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。
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.
选择不同的公差在“弧齿槽宽”和“弧齿厚”中应用。
The selections differ only in the tolerance as applied to space width and tooth thickness.
