Ukuqhathanisa impilo yesevisi ngaphambi nangemva kokuguqulwa kophahla lwesithando sokushisa esishisayo

I-steel rolling heat furnace yisithando somlilo sezimboni esishisisa izinto zokwakha noma imikhiqizo yensimbi yensimbi ekushiseni okukhangayo. Uphahla lwesithando somlilo luyingxenye ebalulekile yesithando somlilo sensimbi. Ngakho-ke, uma kunenkinga ngophahla lwesithando somlilo kwamanye amabhizinisi okwenza insimbi, ngeke nje kulethe Ukupholisa nokulungisa, noma kumise ngisho nokukhiqiza.

Okokuqala, singaqiniseka ukuthi ngemva kokusetshenziswa isikhathi eside kwesithando somlilo sokushisa insimbi, uphahla lwesithando somlilo luzowa ezindaweni ezinkulu izikhathi eziningi, futhi ngeke lusize ngemva kokulungiswa. Imvamisa, uphahla lwesithando somlilo lungase lushiswe futhi amalangabi angaphumela ngaphandle, okubangela ukuba inkampani iphoqeleke ukuba iphole futhi ilungise. Ezimweni ezibucayi kakhulu, misa isithando somlilo ngokuqondile, futhi izinga lokushisa langaphandle lesigaba sokushisa kanye nesigaba sokucwiliswa kwesithando somlilo siphezulu, ngesilinganiso esingu-230 ° C, futhi izinga lokushisa lasendaweni liphezulu njengo-300 ° C.

Problems with the stove top

1. Ijika eliphezulu lesithando sokushisa liwuhlobo lwe-multi-stage choke, (njengoba kuboniswe emfanekisweni ongezansi), kunezinyosi eziningi ze-zigzag. Izinguquko ejikeni eliphezulu ngokuvamile ama-engeli angakwesokudla, kanti ezinye izingxenye zingama-engeli ashubile. Lapho izinga lokushisa liphakanyiswa futhi lehliswa, kulula ukubangela i-engeli elungile. , Ukugxila kwengcindezi kuma-engeli acute kubangela ukuqhekeka nokuchitheka.

2. Isakhiwo sezitini esiphikisayo se-anchor asinangqondo. Ezinye izingxenye (indawo emaphakathi yophahla lwesithando somlilo) zinophahla olushubile kanye nesisindo esisindayo, kodwa kunezitini ezimbalwa zehange, okwenza uphahla lwesithando liwe lula ngemva kokuqhekeka.

3. Ukucindezeleka kwama-zigzag ophahleni lwesithando somlilo kuyisici esiqinile esiphikisayo sophahla lwesithando somlilo, okuyisixhumanisi esibuthakathaka sophahla lwesithando somlilo, kodwa silenga ngokuqondile ngaphandle kwezitini zokubambelela, okwenza uphahla lwesithando somlilo lube lula. Ukugoqa kubi.

4. The setting of the furnace roof expansion joint is unreasonable. The cross section of the roof of the heating furnace is bow-shaped, and the roof span is 4480mm. However, the original furnace roof only has horizontal expansion joints and no longitudinal expansion joints, which leads to multiple irregular longitudinal cracks in the furnace roof. The depth of the cracks generally penetrates the entire thickness of the furnace roof, which makes the furnace roof prone to local collapse.

5. Idizayini yesendlalelo sokuvala uphahla lwesithando somlilo ayinangqondo, ungqimba kuphela lwezitini zobumba ezikhanyayo ezingama-65mm, ezinokusebenza okuphezulu kokushisa, okungavalwanga ngokuqinile, kanye nomphumela ongemuhle wokushisa ukushisa.

6. Ingaphezulu lesithando somlilo lifakwe ngezinsimbi ezisezingeni eliphezulu nezinamandla aphezulu. Umkhiqizo ucwaningiwe futhi wathola ukuthi amandla ayo okushisa okuphezulu, ukuzinza kokushaqeka kokushisa nokunye ukusebenza kokushisa okuphezulu akukuhle, okwenza uphahla lwesithando somlilo luhlale luwa, okwenza izinga lokushisa lodonga lwangaphandle lophahla lwesithando ludlule ejwayelekile.

7. The flat flame burner on the top of the furnace will accelerate its damage due to the bad use conditions, insufficient fuel and air mixing, poor combustion quality, and poor energy-saving effect.

Isixazululo sokuthuthukisa:

1. Shintsha ama-engeli angakwesokudla nama-acute ophahleni lwesithando somlilo abe amakhona ayindilinga angu-R30 ° ukuze unciphise ukuqhekeka nokuwa okubangelwa ukugxila ekucindezelekeni ngesikhathi sokushisa nokupholisa. (njengoba kuboniswe esithombeni 2)

Hlela ngokunengqondo izitini zehange, engeza isitini sehange engxenyeni emaphakathi yophahla lwesithando esishubile futhi kulula ukuwa, futhi usabalalise ngokulinganayo eduze kophahla lwesithando somlilo ukwandisa amandla ophahla lwesithando somlilo futhi unciphise amathuba okuwa. engxenyeni emaphakathi yophahla lwesithando somlilo.

2. Hambisa “i-sawtooth” phansi ingxenye yesithando somlilo phezulu ngo-232mm sisonke, bese usebenzisa izitini ezinwetshiwe zehange engxenyeni engezansi. Ngemuva kokuthi uhlobo lwe-“saw-tooth” lucindezelwe phansi futhi luqhubekele phambili, izitini zehange ezinwetshiwe zisebenza ngokuqondile engxenyeni ewugqinsi yophahla lwesithando somlilo engxenyeni ecindezelweyo, okuthuthukisa amandla aphelele engxenye ecindezelwe yophahla lwesithando somlilo futhi igweme ukuwa. lapha.

3. Engeza ijoyinti yokukhulisa ubude enobubanzi obungu-8mm phakathi kwezitini ezimbili eziseduze eziseduze phakathi kophahla lwesithando ukuze ukhulule ukugxiliswa kokucindezeleka kwezinto eziphikisayo ophahleni lwesithando somlilo ngesikhathi sokuncibilika kokupholisa nokwandiswa kokushisa, futhi ugweme ukuqhekeka kwe-longitudinal.

4. Uphahla lwesithando somlilo luthatha isakhiwo se-thermal insulation esiyinhlanganisela, esihlanganiswe eduze nodonga lwangaphandle lophahla lwesithando somlilo. Imbozwe izendlalelo ezimbili ze-aluminium silicate fiber blanket ezine-conductivity ephansi yokushisa kanye nobukhulu obungama-20mm, futhi ungqimba lwezitini zobumba olukhanyayo olunobukhulu obungu-65mm lubekwe phezu koqweqwe lwangaphandle. .

5. Sebenzisa izinto ezithembekile ezizigelezayo, ezomisa ngokushesha, ezikwazi ukuqhuma esikhundleni sezinsimbi ezisezingeni eliphezulu nezinamandla aphezulu. Lokhu ku-castable kulungele ngokukhethekile ukuthululwa kweziqongo zesithando somlilo ezimise okwe-bow. Ingasebenzisa amandla ayo adonsela phansi ukuze iphume ngaphandle kokudlidliza ukuze ifinyelele ukuminyana. Ukuze uvimbele isitini sokubambelela ukuze singaphambuki noma siphulwe ukudlidliza. Ngesikhathi esifanayo, i-castable ine-porosity ephansi, ukuzinza okuhle kokuthuthumela kwe-thermal, amandla amahle ezinga lokushisa eliphezulu, nokusebenza okuhle kakhulu kwezinga eliphezulu lokushisa.

6. Khetha isibasi selangabi esiyisicaba esonga amandla. Lesi sishisi sinesimo esihle sokwandisa ukugeleza komoya, umphumela omuhle wokunamathiselwe odongeni, ukuxubana kwamafutha afanayo nomoya, kanye nokuvutha okugcwele, okungaqinisa ngokuphumelelayo inqubo yokudlulisa ukushisa esithandweni futhi kwandise ukudluliswa kokushisa okukhazimulayo.

Ngokuqulwa kwecala, indawo engaphezulu yesithando somlilo esiginqikayo yensimbi ayisusanga nje kuphela iphutha, kodwa futhi yandisa impilo yesevisi, ukufeza injongo yokonga amandla nokunciphisa ukusetshenziswa. Ikakhulukazi, ukusetshenziswa kwama-castables azigelezayo kuthambile kakhulu, ukusebenza okuzinzile, futhi akukho ukuchithwa okuvamile okwenzeka futhi. Ukuhlangabezana nezidingo zokukhiqiza, ngaleyo ndlela futhi kuthuthukise indawo yokusebenza.
