Typical products 30CrMo, a diameter of 16 bar. Review the entire manual, including, text and thematic three parts. Described in section bars review the basic knowledge and the status bar production at home and abroad. The second part is the body part (from chapter to chapter IX) Body of the text shows that the whole design of the overall program, including products, programs, processes, production of program development, the metal balance of the development, production equipment selection, process parameter calculation, calculation of pass, pass design, rolling force and energy parameters Check, check bite angle capacity, annual production levels, but also the environmental protection measures. Pass also drawn maps and workshop plans. Special section briefly describes the features on the tool and die steel and production. Keywords: Bar。 process design。 pass design。 check。 Tool Steel 遼寧科技大學(xué)本科生畢業(yè)設(shè)計(jì)（論文） 第 III 頁(yè) 1. 綜述 ............................................................................................................ 6 棒材的分類(lèi) ................................................................................................................ 6 棒材的軋機(jī)分布及生產(chǎn)工藝 .................................................................................... 7 棒材軋機(jī)布置： .............................................................................................. 7 棒材的生產(chǎn)工藝 .............................................................................................. 7 棒線材生產(chǎn)技術(shù)的發(fā)展與進(jìn)步 ................................................................................ 9 注重改進(jìn)軋前工序 .......................................................................................... 9 加熱爐技術(shù)進(jìn)步 .............................................................................................. 9 熱送熱裝 .......................................................................................................... 9 感應(yīng)加熱 ........................................................................................................ 10 無(wú)頭軋制工藝 ................................................................................................ 10 棒線材生產(chǎn)的定徑減徑機(jī)組 ........................................................................ 11 控制冷卻工藝 ................................................................................................ 12 多種機(jī)型的運(yùn)用 ............................................................................................ 12 我國(guó)棒線材發(fā)展現(xiàn)狀 .............................................................................................. 13 20 年前我國(guó)棒線材生產(chǎn)狀況 ....................................................................... 13 20 年來(lái)型鋼生產(chǎn)的技術(shù)進(jìn)步 ....................................................................... 14 我國(guó)棒線材生產(chǎn)現(xiàn)狀 .................................................................................... 14 國(guó)外棒線材的發(fā)展現(xiàn)狀 .......................................................................................... 15 特殊鋼棒線材的發(fā)展 .................................................................................... 15 支撐開(kāi)發(fā)高級(jí)棒線材的技術(shù)分析 ................................................................ 16 我國(guó)線棒材健康發(fā)展應(yīng)采取的對(duì)策 ...................................................................... 17 改造或淘汰落后的生產(chǎn)線 ............................................................................ 17 調(diào)整品種結(jié)構(gòu) ,開(kāi)發(fā)新產(chǎn)品 ........................................................................... 17 跟蹤世界前沿 ,積極引進(jìn)和消化國(guó)外先進(jìn)技術(shù) ........................................... 18 2 產(chǎn)品方案的確定與編制金屬平衡表 ......................................................... 19 產(chǎn)品方案的確定 ...................................................................................................... 19 確定金屬平衡表 ................................................................................................. 20 確定計(jì)算產(chǎn)品的成品率 ................................................................................ 20 計(jì)算產(chǎn)品的選擇 ............................................................................................ 21 計(jì)算產(chǎn)品的技術(shù)標(biāo)準(zhǔn) .................................................................................... 21 生產(chǎn)工藝流程的制訂 .............................................................................................. 22 制訂生產(chǎn)工藝流程 ........................................................................................ 22 工藝流程簡(jiǎn)介 ................................................................................................ 23 3 設(shè)備選擇 ................................................................................................... 25 加熱爐 ...................................................................................................................... 25 爐型選擇 ........................................................................................................ 25 加熱爐性能參數(shù) ............................................................................................ 26 主軋機(jī) ...................................................................................................................... 26 軋機(jī)的組成 .................................................................................
