Cov ntaub ntawv ntawm cov blocks ntxig feem ntau yog suav nrog cov pa roj carbon hlau zoo, cov hlau Allolo thiab Stainless hlau.
◆ Cov pa roj carbon hlau siab zoo
Cov hlau zoo xws li 35, 45, 50, thiab lwm yam yog siv nyob rau hauv cov khoom xaiv ntawm shaftts vim lawv cov cuab yeej siv tshuab ua tau zoo. Tom qab ib txwm ua los yog quenching, cov steels no tuaj yeem ua tau kom tau lub zog thiab lub zog ntawm cov hlau tshaj plaws.
◆ Cov hlau Alloy
Txawm hais tias alloy cov hlau xws li 40CRNI, 38CRMOA, thiab lwm yam yog kim, lawv txoj haujlwm tseem ceeb hauv kev tsim cov kev tsim khoom nrog cov cai tshwj xeeb. Tom qab kev kho mob tshwj xeeb, cov ntaub ntawv tau txhim kho saum npoo hardness thiab cov tub ntxhais lub zog, thiab haum rau cov shafts hauv qhov kub thiab txias, kev kub ceev thiab hnyav lub chaw ib puag ncig.
◆ Cov hlau nplaum
Stainless tus hlau xws li 430, 304 thiab 316 muaj kev txhim kho corrosion tsis zoo thiab qee lub zog. 430 STEEL yog yuav luag xeb-dawb, thiab 304 thiab 306 stainless hlau tsis yog sib nqus thiab haum rau cov av noo thiab qhov ntsuas kub.
