This study describes the role of in situ nano SiC whiskers on the strength and density of alumina silicate–SiC-carbonrefractory compounds. The prepared specimens were composed of 65 wt. % chamotte as alumina silicatecompound, 15 wt. % SiC-containing material regenerates and 10 wt. % fine coke and 10 wt. % liquid resole asbinder. Different values of additives (such as silicon a...

The article presents an analysis of methods that can be used for low‑tonnage production ferromanganese, ferrosilicon and other ferroalloys in the conditions a machine‑building enterprise using its own waste, including dispersed. It is proposed to carry out rotary tilting furnaces (RNP) new generation, which have maximum efficiency when heating melting dispersed materials, allow active oxidation...

Microsilica, or silica fume, is an amorphous type of silica mostly collected as byproduct of the silicon and ferrosilicon alloy production. In this work, low shrinkage alumina-mullite ceramic composites were prepared from mixtures of calcined alumina, silica fume and aluminum metal powder and sintered at 1550 o C for 2 hrs. The influence of silica fume and aluminum powder on the densification p...

Recycling or utilization of industrial waste is becoming more popular as people become environmentally conscious. Silica fume a by-product the smelting process in silicon and ferrosilicon industries. This study examines mechanical behavior steel tubular composite column filled with conventional concrete silica experimentally under axial compressive loading. For study, variability tube thickness...
