Muaj plaub hom kev siv kub rau hluav taws xob cua sov alloys

1. Ultra siab kub hluav taws xob cua sov alloy

Kev khiav hauj lwm kub ntawm ultra-siab kub hluav taws xob cua sov alloy yog 1400 degree. Nws yog siv los tsim hluav taws xob cua sov cov ntsiab lus rau cov cua kub cua sov nrog kev ua haujlwm kub ntawm 1200 txog 1300 degree. Cov tshuaj muaj pes tsawg leeg ntawm no alloy belongs rau hlau chromium aluminium series. Txhawm rau kom ntseeg tau tias qhov kev ua tau zoo ntawm cov alloy ntawm qhov kub thiab txias, pawg no ntawm cov alloys muaj cov qib siab ntawm chromium thiab txhuas. Ntawm lawv, chromium yog 22% ~ 28%, txhuas yog 6% ~ 8%, thiab kuj tseem muaj me me ntawm cobalt, molybdenum, niobium, titanium, thiab cov lej ntawm cov khoom xws li yttrium, lanthanum, thiab cerium. Cov pab pawg no muaj xws li steel billets ua los ntawm hmoov metallurgy, hluav taws xob cua sov alloy hlau thiab strips ua tiav thiab tsim.

Ultra siab kub hluav taws xob cua sov alloys yog tsuas yog siv rau hluav taws xob cua sov Cheebtsam nyob rau hauv ib tug siv lead ua diffusion furnaces, hmoov metallurgy khoom sintering furnaces, ceramic calcination furnaces, thiab high-kub kub kho rauv nrog ua hauj lwm kub xws li ntawm 1200 mus rau 1300 degree.

Cov qib hluav taws xob cua sov alloy uas muaj nyob rau hauv chav kawm kub siab tshaj plaws suav nrog: 0Cr26Al7.5; 0Cr27Al7Mo2, 0Cr24Al6R, 0Cr22Al6CoRe, thiab 0Cr22Al5.8 thiab 0Cr23Al6 refined los ntawm hmoov metallurgy.

2. High kub qib hluav taws xob cua sov alloy

Kev siv kub ntawm qib high-kub hluav taws xob cua sov alloy yog 1300 degree, feem ntau yog siv rau kev tsim kub ntawm 1100 ~ 1200 degree

Hluav taws xob cua sov ntsiab lus rau cua sov rauv taws. Cov pab pawg no ntawm hluav taws xob cua sov alloys kuj belongs rau cov hlau chromium aluminium series. Cov ntsiab lus chromium thiab txhuas hauv qhov sib xyaw ua ke ntawm kub no yog qis dua li ntawm cov qib siab qib siab alloys, nrog cov ntsiab lus chromium xws li 22% mus rau 25% thiab cov ntsiab lus txhuas ntawm 4% mus rau 6%. Nws kuj muaj me me ntawm molybdenum, niobium, cobalt, titanium, thiab cov ntsiab lus tsis tshua muaj hauv ntiaj teb.

High kub qib hluav taws xob cua sov alloys yog tsuas yog siv rau kev tsim hluav taws xob cua sov Cheebtsam rau cov cua sov kho rauv xws li quenching, normalizing, annealing, thiab tshuaj kho, nrog rau cov hluav taws xob cua sov Cheebtsam rau melting furnaces ntawm tooj liab, txhuas, thiab lawv alloys.

Cov qib ntawm high-temperature hluav taws xob cua sov alloys muaj xws li 0Cr25Al5, 0Cr21Al6Nb, 0Cr23Al6, thiab lwm yam.

3. Nruab nrab kub hluav taws xob cua sov alloy

Qhov nruab nrab kub hluav taws xob cua sov alloy yog siv ntawm qhov kub ntawm 1100 degree thiab feem ntau yog siv rau kev tsim hluav taws xob cua sov Cheebtsam rau cov cua sov rau cov cua sov uas ua haujlwm kub ntawm 850 txog 95{ {17}} degree , xws li cov cua kub cua kub cua sov, aluminium melting furnaces, thiab cov khoom siv hauv tsev. Cov pab pawg no ntawm cov hluav taws xob cua sov alloys muaj cov yas zoo thiab tuaj yeem ua tiav rau hauv cov khoom siv hluav taws xob ua kom sov hauv chav sov. Cov qib electrothermal alloy uas muaj nyob rau hauv pawg no suav nrog: nickel chromium alloy Cr30Ni70; Cr20Ni80, hlau chromium txhuas series alloys 0Cr23Al5, 0Cr20Al3, 0Cr19Al5, 0Cr21Al6, thiab lwm yam.

4. Tsawg kub qib hluav taws xob cua sov alloy

Kev siv kub ntawm cov cua kub cua kub qis qis qis qis dua 95{14}} degree, feem ntau yog siv rau kev tsim hluav taws xob cua sov cov ntsiab lus rau cov cua kub cua sov uas ua haujlwm kub hauv qab 800 ~ 750 degree, xws li cov cua kub cua sov, cua sov kom qhuav. , thiab cov khoom siv hauv tsev. Cov hluav taws xob cua sov alloys uas muaj nyob rau hauv pawg no suav nrog Cr15Ni60, Cr20Ni35, Cr20Ni25 alloys hauv cov nickel chromium series, thiab 1Cr13Al4, 0Cr19Al3 alloys hauv cov hlau chromium aluminium series.
