Chii chinonzi tungsten carbide composite rods?

Tungsten carbide composite tsvimbo yakagadzirwa necemented carbide matipi uye Ni/Ag(Cu) alloy. Iwo matipi ecarbide anogara ari tungsten carbide yakapwanyika grits, carbide kupfeka inoisa, senge carbide nyeredzi chimiro chinoisa, carbide piramidhi chimiro chinoisa, shark chimiro chinoisa, zvichingodaro. Dzimwe nguva, iyo carbide matipi anogona kuve tungsten carbide poda. Sarudzo yehupfumi ndeye tungsten carbide yakapwanyika grits. Kana iwe uchida kukwirisa kusimba kupfuura carbide grits, carbide inoisa iri nani. Nekudaro, iyo simende carbide / yakapwanyika carbide ine inopinza mupendero ine yakanakisa kupfeka kuramba uye kugona kucheka zvakare.

Kuoma kwe89-91 HRA, binder simbi iNi uye copper alloy, simba rinogona kusvika pa690MPa, kuoma HB≥160.

Kupfupisa, akawanda eComposite tsvimbo dzakagadzirwa neyakapwanyika sintered Tungsten Carbide tsanga dzakasungwa nebronze nickel matrix, (Cu 50 Zn 40 Ni 10) ine yakaderera kunyungudika (870°C).

Sei uchishandisa tungsten carbide grits sechinhu chikuru

Isu tese tinoziva tungsten carbide ine kuoma kwakanyanya,Tungsten carbide ine kuita kwakanaka muSimbi yekucheka.Tungsten carbide grits ane kupfeka kupikisa zvimiro. Tungsten carbide grits inogona kuchengetedza pamusoro pezvishandiso zviri pasi pekupfeka abrasive. Tungsten carbide mazano raisekukurumidza kwekuchera pasi nekucheka,kuchengetedza geji yakazara pazvinodzikamisa, magidhi ekuwipa makiyi ezvigaro, uye mamwe maturusi ekudzika.

Magiredhi ematanda akaumbwa

Magiredhi maviri makuru anoenderana neakasiyana Zvikamu zve tungsten carbide grits

1. Giredhi rekucheka:70% tungsten carbide + 30% binder

2. Kupfeka giredhi:60% tungsten carbide + 40% binder
