Design feature of roller guides for wire rod block

The design of roller guides for high speed applications, such as
in wire rod mills, requires certain characteristics in order to fulfil
the high demands in high speed rolling.

This in respect of precise setting means close tolerance finish of
all parts. Much attention has to be paid to the bearing arrangement in
order to withstand the extreme high-speed requirements.

Morgårdshammar have two different lines of high-speed roller guides that stand up to
these high demands. The since long time well proven 800-series and the new single
point adjusted 1000-series type. The 1000-series is available both as two and four roller
type.

The two different lines are both well balanced and stand up superb to the required
specifications.

The Morgårdshammar roller guides are used today in applications up to 110 m/s
continuos rolling finishing speed but are designed for speeds up to 140 m/s.

The design of the Morgårdshammar high speed roller guides where based on the
following factors:

Simple design and easy adjustment.
Minimised and standardised components.
Stainless steel material in order to withstand the severe environment in a WRB
The roller bearings must permit quick acceleration to very high rolling speeds.
The distance between guide roller and work rolls must be as short as possible
(in cases where no nosepiece is used).
The entry guide halves should be flushed with cooling water in order to keep them
free of scale.
