Insulation refractories (Refractory material) in the second heat transfer process at the same time, present in refractories (Refractory material) stomatal pores in the air along the flow path from the hot face lining of cold cast refractories, which also put heat from the hot face lining to lining with a cold, this heat flow mechanism called convection. However, only refractories (Refractory material) are sold in the cast refractory Which, stomatal pore channels are usually small and casting refractories prices, great airflow resistance casting refractories manufacturers, thus refractories (Refractory material) convective heat transfer within the role of very small, usually negligible. What is refractories (Refractory material)? Refractories (Refractory material) generally refers to the refractoriness at 1580oC or more inorganic non-metallic materials. It includes natural minerals and purpose in accordance with the requirements of certain process made after a certain variety of products having a certain high temperature mechanical properties, good volume stability, the material necessary for a variety of high-temperature equipment.
