Ceramic fiber products such as insulating ceramic fiber module are emerging thermal insulation material, which can be used in the equipment of chemical and metallurgical industry. The construction steps of insulating ceramic fiber module are important in normal construction.
1、 Anchor bolt welding
During wiring, the centerline of the wall panel must be taken as the benchmark, and the wiring must be carried out to both sides. The bolt position mark must be made in strict accordance with the design drawings. The accumulated error of the size that may occur in the actual setting out can be shown in the position of the last row of bolts.
1. The anchor bolt must be welded perpendicular to the furnace wall plate, and the deviation between the adjacent centers of the bolt is ≤ 2mm, and the deviation between any two centers is ≤ ± 3mm.
2. The welding must be firm. After welding, hammer and bend one by one to check the welding quality and clear the welding slag.
3. Attention must be paid to the protection of the the thread of anchor bolts.
2、 Back lining installation
1. It must be compressed to the required thickness in strict accordance with the design requirements.
2. The seams between blankets must be staggered, and the staggered amount shall not be less than the drawing.
3. The fast card must be clamped tightly to prevent rebound.
Next issue we will continue to introduce construction steps and precautions of insulating ceramic fiber module for furnace lining. Please stay tuned!
