Mibvunzo yechikwata chekutenga matombo pa48-52 HRC vs 55-60 HRC bucket teeth
Ndeipi HRC yakanakira mazino emabhaketi mumagori egranite?
48-52 HRC ndiyo nzira yakanakisisa yekuomarara kwemazino emabhaketi mumagori egranite. Zino rebhaketi reJoin Machinery rakarasikirwa newakisi K40RC rinosvika 48-52 HRC kuburikidza nekudziya mushure mekudzima, izvo zvinopa mwero wekuchekwa kwemazino we0.78 mm/meno mukati memaawa makumi mana nemaviri ekuyedzwa kwekukwekwa kwegranite, maawa 2,400 ekushanda, uye mwero wekuchekwa kwezino we0%. Musanganiswa we48-52 HRC + wakisi yakarasikirwa ndiyo yega nzira inopona kukwekwa kwegranite kwakanyanya (SiO2 > 70%) pamwe nekukwekwa kwakanyanya.
Ndeupi musiyano uripo pakati pe48-52 HRC ne55-60 HRC yemazino ebhaketi?
Musiyano uripo pakati pe48-52 HRC ne55-60 HRC yemazino ebhaketi unosanganisira zviyero zvina: (1) Kusimba kweCharpy paISO 148-1 — 48-52 HRC inopa 35-45 J vs 55-60 HRC inopa 12-18 J, kuderedza kuoma kwe70-75%; (2) mwero wekupfekwa kwegranite paISO 3685 — 48-52 HRC = 0.78 mm/mazino vs 55-60 HRC = 0.45 mm/mazino mumaawa makumi mana nemaviri; (3) mwero wekuchekwa kwezino — 48-52 HRC = 0-1% vs 55-60 HRC = 5-8%; (4) hupenyu hwekushanda — 48-52 HRC = maawa 2,400 vs 55-60 HRC = maawa 1,100, kuwedzera kwehupenyu hwe2.2x.
Ko HRC yakakwirira inogara iri nani here pamazino ebhaketi?
Kwete, HRC yakakwira haisi nguva dzose iri nani kune mazino ebhaketi. Kuchinjana kwekuomarara vs kusimba kunogumira pafizikisi: sezvo HRC ichiwedzera kupfuura 52 HRC, kusimba kweCharpy kunoderera kubva pa35-45 J kusvika 12-18 J (kudzikira kwe70-75%), izvo zvinokonzera kupwanyika uye kuputsika mumashandisirwo ane simba guru. HRC yakanakisa ndeye 48-52 HRC yemagwenga egranite ne limestone, 55-60 HRC yemagwenga ebasalt, 52-56 HRC yemagwenga esimbi.
Ndeipi nzira yekurapa kupisa kwemazino ebhaketi e48-52 HRC?
Maitiro ekurapa mazino emabhaketi e48-52 HRC ane matanho mashanu: (1) kuomesa mazino pa880-920°C kwemaminitsi 60-90; (2) kudzima mafuta kubva pa880-920°C kusvika 80-120°C mumafuta anodzima nekukurumidza; (3) kudziya pa200-250°C kwemaminitsi 120-180 kuti uwane 48-52 HRC + 35-45 J kuoma; (4) kurapwa kwe cryogenic pa -196°C kwemaawa makumi maviri nemana; (5) kuderedza kushushikana pa150-180°C kwemaminitsi makumi matanhatu.
Ndeipi nzira yekubatanidza adapter hardness pairing yemazino emabhaketi e48-52 HRC?
Nzira yekubatanidza adapter hardness inoda 40-45 HRC hardness, iyo iri 7-12 HRC yakaderera pane bucket tooth. 7-12 HRC differential inogadzira 7-10x replacement ratio: mushandi anotsiva bucket tooth yakachipa ka7-10 asati atsiva adapter inodhura. 7-10x ratio inodzivirira mari yeadapter uye inotarisa kupfeka pabucket tooth yakachipa inotsiviwa.
Musiyano wemutengo weFOB pachikamu chimwe nechimwe uripo pakati pe48-52 HRC ne55-60 HRC bucket teeth?
Musiyano wemutengo weFOB pachikamu chimwe nechimwe i$14-22 pachidimbu chimwe nechimwe: 48-52 HRC lost-wax = $36-48 pachidimbu chimwe nechimwe vs 55-60 HRC sand-cast = $22-26 pachidimbu chimwe nechimwe. 48-52 HRC lost-wax specification inopa mutengo wakaderera we10-15% paawa imwe neimwe ($0.018-0.020 vs $0.020-0.024) pasinei nemutengo wekutanga wakakwira ne60-90%, inova ndiyo hwaro hwe48-52 HRC specification inosarudzwa pakutenga granite quarry.
