Chrome Corundum Brick
Chrome Corundum Brick
1. Hakanan ana kiran bulo na corundum na Chrome babban ƙarfe mai jurewa na chromium corundum tapping tubalin tashar. Babban samfuri ne wanda kamfaninmu ya inganta zuwa kasuwa a cikin ‘yan shekarun da suka gabata. An hada shi daga tsarkakakken alumina Al2O3 da chromium oxide Cr2O3 azaman manyan albarkatun ƙasa. Idan aka kwatanta da tubalin corundum mai tsafta, yana da kyawawan kaddarorin, kamar ƙanƙantar da kai da taɓarɓarewa a ƙarƙashin nauyi. Zazzabi, ƙarfin lanƙwasa, babban zazzabi mai rarrafe, daidaiton ƙarar zafin zafin jiki da juriya na lalata lalata.
2. An fi amfani da shi don mirgina shingen murhun murhun ƙarfe na ƙarfe da dandamali, bututun ruwa, da sauran sassa na tanderun masana’antu. Bulo na corundum na Chrome wani nau’in abu ne mai ƙin ƙima, kuma rayuwar sabis na iya kaiwa watanni 10 zuwa 18 bayan yawancin masu amfani da injin daskarewa.
3. Aikace-aikacen yana nuna cewa ana amfani da tubalin tashar chromium corundum taɓarɓarewar tubalin tashar tashar tashar murɗawa don dumama manyan akwatunan sashe, babban gogayya ta yanki ɗaya da babban fitarwa, wanda ba kawai zai iya ƙara tsawon rayuwar sabis na tapping channel, da rage tsayawa. Lokacin wutar makera, haɓaka samarwa, rage yawan kuzari da kashe kuɗaɗen kulawa, da rage yawan saurin sanyaya da dumama saboda rufe murhu don kiyayewa, don inganta rayuwar tanderun gabaɗaya, kuma fa’idodin tattalin arziƙi na iya zama samu. 4. Yin amfani da α-Al2O3 azaman albarkatun ƙasa, ƙara adadin da ya dace na chromium oxide foda da ingantaccen chromium corundum clinker foda, bayan kafawa, nutsewa a babban zafin jiki. Abubuwan da ke cikin chromium oxide na sinadarin burodi mai ƙarfi na chromium gaba ɗaya sun fi na tubalin da aka haɗa da chromium corundum. Hakanan ana iya shirya shi ta hanyar yin simintin gyare -gyare. Fushin α-Al2O3 da foda na chromium oxide suna haɗe-haɗe, kuma ana ƙara manne da madogarar ƙira don yin kauri mai kauri. A lokaci guda, ana ƙara ɓangaren chromium corundum clinker, kuma ana yin bulo ta hanyar tsagewa. Wuta kuma. Ana iya amfani dashi azaman rufin murhun gilashi, tubalin murfin ramin kwararar gilashin zane da goyan bayan na’urar yin gyaran ƙarfe mai zafi, ƙona shara, ƙona ruwa mai matse gas, da dai sauransu.
5. Samfura masu ƙyalƙyali tare da abun ciki na alumina mafi girma fiye da 90% da corundum a matsayin babban matakin crystal. Matsanancin matsanancin zafin zafin zafin jiki (har zuwa 340MPa). Babban zazzabi mai laushi yana farawa zafin jiki (fiye da 1700 ° C). Kyakkyawan kwanciyar hankali na sinadarai, juriya mai ƙarfi ga acidic ko alkaline slag, ƙarfe da gilashin ruwa. Karfin girgizawar zafi yana da alaƙa da tsarin sa. Tsarin juriya na samfuran mai yawa yana da kyau, amma kwanciyar hankali na girgiza mara kyau. Akwai tubalin corundum na sintered iri biyu da tubalin corundum fused. Za a iya amfani da alumina da aka haɗa da fuskokin corundum azaman kayan albarkatun ƙasa, ko bauxite clinker tare da babban rabo na Al2O3/SiO2 za a iya haɗa shi da sinadarin alumina da aka yi ta hanyar nutsewa. Hakanan ana iya amfani da acid phosphoric ko wasu wakilan haɗin gwiwa don yin tubalin corundum mara ƙonewa.
6. Anyi amfani da shi sosai a cikin murhun ƙarfe na ƙarfe da murhun tanderu mai ƙona wuta, tsaftace tanderu a waje da tukunyar ƙarfe, masu ɗebo ruwa, gilashin narkar da gilashi da tanderun masana’antu na petrochemical. Ana amfani da bulo na Corundum a cikin rufi na ɗimbin ɗimbin ɗimbin ɗimbin ɗimbin zafi da kayan dafa abinci a cikin masana’antun man fetur da taki, kamar fasawa, gyaran tanderu, da masana’antun ƙarfe.
7. Alamomin jiki da sinadarai
