1、河北聯(lián)合大學(xué)本科生畢業(yè)設(shè)計(jì)摘要根據(jù)設(shè)計(jì)任務(wù)要求，進(jìn)行年產(chǎn)40萬(wàn)噸硬線車間設(shè)計(jì)。設(shè)計(jì)參考眾多國(guó)內(nèi)外先進(jìn)的線材生產(chǎn)廠，由任務(wù)書(shū)產(chǎn)量要求，選擇高速線材生產(chǎn)方式。設(shè)計(jì)內(nèi)容包括建廠經(jīng)濟(jì)依據(jù)、產(chǎn)品大綱分配、原料選擇、出口速度選擇、道次選擇、軋機(jī)比較及選擇、孔型系統(tǒng)設(shè)計(jì)、速度計(jì)算、溫降計(jì)算、力能計(jì)算、軋輥校核、斯太爾摩風(fēng)冷線等輔助設(shè)備選擇等。為保證高速下順利軋制，全線為平立交替布置，軋件無(wú)扭運(yùn)行，盡可能減少事故隱患。粗中軋機(jī)采用高剛度二輥短應(yīng)力線軋機(jī)，預(yù)精軋機(jī)前兩架短應(yīng)力線軋機(jī)，后四架采用懸臂式軋機(jī)，這樣可以
2、安裝高硬度耐磨碳化鎢輥環(huán)，延長(zhǎng)軋輥孔型壽命，保證最終產(chǎn)品精度。精軋機(jī)組采用10架方案，皆為超重V型懸臂成組傳動(dòng)軋機(jī)，出口安裝4架減定徑機(jī)，保證軋制速度高并且尺寸精確穩(wěn)定。生產(chǎn)線預(yù)精軋后采用了長(zhǎng)段高強(qiáng)度水冷，保證進(jìn)精軋軋件溫度較低。精軋后的穿水冷卻，保證吐絲機(jī)吐絲溫度。產(chǎn)品按照德國(guó)DIN標(biāo)準(zhǔn)A級(jí)生產(chǎn)（Φ6.5±0.1㎜）。車間工藝與設(shè)備選擇能夠高精度生產(chǎn)Φ6.5硬線。關(guān)鍵詞：硬線；短應(yīng)線軋機(jī)；平立交替；超重V型無(wú)扭軋機(jī)；控制冷卻I河北聯(lián)合大學(xué)本科生畢業(yè)設(shè)計(jì)ABSTRACTThistaskistod
