Induction furnace lining sintering uye nzira yekubheka

Induction furnace lining sintering uye kubika nzira

Kupisa uye kubheka kwechoto kunofanirwa kuve kwakavakirwa pakukwanisa uye chimiro chevira (crucible furnace kana grooved vira) uye yakasarudzwa refractory choto zvinhu kugadzira inoenderana chivakwa chechoto, kubika uye sintering maitiro.

Nechoto chekupinza, yekutanga kunyunguduka mushure mekunyunguduka kunofanirwa kunyungudutswa zvizere kuitira kuti chikamu chemuromo wechoto chinyatso kunyungudika. Kuti uderedze kukora kwebindu rechoto nemagetsi kubvongodza, magetsi ekushanda anofanirwa kudzikiswa panguva yekunyunguduka uye kunyungudika. Mhepo inofanira kuva 70-80% yevheji yakarongwa (panguva ino, simba iri 50-60% yesimba rakarongwa). Mushure mekunge sintering yapera, mavira akawanda anofanirwa kunyungudutswa nguva dzose, izvo zvinoita kuti uwane crucible yakakwana uye ine mhedzisiro yakanaka pakuvandudza hupenyu hwebiravira rechoto. Paunenge uchinyunguduka mumavira mashoma ekutanga, shandisa chaji yakachena uye isina ngura zvakanyanya sezvinobvira, zviri nani kunyungudutsa pasi-carbon cast iron. Munguva yekunyunguduka, zvinodikanwa kuti udzivise nzira iyo inowedzera kuonda kwembambo yevira, senge nzira yekuwedzera kabhoni.

Nokuda kwechoto chekupinza, nekuda kwechimiro chakaoma chemuviri wechoto, uye kusarudzwa kwekunyorova kana kuoma kwechoto kuvaka, huni inofanira kupiswa zvishoma nezvishoma kwenguva yakareba kuti iome uye sinter chigadziko chevira. Mushure mekunge mutumbi wekupinza wevira uchisimbiswa, kupisa kwe crucible tire mold kunokonzera kuti chigadziko chechoto chiomeswe, uye imwe yose yevira inoda kuvimba kune dzimwe nzvimbo dzekupisa pakutanga. Kana choto chaomeswa uye chasvika kune imwe sintering tembiricha, inonyungudutswa nemuviri wekupinza. Simbi kana simbi yakanyungudutswa inobayiwa kuti zvishoma nezvishoma isvike pakupisa tembiricha. Iyo induction choto inofanira kumhanya ichienderera kubva kune yekutanga kubheka uye sintering ye lining. Kuomeswa kwechoto uye sintering process inofanira kunyatsoita zvekupisa zvinotsanangurwa, uye panguva imwe chete, teerera kudzivirira kuitika kwezviitiko zvegoronga. Panguva yekushanda kwakajairika, gara uchiteerera kune shanduko yeyakanyungudutswa chiteshi chemugero.
