Corundum Mullite Castable Description
Corundum mullite refractory castable minangka bahan refractory unshaped kekuatan dhuwur kanggo didol ing RS Company, sing bisa digunakake ing kiln semen. Corundum mullite castables bisa nindakake sifat dhuwur kayata kekuatan crushing dhuwur, stabilitas suhu dhuwur, resistance kejut termal, nyandhang lan resistance erosi kimia ing lapisan saka boiler stasiun daya gedhe lan peralatan suhu dhuwur liyane. corundum mullite castable refractory bisa digunakake ing tungku baja, kiln semen, tungku kaca, tungku nggawe wesi, kiln terowongan keramik lan ing.
Properties Corundum Mullite Castable
- kekuatan dhuwur,
- resistance nyandhang kuwat,
- Tahan erosi sing apik,
- Stabilitas kejut termal sing apik,
- Resistance suhu dhuwur.
Proses Manufaktur Corundum Mullite Castable
Bahan baku utama corundum mullite castable yaiku agregat aluminium oksida sing entheng, bijih mullite alami murni sing berkualitas tinggi, lan semen kalsium aluminat minangka agen pengikat. corundum mullite refractory castable digawe liwat kobong suhu dhuwur dening pawon industri majeng. kekuatan lentur corundum mullite lan kekuatan compressive mundhak pisanan lan ngurangi banjur karo Tambah saka suhu perawatan panas. Lan nalika isi daya mikro alumina 5%, kekuatan lentur tekan ndhuwur.
Komposisi Corundum Mullite Castable
Isi Al2O3 luwih saka 90%, lan corundum mullite jampel castable karo corundum minangka phase kristal utama sing pipis dispersants cocok, coagulants, serat stainless steel, kang compounded miturut rumus ketat. Corundum mullite castable refractory nduweni akeh ciri, kayata kekuatan suhu dhuwur, nyandhang-resisting lan anti-scour, konduksi panas dhuwur, resistance kejut panas, resistance karat, sealing apik lan kondensasi awal.

- Aplikasi Corundum Mullite Castable
- Corundum mullite refractory castable nduweni fitur saka expansion seragam, resistance kejut termal banget, stabilitas volume suhu dhuwur, kekuatan suhu dhuwur, refractoriness dhuwur ing mbukak, tingkat creep suhu dhuwur kurang, kekuatan crushing dhuwur, tingkat pangowahan dimensi linear kurang, atose dhuwur, apik. resistance kanggo karat kimia, spalling lan nyandhang resistance. Amarga karakter kuwi, lan corundum mullite jampel castable awet dienggo lan kang digunakake Applied ing kiln industri beda, pawon suhu dhuwur lan bagean tombol liyane saka suhu dhuwur, kayata:
- Boiler, blast furnace, kompor blast panas, tungku pemanas,
- Kiln terowongan keramik, kiln semen, pembakar batu bara,
- Pintu tungku, bukaan pakan, tungku baja, tungku gawe wesi,
