It is fitted with rails running on the transfer wheels. The transfer frame is made of welded Hsection beam. 平移框架用于固定支撐步進(jìn)梁和水封槽,并配有在平移滾輪上運(yùn)行的軌道。 Characteristics 主要性能 Number of lifting wheels提升滾輪數(shù)量 .......................................................................... 22 Number of transfer wheels平移滾輪數(shù)量 ...................................................................... 22 Material滾輪材質(zhì) ............................................... 42CrMo4 surface hardened表面硬化處理 Lifting frame 提升框架 Description 描述 The lifting frame consists of a set of beams connected to each other, in which wheels will be fixed. 提升框架由一組梁 組 成, 輪子固定在提升框架上 。爐子一側(cè)的滾輪形狀可以適應(yīng)提升框架在斜臺(tái)面上的 導(dǎo)向。 Characteristics 主要性能 Number of ramps 斜臺(tái)軌數(shù)量 ............................................................................ 11 pairs對(duì) Angle角度 .................................................................................................................. ~ 11176。 Idling movement of the walking beams 步進(jìn)梁中間保持 In the event of an extended stoppage of the mill, the walking beams switch to a holding mode where the moving beams position themselves at the same level as the fixed beams. In this way the stock is supported by all the beams. 當(dāng)軋機(jī)較長 時(shí)間停軋時(shí),步進(jìn)梁系統(tǒng)切換至長時(shí)待軋模式,此時(shí)活動(dòng)梁及固定梁處在同一水平位置,所有梁共同支撐著坯料。 Horizontal transfer movement 平移運(yùn)動(dòng) The transfer movement of the walking beams is achieved by means of a hydraulic cylinder, which acts directly on the upper frame, sliding over the upper rollers of the lower frame. During the transfer movement, the lift cylinders are locked. 步進(jìn)梁的平移運(yùn)動(dòng)是通過液壓缸直接作用于上部平移框架來實(shí)現(xiàn)的,平移框架沿提升框架的滾輪運(yùn)動(dòng)。升降運(yùn)動(dòng)時(shí),平移液壓缸鎖緊。 A speed to obtain a cycle of a total period which is consistent with the required charging and discharging rates. 獲得一個(gè)滿足所需要的裝出料速度的循環(huán)周期。所有運(yùn)動(dòng)都由線性位移傳感器來檢測,并被反饋至加熱爐的 PLC中。 The mechanical system is designed to allow manual back cycling. 所設(shè)計(jì)的步進(jìn)梁機(jī)械系統(tǒng)可以完成手動(dòng)逆循環(huán)動(dòng)作。坯料的緩慢提升、下降也可以防止支撐墊塊在坯料上形成印跡。 A slowdown period during lifting and lowering allows the stock to be gently lifted and lowered onto the beams, minimizing shock loads. This design prevents excessive stresses on the mechanical system, on the one hand, guarantees a linear conveyance of the stock through the furnace, on the other hand, and avoids damage to the refractory insulation through vibrations. Slowdown upon lifting and/or lowering of the stock also prevents the stock from being marked by the support pads on the longitudinal beams, 在提升及下降時(shí),有一個(gè)減速運(yùn)動(dòng)過程,保證坯料被輕輕地與支撐水梁接觸,減少?zèng)_擊負(fù)荷。 Thus, the walking beams perform a rectangular cycle which prises 4 basic movements at variable speed: upwards, forwards, downwards and backwards. 這樣,步進(jìn)梁將以不同的速度,完成一 個(gè)矩形周期運(yùn)動(dòng),包括四個(gè)動(dòng)作:上升、前進(jìn)、下降、后退。 / D – HANDAN ANNEX 2 Section A / 9 When the lift frame runs up and down the ramps, the transfer frame is motionless and the walking beams respectively move upwards and downwards (movements are strictly vertical). When the transfer frame runs back and forth on the lift frame, the lift frame is motionless and the walking beams respectively move backwards and forwards (movements are strictly horizontal). 提升框架在斜臺(tái)軌上作升降運(yùn)動(dòng)時(shí),平移框架不動(dòng),步進(jìn)梁做上升及下降運(yùn)動(dòng)(嚴(yán)格按垂直方向運(yùn)動(dòng))。 The walking beam mechanism consists of an upper transfer frame which carries the walking beams, and a lower frame which supports the upper frame and runs on inclined ramps. The stepbystep transport through the furnace is achieved by the bined successive actions of the lift and transfer frames. 步進(jìn)梁機(jī)械裝置包括一個(gè)固定爐內(nèi)步進(jìn)梁的上部平移框架,和一個(gè)為平移框架提供支撐和運(yùn)行軌道的下部提升框架,下部提升框架在斜臺(tái)軌上運(yùn)動(dòng)完成提升動(dòng)作。 WALKING BEAM CONVEYANCE SYSTEM步進(jìn)梁輸 送系統(tǒng) Please refer to drawing 17 3027 A 0230 4 P 0001 Under furnace mechanism Assembly 請(qǐng)參見爐底機(jī)械參考裝配圖 17 3027 A 0230 4 P 0001 Function 功能 This unit conveys the product step by step from the charging side of the furnace to the discharging side while the product is being heated. 這套系統(tǒng)將板坯從加熱爐的裝料側(cè)一步一步地輸送到出料側(cè),在這個(gè)過程中,板坯完成加熱。 / D – HANDAN ANNEX 2 Section A / 8 The last forward position of the charge machine is stored in the controller memory for calculation of a new charging cycle. 裝鋼機(jī)最后前進(jìn)到達(dá)的位置被儲(chǔ)存在控制器里,用于計(jì)算新的裝鋼循環(huán)。 The calculated product widths are then used for calculating the remaining forward stroke for positioning in the furnace and stored by the controller for the subsequent product tracking purposes. The machine will then lay down the slab on the furnace skids and move back to its original position. 計(jì)算得到的寬度,用于確定板坯裝入爐內(nèi)合適位置時(shí)裝鋼機(jī)還需要前進(jìn)的行程,并確定后續(xù)板坯的跟蹤位置。 The machine then lifts the slab and moves it forward until the leading edge breaks a photocell looking across the front of furnace. At the same time, the width measurements of the products are made again by counting the pulses emitted by the pulse generator until the moment when the product edges are detected by the photo cell. 然后,裝鋼機(jī)托起板坯并向前移動(dòng),裝料定位光柵檢測到坯料前 沿為止。參見布料圖 .
