Pwm tooj liab-plated hnav-resistant phaj ua txoj kev
Crystallizer yog lub hauv paus tseem ceeb ntawm kev nruam casting steel hauv steelmaking. Cov tooj liab-coated hnav-resistant phaj ntawm crystallizer yog ib qho tseem ceeb thermal conductivity tivthaiv rau nruam nruam los ntawm cov kua molten steel rau solidified khoom billet plhaub, thiab nws zoo ncaj qha cuam tshuam rau qhov zoo ntawm lub billet thiab cov duab ceev ntawm lub nruam casting tshuab. Txhawm rau tiv thaiv cov phaj hnav-tiv taus zoo dua, zam kev sib cuag ntawm lub phaj hnav-resistant thiab molten steel, thiab txuas ntxiv lub neej ntawm pwm, txheej txheej ntawm cov phaj hnav-resistant yuav tsum muaj kev hnav zoo heev. Cov txheej txheem tam sim no yog:
1, hlau plating
Raws li kev sib xyaw ua ke ntawm cov khoom siv hlau tso, cov txheej txheem hlau tuaj yeem muab faib ua ib txheej txheej hlau, hlau hlau txheej thiab cov txheej txheem sib xyaw. Los ntawm kev ntxiv cov hlau nrog cov khoom sib txawv, cov txheej txheem alloy yog tsim los ntawm ib qho hlau txheej. Ib txheej txheej nrog cov khoom zoo heev tuaj yeem tau txais los ntawm kev ntxiv cov khoom thib ob rau hauv cov hlau lossis hlau. Muaj Ni txheej, Ni-Cr txheej, Co-Ni txheej, Ni-Fe-W txheej thiab lwm yam.
2, txheej txheej
Cov tshuaj tsuag txheej tuaj yeem tau txais ntawm qhov chaw ua haujlwm los ntawm kev siv thev naus laus zis thev naus laus zis. Cov txheej txheem tshwj xeeb yog kom sov cov khoom siv tshuaj tsuag mus rau lub xeev molten los yog semi-molten, atomize thiab ceev nws nrog high-speed airflow, thiab tshuaj tsuag rau saum npoo ntawm lub workpiece ntawm kev kub ceev. Cov khoom siv txheej muaj xws li hmoov, filamentary hlau, cermet thiab lwm yam khib nyiab, uas tuaj yeem tsim cov hlau alloy txheej, ceramic txheej thiab cermet txheej tom qab ua tiav. Muaj: Cr3C2p / NiCr txheej, ZrO2 / NiCr cermet txheej, thiab lwm yam.
3, laser cladding txheej
Laser cladding txheej yog siv high-zog laser beam irradiation, cov khoom sai melted, nthuav thiab solidified, tom qab complex lub cev, tshuaj thiab metallurgical hloov, nyob rau saum npoo ntawm substrate los tsim ib txheej tshwj xeeb tshuaj thiab txhua yam khoom ntawm composite. cov ntaub ntawv. Lub laser cladding txheej siv rau qhov chaw hloov kho ntawm crystallizer yog muab faib ua cov ntshiab hlau cladding txheej thiab cov txheej txheem sib xyaw nrog cov txheej txheem ntxiv.
4. Infiltration txheej
Cov txheej txheej infiltration yog txheej txheej hlau tsim los ntawm kev tso cov hlau los yog cov hlau ua haujlwm rau hauv qhov nruab nrab ntawm qhov kub thiab txias, kom ib lossis ob peb lub ntsiab lus nkag mus rau hauv qhov chaw ntawm lub workpiece. Lub infiltration txheej yog nrees ua ke nrog cov matrix, thiab hardness ntawm infiltration txheej yog siab dua. Tuav siab hardness thiab hnav tsis kam nyob rau tib lub sijhawm. Txawm li cas los xij, qhov sib txawv ntawm cov hlau thiab tooj liab lattice ntawm txheej infiltration yog qhov nyuaj rau kev tswj, thiab tus nqi siab txwv nws daim ntawv thov.
Tam sim no, nws zoo nkaus li tias tom qab xyoo ntawm txoj kev loj hlob, cov txheej hnav-tiv taus rau ntawm qhov chaw ntawm crystallizer raws li cov khoom siv electroplating tseem yuav nyob hauv txoj haujlwm tseem ceeb. Thermal spraying thiab laser cladding coatings kuj yuav tsim nyob rau hauv lub sij hawm ntev vim lawv tus kheej kev ua tau zoo. Nyob rau hauv lub neej yav tom ntej, txheej hnav-resistant txheej npaj los ntawm electroplating technology yuav coexist nrog rau lwm nto technology hnav-resistant txheej thiab ntxiv ib leeg.
