Description

technical field [0001] The invention relates to a flexible and environment-friendly fireproof cable continuous rolling and continuous annealing processing unit, which is mainly used for the rolling production of fireproof cables. technical background [0002] At present, there is no fireproof cable rolling production equipment in the world. In my country, more than 90% of the rolling processing equipment used by the hard-to-deform alloy seamless pipe production plant are improved products based on the design of the Luoyang Mining Machinery Factory in the 1950s and 1960s, and did not break through the Russian old-fashioned rolling mill model. The rolling speed is low, the movement impact is strong, the noise is loud, easy to be damaged, and the product precision is low. They are all used as blanks, which are far from meeting the needs of high-speed and high-quality development of the domestic economy; foreign production of hard-to-deform alloy tubes, rods and wires is rolled ...

Problems solved by technology

In my country, more than 90% of the rolling processing equipment used by the hard-to-deform alloy seamless pipe production plant are improved products based on the design of the Luoyang Mining Machinery Factory in the 1950s and 1960s, and did not break through the Russian old-fashioned rolling mill model.

The rolling speed is low, the movement impact is strong, the noise is loud, easy to be damaged, and the product precision is low. They are all used as blanks, which are far from meeting the needs of high-speed and high-quality development of the domestic economy; foreign production of hard-to-deform alloy tubes, rods and wires is rolled The manufacturers of processing production lines mainly include Russian Electric Steel Heavy Machinery Co., Ltd. and German MEER Company; the technological progress of cold-rolled pipe mills in Russia has been slow, especially in the past ten years. , energy saving and other aspects of the design have been greatly improved, the rolling frequency has been greatly increased, the highest can reach 120 times / minute, the small and medium-sized unit has the characteristics of high speed, high rigidity, small inertia, small impact, high synchronization accuracy, etc., widely used in Copper and copper alloy, stainless steel, titanium alloy and zirconium pipe processing; German MEER pipe cold rolling mill is highly respected, but because of its high price, there are not many newly introduced MEER rolling mills in China. The transmission, balance and other aspects represent the highest level of the current rolling mill development. Its shortcomings lie in the synchronous mode of feeding, the rotation of the chuck and the bearing archway. Because it uses servo motors for feeding and rotation, the motor starts and stops frequently. As a result, the heat of the motor is high, which affects its service life and limits its operating frequency. At the same time, because it uses a moving roll frame to bear the load, in order to ensure the rigidity of the equipment and meet the rolling force, the weight of the roll frame needs to be increased. During the working process, it moves back and forth, and blindly enlarging the roll stand will increase the impact during the operation of the equipment, so the improvement of its rolling frequency and rolling precision is limited to a certain extent.

As a big and powerful country in the world of high-precision copper tube production, China's overall equipment manufacturing level is in the forefront of the world, but in the field of high-speed continuous induction annealing equipment for copper tubes, it cannot meet the input power requirements of high-speed continuous induction annealing; the annealing speed and power (temperature) control is accurate Poor performance; technical bottlenecks such as low automation control level, poor annealing production efficiency, annealing quality, and automation control level
