Hnav resistant steel phaj

Hnav cov kav dej tiv thaiv steel yog tsim ntawm cov roj carbon hlau tsawg thiab tagnrho hnav-resistant txheej.Lub alloy hnav-resistant txheej feem ntau yog 1/3 ~ 1/2 ntawm tag nrho cov tuab.Thaum lub sijhawm ua haujlwm, cov matrix muab cov khoom zoo xws li lub zog, toughness thiab plasticity los tiv thaiv sab nraud quab yuam, thiab cov hlau hnav-resistant txheej muab cov khoom hnav-tiv taus uas ua tau raws li cov kev cai ntawm kev ua haujlwm.

Cov hnav-resistant steel phaj yog xim hlau sib khi ntawm lub alloy hnav-resistant txheej thiab lub substrate.Los ntawm cov khoom tshwj xeeb thiab tsis siv neeg vuam txheej txheem, lub siab hardness tus kheej tiv thaiv alloy vuam hlau yog tusyees welded ntawm substrate.Tus naj npawb ntawm cov txheej txheem sib xyaw yog ib qho mus rau ob lossis txawm tias muaj ntau txheej.Thaum lub sij hawm cov txheej txheem sib xyaw, cov kev tawg sib nraus tshwm sim vim muaj sib txawv shrinkage piv, uas yog qhov zoo tshaj plaws ntawm kev hnav-resistant steel phaj.

Lub alloy hnav-resistant txheej yog tsuas yog tsim ntawm chromium alloy xws li manganbdenum, molybenum, niobium thiab npib tsib xee kuj ntxiv.Tus carbides hauv daim hlau metallographic cov qauv tau faib rau cov duab fiber ntau, thiab cov kev taw qhia fiber ntau sib tshuam nrog nto.Lub micro nyuaj ntawm carbide tuaj yeem ncav cuag saum toj HV1700-2000 thiab hardness tuaj yeem ncav cuag HRC58-62.Alloy carbides muaj cov muaj zog ruaj khov ntawm qhov kub thiab txias, tswj lub siab tawv, thiab muaj oxidation zoo tsis kam.Lawv tuaj yeem siv tau ib txwm nyob hauv 500 ℃.

Cov ris-resistant txheej yuav siv daim ntawv ntawm nqaim channel (2.5-3.5mm), dav channel (8-12 hli), nkhaus (s, etc;Nws yog tsuas yog tsim ntawm chromium alloy thiab lwm yam txheej txheem alloy xws li manganbdenum, niobium, npib tsib xee thiab boron.Tus carbides hauv daim hlau metallographic cov qauv tau faib rau cov duab fiber ntau, thiab cov kev taw qhia fiber ntau sib tshuam nrog nto.Cov ntsiab lus carbide yog 40-60%, microhardness tuaj yeem ncav cuag ntau dua HV1700, thiab lub hardness tuaj yeem ncav cuag HRC58-62.

Scope ntawm daim ntawv thov

Hnav Cov Tiv Thaiv Hlau Hlau muaj lub siab ua haujlwm tiv taus thiab kev ua tau zoo.Nws tuaj yeem txiav, khoov thiab welded.Nws tuaj yeem sib txuas nrog lwm cov qauv los ntawm vuam, plug vuam thiab bolt kev txuas.Nws yog lub sijhawm-txuag thiab yooj yim nyob rau hauv tus txheej txheem ntawm kev saib xyuas.Nws yog dav siv hauv metallurgy, thee, cement, hluav taws xob fais fab, iav, mining, cov ntaub ntawv hauv tsev, cib thiab pobzeb thiab lwm yam lag luam.Piv nrog rau lwm cov ntaub ntawv, nws muaj tus nqi tsim nuj nqis, nws tau nyiam los ntawm ntau thiab ntau kev lag luam thiab cov tuam ntxhab.
