Abstract: A roll stand for a pair of work rolls includes a housing with two side walls arranged on a common base plate. A cube-shaped receiving space which is open toward the top and toward two sides and is provided with guide surfaces for an insertable roll cassette is formed between the side walls. The insertable roll cassette of the roll stand includes two side plates which extend parallel to each other and are spaced at a distance from each other. The outer sides of the side plates are guided by the guide surfaces of the side walls. The side plates form guide means for two pairs of chocks which receive the work rolls with the bearings of the rolls. A pair each of interacting chocks are connected by means of adjusting spindles which absorb rolling forces, wherein the distance between chocks is adjustable so as to produce pre-adjustable passes. The adjusting spindles include adjusting collars and the side plates have adjusting pieces which are compatible with the adjusting collars.
