摘要:步進式加熱爐用于滿足鋼鐵公司軋鋼廠線材生產工藝的要求,根據線材軋鋼廠生產和工藝要求,鋼坯將被送進在步進式加熱爐內經過加熱,并且達到軋制溫度要求。常見的步進機構型式可以分為直接頂起式,斜塊滑輪式,偏心輪式。 本文選用的是液壓雙缸步進式加熱爐,使用液壓傳動機構運行穩(wěn)定,結構簡單,運行速度的控制比較準確,占地面積小,設備質量小。本文首先是對步進式加熱爐進行了方案論證及最終方案的確定,然后對結構設計,強度驗算,液壓系統(tǒng)的確定演算四個方面進行了詳細的說明,以及制造安裝以及維護過程中應該注意的問題進行了介紹。 關鍵詞:步進式加熱爐 步進液壓系統(tǒng) 爐底機械
ABSTRACT:Reheating furnace wire rod rolling mill for steel companies to meet the requirements of the production process, according to wire rod rolling mills and process requirements, will be sent to the billet reheating furnace is heated, and meet the rolling temperature requirements. Common types can be divided into direct stepping institutions from the top, inclined block pulley, eccentric wheel. This selection of the hydraulic cylinder reheating furnace, using a hydraulic actuator stable operation, simple structure, more accurate control of speed, small footprint, the quality of equipment smaller. This paper is a reheating furnace and demonstration program conducted to determine the final plan, and then the structural design, strength checking, the hydraulic system to determine calculus four aspects of the detailed description, as well as manufacturing, installation, and maintenance process should pay attention issues were introduced Keywords: Reheating furnace; Stepping hydraulic system;Bottom machinery
步進式加熱爐的爐底大概又升降機構,平移機構,步進液壓系統(tǒng)等主要零部件構成的,隨著技術的發(fā)展,加熱爐的爐底液壓系統(tǒng)新的技術改革,加熱爐液壓系統(tǒng)具有的優(yōu)點: 系統(tǒng)采用“ 恒壓變量泵, 可根據系統(tǒng)需要自動給出輸出流量, 泵始終于正常工作狀態(tài)。采用比例閥控制, 做到輕拿輕放功能。同時在改進液壓系統(tǒng)的同時,對其動力源也進行了相應的改善,為解決油缸兩側壓力突變的情況,將提升液壓缸和移動液壓缸均換成對稱式的液壓缸,同時缸的直徑、活塞桿的直徑和所有其它的尺寸均保持不變,則步進梁周期運動的時間與速度要相應的進行調整。因此步進式加熱爐的爐底機械隨著技術的更新,不斷的在各方面都有新的發(fā)展。
