Uhlalutyo lokuba kutheni umlomo wesitofu ubambekile kwizitofu (icandelo 2)

2.2 Uburhabaxa bomphezulu kunye neziphumo zomlinganiso wobulukhuni Uburhabaxa bomphezulu bevalve yenaliti iyalinganiswa, kwaye imfuneko yokurhabaxa komphezulu wevalve yenaliti yi-61HRC～65HRC yemfuneko yobulukhuni bomphezulu. Uburhabaxa bevalve yenaliti enenombolo yesitampu sentsimbi i-HHM yiRa0.03, Rt0.34, kunye nobunzima bomhlaba yi-60.4HRC～60.7HRC; ivalve yenaliti enesitampu sentsimbi HD yiRa0.02, Rt0.37, kunye nobunzima bomhlaba yi-62.3HRC. Uburhabaxa kunye nokuqina kweevalvu zeenaliti ezimbini ezingeniswe ukuba zihlolwe zonke ziyahlangabezana neemfuno zoyilo. Emva kokuba i-nozzle ihlulwe, uburhabaxa bomngxuma ongaphakathi bulinganiswe. Uburhabaxa bomngxuma ongaphakathi bombhobho wawuyi-0.05Rt0.8. I-Valve Ra0.07～1.16, i-Rt0.82-1.79. Uburhabaxa bomngxuma wangaphakathi wemilomo emibini engeniswe ukuba ihlolwe ayikhange ihlangabezane neemfuno zoyilo.

2.3 Umlinganiselo wobunzima bomphezulu kunye neziphumo zokuhlalutya i-metallographic Ukuqina komphezulu wevalve yenaliti kufuneka kube yi-61HRC-65HRC, i-bainite yamahhala ayivumelekanga, kwaye i-austenite eseleyo ayidluli kwi-5%. Ukuqina kwevalve yenaliti enenombolo yesitampu sokuqala i-HHM yi-62.9HRC～63.6HRC, ubungakanani beenkozo yi-10, kunye neqondo lobushushu obukhulu yi-2; ukuqina kwevalve yenaliti enenombolo yokuqala yesitampu sentsimbi HD yi-62.4HRC～63.4HRC, ubukhulu bengqolowa yi-9, kunye ne-degree of superheat yi-2. Ubunzima beentsimbi ezimbini zeenaliti zonke zihlangabezana neemfuno zokuyila.
