Each roller handling units will be control by Variable Frequency Devices (VFD). 輥道 A8末端設(shè)有終端擋板。各段裝料輥道采用分組變頻調(diào)速控制。 Final characteristics will be decided by parties during basic 方討論確定。 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. 準備裝入到加熱爐的板坯先在裝料輥道上預(yù)定位，然后裝鋼機向前推動板坯，以使板坯與爐子軸線垂直。這個裝料操作將在下面的裝鋼機一節(jié)中具體描述。 Charging machine 裝鋼機 Description 描述 Please refer to drawing 17 3027 A 0120 4 P 0001 Charging machine 參見圖紙 17 3027A01204P0001 裝鋼機 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. 三座爐子的裝鋼機相同，這種結(jié)構(gòu)型式的裝鋼機，已經(jīng)成功的在其它項目中得到應(yīng)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. 它由一個帶托臂的活動臺車和兩組固定軌道構(gòu)成。臺車是一種帶支撐的牢固的平行四邊形框架結(jié)構(gòu)，前部兩邊配備 2 個從動輪，從動輪在分別固 定于基礎(chǔ)上的 2 條軌道上運動；后部兩邊也配備 2個從動輪，這組從動輪在分別固定于基礎(chǔ)上的 2個 U型結(jié)構(gòu)軌道上運動。 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. 在臺車框架上鉸接有 4 個托臂，托臂接觸板坯的部分幾乎是水平的。每個托臂的旋轉(zhuǎn)軸線都在與爐子軸線垂直的一個水平面上，托臂的旋轉(zhuǎn)運動完成板坯的提升或下降功能，它通過位于托臂后部幾乎與之垂直的液壓缸完成。每 1 個托臂的運動由一個液壓缸驅(qū)動。 每個托臂包括錨固在托臂上的支撐底板。 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過限位開關(guān) /或接近開關(guān)及線形位移傳感器完成。 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. 當單排裝料時， 4 個托臂同時提升。 當雙排裝料時，兩側(cè)各 2 個托臂分別操作，只有裝坯料的 2個托臂有抬起動作，另 2個托臂處于下位。 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. 臺車框架的向前、向后運動是通過放置于兩側(cè)的兩個齒輪齒條驅(qū)動的，齒輪通過萬向節(jié)連至電機驅(qū)動的減速器 ， 電機 減速機單元位于框架的側(cè)面或中間。 臺車 框架的定位控制， 由編碼器完成 。 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. 在特殊情況下，裝鋼機能將板坯從爐內(nèi)取出。這種功能只能由操作者手動完成。 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. 裝鋼機按提升最重的板坯（ 40 噸）設(shè)計，并考慮到板坯的尺寸公差所帶來的單個裝鋼臂的超載能力。 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. 除齒輪齒條及軌道采用人工手動潤滑外，其余運動部位采用集中潤滑。 Main characteristics主要特性參數(shù) Number of lifting fingers提升托臂數(shù)量 ............................................................................ 4 Finger steel grade托臂材質(zhì) ....................................................................................
