TOWARDS THE DETERMINATION OF MODES FOR MOBILE TECHNOLOGY FOR PROCESSING LARGE-SIZED ROLLING SURFACES

The article considers the features of determining rational modes of machining rolling surfaces of rotary kiln supports using mobile technologies. It is proposed to estimate the service life of rotary kiln supports to determine the frequency of restorative machining of rolling surfaces. It is shown that this approach is feasible from the point of view of correct forecasting and determining the timing of the necessary restorative machining of the working surfaces of support parts to ensure reliable operability of the units. It provides a rationale for using the most efficient designs of mobile machine modules that ensure efficient restoration of the shape and size of large-sized rotating parts. A number of dependencies are proposed for determining rational machining modes. These dependencies take into account all technological machining modes that have the greatest impact on the quality parameters of the machined surfaces. It is proposed to use a finite element analysis software package to study deformations in the technological system. The sequence of modeling and evaluation of the stress-strain state of the built-in machine is given for various schemes of machining rolling surfaces of support rollers and tires of rotary kilns. A mathematical model has been obtained that will allow using the linear programming method to obtain rational modes for restorative treatment of surfaces of rotary cement kilns using mobile technologies
