Transport roller for the steel industry

The invention relates to a transport roller for the steel industry, consisting of a metal core and an elastic cover.

In steelworks, sheet metal sheets of various thicknesses are used for a wide variety of uses transported over tracks equipped with rollers. It is essential here that the coefficients of friction of such rollers ensure proper transport and proper transport Ensure guidance of the sheet metal tracks.

Due to irregularities, especially in the belt edge, the roles are heavily stressed, so that it It is necessary to use highly stressable materials for the production of the rolls or of the roll covers. They are roll covers known from plastic or rubber, but they wear out quickly under high stress. Through this disruptions are caused in the production process, which can lead to a standstill of the entire system. There has therefore been a move to use rollers made of steel or with a steel coating for transport routes. The steel rollers ensure that the sheet metal webs are transported properly, but they also cause a problem Steel rollers equipped plant an unbearably high noise level.

According to the invention a transport roller for the steel industry is now proposed, which has a high durability, is resistant to mechanical damage. "And causes a great reduction in noise. The transport roller consists of a metal core and an elastic cover and is characterized in that the elastic cover consists of a large number of axially drawn nonwoven disks pressed onto one another.

Due to the structure of the roll cover from disks, damage, if it occurs at all, has an effect do not have a detrimental effect on the function of the transport system, because they do not lead to failure of the role. at Plastic or rubber coatings, on the other hand, often cause disruptions in the production process due to failure single. Roles can lead to a standstill of the system.

The transport roller according to the invention lowers the very high noise level previously thought to be unavoidable, which compared to steel rollers still shows no more than a third of the values measured so far. The nonwoven rolls have excellent coefficients of friction and are insensitive to contamination on their surface such as oil. This penetrates the nonwoven and is thus removed from the surface, which itself is not influenced. At the same time, the friction effect is reduced. With the usually The steel or plastic or rubber rollers used change impurities such as oil and grease Roller surface and cause a decrease in the coefficient of friction.

The properties of the roll cover can be made more acid and / or alkali resistant through a suitable choice Pipes and binders vary widely. Furthermore, the pore volume and strength of the nonwovens can be determined set using appropriate needle techniques. The hardness of the coating and thus the role can be through Increase or decrease in the pressure when pressing the discs together and by their number when Vary the structure of the roller toe cover and thus adapt it to the intended use.
