MODERNIZATION OF A FURNACE FOR IMPROVING TECHNOLOGICAL PROCESS FOR MAGNETIC MATERIALS SYNTHESIS

Vladimír Olah - Rastislav Dosoudil

   Preparation of newly developed ferrimagnetic materials, which are the subject of various magnetic measurements, requires rela-tively difficult heat treatment in high temperature furnace. Firing temperatures varies in the range 900 - 1300°C. The control of a furnace has to ensure the desired time-temperature profile. This paper deals with the modernization of the laboratory chamber fur-nace LKO IIM - 44K produced in 1986 yet in the former GDR.

Keywords: ferrimagnetic material, heat treatment, time-temperature profile, power transformer, control of a furnace
