Ceramic sand for foundry ine yakanaka kushandisa zvakare kuita: zvakaderera zvinodiwa zvejecha rekushandisa, kushandiswa kwesimba kwakaderera uye mutengo wakaderera wekurapa jecha.Iyo jecha rekudzoreredza mwero wakasvika 98%, gadzira shoma yekurasa tsvina.Nekuda kwekushaikwa kwebhainda, jecha rakarasika rinozadza furo rine mwero wepamusoro wekudzoreredza uye mutengo wakaderera, unosvika 1.0-1.5kg/tani yejecha rekushandisa kwekukandira.

Mumakore achangopfuura, akarasika mabhizinesi ekukanda furo akakanganiswa nezvinhu zvakawanda, zvichikonzera yakaderera mwero wekupedza castings.Pakati pavo, mutengo wepamusoro wekugadzira wekukanda, chiyero chepamusoro uye yakaderera mhando yave matambudziko matatu mumabhizinesi akarasika ekukanda furo muChina.Maitiro ekugadzirisa matambudziko aya uye nekuvandudza mutengo wekuita kwekukanda zvigadzirwa panguva yekutanga rave rimwe remabasa epamusoro emakambani ekutanga.Sezvatinoziva tese, kusarudzwa kwejecha mukukandira chikamu chakakosha chemaitiro ese.Kana jecha risina kunyatsosarudzwa, richakanganisa mamiriro ose ezvinhu.Naizvozvo, mabhizinesi akarasika ekukanda furo anofanirwa kuita mamwe mabasa mukusarudzwa kwejecha.

Zvinoenderana nedata rakakodzera, makambani mazhinji ekutanga akavandudza sarudzo yavo yejecha, achiramba echinyakare yakaderera-mutengo wejecha requartz kana jecha reforsterite, uye kushandisa rudzi rutsva rwejecha redhakamic kuvandudza dambudziko rekukanda.Iri rudzi rutsva rwejecha rine zvakanakira refractoriness yakakwirira, yakanaka fluidity, yakakwirira gasi permeability uye yakafanana kuwanda density ine quartz jecha.Iyo inogadzirisa kukanganisa mukukanda kugadzirwa kune imwe nhanho, uye yave ichinetsekana zvakanyanya neiyo indasitiri yepasirese foundry.Matambudziko matatu makuru ekukanda mutengo, chiyero chakakanganisika uye mhando yemabhizinesi akarasika anokanda furo akaderedzwa zvine mutsindo, uye foundry ceramic jecha zvakare rakadiwa nemabhizinesi mazhinji.

Advantage

● High refractoriness (>1800°C), inogona kushandiswa kukanda zvinhu zvakasiyana-siyana.Iko hakuna zvakare kudikanwa kwekushandisa dzakasiyana mhando yejecha maererano nezvinhu.

● High reclamation rate.Iyo jecha rekudzoreredza mwero wakasvika 98%, gadzira shoma yekurasa tsvina.

● Kuyerera kwakanakisa uye kushanda zvakanaka kwekuzadza nekuda kwekutenderera.

● Lower Thermal kuwedzera uye Thermal Conductivity.Zviyero zvekukanda zvakanyanya uye yakaderera conductivity inopa zvirinani mold kuita.

● Kuderera kwehuwandu hwakawanda.Sezvo artificial ceramic jecha rinenge hafu yakareruka sejecha receramic rakasanganiswa (black ball jecha), zircon uye chromite, rinogona kubuda zvakapetwa kaviri nhamba yezviumbwa pahuremu hweyuniti.Inogona zvakare kubatwa zviri nyore, kuchengetedza vashandi uye kutamisa simba mari.

● Kugovera kwakagadzikana.Kwegore kugona 200,000 MT kuchengetedza kukurumidza uye kugadzikana kwekupa.
