Wadanne nau’ikan kayan rufewar tanderun ne?
Menene nau’ikan injin wuta kayan rufi?
Induction kayan rufin tanderu kuma ana kiransa kayan murɗa murhun wuta, busasshen busassun kayan girgiza wuta, kayan kullin tanderun induction, kayan murɗa tanderu, kasu kashi acidic, tsaka tsaki, da kayan rufin alkaline. Ana yin kayan rufi na acidic da ma’adini mai tsabta, narkakkar ma’adini shine babban kayan albarkatun kasa, ana amfani da abubuwan da aka haɗa a matsayin wakili na sintering; da tsaka tsaki tanderun rufi kayan da aka yi da alumina da high aluminum kayan a matsayin babban albarkatun kasa, da kuma hadaddiyar da aka yi amfani da a matsayin sintering wakili; An yi amfani da kayan rufin tander na asali na corundum mai tsafta mai tsafta da kuma tsaftataccen wutar lantarki Fused magnesia da kashin kashin baya mai tsabta ana amfani da su azaman babban kayan albarkatun ƙasa, kuma ana amfani da abubuwan ƙari masu haɗaka azaman sinadari.
Akwai nau’ikan induction nau’ikan rufin tanderu iri uku. Ɗayan shine rufin acidic, wanda aka samo shi ta hanyar busassun ramming na yashi ma’adini, kuma wakili na haɗin gwiwa shine borax ko boric acid; ɗayan busassun ramming da gyare-gyaren magnesia, kuma ma’aunin haɗin gwiwa shine borax ko boric acid. Daya shine rufin tanderu mai tsaka-tsaki, wanda aka rago kuma an samo shi daga babban alumina bauxite clinker. A cikin ‘yan shekarun nan, tare da haɓakar fasaha da bullowar sabbin kayayyaki iri-iri, sabbin kayan rufi da yawa suma sun bayyana a cikin kayan rufewar tanderu.
1. Ruwan acid
Rufin tanderun acidic shine yashi ma’adini, wanda ke da arha, rarrabawa ko’ina, rufi mai kyau, ƙarancin buƙatun gini, ƙarancin lahani yayin amfani, da ingantaccen samarwa. Koyaya, yashin ma’adini yana da ƙarancin refractoriness kuma ba zai iya biyan buƙatun manyan tanderun shigar da kaya ba. Kuma akwai canjin lokaci na biyu a lokacin aikin dumama, daidaitaccen kwanciyar hankali ba shi da kyau, daidaiton sinadarai ba shi da kyau, kuma kawai yana amsawa tare da slag don samar da lalata. Don hana waɗannan lahani, ana iya amfani da ma’adini mai fused. Abin da ke ciki yana da girma, abun ciki na silicon dioxide ya fi 99%, refractoriness yana ci gaba sosai, kusa da wurin narkewa, kuma babu wani canji na biyu a lokacin dumama, babu canjin yanayin dumama, kuma girgizawar thermal ta kasance barga. . Jima’i kuma ya ci gaba sosai.
2. Rubutun tsaka tsaki
Ana amfani da gaurayawan corundum azaman rufin tanderun shigar da shi. Domin ma’anar narkewar farin corundum yana da girma kamar 2050 ℃, taurin yana da girma kamar 8. Yana da juriya, juriya mai zafi, kuma yana da kwanciyar hankali fiye da ma’adini. Ya dace da simintin ƙarfe mai zafin jiki ko babban rufin tanderu. Siffar ita ce kuma tana da lahani na canjin lokaci da babban haɓakar haɓakar thermal. A cikin aikace-aikacen, sa hannu na foda na spinel zai iya haɓaka juriya na lalata da daidaitattun daidaito.
3. Ruwan alkaline
Rufin tanderun al’ada na al’ada yana samuwa ta hanyar busassun ramming na magnesia. A amfani ne high refractoriness, kusa da 2800 ℃, da lahani ne cewa fadada coefficient ne babba, sauki crack, da magnesia rufi ne lalata resistant, tsawon rai, low price, kuma shi ne yadu amfani. Shiga cikin farin corundum foda ko spinel foda yana inganta rayuwar sabis.
4. Rufin kashin baya
Rubutun kashin baya sabon nau’in kayan rufi ne. An ƙera shi daga alumina da magnesia, ana harba shi a babban zafin jiki ko kuma an riga an yi shi cikin kashin baya ta hanyar haɗin wutar lantarki, sannan ya samar da ma’auni daban-daban kamar yadda ake buƙata. Ana amfani da shi azaman rufin tanderun shigar da wutar lantarki, kuma wakili na haɗin gwiwa yana nan Zaɓin borax ko boric acid yana da fa’idodin farin murhun murhun murhu da rufin tanderun magnesia, tare da hana lahani. Ita ce jagorancin ci gaba na babban rufin tanderun shigar da wutar lantarki da kuma rufin tanderu mai zafi. Yawancin kayan rufin tanderun da aka shigo da su na irin wannan.
5. Sabbin fasaha da sababbin kayan aikin kayan rufi na tanderun
① Shiga cikin matsananci-lafiya foda (mafi yawa a cikin ‘yan microns) a gargajiya tanderun rufi kayan, wanda zai iya inganta lalata juriya da thermal buga kwanciyar hankali na makera rufi kayan, kamar silica micro foda, alumina micro foda, farin corundum micro foda, spinel micro foda, da dai sauransu.
②Busashen gyare-gyare. Tushen tanderu na gargajiya duk ana samun su ta busasshen foda da busassun ramming. Lalacewar shine yana da sauƙin yin chromatograph kuma ya zama lahani kamar fanko. A cikin hanyar bushewa, 2% zuwa 3% hadawar ruwa ana amfani dashi don rage chromatography, kuma amincin yana da kyau, kuma ba zai haifar da lahani da yawa ba. Yana buƙatar ɗan tsayi kaɗan kawai a cikin tanda mai ƙarancin zafi.
③ Tsarin gyare-gyare na rabin-bushe yana shiga cikin siminti mai tsabta na calcium aluminate, tare da rufin tanderu mai tsabta ko tsaka tsaki; yayin da yake cikin rufin tanderun alkaline, yana shiga cikin magnesium oxide, sodium hexametaphosphate, da sauransu.
