Zvigadzirwa zve graphite zvinoshandiswa zvakanyanya

Graphite chinhu chakasiyana-siyana chine huwandu hwakawanda hwekushandisa uye zvakanakira, kunyanya mukugadzirwa kwezvinhu zvinoramba. Refractories yakakosha mumaindasitiri akadai sekugadzira simbi, kwaanoshandiswa kumisa mavira, macrucibles uye molds, pamwe nekugadzirwa kwezvinhu zvinodzivirira kupisa. Indasitiri yerefractory yakachinja zvakanyanya mumakore achangopfuura, kusanganisira kushandiswa kwakapararira kwemagnesia kabhoni zvidhinha uye aluminium kabhoni zvidhinha, zvese zviri zviviri zvine hukama neindasitiri yekugadzira simbi.

Imwe yekushandiswa kukuru kwegraphite iri mukugadzirwa kwezvinhu zvinoramba. Graphite chikamu chakakosha mukugadzirwa kwezvidhinha zvinoramba, zvidhinha, zvinoramba zvichikanda hupfu, cores, molds, detergents, high-temperature resistant materials, etc. Zvinhu izvi zvinoita basa rinokosha mumhando dzakasiyana-siyana dzemaindasitiri, kunyanya mumhizha yesimbi. Inenge 10% yepasirese refractory zvinhu zvinopedzwa neindasitiri yekugadzira simbi, zvichiratidza kukosha kwakakosha kwemagraphite refractories muindasitiri ino.

Kushandiswa kwakapararira kwe magnesia kabhoni zvidhinha mukugadzira simbi yemoto linings ndeimwe yekuchinja kwakakosha muindastiri refractory mumakore achangopfuura. Zvine musanganiswa wemagnesium oxide uye kabhoni, zvidhinha izvi zvine zvakanakisa kupisa kupisa uye zvinogara zvakanyanya, zvichiita kuti zvive zvakanakira kumisa masimbi ekugadzira simbi. Pamusoro pezvo, kushandiswa kwealuminium kabhoni zvidhinha mukuramba kuchikanda kwakaonawo budiriro yakakosha. Izvi zvidhinha zvine aruminiyamu nekabhoni zvakaratidza kuti zvinoshanda mukuramba uchikandira, zvichiratidza kuchinjika uye kuchinjika kwe graphite refractory zvinhu.

Graphite refractory zvinhu zvakabatana zvakanyanya neindasitiri yekugadzira simbi, uye mashandisiro avo uye zvakanakira zvinoonekwa mune ese maficha ekugadzirwa kwesimbi. Kugona kwegraphite kushingirira tembiricha yakakwira uye nehutsinye mamiriro anoita kuti ive chinhu chakanakira machira emoto uye zvimwe zvigadzirwa zvesimbi. Kugara uye kupisa kupisa kwegraphite refractories kunobatsira kuvandudza kushanda uye kuvimbika kwesimbi yekugadzira simbi, pakupedzisira inokanganisa kunaka uye kuenderana kwechigadzirwa chekupedzisira.

Pamusoro pekushandiswa kwayo muindasitiri yekugadzira simbi, graphite ine mabhenefiti akati wandei sechinhu chinoramba. Imwe yemabhenefiti ayo makuru ndeyekupisa kwayo kwepamusoro conductivity, iyo inogonesa kufambisa kupisa kupisa uye kugovera mumaindasitiri maitiro. Ichi chivakwa chinonyanya kubatsira mukushandisa uko kunoenderana tembiricha yakakwira inofanirwa kuchengetedzwa, senge mukugadzirwa kwesimbi uye zvimwe zvinhu zvepamusoro-tembiricha.

Uye zvakare, graphite refractory zvinhu zvinoratidza yakanakisa kugadzikana kwekemikari, zvichiita kuti isarambe ichiita ngura uye kuita kwemakemikari pakupisa kwakanyanya. Munzvimbo dzinogara dzichisangana nemakemikari ane hutsinye uye simbi dzakanyungudutswa, chimiro ichi chakakosha sezvo ichichengetedza hupenyu hurefu uye kuvimbika kweiyo refractory zvinhu.

Imwe bhenefiti yezvigadzirwa zvegraphite kugona kwavo kutsungirira kupisa kwekushisa, kushanduka kamwe kamwe kwekushisa kunogona kukonzera kuti zvinhu zvitsemuka kana kutadza. Kugona kweGraphite kumirisana nekutyisa kwemafuta kunoita kuti ive sarudzo yakavimbika kune maapplication uko tembiricha dzinochinja nekukurumidza, senge mumaindasitiri ekugadzira simbi uye simbi.

Pamusoro pezvo, magraphite refractories anozivikanwa nekuderera kwavo porosity, iyo inobatsira kuwedzera simba ravo uye kugona kuramba kupinda nesimbi yakanyungudutswa nezvimwe zvinhu. Iyi pfuma inonyanya kukosha mumashandisirwo apo kuvhara uye kuvhara kwakakosha, sezvo ichivimbisa kutendeseka kwezvinhu zvinoramba pasi pemamiriro akanyanya.

Kusiyana-siyana kwezvigadzirwa zvegraphite kunowedzera kupfuura kushandiswa kwayo muindasitiri yekugadzira simbi. Graphite refractories inoshandiswawo mumhando dzakasiyana-siyana dzepamusoro-tembiricha yekushandisa, kusanganisira kugadzirwa kweceramics, girazi uye zvimwe zvinhu zvinoda kugadzikana kwekupisa uye kuramba kune yakaoma mamiriro.

mashandisirwo uye zvakanakira zvigadzirwa zvegraphite mukugadzirwa kwezvinhu zvinoramba zvakakosha uye zvinosvika kure. Kushandiswa kwakapararira kwegraphite mukugadzira zvidhinha zvinoramba, macrucibles, kuramba achikandira hupfu, cores uye yakakwirira tembiricha inodzivirira zvinhu zvinoratidzira kukosha kwayo mune dzakasiyana siyana maindasitiri maitiro, kunyanya muindasitiri yekugadzira simbi. Izvo zvichangobva kuitika muindasitiri yerefractory, sekutorwa kwe magnesia kabhoni zvidhinha uye aruminiyamu kabhoni zvidhinha, inowedzera kusimbisa kuchinjika uye kushanda kwe graphite refractory zvinhu. Nekukwirira kwayo kwekushisa kwekushisa, kugadzikana kwemakemikari, kupisa kwekushisa kwekudzivirira uye kuderera kweporosity, graphite inoramba iri sarudzo yekutanga yezvikumbiro zvinoda zvinhu zvinovimbika uye zvakasimba zvinoramba. Sezvo indasitiri iri kuramba ichishanduka uye kudiwa kwezvigadzirwa zvepamusoro-soro, zvigadzirwa zvegraphite zvinozoita basa rakakosha mukuzadzisa izvi zvinodiwa uye kutyaira hunyanzvi mune refractory zvinhu tekinoroji.
