Txawm hais tias tus nqi ntawm cov xuab zeb ceramic yog ntau dua li ntawm silica xuab zeb thiab quartz xuab zeb, yog tias nws siv tau zoo thiab suav tau zoo, nws tuaj yeem tsis tsuas yog txhim kho qhov zoo ntawm castings, tab sis kuj txo cov nqi tsim khoom.
1. Lub refractoriness ntawm ceramic xuab zeb yog siab dua li ntawm silica xuab zeb, thiab lub compactness ntawm filling thaum lub sij hawm molding yog siab, yog li qhov zoo ntawm castings tuaj yeem txhim kho thiab cov seem ntawm cov khoom yuav raug txo;
2. Spherical ceramic xuab zeb muaj fluidity zoo. Rau qhov nyuaj-puab castings, nws yog ib qho yooj yim los sau nruj qhov chaw uas nyuaj rau sau, xws li cov ces kaum sab hauv, tob recesses, thiab lub tiaj tus. Yog li ntawd, nws tuaj yeem txo cov xuab zeb-packing tsis xws luag hauv cov khoom no, thiab txo cov haujlwm ntawm kev tu thiab ua kom tiav;
3. Zoo crush kuj, siab rov qab tus nqi, thiab correspondingly txo pov tseg emissions;
4. Lub thermal expansion tus nqi yog me me, lub thermal stability yog zoo, thiab lub thib ob theem kev hloov yuav tsis ua rau expansion defects, uas zoo heev txhim kho qhov seem raug.
Qhov saum npoo ntawm cov xuab zeb ceramic yog du heev, thiab cov nplaum nplaum rau ntawm cov xuab zeb nplej tuaj yeem tev tawm nrog kev sib txhuam me ntsis ntawm cov xuab zeb qub. Ceramic xuab zeb hais muaj siab hardness thiab tsis yooj yim rau tawg, yog li lub peev xwm reclamation ntawm ceramic xuab zeb yog tshwj xeeb tshaj yog muaj zog. Ntxiv mus, ob qho tib si thermal reclamation thiab mechanical reclamation txoj kev yog haum rau ceramic xuab zeb. Hais lus zoo, tom qab lub foundry siv cov xuab zeb ceramic, nws tuaj yeem sau cov xuab zeb qub yam tsis muaj nqi ntau. Nws tsuas yog yuav tsum tau tshem tawm qhov sib koom ua ke ntawm cov xuab zeb nto, thiab tom qab ntawd nws tuaj yeem rov tsim dua thiab rov siv dua tom qab kuaj xyuas. Ua li no, cov xuab zeb ceramic tuaj yeem rov ua dua thiab rov siv dua. Nyob ntawm qhov zoo ntawm cov khoom siv reclamation, lub sij hawm ceramic xuab zeb reclamation feem ntau yog 50-100 zaug, thiab qee cov neeg siv khoom txawm tias ncav cuag 200 zaug, uas txo cov nqi siv ntau, uas tsis tuaj yeem hloov los ntawm lwm cov xuab zeb.
Lub casting tsim los ntawm ceramic xuab zeb uas tau reclaimed ntau tshaj 20 zaug.
Nws tuaj yeem hais tias kev siv cov xuab zeb ceramic, reclamation yog ib qho cuab yeej zoo, uas yog unmatched los ntawm lwm cov xuab zeb foundry.
