1. The plastic refractories can have high refractoriness and high flexural strength. Its function is to directly contact the flame in the furnace and resist the erosion of the furnace gas. According to the difference of working temperature of various parts inside the furnace body, different grades of plastic can be selected to reduce the construction cost.
2. The thermal insulation coefficient of the lightweight thermal insulation brick is between the plastic and the fiber refractory material, and its working position is also between the two. However, because there are many parts in the furnace body that are in direct contact with the plastic and fiber refractory materials, the calculation of the heat dissipation of the furnace body is based on the refractory material with the smallest thermal conductivity, so its chemical composition and physical properties can be neglected.
3. Because of the large thermal conductivity of plastics, in order to reduce the energy loss of the reheating furnace and improve the resource use efficiency, a fiber refractory material with very low thermal conductivity is designed and used together. Compared to plastics, fiber refractories can be considered as 0, ie insulation materials.
4. According to the particularity of the furnace body and the convenience of construction, fiberboard is used in the furnace wall, and the fiber blanket is used at the top of the furnace. Because of the limited space in the roof, a thin ceramic fiber blanket with a lower thermal conductivity is used.
