According to the characteristics and technical conditions of the gray iron casting, the position of the casting system is preferentially introduced, and then the section size of each unit of the casting system is calculated. In the calculation, first determine the small section size of the casting system, the small section of the closed casting system in the inner runner, the small section of the open casting system, a certain flow blocking section before the inner runner, and then according to the empirical proportional relationship , determine the cross section of other units. The size of the gating system varies with the structure of the gray iron casting, the casting of the machine bed and the specific production conditions. Therefore, the results of the calculation should be corrected in light of the specific circumstances and production experience.
