Method for detecting the lining of induction melting furnace

1. Kukukurwa pasi pechoto

Mukushandiswa kwakajairwa kwebindu rechoto, ukobvu hwebindu rechoto uye ukobvu hwepasi pechoto huchave hutete zvishoma nezvishoma nekuda kwekukukurwa kweiyo cyclic yesimbi yakanyungudutswa panguva yekushandiswa kwenguva refu. Iyo intuitive mamiriro ezvinhu ndeyekuwedzera kwehuni hwehuni, uye iyo yakawanda yevira yemoto ichave yakasvibiswa ne 30-50%. Kana nguva yasvika, ichaputswazve, uye basa idzva rokuvaka choto richaitwa.

Kubva pakuongororwa kwechigadziko chechoto chese, kukukurwa kuri pachena kuri panzvimbo yemateru apo pasi pechoto uye chigadziko chevira zvinosanganiswa. Mushure mekushandiswa kwenguva refu kwechoto, iyo yakakora yehuni yakabatisa zvinhu pamateru yakanyungudutswa kuti ive yakafanana neyakagadzika choto. Chigadziko chechoto chiri pane denderedzwa arc pamusoro, uye kunyange kuderera kuduku kunoonekwa muvhu umo muchoto wepasi zvinhu uye simbi yemoto inosanganiswa. Sezvo zera revira rinowedzera, kuora mwoyo panzvimbo iyi kunowedzera kudzika uye kwakadzika, kuswedera pedyo uye pedyo nechoto chemoto chemagetsi , Uye kukanganisa kushandiswa kwekuchengeteka, unoda kuvakazve choto. Mukuwedzera kune kuwanda kwejecha re quartz panguva yekuvakwa kwechoto, chikonzero chekuora mwoyo kwevheni kunobatanidzawo nemakemikari ekuora panguva yekunyunguduka kwezvinhu zviri mukushandiswa kwedu uye kugadzirwa kwemagetsi panguva yekushanda.

2. Kutendeseka kwechigadziko chevira

Kutendeseka kwemucheka kunoreva kupinda kwesimbi uye kutsemuka kunowanzoonekwa mumucheka. Mukugadzirwa kwedu, kazhinji kune kupera kwevhiki uye mavira. Kana choto chemagetsi chikadururwa uye chikamira kunyunguduka, chigadziko chechoto chinotonhora zvishoma nezvishoma. Nekuda kwekuti sintered choto lining chinhu chine brittle, iyo sintered layer haidzivisike nekuda kwekuwedzera kwekupisa uye kuderera. Mitswe inooneka, iyo inokuvadza zvikuru uye ichaita kuti simbi yakanyungudutswa ipinde mukati mebindu rechoto uye inokonzera kubuda kwechoto.

Kubva pakuona kwekudzivirira jira, kuputika kwacho kwakanyanyisa uye kwakanyanyisa uye kwakagoverwa zvakaenzana, nokuti chete nenzira iyi kuputika kunogona kuvharwa kusvika kumagumo apo choto chinotonhora, uye chigadziko chakakwana che sintering chinogona kupiwa kune lining. Kuti tideredze kupararira kwekutsemuka, isu tinofanirwa kutarisisa kune: kudzivirira lining sticking slag, pesvedzero yekunyanyisa tembiricha pabira rechoto, kutonhora kwebindu rechoto, uye kugara uchiongorora pamusoro pechoto.
