简介:摘要:对退火酸洗线活套保护和带钢、轧道最小长度精准计算,有效核算活套内保护开关的安装位,如正常停止(N-STOP)、快速停止(F-STOP)、紧急停止(E-STOP)、位置同步点(Position synchronization point)。每月检修定期检验安全保护动作的有效性和准确性,避免产线活套因某一道保护失效,而发生重大设备撞击事故;有力保障活套设备高效、安全、长期稳定运行。
简介:【摘要】《指南》健康领域目标指出:“幼儿园要开展丰富多样、适合幼儿年龄特点的各种身体活动,如走、跑、跳、攀、爬等,鼓励幼儿坚持下来,不怕累,激发幼儿参加体育活动的兴趣,养成锻炼的习惯。” 常言道:一天之计在于晨。晨间体锻是幼儿园一日活动的开始,也是幼儿园教育活动中一个必不可少的环节。 晨间体锻开展得好,能促使幼儿的精力更加充沛、心情更加愉悦、注意力更加集中,对于幼儿身体素质的提高、身心的健康发展,以及幼儿一日活动的情绪和状态都有着直接的影响。
