AB'jTRACT: Magne8ite-chromite vault bricks are produced in the following

Department f*(,r R,:A'raCLor- Katerftls of che j(uznetsk-iy Metal-
lurgic Kombinat (BIX). A description of' the bricki, is given in
table 1. The magnesite-chromite vaults were constricted accord-
ing to a design by Frenkell (JNIIO). The highest degree of'
stability with the use of oxygen was obtained in the furnaces
of the "Zaporozhatal" Plant and of the Nizhne-Tagillskiy Metal-
lurgic Kombinat (Table 2). Table 3 shows the performance of
open-hearth furnaces of equal capacity with magneDite-chromite
vaultu. In another table data concerning equal furnacen of' the
NTKK are listed. In recent years unburned magresite-chromite
bricks were used for open-hearth furnaces of low capacity
Card 1/3 (Table 4). A description of port bricks is given in table 5.

Table 6 shows the stability of the upper rows of' the ports of
air regenerators. The performancesof porte and open-hearth
furnaces in the MMK are described in table 7. Another table
gives the consumption of refract,)ry material per ton oi' steel.
Conclusionst for furnaces operating intensively, as well as
those in which metal alloys are melted, the vaults should be
built of bricks containing periclase-spinellide or of high
density moignesite-chromite bricks burnt at high temperaturc,
respectively, according to the method of the UHIIO; magnesite-
chromite brickwork is suitable for the lining surface of the
slag-pocket vaults and the dinas walls ot the slag pockets; for
the brickwork of the upper furnace ports, where there are
oxygen ana very high temperatures, forsterite br~ck3 are rec-
ommended; in other furnaces it is advisable to use highiy
aluminiferous and dinas-chromite bricks; the quality of' the
magneeite-chromite vault bricks must be improved; the deneity
of the forsterite port bricks must be increased. There are
9 tables.
