In the OAO Borovich Refractory Combine there is a working structure for developing output of chamotte
block components of the lower structure of glass melting furnaces. Features are considered for the production
technology of components and engineering lines, modernization of equipment, and the provision of product
quality. Physicochemical properties are given for component grades ShSU-33 and MLS-62, and their
advantages over similar products of other producers are indicated.
Block components are used traditionally for lining the
bottom of the melting bath of glass-making furnaces .
Before the start of using melting and casting baddeleyite-
corundum components, large aluminosilicate components
due to their considerable size and minimum number of joints
have provided the required engineering life of a furnace bath,
and subsequently structural stability of the lower structure of
a furnace and the required heat insulation. Recent attempts to
replace fired chamotte components by concrete, are not
promising. Unfired low-cement concrete components require
“a smooth heating-up campaign to the operating tempera
ture” , as a result of which on heating they experience a
continuous series of chemical and phase transformations:
cement dehydration, formation of calcium aluminates, their
reaction with aluminosilicate components of the matrix, in
the course of which article stresses accumulate with a
capacity to lead to breakdown. All of the concrete objects
(fired and unfired) contain calcium aluminate, less chemi
cally resistant to silicate glass, particularly at high tem
Until recently the only Russian producer of block
aluminosilicate objects was the Podol’sk Refractory
Component Plant. In 2005, in connection with the closure of
chamotte production, the management of OAO Podol’sk
ogneupor asked a number of existing refractory enterprises
to purchase from it some production lines with complete
technical and production provisions in order not to lose in
Russia refractory production in demand by users. OAO
Borovich Refractory Combine (OAO BKO) responded to
this request by implementing together with the Podol’sk
Refractory Plant a plan for moving a production line for
producing refractories required by glass enterprises to the
