FIELD: machine building. ^ SUBSTANCE: invention is intended for increasing the production and operating efficiency of warmth-keeping plants. Section with heat-reflecting surface B wide and L long includes load-carrying housing with drive of its movement to/from the roller bed having pitch of rollers lr; on the housing there fixed is a number of equal cassettes provided with a set of pipes tightened with pins and having the pipe length l and the set width b; at that, longitudinal axes of pipes in the set are located in the direction of the section length and heat-reflecting surfaces of cassettes form heat-reflecting surface of the section. Simplification of the manufacture of the device and improvement of the manufacturing accuracy of its component parts, reduction of outages of the roller bed during erection and removal of cassettes is provided owing to the fact that the section has the following number of ratios of B, L, b, l and lr: in cassette is equal or , or , or , length l in the cassette is equal or , or , or , or , or , or , or ; at that, and values are whole numbers. ^ EFFECT: there is proposed section (module) of warmth-keeping plant for screening the upper surface of the roll on roller bed of broad-strip hot rolling mill. ^ 10 dwg, 3 tbl |
