摘要： The invention relates to adjusting tensions between the mills of continuos hot rolling mill trains. The measurement of rolling parameters and adjustment of the torque of motors of said mills are carried out successively by groups of three. In the first adjustment stage, during the time between the moment when a work piece enters the first mill and the moment when it enters the second mill, a signal storing the value of a static load torque and the speed mode of the motors of the first mill is formed. In the second stage, during the time between the moment when the work piece enters the second mill and the moment when it enters the third mill, a signal indicating a change in the speed mode of the motors of the first mill is formed if said speed mode is different from the reference value, i.e. the minimum torque of the first stage. In the third stage, from the moment when the work piece enters the third mill, the ratio between the torque of the stored static load and the current value of the torque of the motors of the third mill is calculated, the signal of the difference therebetween being formed and the continuous adjustment of the speed mode of the first mill being carried out. In the fourth stage, when the work piece exits from the first mill, adjustment of motors of the first and second mills is interrupted. The signal formed in the third stage is stored.

摘要： A multi-directional warm-rolling method for manufacturing a superfine grain steel material with a superfine crystal grain structure of 3 mum or smaller in average grain size. When rolling of two passes or more is performed for a steel material in the rolling temperature range of 350 to 800˚C, a rolling by an oval shape hole die and a rolling by the other shape hole die are performed at least one time so that a large amount of strain can be introduced into the material by a simple means with less section reduction rate and less number of passes. Steel materials having the superfine crystal grain structure and excellent strength and ductility can be manufactured by this method.

摘要： A method of sizing-rolling performed by installing three units or more of 4-roll rolling mills in series with each other, comprising the steps of setting, in a first pass, a center angle theta 1 of the complete round forming part of a rolling roll at less than 15 DEG , setting, in the third pass, the center angle theta 3 at 45 DEG or more and, in the second pass (B), the center angle theta 2 at 30 DEG or more, forming the groove of each rolling roll so that a relief part is made tangential to an arc formed with the complete round forming part, installing, in the second pass, a roller guide with four guide rollers on the inlet side so as to hold and guide the free surface of a rolled material by the guide roller, and making equal, in the first pass, the angle alpha of the V-groove in the guide roller to the angle (90 DEG + theta 1) formed by the straight lines forming the relief part of the rolling rolls adjacent to each other, whereby an excellent surface properties can be obtained while a wide size free area is assured even when a wire of 7.0 mm or less in diameter is used.

摘要： The invention relates to a method for producing rods, bar stock or seamless tubes on a rolling stand for rolling hot metal material. Said rolling stand optionally comprises, when seen in the direction of rolling, a piercing-crossrolling mill, a multiple-stand stretch-rolling mill as the main stretching stage (4), a drawing mill (6), a finishing mill (10) and a rod rolling block (15) and devices, mounted upstream, intermediately or downstream thereof, such as a preheating furnace and a reheating furnace (11), roller tables (14) and a cooling bed (13). According to the inventive method, in the main stretching stage (4), a three-roller continuous rolling mill (3) is used both for rolling tubes and for massive rolling for producing bar stock, rods or the like. For massive rolling, the mandrel bar used for tube milling is brought out of the operative position and the provided bar stock rolls calibrated for a larger diameter reduction than used for tube milling are replaced by rolls calibrated for tube milling. A rolling mill suitable for carrying out the inventive method has, in the main stretching stage (4), a multi-stand three-roller continuous rolling mill (3) adapted to receive bar stock rolls or tube rolls and a device for removing the mandrel bar.
