Chilled cam khwb cia hlau yob feem ntau yog siv nyob rau hauv cov txheej txheem hlau dov, feem ntau nyob rau hauv dov thiab ua cov hlau, tsis-ferrous hlau thiab lwm yam ntaub ntawv hlau. Lawv feem ntau yog siv los ua cov khoom tseem ceeb ntawm dov mills los hloov cov duab thiab qhov loj ntawm lwm cov ntaub ntawv hlau los ntawm extrusion, ncab lossis nias cov txheej txheem, thiaj li ua tiav cov txheej txheem thiab tsim cov khoom.
Tshwj xeeb, chilled cam khwb cia hlau yob yog siv rau hauv cov nram qab no:
1. Hlau thiab steel smelting thiab dov: chilled cam khwb cia hlau rolls yog siv nyob rau hauv hlau thiab steel smelting thiab dov ntawm txhua yam hlau, xws li steel phaj, steel kav, steel strips thiab thiaj li nyob.
2. Non-ferrous hlau smelting thiab dov: chilled cam khwb cia hlau yob yog siv rau smelting thiab dov ntawm tooj liab, txhuas, magnesium thiab lwm yam non-ferrous hlau, xws li txhuas cov khoom, tooj liab phaj, thiab lwm yam.
3. Hlau ua thiab molding: chilled cam khwb cia hlau yob yog siv nyob rau hauv kev ua thiab molding ntawm ntau yam ntaub ntawv hlau, xws li hlau kav, tsheb qhov chaw, mechanical qhov chaw thiab lwm yam.
Chilled cam khwb cia hlau yob ua lub luag haujlwm tseem ceeb hauv kev lag luam hlau vim lawv cov hardness siab, hnav tsis kam thiab thermal qaug zog ua haujlwm, uas ua kom muaj txiaj ntsig zoo thiab ua tiav thiab dov cov ntaub ntawv.
Cov txheej txheem ntawm kev ua chilled cam khwb cia hlau yob:
1. Kev npaj cov khoom siv raw: txiav txim siab cov ntaub ntawv tsim nyog xws li quartz xuab zeb, graphite, ductile hlau, thiab lwm yam, thiab sib tov thiab yaj lawv raws li qhov sib piv.
2. Casting: Muab cov hlau melted rau hauv yob pwm kom nws tuaj yeem ua rau tag nrho cov pwm kab noj hniav. Nyob rau tib lub sijhawm, cov dej txias yog txhaj kom txias cov cam khwb cia yob sai thiab siv lub zog kom tswj tau qhov ceev.
3. Collimation: Cov cam khwb cia yob yog collimated mechanically lossis los ntawm kev kho cua sov kom lawv qhov ntev thiab cov duab raws li cov qauv tsim.
4. Trimming: Siv cov txheej txheem kho tshuab lossis thermal kho los txiav cov yob kom tshem tawm cov khoom tsis sib xws thiab qhov tsis xws luag.
5. Cold hardening treatment: Cold hardening yog tau los ntawm kev muab cov yob rau hauv ib qho chaw khov kho kom txias sai sai. Cold hardening yog tsom rau kev txhim kho hardness thiab hnav tsis kam ntawm cov yob.
6. Kev ua tiav: Chilled cam khwb cia hlau yob yog machined los ntawm kev txiav, sib tsoo thiab polishing txheej txheem los xyuas kom meej qhov zoo thiab geometric raug.
7. Kev sib dhos thiab kev sim: Cov yob tau sib sau ua ke nrog cov khoom siv zeb thiab cov kev xeem cuam tshuam tau ua los xyuas kom meej tias lawv cov kev ua tau zoo raws li qhov yuav tsum tau ua.
Raws li cov cuab yeej ncaj qha rau hlau deformation hauv cov txheej txheem dov, qhov zoo thiab kev pabcuam lub neej ntawm cov yob yog qhov tseem ceeb. Nyob rau tib lub sijhawm, cov yob kuj yog qhov tseem ceeb ntawm kev siv cov khoom lag luam metallurgical, cov nqi dov ntau lawm suav nrog qhov hnyav heev.
Chilled cam khwb cia hlau yob yog siv hlau nws tus kheej, qhov degree ntawm subcooling thiab casting qhov chaw ntawm cov nyhuv txias ntawm cam khwb cia hlau yob, nws cov ntsiab lus carbon feem ntau yog 2.9% ~ 3.2%, silicon cov ntsiab lus ntawm 0.25 % ~ 0.8%, chilled cam khwb cia hlau yob cov khoom belongs rau eutectic cam khwb cia hlau, raws li cov ntsiab lus alloy thiab hom sib txawv ntawm qhov sib txawv Muaj qee qhov sib txawv ntawm qhov sib txawv ntawm cov hlau cam khwb cia hlau yob thiab alloy chilled cam khwb cia hlau. yob raws li cov khoom siv thiab kev ua haujlwm.
1. cov khoom siv: cov khoom siv chilled cam khwb cia hlau yob feem ntau yog ua los ntawm cov hlau cam khwb cia zoo tib yam, thaum alloy chilled cam khwb cia hlau yob yog ua los ntawm cov hlau cam khwb cia zoo tib yam nrog qee cov ntsiab lus alloying, xws li chromium, molybdenum, titanium, thiab lwm yam.
2. Hardness: Alloy chilled cam khwb cia hlau rolls muaj hardness ntau dua piv rau zoo tib yam chilled cam khwb cia hlau yob, uas yog vim qhov sib ntxiv ntawm alloying ntsiab kom lub hardness ntawm yob nce, yog li txhim kho cov hnav tsis kam thiab siab tsis kam ntawm yob.
3. Hnav tsis kam: Vim tias cov alloy chilled cam khwb cia hlau yob muaj zog dua, nws hnav tsis kam kuj zoo dua. Nyob rau hauv qhov kub thiab txias ua hauj lwm ib puag ncig, lub alloy chilled cam khwb cia hlau rolls muaj ib tug ntev kev pab cuam lub neej piv nrog zoo tib yam chilled cam khwb cia hlau yob.
4. Thermal qaug zog tsis kam: Vim hais tias cov ntsiab lus ntawm cov alloy chilled cam khwb cia hlau yob tuaj yeem tiv thaiv kev loj hlob ntawm cov nplej thiab cov nplej tsiv teb tsaws,
rolls muaj zoo thermal qaug zog tsis kam, thiab tuaj yeem tiv taus deformation thiab rupture ntawm qhov kub thiab txias.
Cov hauv qab no tuaj yeem txiav txim siab thaum xaiv qhov zoo tib yam chilled cam khwb cia hlau yob lossis alloy chilled cam khwb cia hlau yob raws li qhov sib txawv:
1. Roll ua hauj lwm tej yam kev mob: Yog hais tias lub yob yuav siv nyob rau hauv high-temperature thiab high-pressure ua hauj lwm ib puag ncig, xws li kub dov, txias dov steel, thiab lwm yam., ces alloy chilled cam khwb cia hlau yob yog ib tug tsim nyog xaiv vim hais tias nws muaj ntau dua. hardness thiab tsis kam rau thermal qaug zog ua haujlwm.
2. Roll hardness yuav tsum: Raws li cov khoom yuav tsum tau dov, cov txheej txheem thiab cov khoom siv hardness, koj tuaj yeem xaiv alloy chilled cam khwb cia hlau rolls lossis zoo tib yam chilled cam khwb cia hlau yob. Alloy chilled cam khwb cia hlau rolls muaj zog dua, haum rau cov txheej txheem dov nrog siab hardness yuav tsum tau, thaum zoo tib yam chilled cam khwb cia hlau yob tuaj yeem ua tau raws li cov kev cai dav dav.
3. Kev xav txog kev lag luam: alloy chilled cam khwb cia hlau rolls piv rau tib yam chilled cam khwb cia hlau yob rau cov nqi nce, vim tias qhov sib ntxiv ntawm cov ntsiab lus alloying yuav ua rau tus nqi ntawm cov ntaub ntawv. Yog li ntawd, nyob rau hauv cov ntaub ntawv ntawm economic feasibility, raws li qhov yuav tsum tau ntau lawm ntim thiab cov khoom yuav tsum tau xaiv hom tsim nyog yob.
4. Kev pabcuam lub neej yuav tsum: Yog tias koj xav tau cov yob nrog lub neej ua haujlwm ntev dua thiab kev hnav zoo dua, tshwj xeeb tshaj yog nyob rau hauv kev siv siab, kev kub ceev thiab kev kub siab ua haujlwm ib puag ncig, alloy chilled cam khwb cia hlau yob yuav yog qhov kev xaiv zoo dua.
Nyob rau hauv cov ntsiab lus, nyob rau hauv kev xaiv ntawm zoo tib yam chilled cam khwb cia hlau yob los yog alloy chilled cam khwb cia hlau rolls, koj yuav tsum xav txog lub yob ua hauj lwm tej yam kev mob, hardness yuav tsum tau, kev khwv nyiaj txiag thiab kev pab lub neej yuav tsum tau thiab lwm yam, thiab raws li qhov tshwj xeeb tshwm sim ntawm kev xaiv.
