轧辊在制作和运用前的预备工序中会发生剩余应力和热应力。运用时又进一步遭到了各种周期应力的效果，包含有曲折、改变、剪力、接触应力和热应力等。

Residual stresses and thermal stresses will occur in the preparatory process before making and applying rolls. When applied，轧辊生产商， it is further affected by various cyclic stresses， including twists， changes， shear forces， contact stresses and thermal stresses.

冷轧板带轧辊的辊身呈微凸，轧辊，当它受力弯曲时可保证良好扳形；型钢轧机轧辊的辊身上有轧槽，根据型钢轧制工艺要求，安排孔型。钢管轧制中采用斜轧原理轧制的轧辊有圆锥形、腰鼓形或盘形。

The roll body of the cold rolled strip roller is slightly convex. When it is bent by force，轧辊设备生产厂家， it can ensure good shape. There are grooves on the roller body of the section mill roll， and the pass is arranged according to the rolling requirements of section steel. The rollers of skew rolling rolling rolling principle of conical drum or disc.

(1)软辊；肖氏硬度约为30一40，用于开坯机、大型型钢轧机的租轧机等。

(2)半硬辊：肖氏硬度约为40一60，用于大型、中型、小型型钢轧机和钢板轮机的租轧机。

(3)硬面辊：肖氏硬度约为60一85，用于薄板、中板、中型型钢和小型型钢轧机的稿轧机及四辊轧机的支撑辊。

(4)特硬辊le氏硬度约为85—100，用于冷轧机。

(1) soft roll; the hardness of Shaw is about 30 40. It is used for the renting rolling mill of the billet machine and the large steel mill.

(2) semi hard roll: the hardness of the Shaw is about 40 to 60. It is used for the renting rolling mill of large，轧辊报价， medium， small type steel mill and steel plate turbine.

(3) hard roll: Shore hardness of about 60 to 85， for supporting roller mill release sheet， plate， medium and small steel mill and four roller mill.

(4) the hardness of the hard roll Le is about 85 - 100 for cold rolling mill.
