摘要： 본발명은수평원심주조법에의한압연용슬리브롤의제조방법에관한것이다. 구체적으로는몰드의회전속도를서서히올리는워밍업단계(S1)와, 상기워밍업단계후에외층재를투입하여제1회전속도로일정시간몰드를회전시켜외층을형성하는외층형성단계(S2)와; 상기외층형성단계후 내층재를투입하여제2회전속도로일정시간몰드를회전시킨다음, 제3회전속도로일정시간몰드를회전시킨후, 제4회전속도로일정시간몰드를회전시키는 3단계로회전시켜내층을형성하는내층형성단계(S3)로이루어진다. 이와같은제조방법에의하면, 진동이낮으면서용탕낙하현상(Raining)과슬립현상및 층박리현상이없어외층의표면박리현상과내층의불균일응고현상이일어나지않으므로높은품질의압연용슬리브롤을제조할수 있다는효과가있다.

摘要： PURPOSE: A method for manufacturing a rolling sleeve roll using a horizontal type centrifugal casting method is provided to manufacture a rolling sleeve with high quality roll by preventing non-uniform coagulation and exfoliation. CONSTITUTION: A method for manufacturing a rolling sleeve roll using a horizontal type centrifugal casting method is as follows. The rotation speed of a mold is gradually increased(S1). An outer layer material is put into the mold, and an outer layer is formed by rotating the mold with first rotation speed. An inner layer material is put into the mold, and the mold is rotated with second rotation speed. The mold is rotated with third rotation speed, and then an inner layer is formed by rotating the mold with fourth rotation speed.
摘要翻译：目的：提供一种使用卧式离心铸造方法制造滚动套筒辊的方法，通过防止不均匀的凝结和剥落来制造具有高质量辊的滚动套筒。构成：使用卧式离心铸造法制造滚动套筒辊的方法如下。模具的转速逐渐增加（S1）。将外层材料放入模具中，通过以第一转速旋转模具形成外层。将内层材料放入模具中，并且模具以第二转速旋转。模具以第三转速旋转，然后通过以第四转速旋转模具形成内层。
