S Roll of Universal Rolling Mill and Its Main Material
The so-called universal rolling mill is also known as a roll reduction machine. It can be used for rolling section steel,rail,round bars and other metal materials into strips and round products of different specifications. In a general sense, it can also be used for rolling various kinds of metal pipes. The function of the rolling machine is to use rolling force to reduce the thickness of metal materials or to change the profile shape. The product of the rolling machine is strips, round steel and other products of different shapes and specifications.
The S Roll of the universal rolling mill plays an important role in it. It is a kind of cylindrical roller which is gradually reduced in diameter from both ends towards the middle. It is also one of the core components of the rolling mill. The function of the s roll is mainly to roll the material from the roll gap. The S roll passes through the roll gap and is reduced in diameter from both ends towards the middle to form a rolling surface. The material passes through the roll gap, and is extruded and rolled into semifinished products of the required size and shape.
The s roll of the universal rolling mill is usually made of high quality alloy steel with high tungsten and molybdenum content. This kind of alloy steel is with good wear resistance,strength and toughness. The surface of the roll should be quenched and tempered on the surface, so that it has hardness to meet the requirements of use. In order to improve the abrasion resistance of the rolling surface, the surface of the s roll is often subjected to rifle or roller quenching treatment to increase the abrasion resistance and service life of the s rolls.
In addition, the universal rolling mill also uses a lubrication device to lubricate the rolling work, which reduces the friction between the s roll and the material, so as to reduce the damage to the surface of the s roll and prolong its service life.
In summary, the s roll of the infinite rolling mill is a core part of the rolling machine, and its material and quenching treatment have a direct impact on the rolling effect and service life.
