一、概述随着铸造生产机械化和自动化的发展,近年来造型线的生产率提高到240～300型/h,型砂的需要量相应增加到60～300t/h。这要求砂处理系统要能够处理如此大的砂量,并要有一定的可靠性、灵活性及与造型线相协调的连续性,这也是大量生产的铸造车间砂处理系统应具备的四个特点。 I. Overview With the development of mechanization and automation of foundry production, the productivity of molding lines has been raised to 240-300 / h in recent years, and the requirement for molding sand has been correspondingly increased to 60-300t / h. This requires sand processing system to be able to handle such a large amount of sand, and have a certain degree of reliability, flexibility and consistency with the molding line continuity, which is mass production of sand casting system should have four characteristics .
