我厂Φ500三辊式开坯轧机自1970年开始使用固定式卫板代替通常使用的活动式卫板,几年来的生产实践表明,这是一项很有价值的技术革新:使卫板的储备量和消耗量大为降低,简化了生产准备工作;减少了顶卫板、顶导卫梁、顶升降台、顶翻钢板等恶性事故,因而提高了轧机作业率,增加了轧钢工人操作的安全因素,深受工人群众的欢迎。固定式卫板结构简单,容易制作,便于推广。全国中型三辊式开坯轧机数量甚多,如果广泛采用固定式卫板,将会取得显著的经济效果。本文简述改进前的情况及固定式卫板的制作、使用经验,以供有关单位参考。
The Φ500 three-roll open mill of our factory has been using the fixed type board instead of the commonly used movable type board in 1970. The production practice in recent years shows that it is a valuable technological innovation: Greatly reducing the amount of production and consumption, simplifying the production preparation work; reducing the top guard, top guide Wei Ding, top lift table, the top turn steel and other serious accidents, thereby increasing the rolling mill operating rate and increase the safety of steel rolling workers Factors, welcomed by the workers. Fixed health board structure is simple, easy to make, easy to promote. The number of medium-sized three-roll tandem mills in the country is very large. If the fixed type of health boards are widely used, significant economic results will be achieved. This article describes the situation before the improvement and the production of fixed health board, the use of experience for reference for the relevant units.
