Which heat treatment furnaces can be insulated with refractory ceramic fiber cotton? First of all, let’s know what the heat treatment furnace is and whether the furnace temperature is within the bearing range of ceramic fiber products.
Heat treatment furnaces are divided into annealing furnace, quenching furnace, tempering furnace, normalizing furnace and quenching and tempering furnace, which are mainly used for annealing of large carbon steel and alloy steel parts; Tempering of surface quenched parts; Heat treatment processes such as stress relief annealing and aging of weldments. Heating methods include electric heating, fuel oil, gas, coal and hot air circulation.
The service temperature of ceramic fiber products ranges from 800 ° C to 1400 ° C. There are 6 products of different materials corresponding to different temperature ranges. Alumina fiber products (such as sapphire annealing furnace) and zirconia fiber products can be selected at higher service temperature.
Annealing furnace is a new type of heat exchange equipment. Annealing furnace is an energy-saving periodic operation furnace. It uses energy-saving furnace lining and adopts ceramic fiber module + ceramic fiber blanket composite insulation structure to save electricity by 60%.
Annealing furnaces are mainly divided into well type annealing furnace, box type annealing furnace, bell type annealing furnace, continuous bright annealing furnace, etc. It is widely used in chemical industry, petroleum, food, metallurgy, machinery, light industry, electric power, shipbuilding, papermaking, mining, medicine, central heating and other industrial departments. With the development of social productivity, it is more and more widely used in various industries.
The furnace body structure adopts light steel frame structure, composite furnace lining and composite fiber furnace lining structure; With good thermal insulation effect and remarkable energy-saving effect, it is welcomed by the majority of users and is more and more widely used in the market.
The annealing furnace uses ceramic fiber module as furnace lining insulation material. Compared with the traditional insulation material, the energy-saving and thermal insulation effect is significantly improved.
Characteristics of ceramic fiber module and supporting materials:
1. Energy saving, good heat preservation effect and long service life.
2. The unit weight is low, heavy and light, and the average unit weight is 220kg / m3, which is 1 / 10 of heavy refractory and 1 / 5 of light insulation brick, realizing the lightness of kiln top and kiln wall.
3. Low thermal conductivity (less heat loss) and low heat storage.
4. Strong thermal shock resistance and no oven drying.
5. Stable chemical properties and strong corrosion resistance
6. Strong professional ability and fast construction efficiency.
