Chii chinonzi Ferro Alloys?

Alloy musanganiswa kana kuti solid solution ine simbi. Saizvozvo, ferroalloy musanganiswa wealuminium yakasanganiswa nezvimwe zvinhu zvakaita semanganese, aruminiyamu kana silicon muhupamhi hwepamusoro. Alloying inovandudza zvimiro zvemuviri zvechinhu, senge density, reactivity, Young's modulus, magetsi conductivity uye thermal conductivity. Naizvozvo, maferroalloys anoratidza zvivakwa zvakasiyana nekuti masanganiswa esimbi akasiyana muzvikamu zvakasiyana anoratidza huwandu hwakawanda hwezvivakwa. Uye zvakare, alloying inoshandurawo ma mechanic zvimiro zvezvinhu zvevabereki, kugadzira kuomarara, kuoma, ductility, nezvimwe.
Ferroalloy Products
Mishonga mikuru ye ferroalloys ndeye ferroaluminium, ferrosilicon, ferronickel, ferromolybdenum, ferrotungsten, ferrovanadium, ferromanganese, etc. Kugadzirwa kweimwe ferroalloy kunosanganisira maitiro akawanda anofanira kuteverwa kuti awane zvinodiwa zvemuviri uye zvemagetsi. Kusiyanisa kudiki kwekushisa, kupisa kana kuumbwa kunogona kuburitsa alloys ane akasiyana zvachose zvinhu. Iko kushandiswa kukuru kwemaferroalloys kuvaka kwevagari, kushongedza, mota, indasitiri yesimbi uye zvemagetsi. Indasitiri yesimbi ndiyo mutengi mukuru we ferroalloys nekuti ma ferroalloys anopa zvivakwa zvakasiyana kune simbi alloys uye Stainless simbi.

Ferromolybdenum
Ferromolybdenum inowanzoshandiswa mukugadzirwa kwesimbi yealloy kuvandudza kuoma, kuoma uye kupfeka kuramba kwesimbi. Iyo molybdenum iri muferromolybdenum kazhinji iri pakati pe50% ne90%, uye kushandiswa kwakasiyana kunoda zviri mukati meferromolybdenum.

Ferrosilicon
Ferrosilicon kazhinji ine 15% kusvika 90% silicon, ine yakakwira silicon yemukati. Ferrosilicon chinhu chakakosha alloy, uye kushandiswa kwayo kukuru kugadzirwa kwesimbi. Ferroalloys inobatsira deoxidize simbi uye ferrous simbi. Mukuwedzera, inovandudzawo kuoma, simba uye kudzivisa kuora. China ndiyo inonyanya kugadzira ferrosilicon.

Ferrovanadium
Ferrovanadium inowanzo shandiswa kugadzira alloy simbi yekuvandudza kusimba, kuoma uye kupfeka kuramba kwesimbi. Vanadium yemukati muferrovanadium kazhinji iri pakati pe30% ne80%, uye kushandiswa kwakasiyana kunoda zvirimo zvakasiyana zveferrovanadium.

Ferrochrome
Ferrochrome, inozivikanwawo se chromium iron, inowanzo umbwa ne50% kusvika 70% chromium nehuremu. Chaizvoizvo, ialloy yechromium nesimbi. Ferrochrome inonyanya kushandiswa kugadzira simbi, inoverengera inosvika 80% yekudyiwa kwenyika.

Kazhinji kutaura, ferrochrome inogadzirwa mumagetsi arc furnaces. Maitiro ekugadzira ndeye carbothermic reaction, inoitika pakupisa kwakanyanya kunosvika 2800 ° C. Nhamba huru yemagetsi inodiwa kuti isvike idzi tembiricha dzakakwirira. Naizvozvo, zvinodhura zvakanyanya kugadzira munyika dzine mutengo wemagetsi wakakwira. Vagadziri vakuru ve ferrochrome iChina, South Africa neKazakhstan.

Ferrotungsten
Ferrotungsten inowanzoshandiswa mukugadzira alloy simbi kuwedzera kuoma, kupfeka kuramba uye kupisa kwakanyanya kwesimbi. Iyo tungsten zvirimo muferrotungsten kazhinji iri pakati pe60% ne98%, uye akasiyana maapplication anoda zvakasiyana zvemukati zveferrotungsten.
Kugadzirwa kweferrotungsten kunonyanya kuitiswa nekuputika kwechoto ironmaking kana yemagetsi choto nzira. Mukugadzira simbi muchoto, tungsten-ine ore inoiswa muchoto chinoputika pamwe chete necoke neraimestone yekunyungudutsa kuti ibudise ferroalloys ine tungsten. Muchoto chemagetsi nzira, simbi yearc yemagetsi inoshandiswa kupisa uye kunyungudutsa zvinhu zvakasvibirira zvine tungsten kugadzirira ferrotungsten.

Ferrotitanium
Iyo titanium yemukati muferrotungsten kazhinji iri pakati pe10% ne45%. Kugadzirwa kweferrotungsten kunonyanya kuitiswa nekuputika kwechoto ironmaking kana yemagetsi choto nzira. China ndeimwe yevagadziri vakuru ve ferrotungsten munyika.

Kushandiswa kweferroalloys

Alloy simbi kugadzirwa
Ferroalloys chimwe chezvinhu zvakakosha zvekugadzira simbi yealloy. Nekuwedzera mhando dzakasiyana dzeferroalloys (senge ferrochrome, ferromanganese, ferromolybdenum, ferrosilicon, nezvimwewo) kusimbi, zvimiro zvesimbi zvinogona kuvandudzwa, sekuvandudza kuoma, kusimba, kusapfeka, kusakara, nezvimwewo, kugadzira simbi yakawanda. yakakodzera kune dzakasiyana mainjiniya nekugadzira minda.
Kugadzirwa kwesimbi
Cast iron chinhu chakajairika chekukanda, uye ferroalloys inoita basa rakakosha mukugadzirwa kwesimbi. Kuwedzera chimwe chikamu cheferroalloys kunogona kuvandudza zvivakwa zvemuchina, kupfeka kuramba uye kusakara kwesimbi yakakandwa, zvichiita kuti ive yakakodzera kugadzirwa kwemakina zvikamu, zvikamu zvemotokari, mapaipi, nezvimwe.

Indasitiri yemagetsi
Ferroalloys anoshandiswawo muindasitiri yemagetsi, senge zvinhu zvepakati zvemagetsi emagetsi. Alloy iron ine yakanaka magineti permeability uye yakaderera hysteresis, iyo inogona kunyatso kudzikisa kurasikirwa kwesimba kwemagetsi emagetsi.

Munda wemuchadenga
Kushandiswa kweferroalloys mumunda wemuchadenga kwakakoshawo, sekugadzira zvikamu zvezvimiro uye zvikamu zveinjini zvendege nemaroketi, izvo zvinoda kuti zvikamu izvi zvive nehunhu hwakadai sehuremu, simba repamusoro uye kupisa kwakanyanya.

Chemical Industry
Muindasitiri yemakemikari, ferroalloys anowanzo shandiswa seanotakura anotakura mune organic synthesis reaction, gasi kucheneswa uye mamwe maitiro.

Refractory zvinhu
Mamwe ma ferroalloys anogona zvakare kushandiswa mukugadzirira kwezvinhu zvinoramba kuvandudza tembiricha yekudzivirira yezvigadzirwa. Ivo vanowanzo shandiswa mukugadzira zvinhu zvinoramba muindasitiri senge ironmaking uye simbi.
