Ceramic fiber module is one of the main products of Shandong Heat Shield. This product is designed to facilitate the construction process of industrial furnaces such as kilns and trolley heat treatment furnaces, and to improve the uniformity of the internal structure of the furnace and its beautiful appearance. Ceramic fiber modules are made of aluminum silicate fiber needle-punched blankets and prefabricated components. Ceramic fiber modules are also called “blocks” and “modules”. They are divided into two types: non-prefabricated anchors and prefabricated anchors. The ceramic fiber module can be fixed on the anchor nails of the steel plate of the industrial kiln shell to play a stable role. This insulation material has a good fire-resistant and heat-insulating effect, which improves the integrity of the fire-resistant and heat-insulation of the kiln. It is also the current refractory market A more commonly used thermal insulation material!
The aluminum silicate fiber insulation material product is fibrous, which looks like the cotton in the quilt. This type of insulation material is made into aluminum silicate needle-punched blanket after being melted at a high temperature with scorched gemstones through the process of blowing and spinning. The acid-aluminum needle-punched blanket is folded and extruded by a machine to become a ceramic fiber module. The conventional size of the module is generally 300*300*300mm or 600*300*300mm, which supports customization. In order to make the product more convenient for construction on industrial furnaces, A fixed anchor is added inside the module, which is directly fixed on the wall lining of the heating furnace with bolts, and can achieve a good fire-resistant and heat-insulating effect. The modules are squeezed against each other to better achieve the effect of heat preservation and heat insulation. Our company produces The refractory temperature of the ceramic fiber module is between 0-1400℃.
Product performance:
Excellent chemical stability; excellent thermal stability; excellent elasticity. The module is in a pre-compressed state. After the furnace lining is built, the expansion of the module makes the furnace lining seamless and can compensate for the shrinkage of the fiber lining to improve the heat insulation of the fiber lining Performance, overall performance is good; excellent thermal stability and thermal shock resistance; the ceramic fiber module is installed quickly, and the anchors are arranged on the cold surface of the wall lining, which can reduce the requirements for the material of the anchors. Insulation design and construction training can be carried out according to different furnace types of customers.
Application areas:
The lining of kilns in the petrochemical industry is insulated; the linings of kilns in the metallurgical industry are insulated; the linings of kilns in the building materials industries such as ceramics and glass are insulated; the linings of heat treatment furnaces in the heat treatment industry are insulated; and the linings of other industrial kilns.
Construction method:
(1) For the backing flat layer of the modular composite furnace lining, during the construction process, it should be uniformly pressed to the required density and thickness according to the design requirements. When the flat layer exceeds two layers, the backing between the layers The joints of materials should be staggered, and the staggered distance should not be less than 100mm;
(2) The anchors should not be determined by the module structure and its size. During the welding of the anchor nails, the verticality deviation is required to be less than 3mm, and the size deviation generated during the welding should be reflected in the next row of modules;
(3) If the connection between the module and the brickwork or other refractory lining is in the non-folding direction of the folded module, the expansion of the straight-through seam due to the shrinkage of the refractory product must be considered, and the fiber blanket should be folded and squeezed into the straight-through seam. In order to prevent the increase of heat loss and damage to the steel structure;
(4) For ceramic fiber composite furnace lining, for the battalion arrangement, the fiber shrinkage joints between different rows must be compressed and squeezed in half with the corresponding fiber blanket to compensate for the shrinkage. When this structure is used on the furnace roof, it must be fixed with heat-resistant alloy “U-shaped nails”.
