Powder glazing

Specialists of company TET ESTEL developed for powder glazing furnaces a powerful source, consisting of four rectifiers switching parallel to 50 kA line current and 150 V voltage.

 

Rectifiers operate on a round-the clock basis, as the powder glazing process requires prolong agglomeration. Change of several melting phases and modes occur during process.
