Lub rooj vag thiab riser separator cais cov khoom seem xws li lub rooj vag casting thiab riser, ntws raws, thiab lwm yam tsis ua rau cov khoom puas. Nws yog tsuas yog siv rau grey hlau (FC), nodular cam khwb cia hlau (FCD), alloy cam khwb cia hlau, cam khwb cia hlau (tsawg carbon steel, siab manganese hlau, thiab lwm yam) thiab lwm yam castings, nrog rau kev ua haujlwm yooj yim. Hloov phau ntawv hammering los yog txiav nrog cov tshuab ua haujlwm tsis tsuas yog txhim kho kev ua haujlwm zoo thiab txo tus nqi ntawm cov castings, tab sis kuj tseem txhim kho qhov chaw ua haujlwm zoo. Yuav tsis muaj suab nrov lossis txaws tshwm sim los ntawm kev vibration ntawm hammering, tsuas yog lub suab ntawm cov neeg kho tshuab ua haujlwm, ua kom ntsiag to, nyab xeeb, ib puag ncig tus phooj ywg, thiab kev lom zem ua haujlwm ua qhov tseeb.
