Introduction

LJ ceramic fiber module is made of ceramic fiber blanket which is folded or cut by experienced professionaltechnicians. It use special equipments for producing module to confirm the precise dimensions and keep smooth surface ofmodule, designed for various of thermal furnaces. The products have some characteristics, such as reliable quality, quickinstallation, superior insulation properties.

LJ ceramic fiber module use the enhanced M-type anchors, which havegreater strength, closer to the cold face. It can make sure the strength in hightemperature. The fixed link was welding together with the high quality heat-resistance steel and stamping butterfly plate. The two round fixed link wereembedded in the module system, enlarged the bearing area and ensured thefirm of anchor system.
