With the development of the world economy, China's chain industry is full of vitality. Many new changes have taken place in production development, product structure, technical quality, market development, and economic operation, and many new achievements have been made. While we have made many achievements, there are still many problems in China's chain industry, such as insufficient brand effect, few high-end products, and difficult to guarantee the quality of chain steel.
In the high-speed offset press, the linear speed of the spindle bar teeth is very high. Take the j2204 offset press as an example. If the printing speed is 10000 sheets per hour, 2.77 sheets of paper will be passed per second. Therefore, the weight of chain teeth should be light, the arc transition should be large, and the number of chain rows should be small, which is conducive to high-speed printing.
