SPV490Q Steel Boiler Phaj Thaum Tshav Kub Kho Ua Ntej
1, SPV490Q siab rau cov phaj tsim los ntawm kev ua kom muaj zog thiab cov txheej txheem sib txuam, kom ua tiav lub zog txuag thiab txo tus nqi txo cov hom phiaj.
2, ncaj qha ntawm cov hlau phaj tempering zog poob yog qhov me me, txhim kho kev nruj me ntsis yog pom tseeb; Rov ua dua cov hlau txiav steel ua rau kev kub siab, lub zog yuav yog qhov poob qis. Tougness thiab cov vanityity txhim kho, tus qub muaj zoo dua tempering tiv thaiv.
3, Ncaj Ncees Kom Tau Txais Lub Siab Txom Nyem Laij Martitic Lub Koom Haum, nws cov martensitic lath khoov thiab hla ib leeg. Rov ua dua cov hlau txiav kom tau txais qis qis Dislocation Density Martensite lub koom haum, Martite slats thicker.
4, nyob rau tib lub tempering tej yam kev mob, ncaj qha quenched steel phaj nag lossis daus quenched steel phaj nag lossis daus ntau dua ntxhib.
