Dab tsi yog qhov txawv ntawm qhov khoob thiab dub ntawm malleable steel yeeb nkab fittings?
May 22, 2023
Kev tsim khoom ntawm malleable steel yeeb nkab fittings txais cov xuab zeb pwm casting txoj kev. Cov xuab zeb pwm yuav tsum tau ua nrog cov xuab zeb xuab zeb. High-quality molding xuab zeb yog qhov yuav tsum tau ua ua ntej thiab cov xwm txheej rau kev ua kom zoo castings.
Cov xuab zeb moulding siv rau malleable steel yeeb nkab fittings yog tsim los ntawm cov xuab zeb dawb, bentonite, thee hmoov thiab qee cov xuab zeb qub uas tau muab sib xyaw rau hauv ib qho kev faib ua feem.
Txij li cov xuab zeb molding yuav tsum tiv taus qhov kub ntawm cov hlau molten, nws yuav tsum muaj qee yam tsis kam rau sintering, thiab yuav tsum tsis muaj cov khoom siv hlau thiab humus hauv cov xuab zeb molding. Cov xuab zeb dawb siv hauv cov xuab zeb molding ntawm Kanefma steel yeeb nkab fittings yog ntxuav dawb xuab zeb los ntawm Inner Mongolia, nrog cov ntsiab lus SiO2 siab, siab sintering kub, thiab tsawg heev impurities tom qab ntxuav. Bentonite yuav tsum muaj cov khoom zoo adhesion thiab haum thermal stability, thiab Kanef xaiv Jianping Weike bentonite. Dab tsi pulverized thee xaiv rau siv yog xaiv pulverized thee.
Ntau cov qauv tseem ceeb los ntsuas qhov kev ua tau zoo ntawm cov xuab zeb moulding rau malleable steel yeeb nkab fittings muaj xws li ya raws, huab cua permeability, lub zog, compaction npaum li cas, deformation, crushing Performance index, fluidity, av nkos ntsiab lus, zoo av nplaum ntsiab lus, particle muaj pes tsawg leeg, Burmese tshuaj, xuab zeb kub, thiab gas tiam. cov khoom, zoo pulverized thee cov ntsiab lus, poob ntawm ignition, sand inclusion resistance, sand sticking resistance, etc.
Raws li lub hauv paus ntawm malleable steel yeeb nkab fittings, qhov muaj pes tsawg leeg thiab kub ntawm cov hlau molten muaj kev cuam tshuam zoo rau cov khoom siv ntawm cov yeeb nkab fittings. Yog li ntawd, nruj me ntsis tswj lub Cheebtsam ntawm ntau yam nyob rau hauv lub molten hlau, thiab tswj qhov kub ntawm cov hlau molten los ntawm lub cub tawg thiab casting yog lub hauv paus rau ua zoo malleable steel yeeb nkab fittings. Smelting yog ib qho tseem ceeb ntawm kev tsim cov hlau castings, thiab qhov zoo ntawm cov hlau castings nyob ntawm qhov zoo ntawm cov hlau molten. High-quality molten hlau yuav tsum ua raws li cov cai hauv qab no:
(1) Cov tshuaj muaj pes tsawg leeg ua tau raws li qhov yuav tsum tau ua thiab nyob ruaj khov;
(2) Qhov kub thiab txias txias yog qhov tsim nyog;
(3) Cov ntsiab lus ntawm cov pa oxygen, nitrogen, hydrogen thiab qee cov khoom siv microscopic yog nyob rau hauv kev tswj xyuas;
(4) Cov ntsiab lus tsawg ntawm qhov nyuaj-rau-sib cais thiab theem nrab suav nrog.
Cam khwb cia hlau smelting tsis yog tsuas yog ib txoj kev melting xwb. Cov txheej txheem no muaj qee qhov kev cuam tshuam metallurgical thiab cuam tshuam los ntawm ntau yam hauv ob qho tib si metallurgical thermodynamics thiab kinetics. Yog li ntawd, peb yuav tsum sim peb qhov zoo tshaj plaws los siv ntau yam txuj ci los tswj kev cuam tshuam ntawm ntau yam metallurgical yam thiab ua rau lawv lub zog los tsim cov hlau molten zoo.
