Kev lag luam mining xav tau cov khoom siv uas tuaj yeem tiv taus qhov hnyav, muaj kev cuam tshuam loj, thiab kev puas tsuaj tas mus li. Lub zog siab alloy steel castings muab cov kav ntev thiab kev ntseeg siab uas yuav tsum tau siv rau cov khoom siv mining tseem ceeb xws li tsheb thav duab thiab crusher hnav qhov chaw. Tsis zoo li cov qauv carbon steel, alloy steel sib txuas cov ntsiab lus xws li manganese, chromium, molybdenum, thiab nickel los txhim kho hardenability, toughness, thiab hnav tsis kam. Cov khoom no ua rau alloy steel castings qhov kev xaiv zoo tshaj plaws rau cov kev thov mining tshaj plaws.
Mining tsheb thav duab yuav tsum txhawb nqa loj heev thaum lub sij hawm ua kom muaj zog sib tw, kev co, thiab kev poob siab los ntawm cov av ntxhib. High zog alloy steel castings yog siv rau cov thav duab tseem ceeb xws li cov ntoo khaub lig, ncua kev kawm mounts, thiab pivot pob qij txha. Cov txheej txheem casting tso cai rau engineers tsim cov geometries nyuaj nrog cov hlua txuas ntxiv thiab maj mam hloov cov thickness uas yuav nyuaj los yog kim kom ua tiav los ntawm kev tsim khoom. Los ntawm kev siv cov qib steel hlau xws li 30CrMo lossis 35CrMo, cov tuam txhab ua tiav tensile zog tshaj 100,000 psi nrog rau qhov kub thiab txias zoo heev. Cam khwb cia thav duab kuj tshem tawm weld seams uas tuaj yeem ua cov ntsiab lus tsis ua haujlwm nyob rau hauv kev thauj khoom cyclic.
Crusher hnav qhov chaw ntsib qhov kev sib tw sib txawv: kev puas tsuaj loj thiab muaj zog compressive siab. Mantles, tais liners, lub puab tsaig phaj, thiab tshuab tuav yuav tsum tiv thaiv gouging thiab yaig los ntawm cov pob zeb tawv thiab ore. High zog alloy steel castings nrog ntxiv chromium los yog manganese ua hauj lwm hardening nto uas ua nyuaj nyob rau hauv kev cuam tshuam. Hadfield manganese steel, piv txwv li, pib nrog cov hardness me ntsis tab sis sai hardens thaum muaj kev cuam tshuam thaum tuav cov tub ntxhais tawv. Qhov kev coj cwj pwm tshwj xeeb no tsuas yog ua tiav los ntawm precision casting. Ib yam li ntawd, siab chromium alloy steel castings muab zoo heev tiv thaiv zawv zawg abrasion, ua rau lawv zoo tagnrho rau lub khob hliav qab crusher liners thiab cuam tshuam crusher rauj.
Thaum xaiv ib tus neeg muag khoom rau cov mining castings, cov neeg yuav khoom yuav tsum xyuas kom meej tias qhov chaw tsim khoom ua raws li kev tswj hwm nruj nrog rau kev tshuaj xyuas tshuaj, kev sim tshuab, thiab kev tshuaj xyuas tsis muaj kev puas tsuaj xws li sib nqus particle lossis kuaj ultrasonic. Cov txheej txheem kev kho cua sov zoo li quenching thiab tempering yuav tsum tau tswj hwm kom ua tiav qhov kev sib tw hardness thiab toughness.
Txawm hais tias koj xav tau lub tsheb thauj khoom rugged los yog lub sijhawm ntev crusher mantle, siab zog alloy steel castings muab cov kev ua tau zoo thiab kev pabcuam lub neej uas cov haujlwm mining yuav tsum tau txo qis qis thiab txo tus nqi ntawm cov tswv cuab.
