SU28495A1 - Method of manufacturing refractory bricks for laying metallurgical furnaces - Google Patents

Description

By means of the proposed method, refractory brick is meant to achieve an increase, mainly, in the fire resistance of the vaults, and of regegen, open-hearth furnaces. /

In the schematic of FIG. 1-3 illustrate the framework for a standard brick in the three projections of FIG. 4-6, the framework for a vaulted brick.

The refractory brick produced according to the proposed method is an iron frame made of tin. The size of the frame is made in the shape of a brick. In particular,

The drawing shows a normal brick (standard) 1 and a molded brick 2. These frameworks are filled with a composition consisting of ground chromic ore, magnesite and refractory clay. Approximately 60% of ground chromic ore is taken, 35% of magnesite and 5% of refractory clay.

The brick prepared in such a way goes to the laying without preliminary firing. When welding heat, ore and iron (frame) form a refractory oxide and, in addition / chromium ore itself and magnesite have a temperature much higher than the dynas, and therefore laying will cost, according to the inventor, a longer time.

The subject matter of the invention.

The method of making bricks for masonry of metallurgical furnaces, such as vaults of open-hearth furnaces, etc., OTAI, is based on the fact that the masonry is filled with chromic ore, magnesite and refractory clay filled with modal metal bricks without prior calcination of the latter.
