gongbao Zh一eheng zhuongzhi钢包支承装置(ladle supporting equipment) 支承盛钢捅(钢包)进行浇注的连铸设备。有钢包支架,钢包车和钢包回转台等多种类型。 钢包支架最简单的钢包支承装置,由钢结构焊接而成。它只能支承钢包,不能使之升降和回转,因而不便于迅速更换钢包和采取钢流保护措施,只能用于同跨浇注和单炉浇注以及浇注一般用途的钢种。 钢包车有门式和半门式两种结构,可用于同跨和过跨浇注。门式钢包车可在浇注平台上设置的两条轨道上行走,钢包也可以升降。半门式钢包车是门式钢包车的一种改进型,它的一端车轮支承在厂房柱子或其他构件上,减轻了平台的负荷,并使平台空间开阔,改善了操作者的工作环境。 钢包回转台用得最为广泛的钢包支承装置。它的一个臂支承正在浇注的钢包,另一个臂可同时安放另一个钢包。钢包回转台运送、更换钢包极为灵活和方便,可以用于同跨和过跨浇注以及实现多炉连浇。钢包回转台的回转运动通常采用电动一机械方式,而升降运动采用液压方式。钢包回转台都备有事故回转驱动系统,采用液压马达或气动马达供给动力。大多数回转台的两个臂上装有用于钢水称量的压力传感器。钢包回转台有直臂式、单臂旋转式和单臂升降式等多种型式。(见彩图插页第21页) 直臂式钢包回转台两个臂组成一个刚性结构,同时作旋转运动和同时升降。也可在两个臂的钢包支座下加液压缸实现两个臂的钢包单独升降。直臂式钢包回转台结构简单(见图1),维修方便,制造成本低,应用广泛。兮牛 图1直臂式钢包回转台 1一钢包;2一传动装置;3一支承座;4一承载臂 单臂旋转式钢包回转台它的两个臂为两个独立的构件,分别安装,可以单独旋转。(见图2)这种回转台操作灵活,一个臂上的钢包正在浇注时,另一个臂可在任意角度接受另一个钢包,因而特别适用于连铸机纵向布置的车间。这种形式的回转台结构复杂,制造成本较高。 单臂升降式钢包回转台亦称蝶形回转台。它的两个臂可以单独升降和同时回转。这种回转台一般用于大容量钢包的支承和浇注。(见图3)飞尹 图2单臂旋转式钢包回转台 1一支承臂;2一驱动装置;3一支承座;4一钢包ha 图3单臂升降式回转台 (俞姜)
