摘要： PURPOSE:To reduce occurrence of partial excess so as to prevent occurrence of product other than the ordered one at a product extracting stage. CONSTITUTION:A method of managing the production of sheet steel in a steel work industry, comprises steps 102 to 104 of determining an order configuration in accordance with a size and a continuity of a rot for ordered steel sheet steel products so as to find out one of a small rot order, a repetitive large rot order and a nonrepetitive large rot order, to which the order configuration belongs. Temporary material organization is carried out for the determined rot order, and a workmanship is evaluated for each material organization in view of an original evaluating formula so as to determine a unit weight of a design product.

摘要： PURPOSE:To provide an installation having improved thermal efficiency by using heating rolls for the secondary heating of the installation provided with a quick cooling zone, holding zone, secondary heating zone, overaging zone and secondary cooling zone in succession to a heating zone, soaking zone and slow cooling zone. CONSTITUTION:The continuous annealing installation is provided with the heating zone 1 for heating a steel strip A up to the prescribed temp. above the recrystallization temp., the soaking zone 2 for holding the strip at the temp. of the zone 1, the cooling zone 3 for slow cooling of the strip down to the prescribed temp. for starting the quick cooling, the quick cooling zone 4 for quick cooling of the strip with cooling rolls 5 down to the prescribed quick cooling end temp., the holding zone 6 for holding of the strip at the final cooling temp., the secondary heating zone 7 for heating the strip with heating rolls 8 up to the prescribed aging temp., the overaging zone 9 for holding the strip at the overaging temp. and the secondary cooling zone 10 for cooling down to the ordinary temp. The heating rolls 8 are heretofore not usable owing to the heat resistance of the rolls but in this part the strip is required to be heated in the low temp. part of, for example, 250 400 deg.C and therefore there is no problem of the heat resistance and the thermal efficiency is remarkably improved as compared to other systems.

摘要： PURPOSE:To elevate the produce quality by detecting the plate width of at least one part of rolled stock of the inlet side and outlet side of a rolling mill and by varying the distance between a work roll tapered part and an end edge of a rolled stock according to the deviation with a target value. CONSTITUTION:The feedback control of a plate width to the target plate thickness is performed by changing upper and lower work rolls 1a, 1b simultaneously in reverse direction to the axial part according to the deviation between the plate width detected by a plate width detector 3 and the target plate thickness. Namely, the plate width detected by the detector 3 is inputted into a computing element 4 and converted to a roll gap area from the deviation with the target width. The target shift position of a roll is also calculated with adding the deviation to the actual area which is found from the actual shift position and inputted into a position controller 5. The device 5 then moves symmetrically in the axial direction the rolls 1a, 1b via shifting devices 6a, 6b. Consequently due to good plate width control being enabled, the product quality is elevated.

摘要： PURPOSE:To prevent nonuniform cooling of a steel plate without taking tension into consideration by detecting the temp. distribution of the steel plate in the transverse direction thereof on the outlet side of cooling rolls disposed in a continuous annealing furnace and changing the ejecting rate of gas jet on the inlet side of the cooling rolls. CONSTITUTION:Cooling rolls 2 are disposed in a continuous annealing furnace and the temp. distribution of a steel strip in the transverse direction thereof is detected with a thermometer 4 disposed on the outlet side of the rolls 2 in the stage of winding the steel strip on said rolls and cooling the strip. The ejecting rate of the gas jets from gas jet coolers 1 disposed on the outlet side of the rolls 2 is transversely changed according to the temp. distribution. The temp. difference in the transverse direction is suppressed to about 20 deg.C in the stage of cooling the strip from, for example, 650 deg.C to 400 deg.C by the above-mentioned method, by which the steel strip having no uneven material quality in the transverse direction is obtd.

摘要： PURPOSE:To improve the contact between plural cooling rolls and a steel strip and to prevent the generation of a shape defect in the cooled steel strip by using small-diameter rolls for the plural cooling rolls and disposing the rolls in a semicircular shape having a specific radius in the stage of cooling the steel strip with said cooling rolls. CONSTITUTION:Cooling rolls 1 of an internal water cooling type having a small diameter (d) are disposed in n-pieces in a semicircular shape of a diameter D in the stage of cooling a steel strip which passes the inside of a continuous annealing installation. A steel strip 2 is cooled by passing the same through n-pieces of such cooling rolls 1. The rolls 2 are disposed in such a relation that satisfies the equation [ I ] among D, d, n and therefore the strip is kept free from a shape defect that may arise from the defective contact with the rolls 1. In the equation ( I ), t is the max. thickness of the traveling strip (mm.) and T is the contact time with the rolls 1(min).

摘要： The present invention relates to a method for cooling a steel strip in a continuous-annealing furnace. Conventionally, the steel strip is cooled by a water medium and, thus, oxidation is inevitable. Recently developed roll cooling methods can prevent oxidation but are disadvantageous in that the steel strip is non-uniformly cooled as seen in its short width direction. The present invention attains uniform cooling by means of feedback control, in which the blowing width of the gas-jet cooler (21) is controlled by detecting the sheet temperature distribution with a thermometer (24, 60).

摘要： PURPOSE:To reduce an edge drop of strip and to obtain an excellent shape of product by using a rolling mill having specific taper parts, laterally symmetrically with respect to both upper and lower rolls, at the body ends of said rolls movable in their directions, in rolling a strip. CONSTITUTION:A rolling mill, formed by arranging the 1st taper parts 11, 21 having relatively large projected crown-shaped tapers and the 2nd taper parts 12, 22, adjoining to the 1st taper parts, having small projected crown- shaped tapers or recessed ones, bisymmetrically with respect to rolls 10, 20, is used for rolling. Then rolling, the rolls are symmetrically shifted in their axial directions to set the 2nd taper parts 12, 22 oppositely to the edges of a strip 2. In this way, the edge drop of strip 2 is reduced.
