Abstract
The roller section located under the crystallizer in the continuous casting machine for slabs plays a critically important role in ensuring the quality of the slab. Its design features, as well as the technological parameters of casting, directly influence the characteristics of the finished metal. Due to the high temperature of the cast billet, reaching approximately 1300 °C, there is a problem of lubricant burnout and failure of roller bearings, leading to an increase in the volume of defects and frequent repairs. To address this issue, it is proposed to modernize the roller section by implementing an individual lubrication system for each bearing and axial cooling. These changes involve modifying the design of the roller shaft, which will help maintain optimal temperatures in the bearings and significantly extend their service life. It is expected that the modernization will reduce equipment downtime, improve the quality of the finished product, and enhance the overall efficiency of the production process.
