Pengecoran investasi (pengecoran lilin sing ilang) minangka cara proses pengecoran kanthi presisi sing bisa ngasilake rincian wangun cedhak-jaring kanthi nggunakake replikasi pola lilin. Casting investasi utawa lilin ilang minangka proses mbentuk logam sing biasane nggunakake pola lilin sing dikubengi cangkang keramik kanggo nggawe cetakan keramik. Nalika cangkang garing, lilin dilebur, mung ninggalake jamur. Banjur komponèn casting kawangun dening pouring logam molten menyang jamur Keramik.
Miturut binders beda kanggo bangunan Nihan, casting investasi bisa dipérang dadi silika sol Binder investasi casting, banyu kaca Binder investasi casting lan casting investasi karo campuran minangka bahan Binder.
Kaca banyu, uga dikenal minangka Sodium Silikat, minangka jinis silikat logam alkali sing larut, sing dadi kaca ing negara padhet lan dadi solusi kaca banyu nalika larut ing banyu. Miturut prabédan saka logam alkali sing ana, ana rong jinis kaca banyu kalium lan kaca banyu soda. Sing terakhir gampang larut ing banyu, ngemot kurang impurities, lan nduweni kinerja sing stabil. Mulane, kaca banyu kanggo casting investasi iku kaca banyu sodium, yaiku Na20·mSiO2, A transparent utawa translucent colloidal solusi banyu kawangun sawise hidrolisis. Komponen kimia utama kaca banyu yaiku silikon oksida lan natrium oksida. Kajaba iku, uga ngandhut jumlah cilik saka impurities. Kaca banyu dudu senyawa tunggal, nanging campuran saka pirang-pirang senyawa.
Ing proses casting investasi, Binder kaca banyu lan nutupi duwe kinerja stabil, rega murah, siklus Nihan-nggawe cendhak lan aplikasi trep. Proses nggawe cangkang kaca banyu cocok kanggo produksi casting investasi kayata baja karbon, baja paduan rendah, wesi tuang, tembaga lan paduan aluminium sing mbutuhake kualitas permukaan sing kurang.
Suku cadang mesin casting baja paduan khusus deningproses casting investasi lilin ilangkaro kaca banyu (larutan natrium silikat) minangka bahan pengikat kanggo nggawe cangkang. Kualitas cangkang nggawe pengaruh akurasi casting final lan mulane proses kritis banget sak casting investasi. Kualitas cangkang langsung ana hubungane karo roughness lan toleransi dimensi saka casting final. Mulane, iku tugas penting kanggo pengecoran casting investasi kanggo milih cara Manufaktur cocok kanggo Nihan jamur.Miturut macem-macem adhesives utawa bahan binder kanggo nggawe cangkang jamur, cetakan casting investasi bisa dipérang dadi cangkang adhesive kaca banyu, cangkang adhesive silika sol, cangkang adhesive etil silikat lan cangkang komposit etil silikat-silika sol. Cara modeling iki minangka cara sing paling umum digunakake ing casting investasi.
Mould Shell dening Water Glass (larutan natrium silikat)
Casting investasi sing diprodhuksi dening casting cangkang kaca banyu nduweni kekasaran permukaan sing dhuwur, akurasi dimensi sing kurang, siklus nggawe cangkang sing cendhak lan rega sing murah. Proses iki digunakake digunakake ing casting baja karbon, baja alloy kurang, alloy aluminium lan alloy tembaga.
Mould Shell dening Silica Sol Shell (dispersi partikel silika skala nano ing banyu utawa pelarut)
Casting investasi silika sol nduweni kekasaran sing kurang, akurasi dimensi sing dhuwur, lan siklus nggawe cangkang sing dawa. Proses iki akeh digunakake ing casting alloy tahan panas suhu dhuwur, casting baja tahan panas, casting stainless steel, casting baja karbon, casting alloy kurang, casting alloy aluminium lan casting alloy tembaga.
Mold Shell dening Ethyl Silicate Shell
Ing casting investasi, casting digawe kanthi nggunakake etil silikat minangka binder kanggo nggawe Nihan duwe roughness lumahing kurang, akurasi dimensi dhuwur, lan siklus Nihan-nggawe dawa. Proses iki akeh digunakake ing casting alloy tahan panas, casting baja tahan panas, casting stainless steel, casting baja karbon, casting alloy kurang, casting aluminium lan alloy tembaga.
Baja karbon, baja paduan rendah, lan casting baja alat digunakake ing sawetaraaplikasi industrilan lingkungan. Kanthi akeh gelar, baja lan paduane bisa diolah kanthi panas kanggo nambah asil lan kekuatan tarik; lan, nyetel atose utawa ductility kanggo kabutuhan aplikasi engineer utawa sifat mechanical dikarepake.
Casting investasi baja paduan tahan nyandhang yaiku bagean casting sing diprodhuksi dening proses casting investasi lilin sing ilang digawe saka baja paduan tahan nyandhang. Ing RMC Foundry, pangolahan wedhi casting utama kita bisa digunakake kanggo nyandhang-tahan baja alloy sing wedhi casting ijo, resin ditutupi wedhi casting, ora-panggang wedhi cetakan casting, ilang casting umpluk, vakum casting lan investasi casting. Perawatan panas, perawatan permukaan lan mesin CNC uga kasedhiya ing pabrik kita miturut gambar lan syarat sampeyan.
Ing antarane macem-macem paduan casting, baja tuang sing tahan nyandhang minangka baja paduan sing akeh digunakake. Wear-resistant cast steel utamané mbenakake resistance nyandhang saka casting baja kanthi nambah isi beda unsur alloying, kayata manganese, kromium, karbon, etc., kanggo alloy. Ing wektu sing padha, resistance nyandhang saka castings baja nyandhang-tahan uga gumantung ing cara perawatan panas digunakake dening pengecoran lan struktur casting.
Miturut karakteristik nyandhang beda, nyandhang casting baja bisa dipérang dadi nyandhang abrasive, nyandhang adhesive, nyandhang lemes, nyandhang karat lan nyandhang fretting. Casting baja tahan nganggo utamane digunakake ing lapangan industri kanthi kahanan kerja sing kompleks lan syarat kinerja mekanik sing dhuwur, kayata pertambangan, metalurgi, konstruksi, tenaga, petrokimia, konservasi banyu, pertanian lan industri transportasi. Casting baja tahan nganggo biasane digunakake ing kondisi abrasion kanthi beban impact tartamtu, kayata peralatan grinding, excavator, crusher, traktor, lsp.
