MORGAN ADVANCED MATERIALS added a new type of insulating firebrick (IFB) to its range of furnace lining materials — the JM™-HD (high-density) series. Based on slinger technology, the bricks are made from kaolin and high-purity alumina, which react to form mullite during the firing process, where temperatures can exceed 1,400°C.
“The new range is a further example of how Morgan is recognizing and responding to changing customer and market requirements with the introduction of new, higher-specification IFBs,” commented Massimiliano Marchetti.
Morgan IFB products have gained recognition for their performance in terms of refractory qualities, consistent “permanent linear change” (PLC), thermal shock resistance and particularly low thermal conductivity.
The new products are used for a variety of applications across a number of industries, including the ceramic, chemical processing, glass, and iron sectors. Certain applications require a “higher than standard” cold crush strength (CCS), which prompted the Morgan research and development team to design a new kind of brick for both mass and batch production.
The JM-HD range has been tested extensively and meets all of the ASTM quality assurance standards. The products are available in numerous standard and special shapes, in JM 25 HD, JM 26 HD, JM 28 HD and JM 30 HD grades.
The slinger process is essentially the low-pressure extrusion of a wet clay mix containing high levels of burnout additives, with the additional processing step that the semi-extruded material gets ‘slung’ onto a continuous belt to generate additional porosity, before drying and firing.
