1、武漢科技大學本科畢業(yè)設(shè)計摘要軋鋼生產(chǎn)已經(jīng)成為冶金生產(chǎn)行業(yè)中把鋼坯軋制成鋼材的重要生產(chǎn)環(huán)節(jié),具有產(chǎn)量大、品種齊全,生產(chǎn)過程機械化自動化程度高等許多優(yōu)點,是滿足國民生產(chǎn)需要的重要技術(shù)。而矯直技術(shù)是提高板帶鋼產(chǎn)品表面質(zhì)量和平坦度的重要環(huán)節(jié)。矯直機在冶金工業(yè)種用途非常廣泛,它是冶金工業(yè)生產(chǎn)中常用的矯直設(shè)備。隨著科學的發(fā)展軋鋼生產(chǎn)行業(yè)與傳統(tǒng)機械業(yè)進一步緊密的結(jié)合在一起。利用軋鋼生產(chǎn)技術(shù),提高軋制產(chǎn)品的質(zhì)量,減少軋制生產(chǎn)的時間,提高成品率,降低生產(chǎn)成本和提高材料利用率已經(jīng)成為軋鋼機械設(shè)計的主要目標。在現(xiàn)代化程度較高的連鑄生產(chǎn)線中,連鑄坯的矯直設(shè)備是必不可少的;在型鋼、鋼板、鋼管等軋鋼廠的精整車間,
2、矯直機則更是必備的設(shè)備之一。平直度是評價金屬板帶質(zhì)量的重要指標之一,隨著用戶對板帶質(zhì)量要求的不斷提高,板帶平直度的控制和改善顯得日益重要。板材矯直機是消除板材平直度缺陷,改善板形的關(guān)鍵設(shè)備。經(jīng)過現(xiàn)場實習,本文是依據(jù)輥式板帶矯直機的生產(chǎn)過程和工作原理,按照設(shè)計要求,首先計算薄板夾送矯直機組的矯直機結(jié)構(gòu)參數(shù)和力能參數(shù),然后設(shè)計計算夾送輥的基本結(jié)構(gòu)參數(shù)和力能參數(shù),再根據(jù)夾送輥的受力和夾送輥軸承座的受力情況來設(shè)計計算夾送輥彈簧調(diào)整系統(tǒng)的主要零部件的尺寸大小,并對其進行強度校核,最終完成整個設(shè)計過程。關(guān)鍵詞:輥式矯直機;力能參數(shù);結(jié)構(gòu)參數(shù);夾送輥;調(diào)整系統(tǒng)。25武漢科技大學本科畢業(yè)設(shè)計Abstr
