The result show that, the as-cast casting can completely meet the specification of Cummins standard about ferrite ductile iron after omitting annealing by high volume production provement.
经批量生产验证，取消了退火，铸态完全达到了康明斯标准规定的铁素体球铁的要求。

Because the high temperature strength of the ferrite stainless steel is low, the breadth of the slab made from the vertical-arc continuous casting machine do not reach tolerance.
铁素体不锈钢由于高温强度低，直弧型连铸机生产的板坯宽度尺寸难以满足公差要求。

The magnetic properties of the slip casting shaped hard ferrite strongly depend on the original slurry granularity.
