根據(jù)以往經(jīng)驗和普線軋機精軋離心輥的技術(shù)要求，經(jīng)反復研究和討論認為選用供應精軋鋼管中合金冷硬離心軋輥可以滿足技術(shù)要求。離心輥外層采用中合金冷硬鑄鐵，芯部采用高強度球鐵。中合金冷硬離心軋輥輥身工作層硬度高，工作層為只含有少量石墨的純白口層，軋輥的耐磨性特別好。 </p> <p> <br /> 高質(zhì)量精軋鋼管的概念：以節(jié)約鋼材、提高鋼筋屈服強度為目的，以超過屈服強度而又小于極限強度的拉應力拉伸鋼筋，使其產(chǎn)生塑性變形的做法叫鋼筋冷拉。 </p> <p> 精軋鋼管產(chǎn)品廣泛應用于：機械設(shè)備：木工機械、陶瓷機械、造紙機械、玻璃機械、食品機械、建筑機械、塑料機械、紡織機械、千斤頂、液壓機等;電器產(chǎn)品部件：電機軸、風扇軸、縫紉機軸等;家具：特別是出口金屬家具，如茶幾、椅子、戶外家具。 </p> <p> 精軋螺紋鋼管的主要生產(chǎn)流程管坯及坯加熱、管坯的穿孔、鋼管的延伸、鋼管的軋制、鋼管定徑與減徑、鋼管的冷卻和精整或者可以說是鋼胚的加熱、穿孔、熱扎、酸洗、冷拔、碳燒、切頭、噴標、包裝、成品冷拉鋼管是在常溫條件下，以超過原來鋼筋屈服點強度的拉應力，強行拉伸鋼筋，使鋼筋產(chǎn)生塑性變形以達到提高鋼筋屈服點強度和節(jié)約鋼材。 </p></div><p><img

真空退火優(yōu)質(zhì)彈簧鋼、工具鋼、精密鋼管的絲材，不銹鋼制品及鈦合金材，作光亮退火均可采用真空處理。退火溫度愈低，則要求真空度愈高。為防止鉻的蒸發(fā)及加速熱傳導，一般采用載氣加熱(保溫)法，并注意對不銹鋼和鈦合金不宜用氮而應采用氬氣。<br /> 過程 </p> <p> 真空淬火真空淬火爐按冷卻方法分為油淬和氣淬兩類，按工位數(shù)分為單室式和雙室式，904山\畏嘲均屬周期式作業(yè)爐。真空油淬爐都是雙室的，后室置電加熱元件，前室的下方置油槽。工件完成加熱、保溫后移入前室，關(guān)閉中門后向前室充入惰性氣至大約2．66%26times;lO ～1．01%26times;10 Pa(200～760mm汞柱)，入油。油淬易引起工件表面變質(zhì)。由于表面活性大，在短暫的高溫油膜作用下即可發(fā)生顯著薄層滲碳，此外，碳黑和油在表面的粘附對簡化熱處理流程很不利。真空淬火技術(shù)的發(fā)展主要在于研制性能優(yōu)良、工位單一的氣冷淬火爐。前述雙室式爐亦可用于氣淬(在前室噴氣冷卻)，但雙工位式的操作使大批量裝爐的生產(chǎn)發(fā)生困難，也易在高溫移動中引起工件變形或改變工件方位增加淬火變形。單一工位的氣冷淬火爐是在加熱保溫完成后在加熱室內(nèi)噴氣冷卻。氣冷的冷速不如油冷快，也低于傳統(tǒng)淬火法中的熔鹽等溫、分級淬火。因而，不斷提高噴冷室壓力，增大流量，以及采用摩爾質(zhì)量比氮和氬小的惰性氣體氦和氫，是當今真空淬火技術(shù)發(fā)展的主流。70年代后期將氮氣噴冷的壓力從(1～2)%26times;10Pa提高到(5～6)%26times;10Pa，使冷卻能力接近于常壓下的油冷。80年代中期出現(xiàn)超高壓氣淬，用(10～20)%26times;10Pa的氦，冷卻能力等于或略高于油淬，已進入工業(yè)實用。90年代初采用40%26times;10Pa的氫氣，接近水淬的冷卻能力，尚處于起步階段。工業(yè)發(fā)達已進展到以高壓(5～6)%26times;10。Pa氣淬為主體，而中國產(chǎn)氣淬一些金屬的蒸氣壓(理論值)與溫度的關(guān)系則尚處于一般加壓氣淬(2%26times;10Pa)型階段。

不銹鋼管是一種中空的長條鋼材，大量用作輸送流體的管道，如石油、天燃氣、水、煤氣、蒸氣等，另外，在搞彎、抗扭強度相同時，重量較輕，所以也廣泛用于制造機械零件和工程結(jié)構(gòu)。也常用作生產(chǎn)各種常規(guī)武器、槍管、炮彈等。 </p> <p> <br /> 分類 </p> <p>  </p> <p> 鋼管分無縫鋼管和焊接鋼管（有縫管）兩大類。按斷面形狀又可分為圓管和異形管，廣泛應用的是圓形鋼管，但也有一些方形、矩形、半圓形、六角形、等邊三角形、八角形等異 </p> <p> 形鋼管。<br /> 對于承受流體壓力的鋼管都要進行液壓試驗來檢驗其耐壓能力和質(zhì)量，在規(guī)定的壓力下不發(fā)生泄漏、浸濕或膨脹為合格，有些鋼管還要根據(jù)標準或需方要求進行卷邊試驗、擴口試驗、壓扁試驗等。 </p> <p>
