Raws li cov khoom tseem ceeb ntawm cov khoom siv thauj khoom, kev xaiv cov khoom siv rau scraper conveyor chains ncaj qha cuam tshuam rau cov cuab yeej ua haujlwm ruaj khov, kev pabcuam lub neej, thiab cov nqi tu.
Alloy Steel Chains
Los ntawm cov txheej txheem kho cua sov-xws li quenching thiab tempering- qhov tawv tawv tuaj yeem ncav cuag HRC 45–55, muab kev hnav tsis kam uas yog 3 txog 5 npaug ntau dua li cov pa roj carbon zoo tib yam. Nrog rau lub zog tensile ib txwm muaj ntau dua lossis sib npaug li 800 MPa, cov saw hlau no muaj peev xwm tiv taus hnyav -cov haujlwm ua haujlwm (xws li cov pom hauv kev lag luam mining thiab cement).
Stainless hlau
Feem ntau siv 304 thiab 316L qib, cov khoom siv no muaj kev tiv thaiv corrosion zoo heev (nrog rau kev xeb txhua xyoo tsawg dua lossis sib npaug li 0.01 hli hauv ib puag ncig nrog pH ntawm 6-8). Txawm li cas los xij, vim nws qhov qis qis dua (HRC Tsawg dua lossis sib npaug li 35), kev kho nitriding saum npoo yuav tsum tau txhim kho nws cov hnav tsis kam.
Carbon Steel Chains
Tus nqi qis (tus nqi kwv yees li ib - thib peb ntawm cov hlau alloy) thiab yooj yim rau txheej txheem; Txawm li cas los xij, lawv lub zog tensile tsuas yog 400-600 MPa, thiab lawv cov hnav tsis kam yog qhov tsis zoo.
