冷軋板帶軋輥的輥身呈微凸，當(dāng)它受力彎曲時(shí)可保證良好扳形；型鋼軋機(jī)軋輥的輥身上有軋槽，根據(jù)型鋼軋制工藝要求，安排孔型。鋼管軋制中采用斜軋?jiān)碥堉频能堓佊袌A錐形、腰鼓形或盤形。
The roll body of the cold rolled strip roller is slightly convex. When it is bent by force, 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.
軋輥的品種和制造工藝隨冶金技術(shù)的進(jìn)步和軋鋼設(shè)備的演變而不斷發(fā)展。中世紀(jì)軋制軟的有色金屬時(shí)使用強(qiáng)度低的灰鑄鐵軋輥。18世紀(jì)中葉英國掌握了軋制鋼板用的冷硬鑄鐵軋輥的生產(chǎn)技術(shù)。
The variety and manufacturing process of roll have been developed with the progress of metallurgical technology and the evolution of steel rolling equipment. The use of low strength gray iron rolls in the Middle Ages when rolling soft nonferrous metals. In the middle of the eighteenth Century, Britain mastered the production technology of cold cast iron rolls used for rolling steel plates.
軋輥具有粘著力，優(yōu)異的抗壓強(qiáng)度、耐磨性和抗腐蝕性等歸納功用，選用高分子復(fù)合材料在傳動(dòng)部位磨損規(guī)范相對(duì)較小的狀況下可以現(xiàn)場免拆開修正。
The roller has super strong adhesive force, excellent compressive strength, wear resistance and corrosion resistance, and so on. The polymer material can be free from dismantling in the condition that the wear standard of the transmission part is relatively small.
軋輥在制作和運(yùn)用前的預(yù)備工序中會(huì)發(fā)生剩余應(yīng)力和熱應(yīng)力。運(yùn)用時(shí)又進(jìn)一步遭到了各種周期應(yīng)力的效果,包含有曲折、改變、剪力、接觸應(yīng)力和熱應(yīng)力等。
Residual stresses and thermal stresses will occur in the preparatory process before making and applying rolls. When applied, it is further affected by various cyclic stresses, including twists, changes, shear forces, contact stresses and thermal stresses.
