Problems solved by technology
However, the existing water-quenching rollers have the following problems: 1. The friction and wear with the strip steel during operation is serious and uneven, resulting in a short service life of the water-quenching rollers and easy deviation of the strip steel; 2. The coaxiality of the water-quenching rollers is not high , the rotation dynamic balance is poor, and the roller surface jumps greatly, which leads to easy damage to the equipment. At the same time, the strip steel running tension fluctuates greatly in the production line, which affects the quality of the strip steel product

The present invention discloses a water quench roller and a preparation method thereof. The water quench roller comprises a core shaft, spoke wheel frames and a cylinder, wherein a pair of the spoke wheel frames are respectively arranged on both ends of the core shaft, the outer circle of the spoke wheel frame is fixedly connected with the cylinder, the outer periphery of the cylinder is uniformly provided with concave groove-shaped patterns, the spoke wheel frame positioned at the transmission side and the core shaft form an interference connection, the spoke wheel frame positioned at the non-transmission side and the core shaft form a sliding connection, and the cylinder is made from a wear-resistant stainless steel. The water quench roller of the present invention has characteristics of wear resistance, corrosion resistance, long service life, small radial run-out, good balance performance, stable operation, no strip steel skidding, effective equipment failure rate reducing, and strip steel surface quality protection.
Description
technical field [0001] The invention relates to a steel strip cooling device, in particular to a water quenching roll and a preparation method thereof. Background technique [0002] Rapid cooling after annealing is one of the core technologies for producing cold-rolled high-strength steel. Water quenching has the fastest cooling speed and the highest level of steel strength, so it is highly recommended by cold-rolled strip manufacturers. The water quenching system is mainly composed of water quenching tank, water quenching roller, spray cooling device, purging and drying device, etc. [0003] The water quenching roll is the steering roll in the water quenching tank, which plays a steering role in cooling the strip steel in the water quenching tank. and product quality have a significant impact. However, the existing water-quenching rollers have the following problems: 1. The friction and wear with the strip steel during operation is serious and uneven, resulting in a short...
