Lithupa tse kopantsoeng tsa tungsten carbide ke eng?

Tungsten carbide composite rod e entsoe ka malebela a samente ea carbide le Ni/Ag(Cu)alloy. Malebela a carbide e lula e le li-grits tse silafetseng tsa tungsten carbide, li-carbide wear inserts, joalo ka li-carbide star shape inserts, carbide pyramid shape inserts, shark shape inserts, joalo-joalo. Ka linako tse ling, malebela a carbide e ka ba phofo ea tungsten carbide. Khetho ea moruo ke tungsten carbide e sithabetseng grits. Haeba u batla ho tšoarella ho feta li-grits tsa carbide, ho kenya carbide ho molemo. Leha ho le joalo, carbide e entsoeng ka samente / e sithabetseng e nang le bohale bo bohale e na le khanyetso e ntle ea ho apara le bokhoni ba ho itšeha.

Ho thatafala ke 89-91 HRA, tšepe e kopanyang ke Ni le motsoako oa koporo, matla a ka fihla ho 690MPa, boima ba HB≥160.

Ka bokhutšoane, boholo ba lithupa tse kopantsoeng li entsoe ka lithollo tse silafetseng tsa Tungsten Carbide tse kopantsoeng le matrix a nickel ea boronse, (Cu 50 Zn 40 Ni 10) e nang le ntlha e tlaase ea ho qhibiliha (870 ° C).

Hobaneng u sebelisa li-grits tsa tungsten carbide joalo ka thepa ea mantlha

Kaofela rea ​​tseba hore tungsten carbide e na le boima bo phahameng.Tungsten carbide e na le ts'ebetso e ntle ho seha ka tšepe.TUngsten carbide grits e na le thepa ea ho hanyetsa. Tungsten carbide grits e ka sireletsa bokaholimo ba lisebelisoa tse tlas'a ho roala ka maqeba. Tungsten carbide malebela raiselebelo la ho sila le ho rema sekoti,ho boloka li-gauge tse felletseng ho li-stabilizers, li-wiper tsa litulo tse tataisang, le lisebelisoa tse ling tsa ho thella.

Boholo ba lijo-thollo tsa grits ea carbide:

1/8-1/16 in. ( 3.2-1.6 mm)

3/16-1/8 in. (4.8-3.2 mm)

1/4-3/16 in. (6.3-4.8 mm)

3/8-5/16 in. (9.5-7.9 mm)

5/16-1/4 in. (7.9 -6.3 mm)

3/8-1/4 in. (9.5-6.3 mm)

1/2-5/16 in. (12.7-7.9 mm)

Mekhahlelo ea lithupa tse kopantsoeng

Limaraka tse peli tse kholo li ipapisitse le Likarolo tse fapaneng tsa grits ea tungsten carbide

1. Boemo ba ho itšeha:70% tungsten carbide + 30% binder

2. Boemo ba ho apara:60% tungsten carbide + 40% binder

U ka khetha limaraka tse fapaneng ho latela kopo ea hau.
