Ukuthelekiswa kobomi benkonzo ngaphambi nangemva kohlaziyo lwentsimbi yokufudumeza uphahla lweziko

Steel rolling ukufudumeza eziko yi eziko kushishino ukufudumeza izinto okanye iimveliso zentsimbi workpiece ukuya ubushushu forging. Uphahla lwesithando somlilo luyinxalenye ebalulekileyo yesithando somlilo. Ngoko ke, ukuba kukho ingxaki kuphahla lweziko lamanye amashishini okwenza intsimbi, akuyi kuzisa kuphela i-Cool down kunye nokulungiswa, okanye ukuyeka ukuvelisa.

Okokuqala, sinokuqiniseka ukuba emva kokusetyenziswa kwexesha elide lesithando sokufudumala somlilo, uphahla lwesithando somlilo luya kudilika kwiindawo ezinkulu ngamaxesha amaninzi, kwaye aluyi kunceda emva kokulungiswa. Ngokuqhelekileyo, uphahla lwesithando somlilo lunokutshiswa kwaye amadangatye angaphuma ngaphandle, okubangela ukuba inkampani iphole kwaye ilungise. Kwiimeko ezinzulu kakhulu, misa isithando somlilo ngokuthe ngqo, kunye nokushisa kwendawo yangaphandle yecandelo lokufudumeza kunye necandelo lokucwiliswa kwesithando somlilo liphezulu, kunye ne-avareji ye-230 ° C, kwaye ukushisa kwendawo kuphezulu kwi-300 ° C.

Iingxaki nomphezulu wesitovu

1. I-curve ephezulu yesithando sokufudumala luhlobo lwe-multi-stage choke, (njengoko kuboniswe kumfanekiso ongezantsi), kukho ezininzi zokudakumba kwe-zigzag. Utshintsho kwigophe eliphezulu ubukhulu becala zii-engile ezichanekileyo, kwaye amanye amalungu zii-engile ezibukhali. Xa ubushushu buphakanyisiwe kwaye buhla, kulula ukubangela i-angle echanekileyo. , Ukugxininiswa koxinzelelo kwii-angles ezibukhali kubangela ukuqhekeka kunye nokuchithwa.

2. Uyilo lwezitena eziqhankqalazayo alunangqiqo. Ezinye iindawo (ummandla osembindini wophahla lwesithando somlilo) unophahla olungqindilili kunye nobunzima obunzima, kodwa kukho izitena ezimbalwa ze-ankile, ezenza uphahla lwesithando somlilo lube lula ukuwa emva kokuba kwenzeke iintanda.

3. Ukuxinezeleka kwe-zigzag yophahla lwesithando somlilo yimpahla enqabileyo ye-refractory yophahla lwesithando somlilo, esisikhonkco esibuthathaka sophahla lwesithando somlilo, kodwa sixhonywe ngokuthe ngqo ngaphandle kwezitena ze-anchoring, okwenza uphahla lwesithando somlilo lube lula ukuwa. Ukuwa kunzulu.

4. Ukumiselwa kwejoyinti yokwandiswa kophahla lwesithando somlilo akunangqiqo. Inxalenye yesiphambano sophahla lwesithando somlilo sifana nesaphetha, kwaye ubude bephahla buyi-4480mm. Nangona kunjalo, uphahla lokuqala lwesithando somlilo lunamalungu okwandisa othe tye kuphela kwaye akukho malungu okwandisa ubude, nto leyo ekhokelela kwiintanda ezininzi ezingaqhelekanga zelongitudinal kuphahla lwesithando somlilo. Ubunzulu beentanda ngokubanzi bungena kwi-thickness yonke yophahla lwesithando somlilo, okwenza uphahla lwesithando somlilo luxhomekeke ekuweni kwendawo.

5. Uyilo lophahla lophahla lwesithando somlilo alunangqiqo, kuphela umaleko wezitena zodongwe ezityebileyo ezingama-65mm, ezinomgangatho ophezulu we-thermal conductivity, ongatywinwanga ngokuqinileyo, kunye nefuthe elibi lokufudumala ubushushu.

6. Umphezulu wesithando somlilo uphoswe ngobushushu obuphezulu kunye nomgangatho ophakamileyo. Imveliso iye yaphandwa kwaye yafumanisa ukuba amandla ayo obushushu obuphezulu, ukuzinza kwe-thermal shock kunye nokunye ukusebenza okuphezulu kobushushu akulunganga, okubangela ukuba uphahla lwesithando somlilo luhlale luwa, lubangela ukuba ubushushu bodonga lwangaphandle lophahla lwesithando ludlule. umgangatho.

7. I-flame flame burner phezulu kwesithando somlilo iya kukhawuleza umonakalo wayo ngenxa yeemeko zokusetyenziswa kakubi, i-fuel eyaneleyo kunye nokuxubana komoya, umgangatho womlilo ophantsi, kunye nefuthe elibi lokulondoloza amandla.

Isisombululo sokuphucula:

1. Guqula i-engile echanekileyo kunye ne-acute yophahla lwesithando somlilo ukuya kwi-R30 ° iikona ezijikelezileyo ukunciphisa ukukrazula kunye nokuwa okubangelwa kugxininiso loxinzelelo ngexesha lokufudumeza kunye nokupholisa. (njengoko kubonisiwe kumfanekiso wesi-2)

Ukulungelelanisa ngokufanelekileyo izitena ze-ankile, yongeza isitena se-ankile kwindawo esembindini wophahla lwesithando somlilo esityebileyo kwaye kulula ukuwa, kwaye usasaze ngokulinganayo kunye nophahla lwesithando somlilo ukwandisa amandla ophahla lwesithando somlilo kunye nokunciphisa amathuba okuwa. kwindawo esembindini wophahla lweziko.

2. Hambisa i-“sawtooth” ezantsi inxalenye yesithando somlilo umphezulu we-232mm iyonke, kwaye usebenzise izitena ze-ankile ezongeziweyo kwindawo esezantsi. Emva kokuba uhlobo lwe “saw-tooth” lucinezelwe phantsi kwaye luqhubele phambili, izitena ze-ankile ezide zisebenza ngokuthe ngqo kwindawo engqindilili yophahla lwesithando somlilo kwindawo ecinezelweyo, ephucula amandla apheleleyo ecandelo elicinezelweyo lophahla lwesithando somlilo kwaye ugweme ukuwa. Apha.

3. Yongeza i-longitudinal yokwandisa i-longitudinal kunye nobubanzi be-8mm phakathi kwezitena ze-anchor ezimbini ezisondeleneyo phakathi kophahla lwesithando somlilo ukukhulula uxinzelelo loxinzelelo lwezinto eziphikisayo kuphahla lwesithando somlilo ngexesha lokupholisa kunye nokwandiswa kokufudumala, kwaye ugweme ukuqhekeka kwe-longitudinal.

4. Uphahla lwesithando somlilo luthatha i-composite thermal insulation structure, ehlanganiswe ngokusondeleyo eludongeni lwangaphandle lophahla lwesithando somlilo. Ihlanganiswe ngeengubo ezimbini ze-aluminium silicate fiber blankets kunye ne-low conductivity ye-thermal kunye nobukhulu be-20mm, kunye noluhlu lwezitena zodongwe olukhanyayo kunye nobukhulu be-65mm lubekwe kwinqanaba elingaphandle. .

5. Sebenzisa i-self-flowing ethembekileyo, eyomisa ngokukhawuleza, i-castable-proof-proof castables endaweni yokushisa okuphezulu kunye nokuqina okuphezulu. Le nto yokuphosa ifaneleke ngokukhethekileyo ukugalelwa kweentloko zesithando somlilo. Inokusebenzisa umxhuzulane wayo ukuba impompoze ngaphandle kokungcangcazela ukuze ifezekiseke. Ukuthintela isitena sokubambelela ukuba singaphambuki okanye siphulwe kukungcangcazela. Kwangaxeshanye, i-castable ine-porosity ephantsi, uzinzo oluhle lomothuko we-thermal, amandla amahle obushushu obuphezulu, kunye nokusebenza okuphezulu kobushushu obuphezulu.

6. Khetha isitshisi somlilo esicaba esisicaba. Esi sitshisi sinesimo esihle sokwandiswa kwe-airflow, isiphumo esihle sokunamathisela udonga, i-fuel efanayo kunye nokuxuba umoya, kunye nokutsha okupheleleyo, okunokuqinisa ngokufanelekileyo inkqubo yokudlulisa ubushushu kwisithando somlilo kunye nokwandisa ukutshintshwa kobushushu obukhanyayo.

Ngovavanyo, umphezulu wentsimbi yokufudumeza isithando somlilo awugcini nje ukucima iphoso, kodwa wandisa ubomi benkonzo, ukuphumeza injongo yokonga amandla kunye nokunciphisa ukusetyenziswa. Ngokukodwa, ukusetyenziswa kwee-self-flow castables kubuthathaka kakhulu, ukusebenza okuzinzileyo, kwaye akukho kuchithwa rhoqo okwenzekayo kwakhona. Ukuhlangabezana neemfuno zemveliso, ngaloo ndlela kuphuculwe indawo yokusebenza.
