Mutuwar ita ce ainihin abin da ke cikin injin pellet. Kuma shine mabuɗinyin pellets abinci. Dangane da kididdigar da ba ta cika ba, farashin injin pellet ya mutu asara sama da kashi 25% na farashin kula da duk taron samar da kayayyaki. Ga kowane kashi kashi ya karu a kudade, gasa kasuwancin ku ya ragu da 0.25%. Don haka ƙayyadaddun injin pellet yana da mahimmanci.
Shanghai Zhengyi (CPSHZY) kwararre neciyar da pellet niƙamai kaya a china. Muna samar da ingantacciyar niƙa mai ɗorewa, injina mai fa'ida da kumasassan niƙa pellet, kamar lebur mutuwa, zobe mutu, pellet niƙa abin nadi, da sauran sassa na pellet inji.
1.Pellet niƙa mutu abu
Mutuwar pellet ɗin gabaɗaya ana yin ta ne da ƙarfe na carbon, gami da tsarin ƙarfe ko bakin karfe ta hanyar ƙirƙira, injina, hakowa, da hanyoyin magance zafi. Mai amfani zai iya zaɓar bisa ga lalatawar albarkatun ɗanyen abu. Abu na pellet niƙa mutu ya kamata a yi na gami tsarin karfe ko bakin karfe zobe mold.
Carbon tsarin karfe, kamar 45 karfe, zafi magani taurin ne kullum 45-50 HRC, shi ne a low-sa zobe mutu abu, da lalacewa juriya da lalata juriya ba su da kyau, yanzu m shafe.
Alloy tsarin karfe, kamar 40Cr, 35CrMo, da dai sauransu, tare da zafi magani taurin sama 50HRC da kyau hadedde inji Properties. Mutuwar da aka yi da wannan abu yana da ƙarfi mai ƙarfi da juriya, amma rashin lahani shine juriyar lalata ba ta da kyau, musamman don ciyar da kifi.
Farashin zobe ya mutu, wanda aka yi da kayan, marigold pellets, guntun katako, bambaro, da dai sauransu, ya fi girma fiye da bakin karfe. Dukansu 20CrMnTi da 20MnCr5 ƙananan karafa ne masu ƙyalli, dukansu iri ɗaya ne, sai dai na farko karfen China ne, na Jamus kuma na Jamus. Tun da Ti, wani sinadari, ba kasafai ake samunsa a kasashen waje ba, ana amfani da 20CrMnTi ko 20CrMn daga kasar Sin maimakon 20MnCr5 daga Jamus, don haka baya fada cikin iyakokin tsarin karfe. Duk da haka, ƙaƙƙarfan ƙaƙƙarfan wannan ƙarfe yana iyakance ta hanyar aikin carburizing zuwa zurfin zurfin 1.2 mm, wanda kuma shine amfani da ƙananan farashin wannan karfe.
Bakin karfe kayan sun hada da Jamus bakin karfe X46Cr13, China bakin karfe 4Cr13, da dai sauransu Wadannan kayan da mafi kyau stiffness da taurin, mafi girma zafi magani taurin fiye da carburized karfe, taurare yadudduka fiye da carburized karfe, da kyau lalacewa da lalata juriya, sakamakon da tsawon rai ta halitta mafi girma farashin fiye da carburized karafa. Saboda tsawon rayuwar bakin karfe mutu karfe, mitar sauyawa yana da ƙasa kuma don haka farashin kowace tonne yayi ƙasa.
Gabaɗaya, abin mutuƙar na injunan mutuwa pellet shine kayan haɗin gwal da bakin karfe.
2.Ragon matsawa na pellet niƙa mutu
i=d/l
T=L+M
M shine zurfin ramin da aka rage
Matsakaicin matsawa (i) shine rabon diamita na rami rami (d) da tsayi mai inganci (L) na mutu.
Dangane da yanayin albarkatun ƙasa, rabon shine 8-15, mai amfani yana zaɓar ƙimar matsawa na mutu, kuma yana daidaita ƙayyadaddun ƙayyadaddun matsawa, kamar zaɓin ƙarancin matsawa kaɗan, wanda ke da fa'ida don haɓaka fitarwa, rage yawan fitarwa. amfani da makamashi, rage lalacewa na zobe mold, amma kuma rage ingancin barbashi, kamar pellets ba su da ƙarfi, kama da sako-sako da kuma tsawon ya bambanta, kuma foda ya yi yawa.
3.Yawan buɗewar zobe mutu
Matsakaicin buɗaɗɗen injin pellet mutu shine rabon jimillar yanki na ramin mutu zuwa ingantaccen yanki na mutu. Gabaɗaya, mafi girman ƙimar buɗewar mutuwa, mafi girman yawan adadin barbashi. A ƙarƙashin yanayin tabbatar da ƙarfin mutuwa, za'a iya inganta ƙimar buɗewar zobe ta mutu gwargwadon iko.
Ga wasu albarkatun kasa, a ƙarƙashin yanayin matsi mai ma'ana, bangon injin pellet mutu yana da bakin ciki sosai, don haka ƙarfin mutuwa bai isa ba, kuma abin fashewar mutuwa zai bayyana a cikin samarwa. A wannan lokacin, ya kamata a ƙara yawan kauri na zobe a ƙarƙashin yanayin tabbatar da tsawon tsayin ramin mutu.
4.Daidaita tsakanin injin pellet mutu da abin nadi
Ita ce mafi mahimmancin fasaha don inganta ingantaccen granulation da kuma tsawaita rayuwar mutu. Ya kamata ya ƙunshi abubuwa 4:
- Sabon zobe ya mutu tare da sabon abin nadi, guje wa wuce gona da iri na abin nadi.
- Dangane da yanayin kayan, halaye na nau'in kayan mashin na zabin nau'ikan nau'ikan nau'ikan matsin lamba daban daban, don cimma ingantacciyar hanyar haɓaka tsakanin mutu da yi.
- Makullin don dacewa da rata shine kwanciyar hankali kuma ka'idar ita ce: ba tare da rinjayar iya aiki ba, yi ƙoƙarin shakatawa.
- Sarrafa saurin ciyarwa, daidaita tsayi da gajeren matsayi na ciyar da scraper don sarrafa matsayin ciyarwa, rarraba kayan abu.
5.Pellet niƙa mutu sarrafa tsari
Ring die ramukan suna da matuƙar buƙata ta fuskar sarrafawa da sarrafa kayan aiki, kuma ga bakin karfe, ana buƙatar ƙwanƙwasa bindigu na musamman da na'urorin kula da zafi don samar da ingantacciyar zobe na mutu. Kyakkyawan tsari na kashe zafin jiki na zafin jiki na iya inganta ƙarfin ƙarfi, taurin, juriya, ƙarfin gajiya da taurin ƙarfe. Koyaya, ikon tabbatar da daidaiton taurin wuya ga kowane rami mai mutuwa yana buƙatar babban matakin ƙwarewar sarrafawa da gogewa mai tsayi.
6.Mutuwar saman bangon ciki na ramin mutu
Har ila yau, ƙaƙƙarfan saman ƙasa alama ce mai mahimmanci na ingancin mutuwar zobe. Gabaɗaya, ƙananan ƙimar bangon bangon ciki na ciki zai inganta ingancin dacewa, rage lalacewa da tsawaita rayuwar zobe ya mutu, amma farashin sarrafa zoben ya mutu zai karu.
Ring rami roughness kuma rinjayar da matsawa rabo da kafa na barbashi, kazalika da samar yadda ya dace. A daidai wannan zobe mutu matsawa rabo, da ƙananan roughness darajar, da ƙananan extrusion juriya na itacen guntu ko abinci, da smoother fitarwa, da mafi girma ingancin pellets samar da mafi girma da samar da yadda ya dace. Kyakkyawan sarrafa ramin zobe na iya zama har zuwa 0.8-1.6 microns, ƙarancin zobe yana kusan 0.8 microns, injin daidai akan kayan da ake zubarwa, babu niƙa.
