| Abstract: | By adopting the vertical mould and vertical casting program,the riser has been set on the end face of pipe orifice,and the gradient of slope has been set on the wall of valve block for material feeding.Meanwhile,the cutting amount of feeding material and the shaping amount of shape have been decreased.All these measures would improve the utilization ratio of molten steel,and reduce the metal removal rate,and improve the quality of inside and outside wall obviously. |
