Tus yuam sij rau kev txiav txim siab cov khoom zoo ntawm cov cement mortar mixing cog yog nyob rau hauv kev sib koom ua ke ntawm kev tshuaj ntsuam xyuas, kev ntsuam xyuas hardness, kev tshuaj ntsuam xyuas, thiab kev txheeb xyuas cov txheej txheem, siv cov hom phiaj ntsuas rau cov khoom sib txawv.
Kev txiav txim siab zoo ntawm Kev Hnav Siab-Resistant Alloy Steel
Qhov no yog cov khoom siv tseem ceeb uas siv rau hauv cov qauv tseem ceeb ntawm cov nroj tsuag sib xyaw (xws li cov thav duab thiab cov khoom siv conveyor), thiab nws qhov zoo cuam tshuam ncaj qha rau tag nrho cov khoom ruaj khov.
Kev Ntsuam Xyuas Hardness: Siv lub portable Rockwell hardness tester (HRC), ntawm -qhov chaw sim yog ua. High-zoo hnav zoo- cov hlau tsis muaj zog yuav tsum muaj qhov tawv ntawm HRC45 lossis siab dua. Yog tias nws qis dua HRC40, tej zaum yuav muaj teeb meem nrog cov khoom siv tsis zoo lossis kev kho cua sov tsis raug.
Component Spectroscopic Analysis: Cov ntsiab lus ntawm cov ntsiab lus tseem ceeb yog kuaj pom siv lub xov tooj X-ray fluorescence spectrometer, xws li chromium (Cr) Ntau dua lossis sib npaug li 8%, molybdenum (Mo) Ntau dua lossis sib npaug li 0.5%, thiab manganese (Mn) Ntau dua lossis sib npaug li 1.5%. Cov ntsiab lus no txhim kho qhov hnav tsis kam thiab kev cuam tshuam ntawm cov hlau.
Metallographic Observation: Tom qab sampling, soj ntsuam nyob rau hauv ib lub microscope. Siab- cov ntaub ntawv zoo yuav tsum muaj cov qauv tempered martensite + dispersed carbide qauv. Yog hais tias lub network carbides los yog grain ciam ciam sib cais tshwm sim, cov khoom yog nquag nkig tawg thiab muaj lub neej luv luv.
Txheej Txheem Kev Kho Hniav: Saib xyuas seb cov hlau saum npoo puas tau raug txhaj tshuaj tiv thaiv thiab tiv thaiv- txheej txheej. Qhov no zoo tiv thaiv corrosion thaum ntxov thaum lub sij hawm thauj mus los thiab siv, ncua nws lub neej kev pab cuam.
