Successfully developed the largest rolling mill nut in China

At present, the crushing nut used in China's largest Baosteel roughing mill has been successfully developed in China's second heavy machinery group (double), and the “localization” of this product has taken a critical step.

According to the Science Times, Baosteel's preliminary rolling mill is a complete set imported from abroad and is one of the largest mills in the world. The pressing nut is an important part of the rolling mill pressing device. The nut weighs 2340 kg and is made of copper alloy material, mainly composed of screw and silk.

The function is to reduce the rolling force by the high-speed rotation between the screw and the nut, and the rolling force of up to 2000 tons is generated. Therefore, the pressing nut is different from the conventional rolling pressing nut, and the material is required to satisfy the heavy load. It has good strength, high wear resistance, high temperature resistance, seizure resistance, and better hardness matching performance. In addition, the replacement of the nut is carried out at the same time as the initial rolling mill shutdown, so the service life is required to be at least 6 years. .

In view of the strict requirements on the performance and service life of the pressed nut, and the fact that there are no manufacturers producing such products in China, Baosteel has been imported from abroad and is expensive. The two-way and Baosteel agreed to jointly conduct research on the localization of the product.

Researchers have researched and researched process parameters for more than a year, and developed a new material copper alloy with high wear resistance and anti-adhesive wear similar to tin bronze. Using this new material through special casting method and heat treatment process, Double has succeeded in manufacturing a pair of pressing nuts for Baosteel, and its performance indexes meet the requirements put forward by Baosteel.
