1、畢業(yè)設(shè)計(jì)二十一輥板帶矯直機(jī)的設(shè)計(jì)與校核摘要軋鋼生產(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(jī)械化自動(dòng)化程度高等許多優(yōu)點(diǎn),是滿足國民生產(chǎn)需要的重要技術(shù)。并且隨著科學(xué)的發(fā)展,軋鋼生產(chǎn)行業(yè)與傳統(tǒng)機(jī)械業(yè)進(jìn)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)時(shí)間,提高成材率,降低生產(chǎn)成本和材料的利用率已經(jīng)成為軋鋼機(jī)械設(shè)計(jì)的主要目標(biāo)。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)。本文是依據(jù)板帶矯直機(jī)的生產(chǎn)過程和工作原理,經(jīng)過現(xiàn)場實(shí)習(xí),首先從二十一輥板帶矯直機(jī)的總體
