Luv luv ntawm kev piav caij nplooj ntoos hlav hlau hlau yuav tsum tau ua

Caij nplooj ntoos hlav hlau Lub caij nplooj ntoos hlav Cov cai ntawm lub caij nplooj ntoos hlav steel hlau kev kawm. Caij nplooj ntoos hlav nyob rau hauv kev cuam tshuam, kev co los yog ntev siv kev nyuab siab, yog li qhov yuav tsum tau ntawm lub caij nplooj ntoos hlav steel hlau nrog high tensile lub zog, elastic txwv, high qaug zog lub zog. Nyob rau hauv tus txheej txheem yuav tsum tau ib lub caij nplooj ntoos hlav steel hlau hardenability, yooj yim decarburization, deg zoo thiab yog li on. Carbon caij nplooj ntoos hlav steel hlau uas yog cov ntsiab lus ntawm cov dej hauv WC hauv qhov ntau ntawm 0.6% -0.9% high-quality carbon steel hlau. Alloy caij nplooj ntoos hlav steel hlau yog tsuas yog silicon thiab manganese hlau, lawv cov ntsiab lus yog me ntsis qis dua, ua tau los ntawm cov ntsiab lus silicon Wsi los txhim kho kev kawm; ntxiv rau Ge, tungsten, vanadium alloy caij nplooj ntoos hlav xaim. Nyob rau xyoo tas los no, tag nrho nrog Suav teb cov kev pab cuam, thiab raws li cov kev cai ntawm cov cuab yeej tshiab rau tsheb thiab tsheb laij teb tsim, cov hlau tshiab xws li boron, niobium thiab molybdenum tau raug tsim los ntawm cov pob zeb ntawm silicon-manganese hlau mus cuag kev pab cuam lub neej ntawm caij nplooj ntoos hlav thiab txhim kho lub caij nplooj ntoo hlav zoo Lub

Kev yuav tsum ua:

Caij nplooj ntoos hlav hlau hlau Caij nplooj ntoos hlav nyob rau hauv kev cuam tshuam, kev co los yog kev siv ntev ntawm kev nyuab siab, yog li qhov yuav tsum tau ntawm lub caij nplooj ntoos hlav steel hlau nrog high tensile lub zog, elastic txwv, siab qaug zog lub zog. Nyob rau hauv tus txheej txheem ntawm lub caij nplooj ntoos hlav xaim hlau muaj ib yam hardenability, yooj yim decarburization, zoo deg zoo thiab lwm yam carbon caij nplooj ntoos hlav steel hlau uas yog cov ntsiab lus ntawm WC hauv qhov ntau ntawm 0.6% -0.9% zoo carbon steel hlau. Alloy caij nplooj ntoos hlav steel hlau yog tsuas yog silicon thiab manganese hlau, lawv cov ntsiab lus yog me ntsis qis dua, ua tau los ntawm cov ntsiab lus silicon Wsi los txhim kho kev kawm; nyob rau hauv tas li ntawd mus rau Ge, tungsten, vanadium alloy caij nplooj ntoos hlav steel hlau. Nyob rau xyoo tas los no, tag nrho nrog Suav teb cov kev pab cuam, thiab raws li cov kev cai ntawm cov cuab yeej tshiab rau tsheb thiab tsheb laij teb tsim, cov hlau tshiab xws li boron, niobium thiab molybdenum tau raug tsim los ntawm kev sib xyaw silicon-manganese hlau kom ntev kev pab cuam lub neej ntawm caij nplooj ntoos hlav thiab txhim kho lub caij nplooj ntoo hlav zoo Lub

Lub caij nplooj ntoos hlav dav dav hluav taws xob yuav siv hluav taws xob rau hluav taws xob, lub tshuab ua kom sov lossis cov pa oxygen ntau lawm; zoo zoo los yog muaj cov khoom tshwj xeeb zoo ntawm lub caij nplooj ntoos hlav hlau zoo hlau, nrog lub tshuab hluav taws xob lossis lub tshuab nqus tsev nqus dej. Caij nplooj ntoos hlav hlau hlau nyob hauv cov pa, manganese, silicon thiab lwm qhov tseem ceeb ntawm cov kev cai ntawm ib qho chaw nqaim, yuav tsum yog cov tshuaj tua kab nruj nruj. Silicon ntsiab lus yog siab thaum tsim ntawm npuas thiab lwm yam teeb meem, steel bar forging tom qab dov tsis yog yooj yim los tsim dawb me ntsis. Yog li ntawd, lub smelting ntawm raw cov ntaub ntawv yuav tsum qhuav, sim tshem tawm cov roj thiab inclusions, tab sis kuj kom tsis txhob overheating ntawm molten hlau.

Caij nplooj ntoos hlav hlau hlau Caij nplooj ntoos hlav steel hlau nyob rau hauv lub ntxuag ua kom them nyiaj tshwj xeeb kom zoo rau decarburization thiab deg zoo. Hlau deg loj decarburization, yuav ua rau txo qis qis ntawm cov hlau. Rau siab silicon caij nplooj ntoos hlav xaim xws li 70Si3MnA, kev saib xyuas yuav tsum tau noj kom tsis txhob muaj graphitization. Yog li, qhov ntsuas kub thaum lub caij ua haujlwm kub tsis txaus (≥ 850 ℃), kom tsis txhob muaj lub graphitization yooj yim rau qhov kub thiab txias (650 ~ 800 ℃) nyob ntev.

Tom qab lub caij nplooj ntoos hlav tsim los ntawm kev tua peening, lub caij nplooj ntoos hlav ntim yuav tsim tau qhov seem ntawm kev nyuab siab rau kev chim siab rau qhov feem ntawm txoj kev ntxhov siab ua haujlwm ntawm txheej txheej, inhibit qhov tsim ntawm cov kab tawg, uas tuaj yeem txhim kho qis tshaj ntawm lub caij nplooj ntoos hlav.
