Compared with general refractory bricks, paving slabs are lighter in weight and have fine pores evenly distributed in the interior. The porosity is higher. Therefore, it can ensure that less heat is lost from the furnace wall, and the cost of fuel will be reduced accordingly. Lightweight bricks also mean less heat storage, so the heating and cooling will be faster, which promises to accelerate periodic operation. Paving slabs are suitable for temperatures ranging from 900 ° C to 1650 ° C. Paving slabs have low thermal conductivity, low heat capacity, and low impurity content. High strength, good thermal shock resistance, resistance to acid and alkali atmosphere corrosion, high dimensional accuracy.
When we usually use paving slabs, we can use them according to our own choices and uses, and make production security.
