Each roller handling units will be control by Variable Frequency Devices (VFD). 辊道 A8末端设有终端挡板。 各段装料辊道采用分组变频调速控制。 Final characteristics will be decided by parties during basic 方讨论确定。 The slab meant to be charged into furnace is prepositioned on the slab charging table. The charging machine pushes the slab forward for squaring it perpendicular to the furnace longitudinal axis. The charging operation itself is described under point – charging machine. 准备装入到加热炉的板坯先在装料辊道上预定位，然后装钢机向前推动板坯，以使板坯与炉子轴线垂直。 这个装料操作将在下面的装钢机一节中具体描述。 Charging machine 装钢机 Description 描述 Please refer to drawing 17 3027 A 0120 4 P 0001 Charging machine 参见图纸 17 3027A01204P0001 装钢机 Charging machines in front of the furnaces 1,2 and 3 are same. The type of machine we are proposing is based on equipment we have already supplied to other customers. 三座炉子的装钢机相同，这种结构型式的装钢机，已经成功的在其它项目中得到应用。 It consist in built transfer car, which made of a braced type horizontal rectangular shape / D – HANDAN ANNEX 2 Section A / 6 structure equipped with idle wheels at each corner and running at the front on 2 rails laid on beams fixed on the civil work and at the back inside a U profile fixed to the civil work on the ground. 它由一个带托臂的活动台车和两组固定轨道构成。 台车是一种带支撑的牢固的平行四边形框架结构，前部两边配备 2 个从动轮，从动轮在分别固 定于基础上的 2 条轨道上运动；后部两边也配备 2个从动轮，这组从动轮在分别固定于基础上的 2个 U型结构轨道上运动。 On the car are hinged 4 fingers which front part are nearly horizontal. Rotating axis of each finger is around one horizontal shaft placed perpendicular to the axis of the furnace. The rotation movement of the fingers, which function is to lift or lay down the product to be handled, is through hydraulic cylinders placed at the rear part of the fingers in a nearly vertical position. The lifting of the fingers is carried out by actuator hydraulically synchronised. Each actuator is used for 1 fingers. Each finger includes supporting plates bolted to the finger. 在台车框架上铰接有 4 个托臂，托臂接触板坯的部分几乎是水平的。 每个托臂的旋转轴线都在与炉子轴线垂直的一个水平面上，托臂的旋转运动完成板坯的提升或下降功能，它通过位于托臂后部几乎与之垂直的液压缸完成。 每 1 个托臂的运动由一个液压缸驱动。 每个托臂包括锚固在托臂上的支撑底板。 The lifting position control of the fingers is made through limit switches or proximity switches and linear transducer. 托 臂的提升位置控制通过限位开关 /或接近开关及线形位移传感器完成。 When handling one product for a single row charging in the furnace, 4 fingers of both parts are lifted together. When handling one product for a double rows charging in the furnace, 2 fingers of each parts are operated independently and only fingers of the part holding a product is operated. 当单排装料时， 4 个托臂同时提升。 当双排装料时，两侧各 2 个托臂分别操作，只有装坯料的 2个托臂有抬起动作，另 2个托臂处于下位。 Drive, forward or backward of transfer car is through two rack and pinion drives placed on the sides of the car. The two pinions of car are connected through a speed reducer to one single electrical motor placed either at the side or in the middle of the frame. The position control is made through encoder. 台车框架的向前、向后运动是通过放置于两侧的两个齿轮齿条驱动的，齿轮通过万向节连至电机驱动的减速器 ， 电机 减速机单元位于框架的侧面或中间。 台车 框架的定位控制， 由编码器完成。 The machine should be able, in exceptional circumstances to withdraw a product from the furnace. This would only be done under manual mode under the responsibility of the operator. 在特殊情况下，装钢机能将板坯从炉内取出。 这种功能只能由操作者手动完成。 The machine is designed for the heaviest slab (40 tons) and the individual overloading on each arm due to the dimension tolerances of the slab is taken into account. 装钢机按提升最重的板坯（ 40 吨）设计，并考虑到板坯的尺寸公差所带来的单个装钢臂的超载能力。 The lubrication of the bearings is connected to the central greasing station. The lubrication of the pinion and rack is manual and the regularly control is described in the / D – HANDAN ANNEX 2 Section A / 7 maintenance manual. 除齿轮齿条及轨道采用人工手动润滑外，其余运动部位采用集中润滑。 Main characteristics主要特性参数 Number of lifting fingers提升托臂数量 ............................................................................ 4 Finger steel grade托臂材质 ....................................................................................
