The Application of Ceramic Fiber Module in Industrial Furnace
Date:2016-09-09 16:05 | From:Zhengzhou Sunrise Refractory | Author:admin
Ceramic fiber is a kind of fibrous high temperature resistant material with soft and whippy in the 1970s, it open up a new approach for industrial furnaces and other thermal technology equipment
of energy-saving reform. Ceramic fiber as a lightweight, the highly effective refractory insulation materials, has light weight, good thermal insulation performance, convenient to construct,
without lining baking and many other advantages, so at present it is the most widely used industrial furnaces lining material. Ceramic fiber has very low thermal conductivity, used for furnace lining
to reduce furnace wall cooling, has better energy saving effect. At the same time because of the characteristic of low thermal inertia, makes the temperature control of reheating furnace changes
more convenient, so the ceramic fiber (module) as furnace lining widely used in the heating furnace of steel industry.
1. The application of ceramic fiber module in the steel industry: the traditional industrial furnaces refractory lining weight is bigger, furnace heat storage waste is serious, the heat preservation
effect is poor, furnace grim temperature is over 100 ℃, furnaces temperature is difficult to precise control. In recent years, industrial furnace refractory lining of the furnace wall used in the design of
the whole fiber lining, due to the fiber of low thermal conductivity, low density, light weight, when designing construction of the kiln, all adopt lighter steel support structure, which makes the
development of the industrial furnace into the era of "kiln lightweight" kiln. Fiber heat storage is small, to adapt to the rapid heating and cooling mode of operation. Moreover fiber modules can be
processed into different products, to adapt to the furnace shell inner wall various shapes. Fiber module has good mechanical vibration and impact resistance, chemical stability is also better,
these advantages play an important role to the development of new type kiln.
2. The heat-resistant technology development trend of ceramic fiber module: the main bases of ceramic fiber are Al2O3 and SiO2, common ceramic fiber Al2O3 content is lower, the formation of
fiber can not separate out mullite phase, known as: amorphous alumina oxide of ceramic fiber, the using temperature is around 1000 ℃. In recent years, developed a crystalline aluminum oxide
ceramic fiber. The Al2O3 content reaches over 72%, melting point is very high, can separate out a homogeneous mullite phase rystal, known as the crystalline aluminum oxide ceramic fiber. The
heat resistant temperature can reach 1 600℃.
At present, energy saving, environmental protection, prevent the earth warming has increasingly become the focus of world attention, fuel costs will become the bottleneck of iron and steel industry
development. Industry furnace, especially iron and steel industry furnace, when designing, should adopt ceramic fiber module as furnace lining as far as possible, should try to use maintenance
time for the old heating furnace, change the carpet type lining or refractory brick or layer as ceramic fiber module structure, it is also an important measure to realize the sustainable development of
iron and steel industry.
