11.5 Refractory Manufacturing

 · Refractory manufacturing involves four processes raw material processing forming firing and final processing. Figure 11.5-1 illustrates the refractory manufacturing process. Raw material processing consists of crushing and grinding raw materials followed if necessary by size classification and raw materials calcining and drying.

(PDF) The drying behavior of high-alumina ULC refractory

When the permeability of the body is sufficiently high or the heating rate is low no significant pressure build-up is developed during the heat-up and the water loss can be considered mainly influenced by the rate of water converted to steam by boiling.The cause of the third drying stage related to the small peak in the derivative curves is not yet clear but one hypothesis is that the steam flow exiting the body during the second stage

Refractories are enabling materials in that their primary function is to facilitate the production of other materials such as metals glasses petrochemicals and cements. They have enabled the utilization of heat to make materials since the Bronze Age. Although in recent years a number of studies concerning the many complex variables that determine the rheologic hydraulic and ceramic

Drying Stages during the Heating of High‐Alumina Ultra

 · The purpose of this work was to investigate the drying kinetics of high-alumina ultra-low-cement refractory castables under continuous heating conditions. Three main drying stages were identified during the castable heat-up and were related to the phase change of free water and to the decomposition of hydrated products present in the body. A clear correlation was found between the actual heating profile inside the castable

Fast drying of high-alumina MgO-bonded refractory castables

 · Designing and processing crack-free high-alumina MgO-bonded castables are huge challenges for refractory producers as not only cracks and flaws can be generated during the curing step of the prepared samples (due to brucite formation and its non-accommodation in the microstructure) but also the first heating treatment of such materials may lead to their spalling or explosion as a consequence of a combination of low permeability and high

Refractory Castable Drying and Dehydration

 · Therefore we must do a good work of drying and dehydrating castables. The dehydration of refractory castables is divided into three stages. The first stage is at a temperature of 100°C. The mechanism is to remove free water and the dehydration speed starts at a temperature between 50 and 60°C. Second stage.
