德国曼内斯曼德马克公司现推出板坯连铸机用在线双向宽度连续调节的结晶器。这种结晶器的宽度调节是由两个相互独立的分别由三相伺服电动机驱动的可调螺旋斜齿轮传动窄面板移动达到的。可采用三种方式在线调节宽度即自动、人工和计算机调节。窄面板的调节控制装置采用了新的驱动方式。到目前为止,结晶器窄面板的精确定位是由安装在电动机外的电子位置转换系统控制的。这些电子元件受到高温、水蒸气和强腐蚀性氢氟酸的严重威胁,易于损坏。而新的驱动控制装置安装处远离热源,改善了电子元件的工作环境。这种驱动控制装置是由一个称为“解算器”(Resolver)的元 Mannesmann Demark, Germany, is introducing the crystallizer for slab caster continuous line bi-directional width adjustment. The width adjustment of this mold is achieved by the movement of two separate adjustable helical bevel gears driven by three-phase servomotors. There are three ways to adjust the width online: automatic, manual, and computerized. Narrow panel adjustment control device uses a new drive. Until now, the precise positioning of narrow mold plates has been controlled by electronic position-shifting systems installed outside the motor. These electronic components are subject to high temperatures, water vapor and corrosive hydrofluoric acid serious threat, easy to damage. The new drive control device installed away from heat, improve the working environment of electronic components. This drive control unit is made up of a meta-element called the Resolver
