Q1: Steel balls are manufactured byA sintering
B casting
C cold heading
D spinning
ANS:C - cold heading Steel balls are typically manufactured by the process of cold heading. Cold heading, also known as cold forming or cold forging, is a manufacturing process used to shape metal parts at room temperature by applying high pressure. In the case of steel balls, the process involves feeding steel wire or rod into a cold heading machine, where it is cut into blanks of the desired length. These blanks are then subjected to high pressure in dies or molds, which shape them into spherical forms resembling balls. The pressure exerted during cold heading causes the metal to flow and take the shape of the die cavity, forming the spherical shape of the balls. Cold heading is a highly efficient and cost-effective method for mass-producing small to medium-sized steel balls with consistent dimensions and properties. The resulting steel balls are commonly used in various applications, including bearings, automotive components, and machinery parts. |
