AB  - Ventilation mill for grinding coal is one of the main steam
power plants in the system that makes a significant influence
on the level of energy efficiency with its work. Working
parts of the device during exploitation are dominantly
exposed to intensive abrasive and erosive wear and also to
impact loading at elevated temperatures, which can lead to
damage and fracture of homogeneous materials, thus
shortening their working life. The consequences are the
reduction in mill production capacity and its ventilatory
effects compared to the projected value, as well as frequent
delays due to parts replacements, that significantly affects
the productivity, economy and energy-efficiency of the
system.
In order to determine the optimal technology for
revitalization of the damaged impact plates the experimental
model-hardfacing was engaged and different technologies
and additional materials were used. Three technologies archardfacing
were applied (MMA, SMAW and gas welding -
G) and eight additional materials with different chemical
composition and properties (Fe-Cr-C-Si, Fe-Cr-C-Si-Ti, Fe-
C-W-Co-Ni-Si, Fe-Cr-W-B-Nb-Mo-C, W-Fe-C and WC-Ni-
Cr-Si-B). The aim of this paper is to make the selection of
optimum welding procedures and additional materials and
hardfacing technology definition based on the results of
structural and mechanical properties of samples of
experimental model hardfacing. Cutting the samples for
mechanical and structural tests is performed with water jet
cutting using hardfaced test plan. Investigation of its
macrostructure has been done, diagrams of distributions of
hardness have been made, zone of the surface layer and
HAZ-a, and the degree of mixing for all hardfaced samples
have been defined. In addition, microstructural analyses
were obtained with optical (OM) and scanning electron
microscopy (SEM). The choice of additional materials and
hardfacing procedures which were applied in the hard facing
impact plates ventilation mill has been made based on the
results of this research paper.
