2. Kutenderera kunopisa:

Makoiri ekunhonga makoiri. Mapureti esimbi anomonereka Mapureti esimbi emotokari Marata esimbi emotokari Marata esimbi ebhiriji Mapureti esimbi ebhiriji Boiler simbi ndiro Mapureti esimbi Mapuleti asingadziviriri Tsiva kutonhora nekupisa Simbi yakafara uye inorema isingadziviriri moto.

3. Kukunguruka kuchitonhora:

Makoiri akakungurutswa Mapepa akakungurutswa Mashizha emagetsi GB tin-plated WISCO silicon simbi kushandiswa.

4. Ndiro yesimbi inofashaidza uye ndiro yakauraya simbi:

1. Kufashaidza ndiro ndiro yesimbi inopisa-yakakungurutswa kubva kune yakajairwa kabhoni structural simbi inofashaira.Simbi inovira imhando yesimbi ine deoxidation isina kukwana.Chete chiyero chakati che deoxidizer chisina kusimba chinoshandiswa kuita deoxidize simbi yakanyungudutswa.Okisijeni yesimbi yesimbi yakanyungudutswa yakati wandei.Kana simbi yakanyungudutswa ikaiswa muingot mold, kabhoni neokisijeni zvinobata kuburitsa gasi rakawanda, zvichiita kuti simbi yakanyungudutswa ifashaire., Simbi inovira yakawana zita rayo kubva pane izvi.Simbi ine rimmed ine yakaderera kabhoni, uye nekuti haishandise ferrosilicon ye deoxidation, iyo silicon iri musimbi zvakare yakaderera (Si <0.07%).Iyo yekunze simbi inofashaira yakanyungudutswa pasi pemamiriro echisimba kuputika kwesimbi yakanyungudutswa kunokonzerwa nekuvira, saka iyo yekumusoro layer yakachena uye yakaoma, ine yakanaka yemhando yepamusoro, yakanaka plasticity uye stamping zvivakwa, hapana yakakura yakanyungudutswa maburi, uye kucheka musoro. Chiyero chekugadzirwa kwerimmed steel chiri nyore, kushandiswa kweferroalloy kuduku, uye mari yesimbi yakaderera.Mahwendefa esimbi anofashaidzwa anoshandiswa zvakanyanya mukugadzira zvikamu zvakasiyana-siyana zvekutsikisa, kuvaka uye zvivakwa zveinjiniya uye zvimwe zvisinganyanyi kukosha zvemuchina zvikamu.Zvisinei, kune tsvina yakawanda mukati mesimbi inopisa, kupatsanurwa kwakakomba, chimiro chacho hachina kuoma, uye michina yemagetsi haina kuenzana.Panguva imwecheteyo, nekuda kwekuwanda kwegasi musimbi, kuoma kwacho kwakadzikira, kutonhora kwebrittleness uye kuchembera kunzwisiswa kwakakura, uye kuita kwewelding zvakare kwakashata.Naizvozvo, kufashaidza simbi mahwendefa haana kukodzera kugadzira welded zvimiro uye zvimwe zvakakosha zvimiro zvinotakura zvinokonzeresa mitoro uye zvinoshanda pasi pemamiriro ekushisa.

2. Yakaurawa simbi ndiro ndiro yesimbi yakagadzirwa nekabhoni structural simbi yakaurawa nesimbi inopisa.Simbi yakaurayiwa isimbi yakasvibiswa zvachose.Simbi yakanyungudutswa yakanyatso deoxidized neferromanganese, ferrosilicon nealuminium isati yadirwa.Iyo okisijeni yemukati yesimbi yakanyungudutswa yakaderera (kazhinji 0.002-0.003%), uye simbi yakanyungudutswa yakadzikama muingot mold.Iko hakuna chinofashaira chiitiko, saka zita resimbi yakaurayiwa.Pasi pemamiriro ekushanda akajairika, hapana mabhubhu musimbi yakaurayiwa, uye chimiro chakafanana uye chakabatana;nekuda kwekuderera kweokisijeni, simbi ine zvishoma oxide inclusions, yakakwirira kuchena, yakaderera kutonhora brittleness uye kuchembera hunhu;panguva imwecheteyo, kupatsanurwa kwesimbi yakaurayiwa iduku, Kushanda kwacho kwakafanana uye unhu hwakakwirira.Izvo zvisingabatsiri zvesimbi yakaurayiwa ndeye concentrated shrinkage, goho rakaderera uye mutengo wakakwirira.Naizvozvo, simbi yakauraiwa inonyanya kushandiswa kune zvikamu zvinomira pamhepo yakadzika tembiricha, yakashongedzwa zvimiro, uye zvimwe zvinhu zvinoda simba rakawanda.

Low-alloy simbi mahwendefa zvose akaurayiwa uye semi-akaurayiwa simbi mahwendefa.Nekuda kwesimba rayo repamusoro uye kushanda kwepamusoro, inogona kuchengetedza simbi yakawanda uye kuderedza uremu hwechimiro, kushandiswa kwayo kwakawedzera uye kwakawedzera.

5. Yepamusoro-mhando kabhoni structural simbi ndiro:

Yepamusoro-soro kabhoni structural simbi isimbi kabhoni ine kabhoni inodzika isingasviki 0.8%.Simbi iyi ine sarufa shoma, phosphorus uye isiri-metallic inclusions pane kabhoni structural simbi, uye ine zviri nani michina zvinhu.

Yepamusoro-mhando kabhoni structural simbi inogona kupatsanurwa muzvikamu zvitatu zvinoenderana neakasiyana kabhoni simbi: yakaderera-kabhoni simbi (C≤0.25%), yepakati-kabhoni simbi (C iri 0.25-0.6%) uye yakakwirira-kabhoni simbi (C> 0.6) %).

Zvinoenderana neakasiyana manganese emukati, yepamusoro-yemhando kabhoni yekugadzira simbi inogona kukamurwa kuita mapoka maviri: yakajairika manganese yemukati (manganese yemukati 0.25% -0.8%) uye yepamusoro manganese yemukati (manganese yemukati 0.70% -1.20%).Iyo yekupedzisira ine makanika ari nani.Kuita uye kugadzirisa kushanda.

1. High-quality carbon structural simbi inopisa-yakakungurutswa pepa uye simbi strip Yakakwirira-mhando kabhoni structural simbi inopisa-yakakungurutswa yakatetepa simbi pepa uye simbi strip inoshandiswa mumotokari, indasitiri yendege uye mamwe masekete.Simbi dzayo mamakisi ari marimed simbi: 08F, 10F, 15F;akaurawa simbi: 08, 08AL, 10, 15, 20, 25, 30, 35, 40, 45, 50. Low carbon simbi ndiro pazasi 25 uye 25, 30 uye Pamusoro 30 ari medium carbon simbi ndiro.

2. Yepamusoro-mhando kabhoni structural simbi inopisa-yakakungurutswa gobvu simbi mahwendefa uye yakafara simbi mitsetse Yepamusoro-mhando kabhoni structural simbi inopisa-yakakungurutswa gobvu simbi mahwendefa uye yakafara mitsetse yesimbi inoshandiswa muzvikamu zvakasiyana-siyana zvemagadzirirwo.Simbi dzayo mamakisi akadzikira kabhoni simbi dzinosanganisira: 05F, 08F, 08, 10F, 10, 15F, 15, 20F, 20, 25, 20Mn, 25Mn, nezvimwewo;masimbi epakati kabhoni anosanganisira: 30, 35, 40, 45, 50, 55, 60, 30Mn, 40Mn, 50Mn, 60Mn, nezvimwewo;yakakwira kabhoni simbi inosanganisira: 65, 70, 65Mn, nezvimwe.
