Tiv thaiv oxide zaj duab xis rau saum npoo ntawm cov khoom cua sov

(1) Nws tuaj yeem ua kom qeeb ntawm qhov permeation ntawm oxidizing roj hauv oxidizing nruab nrab thiab txo tus nqi ntawm alloy oxidation.

(2) Hauv cov xov xwm uas tsis yog oxidizing (xws li nitrogen, hydrogen, carburizing gas, sulfide, thiab lwm yam), maj mam txo cov roj nkag mus thiab txo qhov corrosion ntawm alloy.

(3) Nws tuaj yeem txo qhov volatilization poob ntawm hluav taws xob cua sov alloy Cheebtsam nyob rau hauv lub tshuab nqus tsev los yog tsis tshua muaj siab tej yam kev mob.Qhov kev tiv thaiv oxide zaj duab xis yog ib tug barrier los tiv thaiv carburization ntawm hluav taws xob cua sov ntsiab. Thaum cov oxide zaj duab xis puas lawm, cov roj txo yuav nkag mus rau hauv cov hlau los ntawm kev puas tsuaj thiab carburize. Lub affinity ntawm chromium, hlau thiab carbon nyob rau hauv hluav taws xob cua sov alloys muaj zog heev, thaum txhuas, silicon, npib tsib xee, thiab lwm yam yog tsis muaj zog heev. Yog li ntawd, thaum cov roj carburizing tiv tauj cov hlau, cov tshuaj tom qab carburizing yuav tshwm sim.

Cov khoom tseem ceeb ntawm kev tiv thaiv oxide zaj duab xis ntawm hluav taws xob cua sov alloy yog: Cr2O3, NiO, Fe2O3 rau nickel-chromium thiab nickel-chromium-hlau alloys, thiab Al2O3, Cr2O3 rau hlau-chromium-aluminium alloys. Cov oxides no muaj qhov kub thiab txias hauv qhov muaj zog txo cov pa roj carbon monoxide. Nws txiav txim siab lub zog ntawm alloy lub carburization kuj.

Thaum qhov kub thiab txias, tom qab hluav taws xob cua kub cua tiv tauj cov pa roj carbon monoxide, cov yeeb yaj kiab tiv thaiv oxide yuav raug rhuav tshem, thiab tom qab ntawd cov pa roj carbon monoxide yuav nkag mus rau hauv cov hlau los ua cov tshuaj tiv thaiv carburizing. Cov tsim carbides yuav ua rau cov nqi ntawm cov hlau tsis kam nce, cov yas kom txo qis, cov tawv nqaij tawm, thiab thaum kawg cov cua sov ua tsis tau sai.

Kev ua tau zoo thiab kev siv mica hluav taws xob cua sov coil:

1. Cov yam ntxwv ntawm cov khoom: Nws muaj qhov zoo ntawm kev ua haujlwm yooj yim, txhim khu kev qha, kev siv yooj yim, kub ceev, siab thermal efficiency, tsawg zog noj, kev pab lub neej ntev, thiab ntau lawm tsis txwv los ntawm tus qauv thiab loj.

2. Khoom siv: dav siv hauv tshuab yas, ntim thiab luam ntawv, petrochemical, khoom siv hluav taws xob thiab lwm yam lag luam.

3. Lub nplhaib mica hluav taws xob cua sov siv lub phaj steel hlau tsis zoo li lub plhaub sab nraud, thiab cov rwb thaiv tsev siab thiab kub-resistant mica phaj raws li cov tub ntxhais. Cov nickel-chromium alloy tsis kam xaim ntawm ntau yam kev qhia tshwj xeeb yog qhov sib npaug ntawm qhov cua sov, thiab ua tiav rau ntau hom los ntawm kev tsim cov tshuab. Xav tau lub cev. tuaj yeem txuas tau raws li cov neeg siv xav tau. Sab nraud tshav kub dissipation nto yog nruab nrog cov khoom txuag hluav taws xob, thiab sab hauv tshav kub dissipation nto yog sintered nrog infrared rays, uas tuaj yeem txuag hluav taws xob. Stainless hlau mica hluav taws xob cua sov coil muaj specifications xws li lub nplhaib hom thiab phaj hom.
