ABSTRACT
We present here the most current thermal and mechanical material property data
of normal density, 112 pcf (identified as KN), and high density, 116 pcf (identified
as KD), silica brick used in coke oven walls. Coke ovens are used to produce coke
for processing iron ore in blast furnaces to make iron. The property tests on the
silica brick were conducted by RWTUV, Essen, Germany, and three other testing
facilities to be cited below. The testing program was coordinated during 1999 by
Dr. Hans-Dieter Potsch at RWTUV with the assistance of Dr. Uhlig and is docu-
mented in (1). The tests were conducted on brick samples, mortar samples, and
brick/mortar composite samples. The brick/mortar composite samples reflect the behavior brick and mortar joints in the actual coke oven walls. This data
can also be applied to other silica brick/mortar joint refractory lining systems. A considerable number of silica brick-only, mortar-only, and brick/mortar
samples were tested. As a result of page limitations in this chapter, representative
typical sample data are provided. Average data from a large number of samples
are presented in some instances. Due to the nature of silica refractory brick man-
ufacturing, it is expected that there will be some variation from brick to brick in
material property values. However, the data presented here can be used to provide
insight into the trends of mechanical material properties of silica brick. The
unique brick sample data, mortar-only sample, and brick/mortar composite data on refractory material properties in this chapter are typically not found in
the literature.
