    • The present invention is to provide a rolling mil roll including a rolling mill ring and a metal base in which a tensile stress applied to the rolling mill ring located along the outer circumferential face side is reduced; and then cracks thereon are prevented from occurring. The rolling mill roll 10 includes: the rolling mill roll 11 made of cemented carbide having rolling sections 13 on its outer circumferential face 11a; and the metal base 12 located on the inner circumferential face of the rolling mill roll 11. The circumferential interface 14, where the rolling mill ring 11 and the metal base 12 face each other, is fixed radially around its axis L by a contact pressure derived from a fitting section, and also is bound with an adhesive agent M.

    • A caliber roll for rolling consisting of a roll main body having a caliber on the outer circumference and provided with a shaft hole penetrating in the axial direction, and a roll shaft inserted into the shaft hole of the roll main body, in which a compressive stress in the widthwise direction of the roll main body is applied to the bottom of the caliber. This compressive stress is applied by forming either the inner circumference of the roll main body or the circumference of the roll shaft in a taper, and shrinkage-fitting or cold-fitting the roll main body and the roll shaft, or by pressing the both end faces in the widthwise direction of the roll main body by means of a pressing jig fixed to the roll shaft. In addition, a recess gap is provided in either one or both of the inner circumference in the middle of the widthwise direction of the roll main body and the corresponding circumference of the roll shaft. The roll main body is composed of an iron-based alloy including, by weight, C: 0.75 to 1.75%, Si: 3.0% or less Mn: 2.0% or less, P: 0.30% or less, S: 0.030% or less, Cr: 5.0 to 13.00%, Mo: 0.80 to 5.0%, and V: 0.1 to 0.5%, in which the entire hardness is adjusted to H.sub.R C 52 to 56, and the metal flow is in the axial direction.
    • 一种用于轧制的口径辊,其由在外圆周上具有口径的辊主体和沿轴向贯穿的轴孔组成,以及插入到辊主体的轴孔中的辊轴,其中压缩应力 在辊主体的宽度方向上施加到口径的底部。 该压缩应力通过将辊主体的内周或辊轴的圆周成锥形来进行,并且对辊主体和辊轴进行收缩配合或冷接,或者通过将两端 通过固定在辊轴上的按压夹具在卷筒主体的宽度方向上面对。 此外,在辊主体的宽度方向的中央的内圆周和辊轴的相应圆周之间的一个或两个中设置有凹部间隙。 辊主体由以铁素体为基准的铁基合金构成:C:0.75〜1.75%,Si:3.0%以下Mn:2.0%以下,P:0.30%以下,S:0.030%以下 ,Cr:5.0〜13.00%,Mo:0.80〜5.0%,V:0.1〜0.5%,其中,将整个硬度调整为HRC 52〜56,金属流在轴向。
