Kwiimeko zoshishino zee-tunnel oils kunye nee-pipeline oils, indawo enobushushu obuphezulu ifana "nentaba yelangatye" - izixhobo kufuneka zimelane nokugcadwa ixesha elide ngaphezulu kwama-800 ℃, ngelixa zikwamelana nokuguguleka kwee-oxidizing gases kunye nee-asidi gases. Izinto zesinyithi zemveli zinotyekelo lokuthamba kunye nokuguquka kule ndawo, nto leyo ebangela ukuncipha ngequbuliso kwexesha lokuphila. Nangona kunjalo,intonga yerola yomqadi wesikwere eyenziwe nge-silicon carbide (SiC)Izinto ezifana "nomlwi oshushu kakhulu", zixhomekeke kwijini yazo yokumelana nobushushu, zibe "yi-sea anchor" yokusebenza ngokuzinzileyo kwee-ovens ezishushu kakhulu.
Isizathu sokuba iirola ze-silicon carbide square beam rollers zibe "ngumdlali we-ace" kwicandelo lobushushu obuphezulu kungenxa yeempawu zazo ezikhethekileyo zezinto:
1. Yakha "umqobo wobushushu" owakhelwe ngokwakho
Xa ubushushu budlula i-1200 ℃, ifilimu ye-oxide ye-silicon dioxide exineneyo (SiO2₂) iya kwakheka ngokuzenzekelayo phezu komphezulu we-silicon carbide. Olu maleko "lwe-armor transparent" alunakwahlula kuphela impembelelo ethe ngqo yobushushu obuphezulu kwi-substrate, kodwa lukwamelana nokungena kweegesi ze-asidi, nto leyo efezekisa "ukhuseleko oluphindwe kabini nxamnye nokugqwala kobushushu obuphezulu".
2. Okukhona kushushu, kokukhona kusiba namandla ngakumbi
Ngokuchaseneyo nophawu lwezinto zesinyithi ezithamba xa zibekwe kubushushu, i-silicon carbide ayigcini nje ngokugcina amandla ayo egobile kubushushu obuphezulu obuyi-800 ℃ -1350 ℃, kodwa ikwabonisa ukuphuculwa okuthile. Olu phawu "oluchasene nomkhwa" luvumela i-roller bar ukuba ihlale iqinile kwiindawo ezinobushushu obuphezulu, iphephe ukuwohloka kwesakhiwo okubangelwa kukuthamba.
3. "Inkosi yothutho" olushushu
Ukuqhuba kobushushu kwe-silicon carbide kuphindwe kane kunentsimbi, enokusasaza ubushushu bendawo ngokukhawuleza nangokulinganayo njenge "ndlela yobushushu", ithintela ukuqokelelana "kweendawo ezishushu" kwi-oven. Olu phawu alukhuseli nje kuphela i-roller ngokwayo, kodwa lukwagcina uzinzo lobushushu be-desulfurization reaction, luphucula ukusebenza kakuhle ngokubanzi.
Yazalelwa kwiimeko zoshishino ezishushu kakhulu
Ukumelana nobushushu obuphezulu kweerola ze-silicon carbide square beam rollers kuzenza zibalasele ngakumbi kwiimeko zokuchithwa kwesulfurization kubushushu obuphezulu ezifana neebhoyila zamandla obushushu, ukutshiswa kwentsimbi, kunye nokuqhekeka kweekhemikhali. Emva kokusebenzisa eli candelo, amashishini anokunciphisa kakhulu ukuphindaphinda kokuvalwa nokugcinwa kobushushu obuphezulu, ngelixa endisa ubomi benkonzo yezixhobo ukuya kuthi ga kwiindlela ezininzi kunezo zemveli, ngokwenene efikelela "kubushushu obuphezulu ngaphandle kokuvalwa, ukhuseleko lokusingqongileyo ngaphandle kokupholisa".
Njengeshishini elitsha eligxile kuphando nophuhliso lwezinto ze-silicon carbide ceramic, siyazi kakuhle iindawo ezibuhlungu zezixhobo phantsi kweemeko zokusebenza eziqatha. Yonke i-silicon carbide square beam roller imele uphando olupheleleyo lwesayensi yezinto. Kwixesha elizayo, siza kuqhubeka sigxila "ekuchaseni amaqondo obushushu aphezulu" njengeyona ndlela iphambili yokuphumelela, kwaye sisebenzise amandla etekhnoloji ukukhusela umgca wokhuselo oluhlaza wemveliso yemizi-mveliso.
