Everyone is familiar with ceramic fiber module. Ceramic fiber module is a kind of refractory and an essential basic material for the development of high temperature technology and iron and steel industry. Refractory materials such as ceramic fiber module and the development of modern industrial technology are interdependent and progress together. Throughout the development of smelting history, it is not difficult to see that every major technological innovation in the metallurgical industry will be accompanied by the advancement of refractories with the times.
The advantages of ceramic fiber module are not described one by one, and there are some disadvantages in the use of ceramic fiber module. For example, light fiber materials, although alleviating the load-bearing of the industrial furnace to a great extent, are not resistant to wind erosion and are limited to use in the furnace with high wind speed; The installation methods such as setting out, drawing and welding of anchor nails are cumbersome, which consumes a lot of manpower and material resources.
The appearance of ceramic fiber integral module makes up for this defect.
Ceramic fiber integral module is a large-scale fiber blanket block assembly developed for thermal equipment or local insulation of equipment with complex structure and fast flue gas flow rate. It is an integral block made by cutting the integrated large-scale fiber blanket block into neat small blocks and inserting anchors in the middle. The overall module has low thermal conductivity, flat surface, flexible size, thickness between 150mm and 300mm, and volume weight of 160 ~ 240kg / m3, which can meet the thermal insulation requirements of thermal equipment at different temperature levels from 600 ℃ to 1350 ℃. During installation, the module can be compressed in multiple directions to eliminate the thermal expansion stress under high temperature environment. The integral ceramic fiber module does not need to be bound with packing belt. The anchor is composed of yoke metal skeleton and round pipe support. Compared with the traditional ceramic fiber module, the production process of the integral module is simple and fast, which greatly shortens the production time.
The anti flue gas scouring performance of the overall module is due to the formation of a curing layer on the hot surface of the blanket after high-temperature calcination, which enhances the surface strength of the module. At the same time, the overall performance of the module lining is enhanced, and the resistance to wind erosion is up to 40 ~ 4m / S (air velocity). As a special lubricant that helps to improve the fiber forming rate is added to the overall module in the production process, which can soften the fiber, the fiber will not be crushed and broken when the module is compressed during lining construction and installation; After reheating, the oil volatilizes, which has no adverse effect on the heat resistance of the module. The seamless structure enhances the fire-resistant and thermal insulation effect of the whole module.
Compared with the traditional ceramic fiber module, the integral ceramic fiber module has its unique advantages:
1、 The whole module is interwoven with fibers, which avoids reducing the thermal conductivity due to different thermal insulation effects in different directions of the folded module, strengthens the thermal insulation effect and reduces the heat loss of various thermal equipment;
2、 The overall module surface is flat, and a layer of coating is applied on the module surface to prolong the service life and wind erosion resistance of the heat-resistant lining;
3、 The special anchoring method solves the problem of slow installation speed of traditional modules. The special automatic welding gun is adopted to make the lining construction simple and rapid;
4、 It can be compressed and expanded in all directions to alleviate the thermal stress of the furnace;
5、 Shorten the production cycle and supply quickly;
6、 Each module adopts a set of anchors, which can be easily replaced during local maintenance.
7、 It can be cut arbitrarily. It is suitable for heating equipment with complex shape and fast flue gas flow rate, which widens the application field.
