cast steel roll
解釋
鑄鋼軋輥-
Above all, alloy ductile cast iron is generally selected as the material of edger roll and its durability is better than high carbon semi - steel
綜上所述，國外型鋼軋邊輥材質一般選用合金球墨鑄鐵軋輥，所以其耐磨性也相應地優于高碳半鋼。 -
The composite roll of high speed steel has the synthetical life of over ten times more than traditional high cr cast iron roll. now the research and production of the high speed steel for roll are very drastic. in this thesis, the microstructure, heat treatment and performance of high speed steel fe - 2 % c - 4 % v - 4 % mo - 5 % cr - x % w ( wt ) are studied systematically by using metallograph, method of lattice, xrd, sem, eds and hardness
本文利用金相法（包括黑白金相和彩色金相） 、 x射線衍射（ xrd ） 、掃描電子顯微鏡（ sem ） 、能譜（ eds ）及洛氏硬度分析儀等手段，對復合軋輥用高速鋼fe - 2 c - 4 v - 4 mo - 5 cr - x w （其它部分如未作特殊註明均為質量分數）合金系的顯微組織、熱處理工藝及性能進行了系統地分析。 -
The effect of compound casting technology and compound modification on the properties of high speed steel roll collar was studied. the results showed that compound high speed steel roll collar with high and even hardness and good bond between outer and inner layers could be gained when the modified colbalt free high speed steel in outer layer and nodular iron inner layer in connection with appropriate rotational speed of centrifugal machine, pertinent pouring interval between two kinds of the melt and moderate pouring temperature as well as surface induction heat treatment were chosen. it is indicated in industrial use that the service life of compound roll collar is higher by 5 times than that of high chromium cast iron collar
研究了離心復合鑄造工藝和復合變質處理對高速鋼輥環性能的影響，結果表明，選用變質高碳無鈷高速鋼作外層，用球鐵作內層，選擇合適的離心機轉速、兩種金屬熔液澆注間隔時間和澆注溫度，結合採用表面感應熱處理工藝，可獲得硬度高、均勻性好、內外層結合良好的高速鋼復合輥環，用於工業生產其使用壽命比高鉻鑄鐵輥環提高5倍以上。 -
During the recent years the breakthrough of manufacturing the new type of composite roll has been made. it is possible for the composite roll of high cr cast iron widely used at present to be replaced by the composite roll of high speed steel ( hss ) in the ten years
近年來，將高速鋼用於製造新一代復合軋輥方面取得了突破性進展，高速鋼復合軋輥的綜合使用壽命可以比傳統用高鉻鑄鐵軋輥提高數倍以上，目前被廣泛採用的高鉻鑄鐵復合軋輥，有可能在十年之內被高速鋼復合軋輥取代。 -
This study deals with the influence of rolling to strengthen the fatigue resistance nodular cast iron is less cost and easyer machining than steel, the fatigue resistance of crankshafts can be strengthen by useing deep rolling on the journals that be applied in the diesel instead of steel crankshaft. the study and information are limit in the literature about the roll internationally
國內對球鐵曲軸強化工藝研究尚且不足，球鐵曲軸經過滾壓復合強化，應用於中重型車用柴油機的研究是目前國內曲軸強化研究的課題之一。針對這種情況，本文中對某六缸柴油機球鐵曲軸滾壓強化過程進行分析、試驗和研究。
