A comprehensive methodological approach is proposed for resolving metallurgical problems within the scope
of a multistage problem formula “composition – structure – properties” – “technology” – “thermal shock-cor
rosion-erosion-resistant material” followed by development of material technology and objects conforming to
refractory conditions and operating regimes in heating units. Practical scientific approaches are considered for
forming heat and corrosion resistant refractory materials. A general structural model is proposed for ceramic
refractory technology making it possible by computer modelling to perform systematic analysis, prediction
and calculation of specific technological parameters in the main production stages.
Keywords: ceramic refractory material, corrosion-erosion resistance, fragmentary structure, temporary pro-
duction binder (TPB), “floating” (“rigid”) skeleton, sol-gel process, highly concentrated binder suspension
(HCBS), melting and casting crucibles (technology).
State of the problem. Choice of specific minerals for
manufacturing refractory products is determined both by
technical and economic indices and also their extent in na
ture. Minerals that are most
Effective and of practical interest for refractory technol
ogy are those containing the oxides SiO
, MgO, CaO,
and their compounds. Apart from these oxides
in refractory technology there is extensive use of carbon, ni
trogen, phosphorus oxides, and also compounds obtained
with participation of synthesis through solid- and liq
uid-phase reactions. These materials relate to clinkers, spi
nels, sialons, nitrides, carbides, and other complex com
pounds, that have a polymeric structure.
Introduction into ceramic refractory mixes of small
amounts of special nano-additions and polymer compounds,
including organic compounds, makes it possible to change
and improve over wide limits the production properties of
mixes in preparing charges, with slip casting, compaction,
creation of refractory ceramic concretes, etc. The quality of a
finished product is improved with respect to such specific in
dices as density and porosity, thermal shock resistance, and
corrosion-erosion stability towards melts and gaseous media,
long-term mechanical strength and thermodynamic stability
in a working regime of variable thermal loads.
Design of refractories and refractory products com
mences with analysis of functional tasks carried out by them
in service. Schematically refractories are separated with re
spect to service conditions into three typical groups: 1) oper
ating at high temperature, but not experiencing chemical and
mechanical action; 2) operating at high temperature and si
multaneously experiencing mechanical action; 3) operating
at high temperature and experiencing chemical and mechani
cal action .
Solution of these tasks commences with material sci
ence, continued by development of highly effective material
and object technology, with a capacity to create basic condi
tions for organizing production. For this in the initial stage a
