Process kuyerera simbi pombi quenching uye tempering kugadzirwa mutsetse

Zvakangofanana neyakajairwa gasi kudziyisa choto chekufamba, asi iyo nheyo yekushanda uye kugadzira engineering zvakasiyana zvachose. Muchoto chekufamba-gasi, pombi yesimbi inopisa zvachose; uri mu induction kupisa chira, pombi yesimbi inoramba ichipisa nhanho nhanho; nzira yekudzima uye kupisa kunoitwa nenzira imwecheteyo. Naizvozvo, kana pombi yesimbi ichipisa, yakadzimwa, uye yakapfava, inongofamba kureba uye nemhepo, uye imwe yese inofambiswa nedivi. Iyo chaiyo yekugadzirisa maitiro ndeaya anotevera: Zvinoenderana nekudzimisa uye kupisa zvinodiwa zveAPI 5 CT chiyero chepombi yemafuta epombi, mabheji epombi emafuta anosimudzwa kubva pamusoro pecrane kuenda papuratifomu yekurodha, uye mushure mekutariswa kwechitarisiko chemaoko, iwo anoiswa. yakarongedzwa zvakanaka uye yakagoverwa. Kana imwe neimwe nzvimbo yebasa remutsetse wekugadzira ichipinda munzvimbo yakajairika yekushanda, sensor inopihwa simba rekumirira izvo, iyo inochinja frequency feeder inotanga kutenderera, uye inotsika yekudyisa inoshandiswa nemaoko kuti isimudze pombi yekutanga yemafuta kubva pakubuda. kupera kwechikuva chekudyisa. Iyo inotumirwa kune roller tafura yemuchina wekugadzirisa, uye frequency yekushandura feeder inodyisa kumberi nekumhanya kwakaiswa. Iyo frequency conversion feeder idhiraivha imwe chete ine inochinjika kumhanya uye kureba. Rudzi rwe roller inonyatso gadzirwa roller feeder ine yakarerekera 15 ° kurongeka. Horizontal feeding kugadzirisa centering uye workpiece self-rotation function. Iyo yekudyisa roller pakati peiyo induction heat coils uye yekudyisa roller pane inopinza uye yekubuda inogadzirwa nesimbi isingadziviriri kupisa, uye yakashongedzerwa neinotenderera yakavharirwa mukati memvura yekutonhodza mudziyo wekutonhodza roller yekudyisa uye kugadzira kunze kweiyo yekudyisa roller Kuomesa. inofambisa kupisa kunoramba kuchipisa kwetubhing, uye imwe yakasara yefeed roller inogadzirwa nesimbi isingachinji. Oiri pombi inopinda yepakati frequency quenching kudziyisa zone kuburikidza roller tafura. Iyo yekudziya nzvimbo inoumbwa neseti ye3000kW yepakati frequency magetsi uye seti ye1200kW yepakati frequency magetsi emagetsi ane akawanda seti ekudziya induction coils kuti igadzire inodzima induction yekudziya nzvimbo kuti ive nechokwadi chekushisa chakafanana chebasa rekushanda. Kupisa tembiricha ndeye 850℃～1000℃. Isa inotengeswa kunze-mavara maviri colorimetric infrared thermometer pakubuda kweyekupisa coil kuti utarise kupisa kwekupisa kwetubhing, uye pindura chiratidzo kune yekudzora sisitimu yepakati frequency magetsi ekugadzirisa otomatiki simba rekubuda kweyepakati frequency simba. kugovera kuumba yakavharwa-loop control system kugadzirisa Kupisa kwekupisa kwepombi yesimbi kunodzorwa mukati mekubvumirwa kukanganisa kukanganisa.

Iyo inopisa simbi pombi inopinda munzvimbo yekupfapfaidza quenching. Sezvo iyo workpiece yakagadzirwa nekabhoni-manganese simbi ine kabhoni yemukati inosvika 0.3% kana yepakati uye yakaderera alloyed chromium-molybdenum simbi uye chromium-manganese-molybdenum simbi, mvura yakachena inokodzera kudzima svikiro. Isu tinoshandisa rin’i-yakaita kutonhora mudziyo kuti tirambe tichipfapfaidza yakakwira-kudzvanywa mvura pamusoro pepombi inopisa yesimbi, uye kupfapfaidza iyo yakasimba kwemasekonzi 5-15 kuti iwane shanduko yekudzima martensite. Nechikonzero ichi, takasarudza maviri seti epamusoro-kuyerera uye yakakwirira-kumanikidza mvura pombi (kumanikidza kuri 125 metres paminiti uye kutenderera kwemvura kuri 1000m3/h), uye simba rose riri pamusoro pe500kW, kuitira kuti uwane mhedzisiro yekukurumidza uye yunifomu kutonhora kunodiwa kudzima kwakazara kwepombi madziro. Ita shuwa kuti iyo firimu yemhepo inogadzirwa pamusoro pepombi yesimbi inoparadzwa, kuitira kuti pombi yesimbi inokurumidza kusvika kune martensite shanduko yekushisa, uye iyo yese ichashandurwa kuita quenched martensite, uye hapana troostite inodzimwa ichagadzirwa, nekudaro kuve nechokwadi. tempered sorbite. Sezvo iyo oxide chiyero uye guruva pamusoro pepombi yesimbi ichidonha mupfapfaidzo uye ichipinda mukati mekudzima, svikiro rekudzima rinofanirwa kugadziriswa nekukasharara kwesefa yetangi yekuchera, magineti suction filtration, mesh filtration uye mamwe akawanda- kurapa kwedariro kuita kuti mvura yakasviba ichene uye isavharika. Iyo muromo inogona kushandiswa zvakare.

Iyo nzvimbo yekupfapfaidza yakashongedzerwa nekuzviparadzanisa baffles kudzivirira kupfacha kwemvura, izvo zvinobatsira kudzoreredza mvura uye kuderedza kurasikirwa kwemvura ine turbid. Chivharo chekudzivirira chakaiswawo kudzivirira kupfapfaidza kwemhepo kuti ive nechokwadi chekuoma kwewekishopu.

Iyo pombi yesimbi yakapfapfaidzwa inotakurwa kubva patafura ye roller kuenda kune chikamu chekubvisa mvura mupombi, uye pombi inosimudzwa patafura yakarerekera nemuchina wekuchinja pneumatic. Mushure mekudonha kweanopfuura maminetsi mashanu, inosimudzwa nemuchina wekutenderedza pneumatic kuenda kune tempering line roller tafura. Pasi pedhiraivha yetafura yeroller, inopinda mukati meiyo frequency tempering induction heat zone, uye tembiricha yekudziya yekudziya inowanzo 5 ° C kusvika 600 ° C. Iyo yepakati frequency induction yekudziisa magetsi inzvimbo inodziya induction yekudziya inoumbwa neseti ye750kW uye seti ye1900kW inosanganisira akawanda mapoka emainduction coils. Iyo inotengeswa kunze-mavara maviri colorimetric infrared thermometer inoiswa pakubuda kweyekupedzisira induction coil yekutarisa kupisa kwepombi yemafuta, uye ine basa rekudzoreredza chiratidzo kune yepakati frequency magetsi uye kugadzirisa otomatiki simba rinobuda repakati. frequency simba rekupa kuumba yakavharwa-loop control system. Iyo yakadzikama yesimbi pombi inopfuura nepakati-yakanyanya-kudzvanywa mvura yekudzikisa mudziyo patafura ye roller. Iyo pombi yesimbi inowana kuderera kwekuita pasi pekutsvaira kwepamusoro-kumanikidza jet mvura. Iyo pombi yesimbi mushure mekudonha ichipfuura nepakati pe sensor munzvimbo yekudziya uye inotenderedzwa nepneumatic drive nhanho nhanho. Iyo yekudyisa inosimudza pombi yesimbi zvishoma nezvishoma, inoiisa pamubhedha unotonhorera uye zvishoma nezvishoma inotenderera uye inokunguruka, zvishoma nezvishoma kutonhora. Ipapo mapaipi esimbi anounganidzwa mumabhasikiti pakubuda kwemubhedha wekutonhora, uye obva asungwa nemaoko, akaiswa uye akasimudzwa kune chikamu chinotevera.
