Imathiriyeli ephikisayo
ingcamango:
Iklasi yemathiriyeli ye-inorganic non-metallic ene-refractoriness engekho ngaphantsi kwe-1580 ° C.I-Refractoriness ibhekisela kwiqondo lokushisa kweCelsius apho isampuli ye-cone ye-refractory imelana nesenzo sokushisa okuphezulu ngaphandle kokuthamba kunye nokunyibilika phantsi kwemeko yokungabikho komthwalo.Nangona kunjalo, kuphela inkcazo ye-refractoriness ayikwazi ukuchaza ngokupheleleyo izinto eziphikisayo, kwaye i-1580 ° C ayikho ngokupheleleyo.Ngoku ichazwa njengazo zonke izinto ezinomzimba kunye neekhemikhali ezivumela ukuba zisetyenziswe kwindawo yokushisa ephezulu zibizwa ngokuba yizinto eziphikisayo.Izinto ezichasayo zisetyenziswa ngokubanzi kwisinyithi, kushishino lweekhemikhali, i-petroleum, ukwenziwa koomatshini, i-silicate, amandla kunye namanye amashishini.Zizona zikhulu kwishishini le-metallurgical, zibalelwa kwi-50% ukuya kwi-60% yesiphumo esipheleleyo.
isiphumo:
Izinto ezixhathisayo zisetyenziswa kwiinkalo ezahlukeneyo zoqoqosho lwesizwe njengentsimbi, isinyithi, isinyithi, isinyithi, i-samente, i-ceramics, i-petrochemicals, oomatshini, iibhoyila, ishishini lokukhanya, amandla ombane, ishishini lomkhosi, njl. ukuqinisekisa ukusebenza kwemveliso kunye nophuhliso lobuchwepheshe lwala mashishini angasentla.Idlala indima ebalulekileyo nengenakuphinda ithathelwe indawo kuphuhliso lwemveliso yemizi-mveliso enobushushu obuphezulu.
Ukusukela ngo-2001, iqhutywa luphuhliso olukhawulezayo lwamashishini aphezulu obushushu anjengentsimbi kunye nentsimbi, isinyithi esingenamvubelo, iikhemikhali zepetroli, kunye nezixhobo zokwakha, ishishini le-refractory liye lagcina ukukhula okulungileyo kwaye liye laba ngumvelisi omkhulu kunye nomthengisi wezinto eziphikisayo kwi-refractory. ihlabathi.Ngo-2011, imveliso ye-refractory yase-China yabalelwa malunga ne-65% yelizwe lonke, kwaye imveliso yayo kunye nomthamo wokuthengisa ngokuthe ngcembe ubekwe kwindawo yokuqala emhlabeni.
Uphuhliso loshishino oluxhathisayo lunxulumene ngokusondeleyo nokugcinwa kwezimbiwa zasekhaya.I-Bauxite, i-magnesite kunye ne-graphite zezona zixhobo zithathu zi-refractory.ITshayina lelinye lamazwe amathathu athumela ibauxite kumazwe angaphandle, elona candelo logcino lwemagnesite, kunye nomthengisi omkhulu wegraphite.Izibonelelo ezityebileyo ziye zaxhasa izinto zaseTshayina ezichasayo kwishumi leminyaka lophuhliso olukhawulezayo.
Ngexesha "leSishumi elineSibini seMinyaka emiHlanu", iChina ikhawulezisa ukupheliswa kwamandla aphelelwe lixesha kunye nomthamo ophezulu wokuvelisa amandla.Eli shishini liza kugxila kuphuhliso kunye nokukhuthaza amaziko amatsha okonga umbane, uphuhliso lobuchwepheshe bokugcina umbane, ulawulo lwamandla, ulawulo lokukhutshwa kwenkunkuma “yenkunkuma emithathu” kunye nokusetyenziswa kwemithombo “yenkunkuma emithathu” yokuRisayikilishwa, njl.njl. ukusetyenzwa kwakhona kobutyebi kunye nokusetyenziswa kwakhona kwemathiriyeli echasayo emva kokusetyenziswa, ukunciphisa ukukhutshwa kwenkunkuma eqinileyo, ukuphucula ukusetyenziswa okubanzi kwemithombo yobutyebi, kunye nokukhuthaza ngokubanzi ukugcinwa kwamandla kunye nokunciphisa ukukhutshwa.
"I-Refractory Industry Development Policy" ibonisa ukuba iyunithi yokusetyenziswa kwezinto eziphikisayo kwishishini lensimbi yaseChina malunga neekhilogram ezingama-25 ngetoni nganye yentsimbi, kwaye iya kuwela ngaphantsi kweekhilogram ezili-15 ngo-2020. Ngo-2020, iimveliso ze-refractory zaseChina ziya kuhlala ixesha elide. , ukonga amandla ngakumbi, akukho ngcoliseko, kwaye iyasebenza.Iimveliso ziya kuhlangabezana neemfuno zophuhliso loqoqosho lwesizwe ezifana nesinyithi, izinto zokwakha, iikhemikhali, kunye namashishini asakhulayo, kwaye ziya kwandisa umxholo wobugcisa weemveliso ezithunyelwa ngaphandle.
Izinto eziphikisayo zineentlobo ezininzi kunye nokusetyenziswa okuhlukeneyo.Kuyimfuneko ngokwenzululwazi ukwahlula izixhobo ezichasayo ukuququzelela uphando lwenzululwazi, ukhetho olunengqiqo kunye nolawulo.Zininzi iindlela zokuhlela izinto eziphikisayo, kubandakanywa ulwahlulo lweempawu zekhemikhali, ulwahlulo lwemichiza yeeminerali, ulwahlulo lwenkqubo yokuvelisa, kunye nokuhlelwa kwezinto ezibonakalayo.
