板坯连铸机垛卸板机设计
摘要
连续铸钢是五十年代以来在钢铁工业中发展起来的一项重大新技术。连续铸钢是将钢水连续注入结晶器，待钢水凝固成一定厚度的坯壳后，从结晶器下口拉出活底（引锭链），这样，铸钢坯就连续从结晶器下口被拉出来。这种将高温钢水直接浇注成钢坯的新工艺就是连续铸钢，简称“连铸”。
常规的连铸出坯后，由吊车将钢板一块块运入成品库，劳动时间较长，劳动量大而且比较频繁。
本次设计的垛卸板机则是对连铸出坯精整系统中以上的一系列弊端进行改良和创新而设计的一台连铸出坯系统中堆垛钢板的设备。
垛卸板机是个升降机械，由去毛刺机和打号机出来后的板坯在运输轨道上，由推钢机将钢板推送到垛卸板机升降台上，每堆垛一块钢板后，升降台下降一个板坯厚度，直到堆垛4块板坯后，由吊车将板坯吊运到成品库中。
设计中采用齿轮与齿条传动方案，来实现将旋转运动转变为直线运动。
本次垛卸板机的设计，设计内容包括:电动机的选择、传动比的分配、联轴器的选择、齿轮与轴的计算及强度校核等。减化了连铸生产出坯系统中的工艺流程，改善了劳动条件的同时，减少了工人的劳动时间及其劳动强度。

The unloader of the continuous slab casting
Abstract
Continuous cast steel has developed a major new technology in iron and steel industry in the 1950s. Continuous cast steel is molten steel continuous infusion crystallizer when molten steel curdle into a shell thickness of unburnt earthenware, pulled live from the mouth of the crystallizer (from 120,000 chain), so that continuous cast billet on the mouth pulled out from under crystallizer. That this will involve high-temperature molten steel directly into the new craft is continuous cast steel billet, short for "continuous metal casting."
Conventional continuous metal casting out unburnt earthenware, the cable car will be a piece of metal pieces into Chengpinku, longer working hours, labor and the large volume of relatively frequent.
The interior design of this machine is for continuous metal casting off panels of unburnt earthenware finishing system over a series of improvement and innovation and design defects in the system, one Taiwan continuous metal casting out unburnt earthenware piling steel equipment.
Stack dumping board aircraft is a mechanical movements from and to burr plane hit out of the plane after banpi in transport tracks from the plane onto steel plates push to stack dumping aircraft landing platform boards, a piece of steel per pile , a drop-Taiwan banpi thickness until piling pieces banpi 4, the cable car will be lifted to Banpi Chengpinku.
Used gear and spline drive design programmes to achieve rotary movement into linear movement.
This pile dumping board aircraft development, been greatly simplified the production of continuous metal casting unburnt earthenware system, given that a significant improvement in the working conditions, while reducing the working hours of workers with the labor intensity in continuous metal casting workshop for trial installation and commissioning achieved expected results and their purpose.
Keywords : continuous cast steel, a unburnt earthenware system ,stack dumping boards plane.
