Raws li qhov sib txawv binders rau lub plhaub tsev, lub peev casting yuav muab faib ua silica sol binder peev casting, dej iav binder peev casting thiab peev casting nrog lawv cov khoom sib tov ua cov ntaub ntawv binder. Silica sol yog ib yam dej-raws li khi nrog ib tug silicic acid colloid qauv. Nws yog ib tug polymer colloidal tov nyob rau hauv uas heev dispersed silica hais yog soluble nyob rau hauv dej. Cov colloidal hais yog spherical thiab muaj ib txoj kab uas hla ntawm 6-100 nm. Cov txheej txheem ntawm peev casting los ua lub plhaub yog txheej txheem ntawm gelling. Muaj ntau yam cuam tshuam rau gelation, feem ntau yog electrolyte, pH, sol concentration thiab kub. Muaj ntau hom kev lag luam silica sols, thiab feem ntau siv yog alkaline silica sol nrog cov ntsiab lus silica ntawm 30%. Txhawm rau kov yeej qhov tsis txaus ntawm lub plhaub ntev ua lub voj voog ntawm silica sol plhaub, ib qho kev ziab silica sol tau tsim nyob rau xyoo tas los no. Cov txheej txheem ntawm kev ua silica sol plhaub yog qhov yooj yim. Txhua txheej txheem muaj peb txheej txheem: txheej, xuab zeb, thiab ziab. Txhua tus txheej txheem yog rov ua ntau zaus kom tau txais lub plhaub multilayer ntawm qhov yuav tsum tau ua kom tuab.
Hauv silica sol plhaub ua txheej txheem, ziab yog txheej txheem tseem ceeb tshaj plaws. Los ntawm kev ziab, cov dej yog volatilized, silica sol gels, thiab cov khoom refractory yog ruaj khov ua ke, yog li tau txais lub plhaub muaj zog. Qhov no yog ib qho kev npaj zoo rau lub tom ntej casting. Lub casting tau txais los ntawm silica sol plhaub ua cov txheej txheem muaj qis nto roughness, siab qhov tseeb thiab ntev lub plhaub ua voj voog. Cov txheej txheem no yog siv dav hauv casting high-temperature heat-resistant alloys, heat-resistant steels, stainless steels, carbon steels, low alloys, aluminium alloys and copper alloys.
Lub silica sol precision poob ciab peev casting txheej txheem yog tsim rau rov ua dua tshiab ntawm cov khoom sib txuas los ntawm ntau yam hlau sib txawv thiab kev ua haujlwm siab alloys. Txawm hais tias feem ntau yog siv rau cov me me castings, cov txheej txheem no tau siv los ua tiav qhov rooj dav hlau qhov rooj, nrog cov hlau castings txog li 500 kgs thiab aluminium castings txog li 50 kgs. Piv rau lwm cov txheej txheem casting xws li tuag casting lossis xuab zeb casting, nws tuaj yeem yog cov txheej txheem kim. Txawm li cas los xij, cov khoom uas tuaj yeem tsim tau siv peev casting tuaj yeem suav nrog cov duab sib txawv, thiab feem ntau cov khoom raug cam khwb cia nyob ze cov duab, yog li yuav tsum tau me me los yog tsis muaj rework ib zaug cam khwb cia.
Raws li qib ntawm cov ntsiab lus carbon, carbon steel rau casting feem ntau muab faib ua cov pa roj carbon tsawg, nruab nrab carbon steel thiab siab carbon steel. Cov cam khwb cia carbon steels ntawm tag nrho cov teb chaws nyob rau hauv lub ntiaj teb no yog feem ntau muab faib raws li lawv lub zog, thiab coj cov qib yog formulated.
Hais txog cov tshuaj muaj pes tsawg leeg ntawm carbon steel, tshwj tsis yog rau phosphorus thiab sulfur, tsis muaj kev txwv lossis tsuas yog txwv sab saud ntawm lwm cov tshuaj. Nyob rau hauv cov ntaub ntawv saum toj no, cov tshuaj muaj pes tsawg leeg ntawm cam khwb cia carbon steel yog txiav txim los ntawm lub foundry raws li qhov yuav tsum tau txhua yam khoom.
Txoj kev kho cua sov ntawm carbon steel castings feem ntau yog annealing, normalizing lossis normalizing + tempering. Rau qee qhov siab carbon steel castings, quenching thiab tempering tuaj yeem siv tau, uas yog, quenching + kub tempering, thiaj li los txhim kho cov khoom siv kho txhua yam ntawm carbon steel castings. Me carbon steel castings tuaj yeem ncaj qha quenched thiab tempered los ntawm lub xeev li-cam khwb cia. Rau loj-scale los yog complex-shaped carbon steel castings, nws yog tsim nyog los ua quenching thiab tempering kev kho mob tom qab normalizing kev kho mob.
Hauv kev lag luam casting thiab metallurgical, ferrous hlau txhais tau tias cov hlau thiab lawv cov alloys uas muaj hlau. Cov hlau ferrous muaj xws li steel thiab npua hlau thiab cov foundries feem ntau muab faib ua ob pawg loj: cam khwb cia hlau (grey cam khwb cia hlau, ductile cam khwb cia hlau, malleable cam khwb cia hlau, vermicular graphite cam khwb cia hlau thiab lwm yam) thiab cam khwb cia hlau (cam khwb cia carbon steel, cam khwb cia hlau). alloy steel, stainless hlau thiab lwm yam). Los ntawm cov txheej txheem ua npuas dej ploj, RMC Casting Foundry tuaj yeem nchuav hlau hlau, hlau hlau, hlau hlau thiab carbon hlau.
