文档介绍：摘要
钢铁企业以其特有的生产方式和特有的原料与产品,使其与称重计量有着密不可分的联系。在钢铁企业里的所有计量工作中,称重计量放在重中之重。而在我国工业企业里唯有冶金企业对称重计量要求更为突出。抓好冶金企业的称重计量工作是冶金生产顺行与发展的需要。
本设计主要是对钢坯提升机称重液压系统的设计。其液压系统中的执行机构动作和系统的稳定将直接影响到称重精度,如果液压系统中的执行机构出现不稳定或者液压系统出现不稳定将会对称重精度和设备带来严重的后果。根据对钢坯提升机称重液压系统工艺要求,在生产过程中液压系统要完成以下动作,液压缸:快速提升;液压缸:缓慢提升;液压缸:停止(电子称重设备称重);液压缸:缓降;液压缸:快降;液压缸:停止(完成一个称重周期)。
钢坯提升机称重系统主要是轧钢厂用于称量进入加热炉钢坯的重量,以便为检查、分析钢坯在加热过程中的烧损情况,而为精确计算成材率,提供参考数据的装置。
考虑由于钢坯表面的氧化皮受提升机振动的影响而脱落在压力应变电阻片(电子称重设备)上,影响称重精度,导致其不能正常使用。采用钢坯提升机称重系统能很好的处理由钢坯氧化脱落带来的影响。
几亿吨的铁矿石和辅料,经过多道工艺周转变成近亿吨钢材,每一步都承受着巨额计量。从排岩到采矿,从磨矿到选矿和铁精矿输出,从烧结的配料到烧结矿的输出,从炼铁的配料到铁水的输出,从炼钢的配料到连铸坯的形成,钢材的轧制与输出,它们承受着最大的计量数额。

Abstract
Iron and steel enterprises with its unique mode of production and unique raw materials and products to match the weight measurement is inextricably linked. Weight measurement on the top priority in all metrological work in the iron and steel enterprises. Only metallurgical enterprises in China's industrial enterprises, more prominent weight measurement requirements. Anterograde and development of metallurgical production needs to grasp the weight measurement of the metallurgical enterprises.
This design is the design billet hoist weighing the hydraulic system. Executive body movements and stability of the system in its hydraulic system will directly affect the weighing accuracy, if the implementing agency in the hydraulic system instability or hydraulic system instability will have serious consequences for weighing accuracy and equipment. Billet upgrade a machine weighing hydraulic system process requirements, the hydraulic system plete the following actions in the production process, hydraulic cylinders: rapid promotion; hydraulic cylinder: slow improvement; hydraulic cylinder: stop (electronic weighing equipment, weighing); hydraulic cylinder : slow down; hydraulic cylinder: quick drop; hydraulic cylinder: stop (completion of a weighing cycle).
The billet hoist weighing system is to enter the weight of the furnace an
