Melting crucible

Muindasitiri yekunyungudutsa simbi, kunyanya kune ekutanga uye mashandiro ekunyungudutsa, kusarudza crucible chaiyo kwakakosha pakubudirira uye kunaka kwechigadzirwa. Nyanzvi mukugadzira simbi, kunyanya avo vanobatanidzwa mualuminium uye alloys ayo, vanoda akunyunguduka crucible iyo inopa kuvimbika uye kuita. Iyi sumo inoongorora maficha, zvakatemwa, uye zvakanakira zveduCrucible For FoundryuyeCrucible For Metal Melting, kuve nechokwadi chekuti unoita sarudzo ine ruzivo nezvekuita kwako.

Mamiriro Akakosha Yedu Inonyungudika Crucibles

1. Crucible Materials:
   • Silicon Carbide Crucibles: Anozivikanwa nekunaka kwazvo kupisa kwemafuta, aya macrucibles anogona kushanda nemazvo patembiricha kusvika1700°C, inopfuura nekure panonyungudika aruminiyamu (660.37°C). Chimiro chavo chepamusoro-density chinopa simba rinoshamisa uye kuramba deformation.
   • Carbonized Silicon Carbide Crucibles: Shanduro yakavandudzwa inogadzirisa kusasimba kwakajairika kunowanikwa mune zvechinyakare crucibles, senge kuderera kwesimba uye kushomeka kwekushomeka kwemafuta. Aya macrucibles anoshandisa musanganiswa wekabhoni fiber uye silicon carbide, kuve nechokwadi chepamusoro kuita.
2. Best Crucible Material:
   • Yedu silicon carbide crucibles inopa yakasarudzika maitiro, anosanganisira:
     • Melting Point: Kusvika pa2700°C, yakakodzera kushandiswa kwakasiyana-siyana kwepamusoro-tembiricha.
     • Density: 3.21 g/cm³, zvichibatsira pakusimba kwavo kwakasimba.
     • Thermal Conductivity: 120 W/m·K, inogonesa kukurumidza uye yunifomu yekugovera kupisa kwekuvandudza kunyunguduka kushanda.
     • Thermal Kuwedzera Coefficient: 4.0 × 10⁻⁶/°Cmuhuwandu hwe20-1000 ° C, kuderedza kushushikana kwekushisa.
3. Crucible Temperature Range:
   • Macrucibles edu akagadzirirwa kutsungirira tembiricha yekushanda ye800°C kusvika 2000°Cnechinguva chidiki tembiricha kuramba kwe2200°C, kuve nechokwadi chekunyunguduka kwakachengeteka uye kwakanaka kwesimbi dzakasiyana-siyana.

Zvinodiwa (Customizable)

• Ukobvu Kuderedza: Yedu carbonized silicon carbide crucibles yakagadzirwa nekudzikisira ukobvu hwe30%, kuwedzera thermal conductivity uchichengetedza simba.
• Kuwedzera Simba: Simba remacrucibles edu rinowedzerwa ne50%, zvichiita kuti vakwanise kutsungirira kushushikana kwakanyanya kwemagetsi.
• Thermal Shock Resistance: Yakawedzerwa ne40%, kuderedza mukana wekutsemuka panguva yekudziya nekukurumidza uye kutonhora.

Manufacturing Process

Iyo nzira yekugadzira yedu carbonized silicon carbide crucibles inosanganisira akati wandei akakosha matanho:

1. Preform Creation: Carbon fiber inofanogadziriswa kuita fomu yakakodzera kugadzirwa kwecrucible.
2. Carbonization: Iyi nhanho inogadza yekutanga silicon carbide chimiro.
3. Densification uye Kucheneswa: Kuwedzera carbonization kunowedzera density yezvinhu uye kugadzikana kwemakemikari.
4. Silicone: Iyo crucible yakanyikwa musilicon yakanyungudutswa kuti iwedzere simba rayo uye kusaita ngura.
5. Final Shaping: Iyo crucible yakaumbwa kuti isangane nezvinodiwa chaizvo, kuve nechokwadi chekuita kwakakwana.

Zvakanakira uye Kuita

• High-Tembiricha Simba: Nekukwanisa kuchengetedza kutendeseka kwechimiro pakupisa kwakanyanya, yedu silicon carbide crucibles inovimbisa kuvimbika panguva yekunyungudika kwepamusoro-tembiricha maitiro.
• Corrosion Resistance: Aya macrucibles anoramba kukoromoka kubva kunyungudutswa aluminiyamu uye mamwe masimbi, achiwedzera zvakanyanya hupenyu hwawo uye kuderedza kutsiva frequency.
• Kemikari Inert: Silicon carbide haina kuita nealuminium, inovimbisa kuchena kwesimbi yakanyungudutswa uye kudzivirira kusvibiswa kubva kune tsvina.
• Mechanical Simba: Nekukotama simba re400-600 MPa, crucibles yedu inogona kumira mitoro inorema, ichiita kuti ive yakakodzera kune inoda kunyorera.

Applications

Silicon carbide meting crucibles anoshandiswa zvakanyanya mu:

• Aluminium Smelting Plants: Yakakosha pakunyungudutsa uye kuchenesa aluminium ingots, kuve nechokwadi chemhando yepamusoro zvigadzirwa zvealuminium.
• Aluminium Alloy Foundries: Kupa nzvimbo dzakagadzikana dzepamusoro-tembiricha yekukandira zvikamu zvealuminium alloy, kuvandudza kunaka kwechigadzirwa uye kuderedza zvimedu zvimedu.30%.
• Marabhoritari uye Masangano ekutsvagisa: Yakanakira kuedza kwepamusoro-tembiricha, kuve nechokwadi che data rakarurama uye mhedzisiro yakavimbika nekuda kwekemikari inertness uye kugadzikana kwekupisa.

Mhedziso

Yeducrucibles inonyungudukamaturusi akakosha muindasitiri yekunyungudika uye simbi inonyungudika, inozivikanwa nekuita kwayo kwakasiyana uye kuita kwakasiyana-siyana. Nekuisa pamberi pemhando yepamusoro uye inoenderera mberi hunyanzvi, takazvipira kupa vatengi vedu mhinduro dzemhando yepamusoro dzekunyungudika dzakagadzirirwa kune zvavanoda chaizvo. Kana iwe uri kutsvaga yakavimbika crucible yeako simbi kunyunguduka mashandiro, usatarise kumberi kune yedu silicon carbide crucibles yakagadzirwa nehunyanzvi uye hunyanzvi. Kuti uwane kubvunza kana rumwe ruzivo, ndapota inzwa wakasununguka kutibata nesu.
