Having a cold shock camshaft blank can be terrifying. Survivors have nightmares for months and sometimes even years. Survivors are unable to go near a board or boat for a long time. So how does the forged fibre flow get created? Firstly, a camshaft blank must be forged. Secondly, the blank must be heated. Then a sequence of cams is forged. The cams have to be formed in a sequential order starting from the central cam.
The cams are formed on a cam-forming portion of the blank, on the outer peripheral surface. The cams have to be made of the utmost quality. It is also important to have a high-frequency heater to maintain the temperature of the blank. Lastly, the heating temperature must be within the range of the forging temperature. The heating temperature distribution curve is a good reference for determining the heating temperature of a blank.
Using the correct heating temperature is important to ensure that the cams are formed correctly. The temperature of the molten iron directly affects the burning loss of inoculant. Hence, the heating temperature of a camshaft blank must be controlled within the range of the forging temperature.
To create the aforementioned cold shock layer, the camshaft blank must have a sufficient width. The thickness of the cold shock layer is determined by the width of the cam and the height of the cam. A camshaft blank with a high top height will require a thicker chill.
