High-temperature caij nplooj ntoos hlav Pogo Pin
Cov qauv tau txais los ntawm high-temperature tempering ntawm high-temperature caij nplooj ntoos hlav yog tempered sorbate. Kev kho cua sov ua ke nrog quenching thiab high-temperature tempering yog ib txwm hu ua quenching thiab tempering kev kho mob los txhim kho lub zog, hardness, plasticity, thiab toughness ntawm lub caij nplooj ntoos hlav. Tempering kub yog 500-680 ℃, thiab cov qauv sorbate tau txais tom qab tempering. quenching + high-temperature tempering yog hu ua quenching thiab tempering kev kho mob, uas tuaj yeem tau txais cov khoom siv zoo nrog lub zog zoo, plasticity, thiab toughness. Nyob rau tib lub sijhawm, nws tuaj yeem ua rau qee cov hlau alloy siab (xws li cov hlau kub ceev) nrog cov nyhuv hardening theem nrab hardening. Nws qhov tsis zoo Ntawd yog, cov txheej txheem nyuaj dua, thiab lub zog yuav txo qis thaum txhim kho cov plasticity thiab toughness.
Kev kho cua sov tam sim no tuaj yeem siv rau qee qhov chaw los hloov quenching thiab tempering kev kho mob, ductile hlau austempering hloov 45 steel quenching thiab tempering (Ceeb toom: deformation kub kho: Tom qab cov hlau yog rhuab thiab austenitized tib lub sij hawm, nws yog ceev ceev txias rau. Qhov kub thiab txias, thaum nws tsis tau decomposed thiab hloov, ua ib tug kuj loj npaum li cas ntawm cov yas deformation, thiab ces quench thiab temper thaum nws tseem austenite kom tau tempered martensite.Qhov no thermal deformation txheej txheem txuas ntxiv. Cov txheej txheem ua ke ntawm quenching thiab tempering kev kho mob, piv nrog ib txwm quenching thiab tempering, tuaj yeem ua tiav lub zog ntau dua ntawm tib theem ntawm ductility thiab toughness). Cov khoom caij nplooj ntoos hlav tau tempered ntawm qhov kub thiab txias kom tau txais cov khoom muaj zog, elastic txwv, thiab siab toughness. Yog li ntawd, nws yog dav siv nyob rau hauv cov txheej txheem tseem ceeb ntawm lub tsheb, tsheb laij teb, tshuab cuab yeej, thiab lwm yam, xws li txuas rods, bolts, gears, thiab shafts.
Cov hom high-temperature springs feem ntau muab faib ua high-temperature resistant compression springs, high-temperature resistant extension springs, high-temperature resistant torsion springs, high-temperature resistant pwm springs, high-temperature resistant disc springs, etc. ntawm high-temperature-resistant caij nplooj ntoos hlav feem ntau yog CrSi, CrV, Inconel high-temperature alloy khoom. Qhov pom zoo kub kub yog 400 ℃ ~ 650 ℃, thiab kub hauv qab 400 ℃ kuj tuaj yeem ua stainless hlau. Xaiv cov khoom tsim nyog raws li qhov yuav tsum tau siv.
1, T631J1 / T631 yog siv rau cov cua kub-resistant springs thiab springs nrog siab tensile zog tom qab kev kho cua sov;
2, 630 stainless hlau yog nag lossis daus, quenching, martensitic stainless hlau, thiab qib no muaj lub zog siab, hardness, thiab corrosion kuj. Tom qab kev kho cua sov, cov khoom siv kho tshuab ntawm cov khoom zoo tshaj plaws thiab tuaj yeem ncav cuag lub zog compressive txog li 1100-1300mpa. Cov qib no tsis tuaj yeem siv rau qhov kub siab tshaj 300 ° C (570F) lossis qis heev. Nws muaj kev tiv thaiv corrosion zoo rau cov cua thiab diluted acids lossis ntsev. Nws cov corrosion kuj yog tib yam li 304 thiab 430.
