L&L Special Furnace Co. unveils retort furnace for de-bindering ceramic composites
The company is customizing a large retort box furnace for de-bindering ceramic matrix composite (CMC) prepreg materials.
L&L Special Furnace Co. Inc. (Aston, PA, US), designer of special industrial furnaces, ovens, kilns, quench tanks and heat-treating systems, announced the development a large retort box furnace for de-bindering ceramic matrix composite (CMC) prepreg materials. It is also suitable for powder metals processing and hot isostatic processing. The furnace, Model XLC3648, has a work zone of 29" wide by 29" high by 35" deep. It has a temperature uniformity of ±20°F at 1,100°F using six zones of temperature control, with biasing to balance any temperature gradients. According to L&L, the furnace is constructed of low-mass insulation that allows for quicker cooldown times. The XLC3648 also has a venturi blower to aid in cooling, controlled by a Eurotherm program control with over-temperature protection. A programmable flow panel manages the nitrogen flow throughout the process.
