Bincike A Kan Sabon Ƙirƙira Babbar Gudun Karfe Roll Material Quenching Process

Manyan manya-manyan sikelin birgima masu birgima na zamani sun gane mirgina marasa kai da mara iyaka. Abubuwan da ake buƙata don ingancin madaukai, kamar shimfidar shimfidar wuri da bambancin kauri na tsinken da aka yi birgima, suna ƙaruwa da haɓaka, kuma buƙatun ingancin buƙatun aikin suna ƙaruwa. Mafi girman farashin, mafi girman buƙatun akan taurin ƙasa da zurfin Layer mai tauri. Bincike kan kayan aikin mirgina aikin sanyi ya kasance koyaushe yana da ƙima ta masana'antar yi. Daga ƙarfe na farko, a hankali ya haɓaka zuwa 2%Cr, 3%Cr, da 5%Cr karfe.

Ci gabanta yawanci yana dogara ne akan ci gaba da haɓaka abun cikin chromium. A cikin 'yan shekarun nan, kayan aikin ƙarfe mai saurin gudu da na sauri sun bayyana, kuma an sami wasu rahotanni kan nazarin tsarin su da carbides. Masu fasaha na Tianjin Heavy Equipment Engineering Research Co., Ltd. sun yi nazarin tsarin kashe wuta na wani sabon ci gaba da aka ƙera na ƙarfe mai sauri na birgima na aikin yi, kuma ya yi nazarin tasirin zafin zafin akan tsarin, girman hatsi, riƙe austenite da taurin ƙwanƙwasa ƙwanƙwasa. Tasirin, yana ba da ka'idar ka'ida da gwaji don haɓaka babban aikin murɗaɗɗen aikin sanyi.

An ƙirƙira sabon kayan aikin ƙarfe na ƙarfe mai ƙarfi da aka yi amfani da shi a cikin gwajin a cikin murhun shigar da injin 50kg, sannan kuma an ƙirƙira shi a cikin babban zafin jiki a cikin 100mm × 100mm × 250mm, wanda aka sanya shi a 700 ° C na 4h don samun kayan asali don gwajin. Samfurin ƙirar ƙirar ƙarfe shine murabba'in 15mm × 15mm × 15mm, wanda aka ƙone ta hanyar tanda mai nau'in akwati a yanayin zafi daban-daban kuma ta kashe ta sanyaya iska. 660RLD/T Rockwell hardness tester an yi amfani da shi don gano taurin, X'perPro X-ray diffractometer an yi amfani da shi don gano jigon austenite, Axiovert200MAT microscope na gani don gano tsari da girman hatsi, kuma an yi amfani da QUANTA400 microscope na lantarki don lura da carbides.

Tsarin da aka ƙera na sabon ƙirar ƙirar ƙarfe mai ƙarfi mai ƙarfi shine ƙananan bainite + ledeburite + ƙaramin adadin martensite + carbides mai siffa-bar + granular carbides, wanda manyan carbides masu kama da mashaya ke hanzarta yayin ƙarfafawa. Carbides na farko, carbides granular sune carbides na sakandare wanda ya fito daga austenite yayin aikin sanyaya, kuma abun cikin carbide shine 3.6%. bincike ya nuna:

1. Zazzabi mai kashewa yana shafar rushewar carbides. Yayin da zafin zafin yake ƙaruwa, abun da ke cikin carbide a cikin tsarin da aka kashe na babban birki mai sauri yana raguwa a hankali. Lokacin da zazzabi ya hau zuwa 1200 ℃, carbide granular ya narkar da asali
2. Magani, ƙaramin adadin carbide mai yawa ya rage.
3. Yayin da zafin zafin yake ƙaruwa, hatsin ƙarfe mai saurin gudu na ci gaba da ƙaruwa. Lokacin da zafin zafin ya wuce 1040 ° C, yanayin ci gaban hatsi a bayyane yake, rage zafin zafin ya wuce 1160 ° C, girman hatsi ya kai 4.5, kuma tsinken hatsin yana da tsananin gaske.
4. Yayin da zafin zafin ke ƙaruwa, abubuwan da ke riƙe austenite na ci gaba da ƙaruwa. Lokacin da zafin zafin yake ƙasa da 1080 ° C, abun cikin da aka riƙe austenite yana ƙaruwa da sannu a hankali, sannan abun cikinsa yana ƙaruwa sosai. Lokacin da zafin zafin ya kai 1160 ℃, abin da aka riƙe austenite yana ƙaruwa zuwa 38%. Sabili da haka, daga mahangar sarrafa abubuwan da aka riƙe austenite, zafin zafin ya kamata ya kasance ƙasa da 1080 ℃.
5. Lokacin quenching a 1040 ℃, taurin ya kai ƙima mafi girma, har zuwa 64.1HRC. A wannan lokacin, tsarin jujjuyawar ƙarfe mai sauri, girman hatsi, da abun cikin austenite da aka riƙe ya ​​dace da mafi kyau.
6. Ya kamata a zaɓi zafin zazzabi na sabon ƙirƙira babban kayan jujjuyawar ƙarfe tsakanin 1020 ～ 1080 ℃.
