Zvinoenderana nemaitiro ekuumba:Kanda rolls uye forged rolls.
Castingrollskureva mhando dzemapumburu anogadzirwa nekukandwa kwakananga kwesimbi yakanyungudutswa yakanyungudutswa kana simbi yakanyungudutswa.
Mipumburu yekukanda inogona kupatsanurwa muzvikamu zviviri: mipumburu yesimbi yakakandwa uye simbi yakakandwa maererano nezvinhu;zvinoenderana nemaitiro ekugadzira, anogona kukamurwa kuita mapoka maviri: akabatanidzwa ekukanda rolls uye composite casting rolls.
Forging rolls inokamurwa nezvinhu zvinotevera:
(1) Kugadzira alloy simbi rolls;
(2) Kugadzira semi-simbi rolls;
(3) Kugadzira semi-high-speed simbi rolls;
(4) Mipumburu yesimbi chena yakaumbwa.
Zvinoenderana neiyo process nzira:Integral rolls, metallurgical composite rolls uye yakasanganiswarolls.
1. Inofananidzwa nemupumburu wakaumbwa, iyo yose yakakandwa kana kuumbwa nechinhu chimwe chete chekunze kwekunze, nheyo uye mutsipa wepumburu yose.Iyo yekunze layer yemupumburu muviri uye mutsipa zvine zvimiro zvakasiyana uye zvivakwa kuburikidza nekukanda kana Forging maitiro uye kupisa kurapwa maitiro kudzora uye kugadzirisa.Ose ari maviri efoged rolls uye static cast rolls akakosha rolls.Integral rolls yakakamurwa kuita yakakosha kukanda uye yakakosha forging rolls.
2. Metallurgical composite casting rolls inonyanya kusanganisira semi-flushing composite casting, kufashukira (full flushing) composite casting, uye centrifugal composite casting.Mhando dzemapumburu anoumbwa anogadzirwa nenzira dzakakosha dzakaumbwa senge isostatic pressing (HIP-Hot Isostatically Pressed) uye electroslag welding.Mupumburu wakabatanidzwa unonyanya kuve wakasanganiswa wemapumburu.
Nekugadzira zvinhu:
Kanda simbi yakatevedzana rolls, cast iron series rolls uye forged series rolls
Inowanzo shandiswa mhando dzekupisa kupisa kwema rolls: kusagadzikana kumisa annealing, isothermal spheroidizing annealing, diffusion annealing, normalizing, tempering, quenching, cryogenic treatment.
Zvinoenderana nechimiro chemuviri roll:
Kune nzira dzakasiyana dzekuisa ma rolls.Zvinoenderana nechimiro cheiyo roll body, yakakamurwa kuita cylindrical uye isiri-cylindrical, yekutanga inonyanya kushandiswa kugadzira mahwendefa, mitsetse, profiles uye waya, uye iyo yekupedzisira inonyanya kushandiswa kugadzira mapaipi.
Zvinoenderana nekuti inosangana nechidimbu chakakungurutswa:
Yakakamurwa kuita basa rolls uye backup rolls.Mipumburu inobata zvakananga kune rolling stock inonzi work rolls;iyo mipumburu inoiswa kumashure kana parutivi rwemapumburu ebasa pasina kudhumhana zvakananga neiyo rolling stock kuti iwedzere kuoma uye kusimba kweiyo mipumburu yebasa inonzi backup rolls.
Maererano nekushandisa rack:
Zvinoenderana nekushandiswa kwechigadziko, chakakamurwa kuita maruva anotumbuka, roughing rolls, yepakati rolls uye yekupedzisa rolls.Zvinoenderana nekusiyana kwezvinhu zvekupetera, yakakamurwa kuita strip rolls, rail beam rolls, waya rod rolls uye pombi rolls.Inogona zvakare kukamurwa kuita hot rolls uye inotonhora rolls zvinoenderana nemamiriro eiyo rolling stock panguva yekukunguruka.
Zvinoenderana nekuoma kukosha:
(1) Soft rolls Shore hardness ingangoita 30 ~ 40, inoshandiswa kugadzira michina yekubvisa, rough rolling mill yechikamu chikuru chesimbi zvigayo, nezvimwe.
(2) Semi-hard rolls Shore hardness inenge 40 ~ 60, inoshandiswa kuita rough rolling mill, yepakati uye diki chikamu chesimbi chigayo uye simbi ndiro.
(3) Mipumburu yakaoma-yakaoma Kuoma kweshore kunenge 60 ~ 85, inoshandiswa kune rough rolling mill yeplate yakatetepa, yepakati ndiro, yepakati chikamu chesimbi uye chikamu chiduku chesimbi chigayo uye mabheji emakumbo mana-akakwirira anokunguruka.
(4) Mipumburu yakaoma yakawedzera Hurema hwepashore hunosvika 85 ~ 100, hunoshandiswa mumagayo anotonhora anokunguruka.
Maererano nemhando yechigayo:
(1) Flat roll.NdizvozvoRolling Mill Rolls, the roll body is cylindrical.Kazhinji, mipumburu yesimbi inopisa-yakaputirwa inogadzirwa kuita chimiro checoncave zvishoma, uye kana ichipisa uye ichiwedzerwa, chimiro chiri nani chinogona kuwanikwa;mipumburu yesimbi inotonhora-yakakungurutswa inogadzirwa kuita zvishoma, uye mipumburu inokotama panguva yekukunguruka kuti iwane chimiro chakanaka.
(2) Grooved rolls.Inoshandiswa kukungurutsa zvikamu zvakakura, zvepakati uye zvidiki, tambo dzewaya uye maruva.Magrooves anotemerwa pamusoro pemupumburu kuti agadzire iyo rolling stock.
(3) Mipumburu inokosha.Inoshandiswa mumagayo anokosha ekukungurusa akadai sepombi yesimbizvigayo, zvigayo zvemavhiri, zvigayo zvesimbi zvinotenderedza bhora uye zvigayo zvinobaya.Mipumburu yeguyo iyi ine maumbirwo akasiyana-siyana, akadai semapumburu akakungurutswa nemusimboti we skew rolling musimbi pombi rolling, ayo ari conical, waist drum kana disc.
