Abstract
The invention covers a supporting roller stand for steel slab strand casting plants, particularly for curved slab strand casting plants with supporting rollers of differential lengths being arranged opposite, in pairs, along the broad sides of the strand profile, subdivided on at least one side over the width of the strand, such supporting rollers being furthermore arranged in groups of differential diameters.
Claims5
Roller stand support apparatus for steel slab strand casting plants and particularly curved slab strand casting plant, comprising
- (a) a plurality of pairs of spaced apart supporting rollers positioned to define a supporting path for a cast strand on each side thereof;
- (b) power means connected to at least some of the supporting rollers for driving said rollers;
- (c) at least some of said plurality of rollers on at least one side of said path being a plurality of coaxially arranged rollers;
- (d) said roller pairs being positioned according to their diameters;
- the improvement characterized by
- (e) said supporting rollers being alternately of larger and smaller diameter along the said path;
- (f) said smaller diameter rollers being said plurality of coaxially arranged rollers;
- (g) the combined length of the supporting surface of each group of coaxially arranged smaller diameter rollers being greater than the length of the supporting surfaces of the said larger diameter rollers, and
- (h) the length of said supporting surfaces of said larger diameter rollers being equal to or less than the width of the strand supported.
