Insulation refractories (Refractory material) in a heat transfer process at absolute zero when casting refractory, refractories (Refractory material) lining in all the molecules are in a state of absolute rest, all molecular motion stopped, no thermal motion and heat passing phenomenon. When the start of the operation casting furnace refractories prices, temperature, molecular motion of the hot face lining material begins. With the furnace temperature, molecular motion and mutual collision accelerate gradually intensified. Molecular collision kinetic energy is transferred from the high kinetic energy of the molecule to the other low molecular kinetic energy, and the results flowing from the hot side hot cold casting refractories manufacturers, this heat transfer mechanism known as thermal conduction. Refractories (Refractory material) according to the chemical characteristics can be divided into three categories: (1) acidic refractories (Refractory material). Acidic refractories (Refractory material) is RO2 (SiO2 ZrO2) is the main component of refractories (Refractory material) casting refractories where to sell, is a typical acidic silica brick refractories (Refractory material), in addition to the oxidation zirconium products, half brick, clay brick, zircon products; Al2O3-SiO2-based material and Al2O3-SiO2-ZrO2-based materials are acidic refractories (Refractory material), such as: high alumina bricks, mullite brick, zirconium and zirconium corundum mullite brick brick.
