The introduction of a high degree of automation, such as robotic manipulation in metallurgical processes is no longer a difficult discipline with limited use although these processes are characterized by a specific environment that sets high demands on automation. Forging is a manufacturing process involving the shaping of metal using localized compressive forces where robot manipulates step by step through the forging process until the finished workpiece is removed from a forging press. In many such production lines people are still working in difficult working conditions with a high risk of injury. By replacing the worker with robots, the process becomes much safer and more efficient. Process automation in extreme environmental conditions requires a specific kind of know-how. The implementation of robots into metallurgical processes is a major challenge for robot manufacturers in terms of the robot's service life. The paper summarizes and shows the fundamental requirements that must be considered before designing and integrating robotic systems into these particular conditions.

The paper presents the review of works devoted to the material engineering – diagnostic and technological application of artificial neural networks (ANN). This review has been realized by activities created in narrow connection with the industrial sphere, mainly as a constructive step to development of Industry 4.0 philosophy. The review covers different materials measurement and evaluation. There have been investigated such materials as rubber blends, laminates, optical glasses; and also survey covers degradation processes appeared in industrial applications as well as the material defect evaluation and wearing diagnostics. The last part of the review offers output concerning infrared technique application of ANN. This review can serve as an inspiration for new challenges.

The work is dedicated to converting microwave radiation to heat. The article analyses different ways of heating residential and utility areas. Attention is paid mainly to infrared heating. Ceramic materials suitable for converting microwave radiation to heat from refractory ceramic composites are disclosed. The cooling curves of these materials after microwave heating are characterized in detail. The paper also presents a description of a microwave reactor with a fireclay brick together with the parameters of the living room heating.
