Metal casting Crucible .
Crucible yɛ anwenne a wɔde nwene nneɛma, a mpɛn pii no ɛyɛ dade nneɛma, ansa na wɔatow. Eyi hwehwɛ sɛ wɔde nneɛma a ɛkorɔn yiye-ɔhyew a ɛko tia, ne nnuru ne honam fam ahoɔden a ɛda nsow ka ho. Anyɛ yiye koraa no, ɛsɛ sɛ crucibles no nya melting point a ɛkorɔn sen nneɛma a ɛwɔ mu no.
Metal crucible adeɛ no gyina ne dwumadie field, ɔhyew a ɛkorɔn a ɛko tia, corrosion resistance ne ɛka so mfasoɔ so titire. Nea edidi so yi yɛ nneɛma a wɔtaa de kɔ amannɔne a ɛyɛ dade a wɔde kɔ amannɔne ne ne su ahorow:
1. cast-dadeɛ a ɛwɔ ahina mu .
Su: .
Ɛka a ɛba fam: Dade a wɔde gu mu ne ade titiriw a wɔde yɛ dade a wɔde di dwuma wɔ amanne kwan so, a ɛfata ma nneɛma pii a wɔyɛ, bo a wɔbɔ.
Ɔhyew a ɛkɔ so yiye: Ebetumi de ɔhyew akɔ ntɛmntɛm, a ɛfata ma melting low melting point metals (te sɛ aluminum, zinc).
Nneɛma a wɔde kata so ho banbɔ: Ebetumi ayɛ ade bere a ɛne dade a ayɛ hyew (te sɛ aluminium) no di nkitaho tẽẽ, ne borax, ceramic anaa nkyene a wɔde kata so na ama efĩ amma.
Application scenarios: .
Titiriw no, wɔde di dwuma ma non{0}}iron dade a wɔde gu (te sɛ aluminum, zinc alloy).
Aman a afei na wɔrenya nkɔsoɔ no gua so gua a wɔde kɔ amannɔne no taa ba anaasɛ ɛho ka-mmeae a ɛho hia.

2. Nickel-gyinaso alloy crucible .
Nneɛma a wɔtaa yɛ:
Inconel Series (sɛ nhwɛso no, Inconel 600 / 601): Ɔhyew a ɛko tia (ɛkɔ 1200 C anaa nea ɛboro saa), oxidation a ɛko tia ne nea ɛko tia nsɛe.
Hastelloy series (te sɛ Hastelloy C276): Acid a ɛyɛ den a ɛko tia, alkali a ɛyɛ den a ɛyɛ mmerɛw, a ɛfata sɛ wɔde yɛ dade a ɛyɛ adwuma yiye.
Su: .
Ɔhyew a ɛkorɔn a ɛyɛ adwuma yiye: Ɛfata ma ɔhyew a ɛkorɔn a wɔde yɛ aduru (te sɛ titanium, nickel-gyinaso aduru).
Nnuru a ɛtumi gyina ano: Ɛyɛ den sɛ ɛbɛgyina wɔ acid anaa alkaline tebea mu.
Ɛka a wɔbɔ kɛse: Nneɛma a wɔde yɛ nneɛma ne nneɛma a wɔyɛ no yɛ den, ne bo yɛ den sɛ wɔde bɛkɔ amannɔne.
Application scenarios: .
High-Awiei a wɔyɛ (te sɛ ahunmu, nuklea adwumayɛ).
titiriw na wɔde kɔ Europa, United States, Japan ne South Korea ne aman afoforo a wɔanya nkɔso wɔ mfiridwuma mu.

3. dade a ɛnyɛ den a ɛyɛ ahina (304 / 316 dade a ɛnyɛ den) .
Su: .
corrosion resistance pa: ɛfata ma melting low melting point, non{0}}corrosive metals (te sɛ tin, lead).
Sikasɛm ne mfaso: Ɛka a wɔbɔ no sua sen nickel base alloy no, nanso ɔhyew a ɛkɔ soro no ano brɛ ase (mpɛn pii no ɛnnkɔ soro nsen 1000 C).
Aduru a wɔde yɛ asase ani a ɛho hia: Ɛsɛ sɛ wɔde ade bi a ɛma ɔhyew no ano brɛ ase kɛse kata mfonini ahorow bi so.
Application scenarios: .
Laboratory, adwumayɛbea ketewaa bi.
Nneɛma a wɔde kɔ gua a ɛrenya nkɔso a ɛwɔ corrosion resistance ahwehwɛde a ɛkɔ fam (sɛ nhwɛso no, Asia Kesee Fam Apuei, Amerika Kesee Fam).

4. Molybdenum / Tungsten aduru a wɔde yɛ aduru a wɔfrɛ no crucible .
Su: .
Ultra-High melting point: Molybdenum (2620 C), tungsten (3422 C), betumi adi dwuma wɔ mframa a ɛnyɛ adwuma anaasɛ vacuum tebea mu.
Ɔhyew a ɛkorɔn creep resistance: ɛfata ma melting ultra-a ɛkorɔn ɔhyew dade (te sɛ titanium, tantalum, asase so dade a ɛntaa nsi).
Brittleness: Sɛnea ɛbɛyɛ a wɔbɛkwati mfiridwuma mu nkɛntɛnso, ɛka kɛse a wɔbɔ wɔ nneɛma a wɔyɛ ho.
Application scenarios: .
Semiconductor, dade adwuma titiriw.
Nneɛma a wɔde kɔ amannɔne no sua, nanso ne bo yɛ den, titiriw na ɛsen kɔ aman a wɔanya nkɔso wɔ nyansahu ne mfiridwuma mu (te sɛ United States, Germany, Japan).

5. Titanium aduru a wɔde yɛ ahina .
Su: .
Nneɛma a emu yɛ hare: Ɛba fam, ɛnyɛ den sɛ ɛbɛyɛ adwuma.
Porrosion a ɛyɛ den a ɛko tia: Ɛfata ma melting acid molten nkyene anaa dade a ɛho tew kɛse.
Ɛka kɛse: Titanium dade bo yɛ den na ɛyɛ den sɛ wɔbɛyɛ ho adwuma.
Application scenarios: .
Nneɛma a ɛho tew kɛse a wɔde tew dade ho (te sɛ ɛlɛtrɔnik grade silicon, dade a ɛsom bo).
Fa kɔ soro-awieɛ nneɛma a wɔyɛ no mfuo (te sɛ semiconductor adwumayɛ wɔ South Korea ne Taiwan).
Paw afotu na fa kɔ amannɔne .
Popa Fa Di Dwuma: Paw nneɛma sɛnea dade a wɔabɔ no (melting point, reactivity) te.
Mmara a wɔde di dwuma: Nneɛma a wɔde kɔ amannɔne no bedi ɔman a wɔde wɔn ani asi so no nneɛma a atwa yɛn ho ahyia ne ahobammɔ ho gyinapɛn ahorow ho dwuma (sɛ nhwɛso no, EU ROHS, Reach).
Coating Technology: The high-end market no de n’adwene si ɔhyew a ɛkɔ soro a ɛko tia ne nneɛma a atwa yɛn ho ahyia ho banbɔ so kɛse wɔ ade a wɔde kata so no ho (te sɛ boron-free ceramic coating).
Ahwehwɛdeɛ a ɛfa sɛdeɛ wɔpɛ: Nnwuma titire (te sɛ nuklea adwumayɛ) betumi ahwehwɛ sɛ wɔde nneɛma a wɔde afra a wɔayɛ no sɛdeɛ wɔpɛ anaasɛ composite structure crucibles.
