Ndedzipi mhando dze induction furnace lining materials?

Induction furnace lining material inonziwo induction furnace refractory material, induction furnace yakaoma vibrating material, induction furnace knotting material, induction furnace ramming material, yakakamurwa kuita acidic, neutral, uye alkaline lining materials. Iyo acidic lining material inogadzirwa ne-high-purity quartz, yakanyungudutswa Quartz ndiyo huru mbishi, composite additives inoshandiswa se sintering agent; iyo isina kwayakarerekera choto lining material inogadzirwa nealumina uye yakakwira aluminium zvinhu seyakanyanya mbishi zvinhu, uye iyo inosanganiswa yekuwedzera inoshandiswa seyo sintering agent; iyo yakakosha yevira yekubikira zvinhu inogadzirwa ne-high-purity fused corundum uye yakakwirira-kuchena magetsi Fused magnesia uye yakakwirira-kuchena spinel inoshandiswa sechinhu chikuru mbishi, uye composite additives inoshandiswa se sintering agents.

Kune matatu marudzi e induction furnace lining materials. Imwe iine acidic lining, iyo inoumbwa neyakaoma ramming yejecha requartz, uye musungo wekubatanidza ndiyo borax kana boric acid; imwe yacho yakaoma ramming uye kuumbwa kwe magnesia, uye chisungo chekubatanidza iborax kana boric acid. Imwe isimbi isina kwayakarerekera yevira, iyo yakanyungudutswa uye inoumbwa kubva yakakwira alumina bauxite clinker. Mumakore achangopfuura, nekuvandudzwa kwetekinoroji uye nekubuda kwezvinhu zvitsva zvakasiyana-siyana, zvinhu zvakawanda zvitsva zvembatya zvakaonekwawo mune induction furnace lining materials.

1. Acid lining

Acid furnace lining inonyanya kuita jecha requartz, iro rakachipa, rakagovaniswa zvakanyanya, kuvharisa kwakanaka, kuderera kwekuvaka zvinodiwa, hurema hushoma panguva yekushandiswa, uye kugadzirwa kwakagadzikana. Nekudaro, jecha re quartz rine yakaderera refractoriness uye haigone kusangana nezvinodiwa zvemahombe induction furnaces. Uye kune chikamu chechipiri shanduko panguva yekupisa, iyo yakagadzika kugadzikana kwakashata, kugadzikana kwekemikari hakuna kunaka, uye inongosangana ne slag kuita ngura. Kuti udzivise kukanganisa uku, fused quartz inogona kushandiswa. Zvirimo zvakakwirira, zviri musilicon dioxide zvakakura kupfuura 99%, refractoriness inofambira mberi zvakanyanya, padyo nenzvimbo yakanyunguduka, uye hapana chechipiri shanduko yechikamu pakupisa, hapana shanduko yekudziya, uye kuvhunduka kwekushisa kwakagadzikana. . Bonde rakwirawo zvakanyanya.

2. Neutral lining

Iyo yakasanganiswa corundum inoshandiswa sechigadziko chechoto chekupinza. Nemhaka yokuti nzvimbo yakanyunguduka ye white corundum yakakwirira se 2050 ℃, kuoma kwakakura kusvika ku 8. Inopfeka-inopesana, yakakwirira-yekushisa inodzivirira, uye ine kugadzikana kwemakemikari zviri nani kupfuura quartz. Inokodzera tembiricha yakakandwa yesimbi kana hombe yevira mbichana. Chimiro ndechekuti ine zvakare kukanganisa kwechikamu chekuchinja uye yakakura yekupisa yekuwedzera coefficient. Mukuita, kubatanidzwa kwespinel powder kunogona kufambira mberi zvakanyanya kupikisa kwekuora uye kugadzikana kwemaitiro.

3. Alkaline lining

Iyo yechinyakare alkaline choto lining inoumbwa nekuoma ramming ye magnesia. Iyo mukana ndeye yakakwirira refractoriness, padhuze ne2800 ℃, chikanganiso ndechekuti iyo yekuwedzera coefficient yakakura, iri nyore kutsemuka, iyo magnesia lining inodzivirira corrosion, hupenyu hurefu, mutengo wakaderera, uye inoshandiswa zvakanyanya. Kutora chikamu muchena corundum poda kana spinel poda inosimudzira zvakanyanya hupenyu hwebasa.

4. Spinel lining

Spinel lining rudzi rutsva rwekushongedza zvinhu. Iyo inoumbwa kubva kualuminium uye magnesia, inopiswa pakupisa kwepamusoro kana kugadziridzwa kuita spinel nemagetsi fusion, uye yobva yagadzira akasiyana particle zviyero sezvinodiwa. Inoshandiswa senge induction furnace lining, uye iyo yekubatanidza mumiriri ichiri Kusarudza borax kana boric acid ine zvakanakira chena corundum choto lining uye magnesia furnace lining, ichidzivirira kukanganisa kwayo. Ndiyo danho rekusimudzira rehombe-yakakura induction choto lining uye yakakwirira-tembiricha yevira. Zvinhu zvakawanda zvinotengeswa kunze kwenyika zvevira ndezverudzi urwu.

5. Tekinoroji nyowani uye zvinhu zvitsva zvemachira echoto

① Tora chikamu mune yekupedzisira-yakatsetseka poda (kunyanya mune mashoma mamicrons) mune yechinyakare simbi yekubikira zvinhu, izvo zvinogona kuvandudza kushivirira kwekuora uye nekupisa kugadzikana kwemidziyo yekubikira yevira, senge silica micro poda, alumina poda, chena corundum micro poda, spinel micro powder, nezvimwewo.

②Dry molding. Traditional choto linings zvose zvinoumbwa nehupfu yakaoma uye yakaoma ramming. Chikanganiso ndechekuti zviri nyore kuita chromatograph uye kuita hurema hwakadai sehusina chinhu. Mune semi-yakaoma nzira, 2% kusvika 3% kusanganiswa kwemvura kunoshandiswa kuderedza chromatography, uye kutendeseka kwakanaka, uye hakuzokonzeri kukuvadza kwakanyanya. Inongoda nguva shoma muchoto chepasi-tembiricha.

③Iyo semi-yakaoma molding process inotora chikamu mune yakachena calcium aluminate simende, ine yakachena acidic kana isina kwayakarerekera muchoto lining; ichiri mu alkaline choto lining, inotora chikamu mu magnesium oxide, sodium hexametaphosphate, nezvimwe.
