A heat treatment furnace is a general term for industrial furnaces used to carry out various heat treatment processes on metal workpieces. Heat treatment furnaces may adopt different furnace types; however, they require strict control of furnace temperature and internal atmosphere. Most heat treatment furnaces are heated by gaseous fuels. To achieve precise temperature control, some furnaces use electric heating. For continuous heat treatment processes, suitable continuous furnaces must be employed. For batch-type heat treatment processes, forced circulation of a controlled atmosphere is required, along with mechanized and automated furnace operation.
SUNTHERM ceramic fiber materials feature excellent properties such as high temperature resistance, superior thermal insulation, light weight, and strong thermal shock resistance. Replacing traditional dense refractory materials with SUNTHERM ceramic fiber as industrial furnace wall lining materials effectively enhances the furnace insulation structure, reduces heat loss, and achieves significant energy savings.
After adopting SUNTHERM ceramic fiber linings, the furnace walls become lighter and have lower heat storage capacity, which significantly increases the heating rate, shortens operating cycles, improves furnace productivity, and enhances operational flexibility. Due to the lightweight structure, absence of thermal expansion stress, and strong thermal shock resistance, steel consumption for furnace construction can be substantially reduced, enabling efficient and lightweight kiln and furnace structures. Once installation is completed, the furnace can be heated up and put into operation immediately without a drying-out procedure.
Technical Advantages of the Layered and Modular Combined Installation Method
The layered stacking combined with modular composite lining structure is one of the most widely used fiber lining structural forms. This structure offers the following advantages:
Ensures a long service life
Seamless lining design
Modules are compressed into an accordion shape; after installation, the packaging is removed, allowing the modules to expand and tightly interlock with each other
Individual modules are independently installed and fixed, making maintenance convenient and efficient
