High-zoo hnav-resistant rauj taub hau feem ntau yog ua los ntawm high-chromium cam khwb cia hlau txuam alloys.
Tam sim no, cov khoom siv feem ntau siv rau lub taub hau-resistant rauj yog high-chromium cam khwb cia hlau. High-chromium alloy rauj taub hau muaj qhov nyuaj tshaj plaws thiab yog cov khoom siv zoo hnav-tiv taus. Lawv tau siv dav hauv rauj crushers. Tom qab kev kho cua sov, qhov nyuaj ntawm high-chromium cam khwb cia hlau tuaj yeem ncav cuag ntau dua 58HRC. Lub matrix yog high-hardness martensite thiab cov qauv muaj ib tug loj npaum li cas ntawm high-hardness carbide M7C3. Nws yog suav hais tias yog ib qho zoo tagnrho hnav-resistant khoom rau crusher rauj taub hau. Cov qauv thiab kev ua tau zoo ntawm lub taub hau-resistant rauj feem ntau yog nyob ntawm cov ntsiab lus ntawm chromium, carbon, thiab manganese. Txij li cov affinity ntawm carbon thiab chromium yog ntau dua li affinity ntawm hlau thiab carbon, ib tug series ntawm ruaj khov ferrochromium tebchaw yog tsim.
High chromium alloy yog cov khoom hnav-tiv taus nrog cov khoom tiv thaiv zoo heev, tab sis nws cov tawv nqaij yog qhov tsawg thiab nws yuav ua rau tawg tawg. Txhawm rau kom muaj kev nyab xeeb ntawm kev ua haujlwm ntawm high-chromium hnav-tiv taus rauj taub hau, feem ntau siv rauj taub hau sib xyaw. Ib qho yog siv qhov loj-qhov loj rauj kov los txhawb lub siab-chromium rauj lub taub hau, thiab lub toughness ntawm rauj kov txhawb lub zog loj heev thaum lub sij hawm crushing txheej txheem. Ib qho yog ob-kua thermal composite rauj taub hau. Cov khoom siv no siv cov khoom sib txawv ntawm kev sib xyaw ua ke ntawm chromium, molybdenum, tooj liab, npib tsib xee, vanadium, titanium thiab lwm yam alloys thiab cov txheej txheem tsim khoom nruj thiab tshwj xeeb. Nws muab cov kev hnav zoo heev thiab kev kub siab ua haujlwm ntawm high-chromium alloy casting. Oxygen tsis kam, thermal qaug zog tiv thaiv (los yog corrosion kuj) yog kev sib xyaw nrog cov zoo toughness thiab processability ntawm cam khwb cia hlau, thiab nws muaj zoo heev hnav tsis kam thiab cuam tshuam tsis kam uas nyuaj rau ua tiav nrog ib tug hlau khoom.
Cov ntsiab lus tseem ceeb rau kev ua kom zoo hnav-tiv taus rauj taub hau:
1. Xav los ntawm tus neeg siv khoom qhov kev xav, txheeb xyuas qhov sib xyaw thiab silicon cov ntsiab lus ntawm cov ntaub ntawv yuav tsum tau crushed, thiab kho qhov sib piv ntawm alloy kom txhua lub taub hau rauj yog customized rau cov neeg siv khoom; peb lub tuam txhab cov lus hais yog: Tsuas yog qhov yog, Qhov ntawd yog qhov tseem ceeb.
2. Peb lub tuam txhab tau poob ua npuas ncauj casting rauj taub hau tshuab thiab muaj kev tswj xyuas zoo ntawm cov khoom tiav kom ntseeg tau tias txhua lub taub hau rauj xa tuaj rau koj yog tsim nyog thiab nws qhov, grooves thiab qhov chaw tau raug ntxuav, txuag lub sij hawm installation. , thaum txo cov nqi zog.
Cov txheej txheem kev kho cua sov nruj rau hnav-tiv taus rauj taub hau
Peb lub tuam txhab hnav-resistant rauj taub hau undergoes nruj kev kho cua sov. Nws yog rhuab mus rau 1100 degree thiab ua kom sov ua ntej tso tawm ntawm lub qhov cub. Tom qab kev kho tshuaj lom neeg nrog cov kua quenching (lub hardness yog heev nce), nws yog ces raug mus rau low-temperature tempering ntawm 600 degree, thiab ces cua-txias tom qab tawm ntawm lub cub tawg. Lub hardness tuaj yeem ncav cuag 60HRC. Cov txheej txheem yog mature. , peb muaj cov kev xav tau siab heev ntawm hardness thiab toughness ntawm lub taub hau rauj, thiab nws yog peb lub luag haujlwm los ua lub luag haujlwm rau peb cov neeg siv khoom.
