1, Apa Casting Iron Kromium Dhuwur?

Wesi tuang kromium dhuwur yaiku singkatan saka wesi cast putih kromium dhuwur, yaiku bahan tahan nyandhang kanthi kinerja sing apik banget lan dihargai. Nduwe resistensi nyandhang sing luwih dhuwur tinimbang baja paduan, lan kekuwatan lan kekuatan sing luwih dhuwur tinimbang wesi tuang putih biasa. Ing wektu sing padha, uga nduweni resistance suhu dhuwur lan resistance karat. Kajaba iku, iku gampang kanggo gawé lan biaya Moderate, supaya dikenal minangka salah siji sing paling bahan nyandhang anti-abrasive ing jaman kontemporer. Wesi tuang kromium dhuwur umume nuduhake wesi tuang putih kanthi kandungan Cr 11-30% lan kandungan C 2.0-3.6%.

2. Karakteristik kinerja saka wesi cast kromium dhuwur

1) Wear resistance saka wesi cast kromium dhuwur

Wesi kromium sing dhuwur nduweni resistensi nyandhang sing apik lan minangka bahan gesekan sing apik. Bisa digunakake kanthi akeh ing pabrik bagean mekanik, kapal, lapangan minyak lan pengeboran lan lapangan liyane. Ketahanan nyandhang sing apik utamane amarga jumlah karbida kromium sing akeh ing struktur mikro internal. Karbida iki nduweni atose dhuwur lan kateguhan impact dhuwur, lan bisa kanthi efektif nolak nyandhang lan karat. Resistance korosi saka wesi cast kromium dhuwur

2) Fitur penting liyane saka wesi cast kromium dhuwur iku resistance karat banget.

Wis resistance banget kanggo macem-macem asam kuwat, alkalis kuwat lan ion klorida, lan digunakake digunakake ing sawetara kimia, Petroleum lan kothak liyane. Iki amarga unsur kromium ing wesi cast kromium dhuwur bisa mbentuk film protèktif kromium oksida kandhel, kang èfèktif ngindari invasi media korosif.

3) kinerja suhu dhuwur saka wesi cast kromium dhuwur

Wesi kromium sing dhuwur uga nduweni kinerja suhu dhuwur sing luar biasa. Bisa njaga atose dhuwur lan kekuatan kanggo dangu ing suhu dhuwur tanpa softening ketok, embrittlement lan fénoména liyane. Struktur mikro saka unsur kromium diganti ing suhu dhuwur, mbentuk film protèktif kromium oksida relatif lengkap, kang èfèktif nglindhungi kinerja materi.

5. Aplikasi kothak wesi cast kromium dhuwur

1) Iki digunakake ing pertambangan, semen, listrik, mesin konstruksi dalan, bahan refraktori, lan liya-liyane, lan umume digunakake ing piring lapisan, kepala palu, lan bahan werni nggiling. Sawise taun 1980-an, iki luwih akeh digunakake ing produksi kamar mesin blasting dijupuk lan blades mesin blasting lan piring lining, sing bisa nyegah balok projectile kanthi kacepetan dhuwur lan padhet saka penetrating cangkang piring baja.

2) Ing mesin pertanian, bahan wesi kromium dhuwur bisa digunakake kanggo ngasilake plowshares mesin pertanian, lsp.
