Ezimweni zezimboni zama-tunnel oil kanye nama-pipeline oil, indawo eshisayo ephezulu ifana "nentaba yomlilo" - izingxenye zemishini zidinga ukumelana nokugcatshwa isikhathi eside ngaphezu kuka-800 ℃, kuyilapho futhi zimelana nokuguguleka kwamagesi akhipha i-oxidizing ngisho namagesi ane-acidic. Izinto zensimbi zendabuko zithambekele ekuthambekeni nasekuguqukeni kule ndawo, okuholela ekunciphiseni ngokuzumayo isikhathi sokuphila. Kodwa-ke,induku yokugoqa ye-beam yesikwele eyenziwe nge-silicon carbide (SiC)Izinto zifana “ne-fighter enokushisa okuphezulu”, ethembele ku-gene yayo yokumelana nokushisa, iba “i-sea anchor” yokusebenza okuzinzile kwama-oven anokushisa okuphezulu.
Isizathu sokuthi ama-rollers e-silicon carbide square beam angaba “umdlali we-ace” ensimini yokushisa okuphezulu kungenxa yezakhiwo zawo ezihlukile zezinto:
1. Yakha "isithiyo sokushisa" esakhelwe wena
Uma izinga lokushisa lidlula u-1200 ℃, ifilimu ye-oxide e-silicon dioxide (SiO2₂) ezokwakheka ngokuzenzekelayo phezu kobuso be-silicon carbide. Lolu ngqimba "lwesivikelo esibonakalayo" alukwazi nje ukuhlukanisa umthelela oqondile wokushisa okuphezulu ku-substrate, kodwa futhi lukwazi ukumelana nokungena kwamagesi ane-asidi, kufezwe "ukuvikelwa okubili ekugqwaleni kokushisa okuphezulu".
2. Uma kushisa kakhulu, kuba namandla kakhulu
Ngokuphambene nesici sezinto zensimbi ezithambile lapho zivezwa ekushiseni, i-silicon carbide ayigcini nje ngokugcina amandla ayo okugoba ebangeni lokushisa eliphezulu elingu-800 ℃ -1350 ℃, kodwa futhi ikhombisa ukuthuthuka okuthile. Lesi sici somzimba "sokuphikisana nomkhuba" sivumela ibha ye-roller ukuthi ihlale iqinile ezindaweni zokushisa okuphezulu, igweme ukuwohloka kwesakhiwo okubangelwa ukuthamba.
3. "Inkosi yokuthutha ngokushisa"
Ukushisa kwe-silicon carbide kuphindwe kane kunensimbi, okungasabalalisa ukushisa kwendawo ngokushesha nangokulinganayo “njengomgwaqo omkhulu oshisayo”, kugweme ukuqongelela “kwezindawo ezishisayo” kuhhavini. Lesi sici asivikeli nje kuphela i-roller ngokwayo, kodwa futhi sigcina ukuzinza kokushisa kokusabela kwe-desulfurization, sithuthukise ukusebenza kahle okuphelele.
Yazalelwa izimo zezimboni ezishisa kakhulu
Ukumelana nokushisa okuphezulu kwama-silicon carbide square beam rollers kuwenza avelele kakhulu ezimweni zokushisa okuphezulu njenge-thermal power boilers, i-steel sintering, kanye nokuqhekeka kwamakhemikhali. Ngemva kokusebenzisa lesi sici, amabhizinisi anganciphisa kakhulu imvamisa yokuvalwa nokugcinwa kokushisa okuphezulu, ngenkathi enweba impilo yesevisi yemishini izikhathi eziningana kuneyezinto zendabuko, efinyelela ngempela "ekushiseni okuphezulu ngaphandle kokuvalwa, ukuvikelwa kwemvelo ngaphandle kokupholisa".
Njengebhizinisi elisha eligxile ocwaningweni nasekuthuthukisweni kwezinto zobumba ze-silicon carbide, siyazi kahle izindawo ezibuhlungu zemishini ngaphansi kwezimo zokusebenza ezimbi kakhulu. Yonke i-silicon carbide square beam roller imelela ukuhlola okuphelele kwesayensi yezinto zokwakha. Esikhathini esizayo, sizoqhubeka nokugxila "ekumelaneni nokushisa okuphezulu" njengesiqondiso esiyinhloko sokuthuthuka, futhi sisebenzise amandla obuchwepheshe ukuvikela umugqa wokuvikela oluhlaza wokukhiqiza kwezimboni.
