PROPERTIES OF STONE WOOL PRIMARY FIBER LAYERS PRODUCEDWITH DIFFERENT CONTENTS OD BLAST FURNACE SLAG

Among the inevitable by-products of the metallurgical industry, special importance is given to waste from the iron and steel production. The blast furnace slag is not only the by-product, but rather it is also of a valuable resource as a substitute for the natural mineral aggregates. The chemical composition of blast furnace slag is similar to the composition of natural mineral rocks and is recognized as a potential raw material in stone wool production. The primary layer formation process is an important part of the mineral wool production line and it was simulated experimentally on a model of the spinning machine. This paper presents research of the mineral fibers mechanical properties based on mixture of blast furnace slag and diabase. Based on the results of a study carried out on the formation and the properties of stone wool fibers, it can be concluded that the blast furnace slag as a dominant component can be used to produce stone wool.
