Choyamba, kuti zitsimikizire bwino kuti mpweya wodutsa pamwamba pa njerwa yotulutsa mpweya, uyenera kupangidwa munjira yazitsulo zolowera mumtsinje wa mpweya wabwino, ndipo pochita izi, tiyenera kuonetsetsa kuti chitsulocho chili ndi mtengo wapatali. kulowetsedwa Pofuna kuwongolera zinthu zachibale za njerwa yodutsa mpweya, kunyowa kwa njerwa yodutsa mpweya kumatha kuyendetsedwa bwino ndi chitsulo chosungunuka; kuonjezera apo, ntchito ya njerwa yodutsa mpweya idzakhudzidwa ndi chilengedwe chomwe chikugwiritsidwa ntchito. The scouring amphamvu zitsulo zosungunuka katundu, kotero kuti zinthu za thupi njerwa chofunika kukhala mkulu zokwanira structural katundu, ndi mkulu-kutentha zimango ndi zina zokhudzana katundu pa kupanga.

Akuti izi mkulu-ntchito njerwa zopumira imagwiritsidwa ntchito pakanthawi kochepa. Choncho, zipangizo zonse za thupi njerwa ayenera kukhala wamphamvu matenthedwe kukana mantha pansi pa zochita za kuzizira kwambiri ndi kutentha. Kuchita bwino komanso kulimba kwa anti-stripping performance, etc. Ndi chifukwa cha ntchito yabwino yotereyi kuti ikadzagwiritsidwa ntchito ndi kukonzanso pambuyo pake, imayenera kuyeretsa kuwotcha kwa okosijeni, ndikuwongolera kukana kwa okosijeni kwa zinthu za njerwa, kuti zitha kugwiritsidwa ntchito popanga mtsogolo. Bwino kusintha moyo utumiki wa mankhwala ake.

Choncho, kuti bwino kukumana katundu osiyanasiyana chofunika m`kati ntchito, kupanga mtundu uwu wa luso njerwa, m`pofunika mogwira kuchepetsa zili ufa wabwino ndi kuonjezera zili chofunika ndale tinthu nkhani. Chiŵerengero choyenera. Panthawi imodzimodziyo, zipangizo zake zopangira zimayenera kugwiritsa ntchito ma profiles a corundum, komanso mbiri ya corundum monga zirconium yosakanikirana monga aggregates, pamene akugwiritsa ntchito micronized yaiwisi monga activated alumina, ndi chiyero chachikulu High-performance fused spinel, ndi wapadera chromium okusayidi wobiriwira ndi zipangizo zina mbiri, kupanga masanjidwewo chiŵerengero. Pochita izi, tiyenera kulabadira kuchuluka kwa simenti, chitsulo cha chromium ndi zinthu zina munjira iyi, zomwe ziyenera kukhala zochepa kuposa zida zina zamtundu wa corundum.

Izi makamaka chifukwa chakuti zopangira izi zimakhala ndi zinthu zofanana zakuthupi ndi mankhwala, monga kukana moto waukulu, komanso kukhazikika kwamphamvu kwa kutentha kwa kutentha. Pakugwiritsa ntchito, amakhalanso ndi kukana kolimba kwa kukokoloka kwa slag. Imakhala ndi zinthu zotsika zotsika komanso zotsika zotsika kutentha kuti ziwonetse magwiridwe antchito a njerwa zolowera mpweya mu kutentha koyenera komwe ntchito yonyamula imakhala yofewa.
