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。 -
A sicp reinforced al - cu alloy and al matrix composites are fabricated by a new method - electromagnetic centrifugal casting, the effects of rotational rate for centrifugation, magnetic density, particle size and matrix on the distribution of particles and microstructure of matrix are studied
首次利用電磁離心凝固方法制備sic _ p al基和sic _ p al - cu基復合材料，研究了離心轉速、顆粒尺寸、磁場和基體對顆粒分佈以及對復合材料基體組織的影響。 -
The particle - enriched zone moves outwards as the rotational rate increases. by employing steady dc magnetic field to the conventional centrifugal casting method, the distribution of particles is changed. the most uniform distribution is obtained when the magnetic density is 0. 15t
通過向常規的離心鑄造中引入穩恆直流電磁場，基體中的顆粒分佈得到改善，磁感應強度為0 . 15t時，顆粒的分佈最為均勻，磁感應強度過大時，磁場將會引起基體組織粗化。
