab tsi yog cov khawv koob uas ua liab raw cov khoom raw thiaj li nrov nyob rau hauv kev lag luam?
Chrome corundum rau kev sib tsoo
Chromium Corundum yog qhov tsim tshwj xeeb tsim kev siv siab {{purity alumina (al}o₃) raws li ib qho ntawm 1.5% -3.0% oxide oxide (cr₂o₃). It is then melted in an electric arc furnace at temperatures above 2000℃and cooled to crystallize, forming a high-grade abrasive. Lub xub ntiag ntawm fused feded txhuas oxide muab nws Denser Crystal qauv, siab dua, thiab muaj zog hnav coj tawm tsam. Nws cov xim muaj xim los ntawm liab dawb kom huv si- pi}}} pa, thiab machines kub- kub ua hauj lwm.
Cov khoom lag luam uas muaj zog yoog tau yog ib txwm nrov, tsis hais lub sijhawm lossis qhov chaw. Peb lub siab -}}} roj chomium fused txhuas oxide ua kom cov iav siab heev thiab ua kom muaj kev sib tsoo ntawm cov hlau stainless thiab pwm. Hauv polazing ceramic, iav, thiab alloy qhov chaw, nws muaj kub kub tiv thaiv kev ntxhov siab thermal, ua rau kev ua tau zoo heev. Tsis tas li ntawd, nws txhim kho kev txiav ua haujlwm thiab kev sib tsoo hauv lub taub hau thiab sib tsoo {{5} Taug kev ywj pheej, ntsib qhov yuav tsum muaj ntawm cov kev sib tsoo.
Chrome corundum rau txiav
Siab hardness thiab siab - kub ua kom ntseeg tau tias chromium fused ua kom txhuas oxide tswj nws cov ntse txawm nyob hauv qab hnyav thiab kub. Hnav zoo heev yog qhov tseem ceeb rau kev ncua sij hawm ntawm kev txiav cov cuab yeej. Txhawm rau kom muaj kev sib xws ntawm peb cov khoom Chrome corundum, peb tau ua tiav cov khoom ua tiav, kev tsim kho zoo heev, thiab ib qho loj me me rau ± 1.5%.
Kev txiav kev ua tau yog qhov tseem ceeb txiav txim siab ntawm kev ua cov nqi ceev thiab ntau lawm, thaum coj lub neej cuam tshuam cuam tshuam ntau zaus ntawm cov cuab yeej thiab sib tsoo cov log hloov. Tsis tas li ntawd, tswj thermal ruaj khov txwv tsis pub cov nplej muag thiab txo cov kev ua tau zoo ntawm qhov kub. Cov khoom tseem ceeb no ua rau peb chrome corundum ntxiv tiv taus rau kev txwv tsis pub cua sov ntawm cov xuab zeb alumina ruaj khov, tswj ruaj khov thiab ntse txiav ntug thaum lub sijhawm hlau.
