Zida za EQ491 injini camshaft ndi chromium-molybdenum alloy cast iron, ndipo kapangidwe kake kake kamawonetsedwa mu Gulu 1.
Table 1 Zomwe zimapangidwa ndi mankhwala ndi (%) za chromium-molybdenum alloy iron cast

Kapangidwe kazitsulo ka chromium-molybdenum alloy cast iron camshaft isanatenthedwe ndi mtundu wa B graphite + fine pearlite + mesh carbide.
Cam blank imayang’aniridwa ndi kutentha kwa induction quenching mu as-cast state. Zomwe zimafunikira pakuzimitsa ndi kuuma kwapamtunda kwa 50-60HRC, nsonga ya pichesi yolimba ya 4.6mm-10.0mm, ndi bwalo loyambira lolimba la 1.5mm-8.0mm.
