Camshaft working conditions and materials The camshaft is a component in a piston engine. Its function is to control the opening and closing of the valve. Although the speed of the camshaft in a four-stroke engine is half that of the crankshaft (in a two-stroke engine, the speed of the camshaft is t... read more
Continuous casting billet evaluation index Evaluation index To evaluate the quality of continuous casting and rolling billets, there are four main indicators, namely, the geometry of the cast billet, surface quality, internal structure density and steel cleanliness. The quality of these four indicat... read more
High temperature embrittlement characteristics of continuous casting billet steel Among the defects of continuous casting slab, various surface and internal cracks account for a considerable proportion. The occurrence of cracks is mostly related to the high temperature characteristics of steel and v... read more
Classification and defects of continuous casting billets From the appearance, it is mainly divided into the following types: Slab: The ratio of cross-section width to height is large, and it is mainly used for rolling plates. Billet: the cross-section width and height are equal, or the difference is... read more
Camshaft modification and production technology Refit In order to improve the power of the engine, some refit shops have refitted the camshaft of the engine. Among them, the high-angle camshaft camshaft (Hi-CAM) is a common modification method. This modification operation is not complicated, but bec... read more
