mphete za simenti za carbide roll (zomwe zimadziwikanso kuti tungsten carbide roll ring) zili ndi zinthu zabwino zopangira matenthedwe. Poyerekeza ndi zida zina, ndizabwinoko pakukana kutentha, kukana kuvala komanso mphamvu. Komanso, kuuma kwake kumachepetsa pang'ono pansi pa kutentha kwakukulu. Choncho, mphete za simenti za carbide zimapangidwira ndi maonekedwe a mphero yothamanga kwambiri ya waya.
Ponena za zinthu zomwe timagulitsa, pali mitundu iwiri monga Wc-Co ndi Wc-Co-Ni-Cr yomwe ili ndi makina abwino ophatikizana. Mphamvu yopindika ndi kulimba kwamphamvu kumafika ku 2200 Mpa ndi (4-) x106J/ m' motsatana.Kulimba kwake ndi kukana kwake kumachokera ku tungsten carbide (Wc) pomwe kulimba ndi mphamvu zimadalira chomangirira (Co-Ni-Cr). Pakalipano, mphero yomaliza nthawi zambiri imakhala ndi masitepe 8-10. Chifukwa cha kukula kwakukulu kwa gawo lopindika, kolala yomwe ili kutsogolo kwa mphero imatha kukana kugwira ntchito molemera komanso kugunda mwamphamvu. Choncho, kuuma kwakukulu ndi kukana kwabwino kwa kutentha kwa kutentha ndizo zinthu zazikuluzikulu, zomwe zisanachitike kuvala-resistance.Ngakhale pali katundu wochepa komanso zotsatira zazitsulo zotsalira, tidzapereka chidwi kwambiri pa kukana kuvala ndi kutopa kwa kutentha kwa mpukutu. mphete. Pakali pano, mphero zomalizirira nthawi zambiri zimakhala ndi masitayilo 8-10. Chifukwa cha kukula kwakukulu kwa malo opindika, kolala yomwe ili kutsogolo kwa mpheroyo imatha kukana ntchito yolemetsa ndi kukhudza kwambiri. Choncho, kuuma kwakukulu ndi kukana kwabwino kwa kutentha kwa kutentha ndizinthu zazikulu, zomwe zisanachitike kuvala-kukana. tidzakhala ndi chidwi kwambiri ndi kuvala-kukana ndi matenthedwe kutopa kukana mpukutu mphete.
