Xaiv txoj cai kub resistant steel castings yuav tsum muaj kev xav txog nws cov kev ua tau zoo xav tau ntawm kev ua haujlwm hloov ua haujlwm. Nov yog qee cov kev xaiv yooj yim:
Tsawg tshaj ntu (300 degree -600 degree)
Rau qhov ntsuas kub no, qis alloy tshav kub-resistant steel castings tuaj yeem xaiv cov thermal muaj zog thiab oxidation tsis kam ntawm cov hlau rau ib qho. Lawv muaj tsawg nyob rau hauv nqe thiab yig, thiab yog dav siv nyob rau hauv cov khoom cua kub kev lag luam dav dav, kev sib pauv cua sov, thiab lwm yam.
Nruab nrab ntu (600 degree -800 degree)
Thaum kev ua haujlwm kub yog nruab nrab ntawm 600 degree thiab 800 degree, siab siab Austenitic kub-resistant steel-resistant steel kis, xws li 310s (06cr25Ni20), tuaj yeem txiav txim siab. Cov ntaub ntawv no muaj lub zog zoo tshaj plaws, oxidation tsis kam, tuaj yeem ua haujlwm nyob rau hauv nruab nrab thiab ntau siv hluav taws xob leeg, thiab lwm yam.
Cov hlau hluav taws kub ferritic-resistant steel castings xws li 0 cr13 yog qhov haum rau qhov ntsuas kub no. Lawv muaj oxidation zoo tsis kam thiab tiv thaiv cov khoom siv los tiv thaiv kab mob, thiab cov khoom lag luam thermal me me, uas tau zoo nyob rau qee lub sijhawm uas muaj kev ruaj khov nyob hauv qee lub sab nraud.
Qhov kub siab ntu (saum toj no 800 degree)
Rau qhov kub kub nyob ib puag ncig saum 800 degree, feem ntau nws yog qhov tsim nyog los xaiv cov khoom tshwj xeeb kub-resistant steel castings xws li alloys lossis cobalt-based alloys. Piv txwv li, nickel-raws li alloys xws li Inconel 600 thiab Inconel Distance, oxidation siab ib puag ncig xws li aerospace thiab roj turbines.
Cobalt-raws li cov alloys muaj xws li cov txheej txheem stellite uas yuav tsum muaj cov khoom siv kub heev, xws li cov roj muaj cua sov, ntsaws ruaj ruaj, thiab lwm yam.
Thaum ua qhov kev xaiv tiag tiag, nws tseem tsim nyog los ua kev ntsuam xyuas kev nkag siab zoo ntawm qee yam xws li kev ua haujlwm ua haujlwm tshwj xeeb, thiab kev pabcuam lub neej. Yog tias tsim nyog, koj tuaj yeem sab laj tus kws tshaj lij lossis xa mus rau cov phau ntawv qhia thiab cov qauv kev ua haujlwm.
Yog tias koj xav tau cov khoom cua kub zoo tiv thaiv, thov hu rau Philloy nrog cov lus nug ntxiv.
