Basa rezvinyorwa zvezvigadzirwa muGrey-cast iron

1. Manganese uye Sarufa
Generally speaking, sulfur is a harmful element. But for gray cast iron, a small amount of sulfur plays a very important role in the refinement of graphite core and cocrystal groups. Therefore, the sulfur content in gray cast iron should not be less than 0.06%, and it is best to keep between 0.06% and 0.08%. If the sulfur content is too high (>0.18%), marudzi ese ekukuvadza anozoonekwa uye kukanganisa mhando yekukanda.
Sarufa chinhu chine chimiro chakasimba chemakemikari. Kana iyo Manganese zvirimo mune yakakandwa simbi yakaderera kwazvo, Sulfa uye Simbi inogadzira nzvimbo yeChinyorwa cheCarryStals needareji neCarbon
Fes inogona kunyungudutswa mumhinduro yesimbi. Kana Simbi Simba, Sarufa muAustenite uye Carbonization Solid ishoma, yakazopfumiswa muchimiro chesimbi
Grey akakanda simbi, kushamwaridzana kweSrufu naMamanese kwakanyanya kupfuura zvesimbi, uye kuumbwa kwevanhu vanga vanyaradzaniswa mukuita kwakatsanangurwa mune inotevera equation.
Mn + fes mnn + fe
Iyo yekunyungudutsa nzvimbo yeVMN ndeye 1620 degree. MuGrey Sed Iron, MN MN MNS uye isina kukuvadza bhuruu kusanganisa, iyo inopararira yakapihwa mune yesimbi matrix, uye inobatsira kugadzirisa maitiro ekugadzirisa kwesimbi uye kugadzirisa hupenyu hwechishandiso.
MuGrey Cast Iron, MN uye Fes inogona kupinda interdsolve, saka huwandu hweManganese uye sarufa mune compound sulfide (mnfe) s iri kushanduka. Sarufa uye oksijeni inogona zvakare kuve yakaomarara, saka grey cast cast simbi, makomputa anokonzerwa nekumiririrwa naFexmnysvow, uko kukosha kwe x, y, v uye w kuchashanduka nemamiriro ezvinhu akakandwa.
Mumakore achangopfuura, kudzidza nekuwanda kweMetercgraphic ongororo yakaratidza kuti kune anenge mamirioni makumi mana nemashanu emamirioni ekusanganisa mu1cm3 ashm3 ashmd ndeye 2 ~ 23 Micro. Iyo huwandu hwakazara hweshoma pane isingasviki 0,01% yehuremu hwear nesimbi.
Sulfur iripo muFes kana Ternary Co-Crystal, Icho Chinyorwa cheCrassStive yeChinyorwa cheChinyorwa, uye inowedzera Supercal Sistification, nekudaro inowedzera iyo chena yemuromo yekukanda simbi. Mushure mekusimbisa, iyo fes kana yekoni yekukona pamutambo weboka rekoni rechikanda richaita manhamba ekukanda simbi yakaderera uye iyo brittleness yakakura. Uku ndiko kukuvadza kweSulfu.
Kana mari yakakwana yeManganese inowedzerwa kune yakakwenenzverwa iron kuti inhibit fes kugadzirwa uye inoparadzira kupararira kusimbisa, Sulfa ichava basa rakanaka uye rinobatsira mukubudirira uye kukura kwegrafiti. Mhedzisiro dzinosimbisa Iron Diki Crystal diki, graphite iri mhando A, hakuzove nemuromo machena. Kuita chimiro cheiyo graphite pepa rinogutsa, izvo zvishoma zvemukati zve sarufa mune grey cyren simbi inofanirwa kuve 006%. Iyo sarufa yezvinyorwa yakaderera pane iyi kukosha, uye kugovera kwepafirita graphite mu simbi yakakandwa yakaipa, uye zviri nyore kuburitsa muromo chena.
Basa guru reManganese muGrey rakakanda simbi ndeyekudzora sarufa uye inhibit fes kuumbwa. Nekuti iyo chiyero cheatomu uremu weManganese kuSulfu ndeye 1.71. Iyo mn my yakafanana nerudzi rweManganese uye sarufa yakaumbwa mune yakakandwa simbi ndeye 1.71. Mangn yakakwira kupfuura kuenzana, inonzi
