设计简介
摘要
结晶器振动装置是连铸机的重要设备之一，起主要作用是使内壁获得良好的润滑条件，减少摩擦力，防止钢水与内壁的粘结，同时还可以改善铸坯的表面质量。而且当发生粘接时，振动能强制脱模，消除粘结。振动机构是使结晶器产生所需要的振动，因此任何振动机构都必须满足两个基本条件：第一，使结晶器准确地沿着一定的轨迹振动。第二，使结晶器按着一定的规律振动。
结晶器实现弧形运动轨迹的方式有：导轨式、长臂式、差动式、双摇杆式、四偏心式，以及液压振动机构等等。振动规律主要包括：同步式振动、负滑脱振动、正弦振动、非正弦振动等等。
短臂四连杆机构是通过选择适当尺寸的两个摇杆，使其在某一瞬间的运动是绕曲率半径中心的圆弧线运动。其中两摇杆长度的选择必须满足：①两摇杆的长度相等；②两摇杆的延长线通过曲率中心。
本说明书主要对短臂四连杆机构进行了设计，其内容如下：
① 连铸振动机构的简介、发展、运动形式和运动规律；
② 设计方案的确定；
③ 工艺参数的确定；
④ 振动机构的运动分析和电动机的选择；
⑤ 润滑与安装维护的确定；

Abstract
Crystal vibrator is one of important equipment of continuous casting machine, play a major role is to get a good wall lubrication, reduce friction, prevent adhesion of molten steel and the inner wall, while also improving the billets surface quality. And when bonding occurs, the vibration can be forced stripping, erased. Vibration body is needed to mold the vibration generated, so any vibration institution must meet two basic conditions: first, to mold accurately track down some vibration. Second, make sure the laws of the mold Anzhuo vibration.
Mold curved trajectory to achieve the way: DIN rail, the long arm-type, differential, dual rocker-style, four eccentric and hydraulic vibration institutions and more. Vibration law include: synchronous vibration, the negative slip vibration, sine vibration, non-sinusoidal vibration and so on.
Short arm of four-bar linkage is by selecting the appropriate size of the two rocker, to a certain moment of the campaign is centered around the radius of curvature of arc line movement. Two of the rocker length the choice must be met: ① equal to the length of the two rocker; ② the extension line through the two rocker curvature center.
The instructions on the short arm of the main bodies of the four-link design, which reads as follows:
①Vibration brief description of the continuous casting, development, form and movement law of motion;
②Determination of design;
③Process Parameters;
④Vibration of the kinematic analysis and motor selection;
⑤Lubrication, sealing and installation of adjustment methods to determine;
Keywords: continuous casting crystallizer vibrating mechanism
