The thesis emphasis the way and arithmetic of the key equipment of walking reheating furnace : loader machine , unloader machine , walking system , series transfer roll , control system of burning and tracking of steel billet , . make use of the system , we can carry out the function of transferring measuring and weighting , detecting , loading and unloading tracking the steel billet , we can control process of burning and exchange data each other to track the steel billet and manage the process over all of product line . goals of reheating furnace ' s producing process such as high yield , low consuming and pollution , automatic operating mode are achieved 本文着重研究了步进式加热炉关键设备如：装钢机、出钢机、步进梁、炉前炉后辊道、燃烧控制、板坯物流跟踪等控制对象的具体控制软件流程、速度控制曲线、行程计算等具体控制策略和算法，完成了攀钢1450热轧加热炉基础自动化系统（ l1 ）和热工仪表的一级控制，实现板坯输送、测量、装出料、物流跟踪、加热炉燃烧控制以及板坯库的数据信息交换,通过plc和二级计算机系统进行顺序、定时、联锁与逻辑控制，实现了操作自动化与物料系统的全线跟踪管理。
Langfang jihua - trade fuels management company limited was established in 2006 , has been two years of coal sales history , major cities headquarters in beijing have large freight yard with a total area of 160 , 447 square meters , each package of road freight yard with all the machinery coal unloader missing , the coal and coal transport system , sprinkler irrigation equipment , are equipped with dedicated rail lines 廊坊冀华通贸燃料经营有限公司成立于2006年，至今已有2年煤炭销售历史，总公司在北京各大城市均有大型货场，总面积160447平方米，每个货场均拥有整套行进的机械缺卸煤、配煤系统和煤炭转运、喷灌设备，均配有铁路专用线。
In winter the outside temperature is - 15 ~ - 30 , the wet coal freezes seriously in transportation . the frozen coal thick is about 400mm , sometimes freezes to a whole one , the unloading work is extremely difficult , affects the turnover of coal train , possessing rail cars and the railway , makes the railway transport strength not be fully displayed . it has created national manpower , financial resource loss , but in domestic and foreign , the development of movable frozen coal unloader is the blank 在冬季北方室外平均气温在- 15oc ~ - 30oc ,湿煤在外运的过程中冻结现象严重,冻层厚在400mm左右,有时整车冻实,作业十分困难,影响运煤列车的周转,造成压车,压线现象,使铁路运力得不到正常的发挥,造成了国家人力,财力的损失,而国内外对于移动式卸冻煤机械的研制也是空白,为此急需研制一种能够卸冻煤的可移动式卸煤机。
A grab sway controlling scheme of bridge - type grab ship unloader is offered in order to increase productivity : first determines the desired trolley traveling speed chart to control the grab sway , then applies fast brake when the trolley approaches the hop and throws the material in the grab by the grab sway 摘要提出一种桥式抓斗卸船机抓斗有控摆动的策略，即通过小车运行速度曲线的设计控制抓斗摆动，并在小车接近料斗时快速制动，利用抓斗摆动抛出物料，以提高卸船机的生产率。
The frozen coal destruction is the tension stress destroys , and establish the frozen coal cutting model in this foundation , obtains the cutting force , feeding force , tooth spacing according to the smallest energy principle . bring forward a rotary drilling mothod to unload the frozen coal , the broken ability is strong , without frozen depth limits , then obtains this machine working parameters , has combined this method with a grab and determined the plane of vehicle - carried rotary drilling movable coal - unloader 冻煤破坏是拉应力破坏,在此基础上建立了冻煤的切削模型,根据最小能量原理得到截割力,进给力和截齿间距的计算公式,分析得到截割力与切削厚度成正比,随着前角的增大而减小;截齿最优截距与截齿尺寸有关且与切屑厚度成正比;进给力随着截齿前角增大而增大的规律。
