Abstract
The invention discloses a low aluminum porzite refractory castable, comprising 70 to 75 percent of porzite M45 and flint clay, 10 to 18 percent of porzite powder, 6 to 7 percent of pure calcium aluminate cement, 2 to 4 percent of Alpha-AI2O3 micropowder and 3 to 5 percent of siliceous dust according to mass percentage. The refractory castable has strong resistance to chemical attack, can not cause the cracking and spalling of the lining, and has long service life.
Description
Technical field
The present invention relates to refractory castable, particularly a kind of low aluminum-containing mullite refractory castable.
Background technology
The mould material that use at existing domestic new type nonaqueous cement production line kiln hood cover position is high alumina matter material, though the mould material of this kind material is the intensity height at high temperature, wear resistance is good, but high alumina refractories at high temperature forms the mineral facies based on corundum, corundum at high temperature reacts with alkali mutually easily, thereby the generation volumetric expansion deforms, stress concentration appears, consequence such as cause the wadding crack, peel off.Because kiln hood cover place constantly is subjected to washing away of hot grog in the rotary system, adds the frequent variation of thermal parameter, the work-ing life of kiln hood cover top refractory castable is generally shorter, generally about 1 year, has a strong impact on the operation factor of whole kiln system.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of low aluminum-containing mullite refractory castable, and resistance to chemical attack is strong, can not cause the wadding crack and peel off long service life.
