- Title
EXPERIMENTAL STUDIES OF ELECTRODE COATING THICKNESS VARIATION AT PRESSING.

- Abstract
Oscillographic and mathematical statistics methods were applied to study the regularities of formation of coating thickness variation in experimental electrodes UONI 13/55 with 4 mm rod diameter at their manufacture in angle hydraulic press under the conditions maximum close to production ones. It is found that coating thickness variation is a continuous, multistage, nonmonotonic (wavelike) and harmonic process, in which disturbances, arising at the starting stage, can be felt in subsequent stages of electrode pressing. Coating thickness variation is caused, primarily, by violation of elasticity and viscosity balance, on which the consistency of electrode coating masses depends. At the same time the probability of appearance of coating thickness variations is essentially influenced by the features of forming path of electrode coating press.
