IiPropati zoomatshini kunye nezoMzimba zeTungsten Carbide

I-Tungsten carbide yi-alloy enento ephambili yomgubo oquka i-tungsten carbide, i-titanium carbide, kunye ne-metal powder efana ne-cobalt, i-nickel, njl njl, njenge-adhesive, efunyenwe nge-powder metallurgical method. Ikakhulu isetyenziselwa ukwenza izixhobo zokusika ngesantya esiphezulu kunye nezinto ezinzima, eziqinileyo zokusika imiphetho, kunye neendawo ezinxitywayo eziphezulu zokwenza izinto ezibandayo ezifayo, kunye nezixhobo zokulinganisa.

Iimpawu zoomatshini kunye nezomzimba ze-tungsten carbide

1. Ubunzima obuphezulu kunye nokuxhatshazwa kokugqoka

Ngokuqhelekileyo, phakathi kwe-HRA86 ~ 93, iyancipha ngokunyuka kwe-cobalt. Ukumelana nokunxiba kwe-tungsten carbide yinto ebaluleke kakhulu. Kwizicelo ezisebenzayo, i-carbides inamaxesha angama-20-100 ubude kunezinye i-alloys zensimbi ezinxitywayo.

2. Amandla aphezulu achasene nokugoba.

I-carbide ene-sintered ine-modulus elastic ephezulu kwaye i-bend encinci ifunyenwe xa iphantsi kwamandla okugoba. Amandla okugoba kubushushu obuqhelekileyo buphakathi kwe-90 kunye ne-150 MPa kwaye iphezulu i-cobalt, iphezulu amandla achasene nokugoba.

3. Ukumelana nokubola

Idla ngokusetyenziswa kwiindawo ezininzi zeekhemikhali kunye nezonakeleyo kuba iikhabhide ziqhelekile ukuba zingasebenzi ngokwekhemikhali. Iipropati zeekhemikhali ezizinzileyo. Izinto zeCarbide zine-asidi-resistant, i-alkali-resistant, kunye ne-oxidation ebalulekileyo nakwiqondo lokushisa eliphezulu.

4. Amandla e-torsional

Ubungakanani be-torsion buphindwe kabini kwintsimbi ye-high-speed kunye ne-carbide yinto ekhethwayo kwizicelo ze-high-speed operation.

5. Amandla acinezelayo

Amanye amabanga e-cobalt carbide kunye ne-cobalt asebenza ngokugqibeleleyo phantsi koxinzelelo lwe-ultra-high kwaye aphumelele kakhulu kwizicelo zoxinzelelo ukuya kwi-7 yezigidi ze-kPa.

6. Ukuqina

Amabakala e-carbide enziwe ngesamente anomxholo ophezulu we-binder anempembelelo entle yokuchasa.

7. Ukuxhatshazwa kweqondo lokushisa eliphantsi

Nokuba kubushushu obuphantsi kakhulu, i-carbide ihlala ilungile ukunxiba ukuxhathisa kwaye ibonelela ngee-coefficients ezisezantsi zokukhuhlana ngaphandle kokusebenzisa i-lubricant.

8. Thermoharding

Ubushushu be-500 ° C abutshintshanga kwaye kusekho ubunzima obuphezulu kwi-1000 ° C.

9. I-thermal conductivity ephezulu.

I-carbide ene-cemented ine-conductivity ephezulu ye-thermal kunokuba i-speed-speed steel, eyanda ngokunyuka kwe-cobalt.

10. I-coefficient yokwandiswa kwe-thermal incinci.

Iphantsi kune-high-speed steel, i-carbon steel, kunye nobhedu, kwaye inyuka ngokunyuka kwe-cobalt.
