A New Type of Refractory Insulation Material -- Ceramic Fiber Products

A New Type of Refractory Insulation Material -- Ceramic Fiber Products

With the continuous development of science and technology, in addition to the traditional shaped fire insulation materials, ceramic fiber has gradually become a new, widely used industrial furnace fire insulation materials. Ceramic fiber, also known as aluminum silicate, is a light weight, heat resistance, low heat transfer, small thermal fiber lightweight refractory material. Ceramic fiber products include: ceramic cotton, ceramic fiber blanket, ceramic fiber shell, ceramic fiber board, ceramic fiber silica calcium board.

Application of Polycrystalline Mullite Fiber in Bell Kiln

Application of Polycrystalline Mullite Fiber in Bell Kiln

The selection of masonry materials for high temperature kiln is one of the important factors affecting the thermal efficiency of the kiln. In order to improve the thermal efficiency of the kiln, there is a trend from dense heavy type to light or light combination type in the world. Among them, the use of ultra-lightweight ceramic fiber as the kiln lining has gone from the experiment to the practical stage. The use of ceramic fibers in industrial kilns, especially intermittent kilns, is also a major technological reform in industrial kilns.

Polycrystalline mullite fiber composite products vacuum forming block on full hydrogen bell furnace

Polycrystalline mullite fiber composite products vacuum forming block on full hydrogen bell furnace

The bell furnace annealing of cold rolled strip is one of the key processes in the production of cold rolled sheet. At present, the all-hydrogen bell furnace is the most advanced type of annealing furnace. Anshan Iron and Steel Cold Rolling Sheet Factory put 76 all-hydrogen bell furnaces into operation in 1991 and 1995 respectively. Among them, 36 all-hydrogen bell furnaces started ignition production in May 1995 have been improved and improved in many aspects through the suggestions of Chinese and foreign technical experts and users. The most important improvement is to replace the lightweight refractory brick hearth lining with polycrystalline mullite fiber composite hearth lining.
