Ua kua shrinkage thiab solidification shrinkage ntawm alloy flanges

Nyob rau hauv zus tau tej cov alloy flanges, cov kua shrinkage thiab solidification shrinkage ntawm lub alloy yog manifested raws li lub ntim txo ntawm cov alloy, uas feem ntau yog qhia los ntawm lub ntim shrinkage tus nqi. Lawv yog cov laj thawj tseem ceeb rau qhov shrinkage kab noj hniav thiab shrinkage defects ntawm casting. Txawm hais tias cov khoom hauv lub xeev shrinkage ntawm cov hlau tseem yog qhov hloov pauv, nws tsuas yog ua rau muaj kev hloov pauv ntawm qhov ntev ntawm cov casting. Yog li ntawd, nws yog feem ntau qhia los ntawm linear shrinkage tus nqi. Cov khoom hauv lub xeev shrinkage yog lub hauv paus ua rau tsis xws luag xws li kev ntxhov siab sab hauv, deformation thiab tawg hauv castings. Tsawg-carbon steel flanges muaj cov yas zoo thiab tsis muaj zog. Tom qab ntxiv qhov tsim nyog ntawm cov ntsiab lus carbon, lawv yuav nyuaj, thiab cov yas yuav txo qis thiab lub zog yuav nce. Alloy flange kev sib txuas yuav tsum tau tiv taus siab tensile, compressive, torsional, thiab shear zog. Loj flanges yog qhov kev xaiv zoo dua.

Kev siv cov yam ntxwv ntawm alloy flanges

Alloy flange yog cov khoom sib txuas ntawm ob txoj kab uas hla loj, feem ntau yog ob lub flange daim ntxiv rau ib tug xov tooj ntawm fastening bolts, alloy flange yog steel flange. Alloy flanges yog siv rau cov kav dej thiab cov kav dej uas muaj cov yam ntxwv tshwj xeeb, thiab feem ntau yog siv rau hauv qhov kub thiab txias qhov chaw. Cov khoom siv yog 12Cr1MoV, 15CrMo, P91, P22, 10CrMo910 thiab lwm yam.

5 yam ntxwv ntawm kev kub siab flanges

1. Lub hauv paus ntsiab lus sealing belongs rau yas deformation

2, txuas nrog bolts

3. Bolts yuav tsum muaj lub zog tensile, qhov kub thiab txias qhov sib txawv, thiab dais dabtsi yog khoov lub sijhawm, torque thiab ntau lwm yam kev ntxhov siab.

4. Loj loj, hnyav hnyav, nyuaj rau nruab thiab nrhiav.

5. Lub sealing kev ua tau zoo tsis ruaj khov, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej hnyav (qhov kub thiab txias, kev kub siab, thiab cov xov xwm muaj kuab lom heev), uas tuaj yeem ua rau xau thiab ua rau muaj qhov tshwm sim loj.
