Background
The forging heating furnace has higher requirements on the refractoriness and thermal shock performance of the furnace lining material, so the furnace type traditional furnace lining material generally adopts a heavy castable and refractory brick structure. However, the conventional heavy weight liner has the following disadvantages:
A. the heavy lining has large volume density and heavy load of a steel structure.
B. The heat conductivity coefficient of the heavy lining is high, the temperature of the outer wall of the furnace body is high, and the heat loss is large; the operating environment of workers is severe.
C. The specific heat capacity of the heavy lining is large, the heating and cooling time of the hearth is slow, and the heat loss is high.
D. The heavy lining has poor resistance to rapid cooling and rapid heating, the lining is easy to crack or damage, and the maintenance of the lining after damage is difficult.
E. The construction environment is severe.
In recent years, with the upgrading of heat insulating materials, a forging heating furnace gradually starts to apply a full-fiber structure, and a chromium-containing fiber module is one of the products. Since Cr2O3 is not stable at high temperatures, is easily volatile at high temperatures, and is oxidized again to CrO3 in an oxidizing atmosphere, this hexavalent chromium (Cr +6) oxide is an ecologically very harmful substance, and IARC (international commission on cancer research) classified hexavalent chromium into human carcinogens (group 1), in combination with animal experiments and epidemiological investigations. In fact, the production of chromium-containing materials has been forced to be stopped in foreign countries. In recent years, with the continuous establishment of environmental regulations, the awareness of environmental protection is further improved, and many domestic enterprises seek new technologies to promote the development of chromium-free materials.
The traditional furnace type structure is an all-steel plate structure, and the fiber lining is easy to cause large through seam due to shrinkage deformation under the high-temperature environment: the fiber lining anchoring piece falls off, the outer wall steel plate is deformed and even burnt through due to serious overtemperature of the furnace wall, and the maintenance is difficult.
