本発明はループカーを有する鋼帯の連続処理膜イイ１１
における鋼帯の張力制御方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a continuous treatment membrane for steel strips having a loop car.
The present invention relates to a method for controlling the tension of a steel strip.

る。The continuous processing equipment for steel '4'+F is divided into three parts: a central part for pickling or annealing, an inlet part for receiving coils, and an outlet part for taking out coils. In the processing tank in the center, it is necessary to keep the tension of the copper strip constant in order to stabilize the threading process, but on the entry side, the copper strips are inserted one after another so that there are no breaks in the strip. The copper strip is welded and cut into predetermined lengths on the exit side, so a loop car is installed on both the entry and exit sides in order to run the copper strip at a constant speed in the center during these operations. It is equipped.

ストを低減する事を目的とする。However, while the loop car is moving on the entry side, it is necessary to keep the tension of the copper strip constant in the central part (processing tank). In many cases, tension is controlled using a tension meter. In other words, a tension meter and a dancer roll are installed between the loop car on the entry side for receiving the coils and the processing tank in the center, and these are used to detect the tension of the copper strip and calculate the torque of the electric motor of the entry side priddle roll. The tension of the copper strip entering the treatment tank is kept constant by controlling the tension. According to this method, it is possible to keep the tension of the copper strip constant, but equipment costs, especially equipment costs such as installing a tension meter and dancer roll on the inlet side of the treatment tank, and the detected tension There is a drawback that the design and equipment costs of the electric control system that backs up the torque of the priddle roll and the cost of the equipment are high.' The present invention reduces the cost of equipment to keep the tension of the steel strip in the treatment tank constant. The purpose is to reduce

まりはプライドルロールの１ヘルクで補償する。The biggest cause of fluctuations in the tension of the copper strip in the treatment tank is the movement of the loop car at the entrance. Therefore, in the present invention, the tension fluctuation caused by the movement of the loop car is compensated for by the current supplied to the drive motor of the prydle roll between the loop car and the processing tank, that is, one herk of the prydle roll.
以下に図面を参照して本発明の詳細な説明する。The present invention will be described in detail below with reference to the drawings.

is connected to the central part by a loop car after the priddle roll 2 on the entry side. The loop car includes a fixed part 4 equipped with a wire winding drum equipped with a plurality of steel strip tension rollers, and a fixed part 4 equipped with a wire winding drum equipped with a plurality of steel strip tension rollers; By driving the cart 3 to the left, the amount of steel strip accumulated between the fixed roller SR and the cart 3 is reduced.
By driving the cart 3 to the right, the amount of steel strip accumulated between the fixed roller SR and the cart 3 increases. The leading edge of the trailing steel strip is welded to the tail end of the leading steel strip before reaching the entry bridle roller 2 on the entry side. At low speed or when stopped, the truck 3 is driven to the left, and the copper strip between the fixed roller SR and the truck 3 is sent out to the bridle roller 5 immediately after the loop car. When the leading edge of the trailing steel strip is welded to the tail end of the leading steel strip, the copper strip is sent to the entry side, and the trolley 3 is driven to the right to fill the steel strip reservoir between the fixed roller SR and the trolley 3. Increase the amount of filling.

Since the total tension inside the loop car is set constant, the exit tension (
(direction of arrow 1b) becomes higher. This outlet tension (1b) passes through the priddle roll 5 and causes the tension (1c) of the copper strip in the processing tank 6 to become excessive.
