Usoro mmepụta na nhazi usoro nke tungsten carbide rods

E nwere ụzọ abụọ akpụ maka mmepụta nke tungsten carbide gburugburu ogwe: otu bụ extrusion, na extrusion bụ ụzọ kwesịrị ekwesị iji mepụta ogologo ogwe.Enwere ike ịkpụ ya n'ogologo ọ bụla onye ọrụ chọrọ n'oge usoro extrusion.Otú ọ dị, n'ozuzu ogologo enweghị ike gafere 350mm.Nke ọzọ bụ mkpakọ ịkpụzi, nke bụ ụzọ kwesịrị ekwesị na-emepụta obere mmanya ngwaahịa.Dị ka aha ahụ na-egosi, a na-agbanye ntụ ntụ carbide cimented n'ụdị ya na ebu.

Cemented carbide nwere usoro magburu onwe ya dị ka ike siri ike, na-eyi nguzogide, ike dị mma na ike siri ike, okpomọkụ na-eguzogide, nguzogide corrosion, karịsịa elu ya siri ike ma na-eyi nguzogide, nke na-anọgide na-agbanwe agbanwe ọbụna na okpomọkụ nke 500 ° C, ma ka na-agbanwe agbanwe. nwere ike dị elu na 1000 Celsius.A na-eji Tungsten carbide eme ihe n'ọtụtụ ebe dị ka ihe eji eme ihe, dị ka ngwaọrụ ntụgharị, ndị na-egwe ọka, ndị na-egbutu osisi, ndị na-akpụ akpụ, ndị na-akụ ihe na-agwụ ike, wdg, maka igbutu ígwè, ọla ndị na-adịghị ferrous, plastik, eriri kemịkalụ, graphite, iko, nkume na ndị nkịtị. ígwè, na nwekwara ike iji bee okpomọkụ na-eguzogide ígwè, igwe anaghị agba nchara, nnukwu manganese ígwè, ngwá ọrụ ígwè na ihe ndị ọzọ siri ike mmiri egweri (bọl igwe nri, ihicha kabinet, Z-mixer, granulator ---), ịpị (na akụkụ. nrụgide hydraulic press ma ọ bụ extruder), --- sintering (ọkụ degreasing, ọkụ agbakwunyere ma ọ bụ HIP obere ọkụ ọkụ).
