一、简况目前,耐火材料工业使用的成型设备主要是摩擦螺旋压砖机。此种设备有许多缺点,它们是:安全性差、劳动强度大、耗电量大、维修工作量大和设备难于实现自动化等。针对这些缺点,采用直线电机技术来改造其传动机构,制成一种新型的耐火砖成型设备,称之为电磁螺旋压砖机。它不但克服了上述各项缺点,并提高了耐火砖压制质量,效果 I. Introduction At present, the molding equipment used in the refractory industry is mainly a friction screw press. There are many disadvantages to this type of equipment. They are: poor safety, high labor intensity, large power consumption, large maintenance workload, and difficulty in automating the equipment. In response to these shortcomings, linear motor technology is used to transform its transmission mechanism and a new type of refractory brick molding equipment is made, which is called an electromagnetic screw press. It not only overcomes the above shortcomings, but also improves the quality of refractory bricks.
