Farantin Alumina mai jure wa lalacewa: Babban abu don inganta aikin yawo a masana'antu

Farantin yumbu mai jure lalacewa na aluminawani abu ne mai aiki wanda aka yi ta hanyar haɗa yumbu mai ƙarfi na alumina (abun da ke cikin Al₂O₃ ≥92%) da matrix na roba ta hanyar tsarin vulcanization mai zafi. Yana haɗa ƙarfin yumbu mai ƙarfi da ƙarfin buffering na roba, wanda hakan ya sa ya dace da kariyar saman kayan aikin masana'antu a ƙarƙashin yanayi mai ƙarfi da lalacewa. Taurin Layer na yumbu na alumina na yau da kullun yana kaiwa HRA 85-90, yawansa yana tsakanin 3.6 zuwa 3.9 g/cm³, kuma juriyarsa ta sawa ta ninka ta faranti na ƙarfe na yau da kullun sau 10 zuwa 15.

Manyan ƙayyadaddun bayanai na aiki sun haɗa da: kauri tayal ɗin yumbu yawanci 15-30 mm, kauri na layin roba 4-15 mm, da kuma ƙarfin barewa gaba ɗaya ≥12 kN/m. Zafin aiki yana tsakanin -40°C zuwa +120°C, tare da juriya na ɗan lokaci har zuwa 150°C. Matsakaicin gogayya yana ƙasa da 0.2, wanda ke rage haɗarin mannewa da toshewar abu yayin jigilar kaya. Ta hanyar tsarin vulcanization, haɗin sinadarai a mahaɗin yumbu da roba yana hana rabuwa ko wargajewa, yana tsawaita rayuwar sabis da shekaru 3-5 idan aka kwatanta da layin ƙarfe na manganese na gargajiya.

Manyan aikace-aikacen sun haɗa da: wuraren canja wurin bel ɗin jigilar kaya, magudanar ruwa, da hoppers a masana'antar haƙar ma'adinai da haɗaka; magudanar ruwa da gidajen rabawa a masana'antar ƙarfe da siminti; da bututun digo na kwal a cikin tsarin sarrafa kwal na tashar wutar lantarki. A lokacin shigarwa, ana sanya farantin da aka yi wa vulcanized akan farantin tushe na kayan aiki ta hanyar haɗa sanyi ko vulcanization mai zafi, ba tare da maƙallan injina masu rikitarwa ba. Don yankunan da ke da matuƙar lalacewa, ana iya zaɓar tsarin haɗakar zirconia mai tauri (Al₂O₃-ZrO₂), wanda ke ƙara tauri na karyewa zuwa 4.5-5.5 MPa·m¹/², yana ƙara juriya ga lalacewar tasiri daga manyan kayan aiki.
