Centrifuge casting of roll collar for wire preliminary finishing mill
線材預精軋機用輥環的離心鑄造 -
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。 -
