Kusashanda zvisina kurongeka kwechoto chekunyunguduka kunokonzeresa tsaona dzakakomba

The kudonhedzwa kunyorera vira pachayo kubatana kwezvitatu masisitimu emagetsi, mvura, uye oiri. Kuvhiya zvisina kurongwa kunowanzokonzera tsaona dzakakomba. Izvi zvinotevera zvinorambidzwa zvachose:

(1) Chaji isina kukodzera uye flux inowedzerwa muchoto;

(2) Batanidza simbi yakanyungudutswa ine yakaremara kana yakanyorova ladle lining;

(3) Chigadziko chechoto chinowanikwa chakakuvadzwa zvakanyanya, uye kunyungudutswa kunopfuurira;

(4) Kuvhundutsa kwechisimba kumagetsi echoto;

(5) Choto chinomhanya chisina mvura inotonhorera;

(6) Simbi yakanyungudutswa kana choto chimiro chemuviri chinoshanda pasina pasi;

(7) Mhanya pasi peyakajairwa magetsi kuchengetedza interlock dziviriro;

(8) Kana choto chisina kusimba, ita kuchaja, ramming charge yakasimba, sampling, uye kuwedzera.

Batch alloy, kuyerwa kwekushisa, kubviswa kwe slag, nezvimwewo Kana mamwe emabasa ataurwa pamusoro apa achifanira kuitwa nemagetsi, matanho akakodzera ekuchengetedza anofanirwa kutorwa, sekupfeka shangu dzekudzivirira uye kupfeka magirovhosi easbestos.

Basa rekugadzirisa chevira uye rinotsigira zvigadzirwa zvemagetsi zvinofanira kuitwa munyaya yekukundikana kwesimba.

Kana choto chiri kushanda, zvinodikanwa kunyatso tarisisa tembiricha yesimbi, chiratidzo chetsaona, tembiricha inotonhorera yemvura uye chiyero chekuyerera panguva yekunyungudika. Iyo yevira simba chinhu chinogadziriswa kusvika pamusoro pe 0.9, uye iyo-nhatu-chikamu kana matanhatu-chikamu chezvino chakanyanya kuenzana. Iyo yekubuda kwemvura tembiricha ye sensor, nezvimwewo haipfuure iyo yakanyanya kukosha inotsanangurwa mudhizaini. Muganho wakadzika wekudziya kwemvura inotonhorera unowanzo kutariswa pamamiriro ekuti hapana condensation inoitika pamadziro ekunze kwe sensor, kureva, tembiricha yemvura inotonhorera yakakwira zvishoma pane ambient tembiricha yemhepo. Kana aya mamiriro asina kusangana, condensation ichaitika pamusoro peiyo sensor, uye mukana wekuputsika kwe sensor uchawedzera zvakanyanya.

Mushure mekugadzirwa kwemakemikari uye tembiricha yesimbi yakanyungudutswa inosangana nezvinodiwa, simba rinofanira kugurwa uye simbi inofanira kubatwa nenguva.

Pakupera kwekunyungudika, simbi yakanyungudutswa inopera. Kuti udzivise kukurumidza kutonhora kubva pakugadzira kuputika kukuru mumucheka wechoto, matanho akakodzera ekutonhodza anononoka anofanirwa kutorwa, sekuwedzera mahwendefa easbestos kune chivharo checrucible; gomba repombi rakavharwa nezvidhinha zvekudzivirira uye jecha remuenzaniso; Mukaha uripo pakati pechifukidziro chechoto uye muromo wechoto wakavharwa nevhu refractory kana jecha remuenzaniso.

Kune crucible induction yekunyungudutsa mavira ane hukuru hukuru, mushure mekushanda kwekunyungudutsa, edza kudzivirira kutonhora kuzere kwebira rechoto. Nzira dzinotevera dzinogona kushandiswa:

(1) Chengeta chikamu chesimbi yakanyungudutswa muchoto uye simbisa pamhepo yakaderera kuchengetedza tembiricha yesimbi yakanyungudutswa inosvika 1300 ℃;

(2) Isai heater yemagetsi kana kushandisa gasi rinopisa mu crucible kuchengetedza tembiricha ye crucible lining pa 900～1100℃;

(3) Mushure mekumisa choto, simbisa chivharo chechoto, uye nenzira yakakodzera kuderedza kutonhora kwemvura kuyerera kweinductor, kuitira kuti bhiza rechoto rinopisa ritonhodzwe zvishoma nezvishoma kusvika pa1000 ℃, uyezve yakadirwa simbi yesimbi ine chimiro chakafanana. seyakarovera asi idiki muhukuru Sundira muchoto, uye simbisa pakupisa kuchengetedza tembiricha iri pa1000 ℃. Kana vira rinotevera richitanga kunyungudutsa, ingot inoshandiswa sefrit.

Kana choto ichida kuvharwa kwenguva yakareba, hapana chikonzero chekuchengeta crucible ichidziya. Kuti uchengetedze zvirinani chigadziko chechoto pasi pemamiriro emvura inotonhorera, mushure mekunge simbi yakanyungudutswa mucrucible yapera, frit inosimudzwa mukati uye tembiricha inokwira kusvika 800 ~ 1000 ℃, ipapo chivharo chechoto chakavharwa, simba. inogurwa, uye choto Inodziya uye inotonhorera zvishoma nezvishoma. Kutsemuka kuchaonekwa pachena mumucheka we crucible mushure mekunge choto chavharwa kwenguva yakareba. Kana yanyungudutswa zvakare yoshandiswa, inofanira kunyatsoongororwa uye kugadziriswa. Kana ichinyunguduka, tembiricha inofanira kusimudzwa zvishoma nezvishoma kuitira kuti madiki madiki akaumbwa mumucheka wechoto avharwe ega.

Munguva yekushanda kwechoto, mamiriro emucheka wevira anofanira kuongororwa nguva dzose kuti ave nechokwadi chekugadzirwa kwakachengeteka uye kuvandudza hupenyu hwehuni hwechoto. Nzira dzisina kururama dzekushanda dzinowanzokonzera kupfupisa hupenyu hwebindu rechoto, saka zvinotevera zvinowanzoitika zvikanganiso zvinofanirwa kudzivirirwa:

(1) Chigadziko chevira hachina kuputirwa, kubikwa uye kupiswa maererano nemaitiro akatemwa;

(2) Iko kuumbwa uye fomu yekristaro yezvigadzirwa zvemucheka hazvienderane nezvinodiwa, uye zvine zvimwe zvitsvina

(3) Kupisa kwekushisa kwesimbi yakanyunguduka muchikamu chekupedzisira chekunyunguduka kunodarika muganhu unobvumirwa;

(4) Kushanda kusina kururama uye kutyisa kwemagetsi kwakashandiswa pakutakura zvinhu zvakasimba kana bhiriji nekuda kwekubuda kwezvinhu zvevira, zvichikonzera kukanganisa kwakakomba kune crucible lining;

(5) Mushure mokunge choto chavharwa, chigadziko chevira chinodzimwa uye kuputika kukuru kunoitika.

Kana choto chikavhiringidzwa, huwandu hwemvura inotonhorera ye sensor inogona kuderedzwa zvakakodzera, asi haibvumirwi kudzima mvura inotonhora, kana zvisina kudaro kupisa kwakasara kwechigadziko chechoto kunogona kupisa chigadziko chekudzivirira che sensor. Chete apo kutonhora kwepamusoro kwechigadziko chevira kunodonha pasi pe100 ° C, mvura inotonhorera yeinductor inogona kuvharwa.
