2 roll wiper system in sendzimir mill

A wiper for one of the rolls of a rolling mill including spaced housings, said wiper comprising a generally flat plate extending along the roll and substantially co-extensive therewith, the side of the plate adjacent to the roll being adapted to engage the roll edgewise, a pivot pin on each housing, spring levers each having one end thereof ...

This roll set up allows extremely high forces to be exerted through the work roll and yet keep the work roll from extreme flexing. The take-up roll on the Sendzimir mill also exerts a tension on the coil as it comes through the mill. The combination of high pressure and tension makes the mill capable of rolling material thin and flat.

The calculation of force for a roll system has significant effects on cold rolled thin strip gauge adjustment of a 20-high Sendzimir mill. According to the rolling parameters and rolling plans of a ZR-22BS-42 Sendzimir mill in a silicon steel factory, the contact force and the resultant force of each roll in the roll system were calculated both in the static state and in the rolling state ...

Sendzimir Mill Features . The Sendzimir mill arch is integrally cast and pre-stressed, and a circular arc track is provided in the arch to secure the backup roll. All the intermediate rolls are fixed on the arch by the suspension hydraulic cylinders on the transmission side and the operation side, and the suspension force is set according to the weight of the roller body.

Sendzimir Mill Rolling to Final Gauge • For thin gauge, specialized rolling mills are used to achieve uniform cross-strip thickness and flawless surfaces on material down to 0.001" (0.025 mm). • Arnold does, incidentally, roll other alloys to as little as 85 millionths of an inch (0.000085") on Sendzimir mills.

Fig 2 Typical 4-high stands showing various details. Pre-stressed mill stand – In a conventional rolling mill, the roller separating force which arises when the work piece bar is passed through the rolls is transferred through the backup rolls and their bearings to the mill house. In a pre-stressed mill stand, the two backup rolls are connected to each other by an element, pre-stressed to a ...

Sendzimir rolling mill is basically a single stand reversible arrangement, with great flexibility and a wide range of products. However, there are very few Sendzimir mills with a continuous arrangement. For example, Japan Sendzimir Corporation designed a set of 1270 mm four-stand full-continuous 20-roll Sendzimir mill in 1969.

A Sendzimir rolling mill (ZRM) uses a work roll with a small diameter to roll high strength steel. On the other hand, the work roll is often bent because its diameter is very small compared with its length. From roll bending, a complex wave shape appears in the rolled steel plates.
