Abstract
The present invention relates to a kind of refractory materials, be specially the alkaline-resisting resistance to compression mould material of hard first, calcium hexaluminate is as aggregate, nano aluminium oxide is added in substrate material, improve density and intensity, the reduction sintering temperature of material, add silica flour as agglutinant, using pure calcium aluminate cement as bonding agent, water reducer and retardant regulate engineering time and workability simultaneously; The alkaline-resisting resistance to compression mould material of this hard first has low solubility, high resistance alkalescence erosion performance in iron content slag, particularly has very high stability under reducing atmosphere, has low degree of wetting and low thermal conductivity feature to molten metal and slag; The work-ing life of effective raising mould material and stability, reduce consumption and the shutdown maintenance number of times of mould material, be particularly useful for catalytic coal gasifaction stove.
Description
Technical field
The present invention relates to a kind of refractory materials, be specially the alkaline-resisting resistance to compression mould material of hard first.
Background technology
Under the hot environments such as catalytic coal gasifaction stove, traditional mould material is in iron content slag, and alkali resistant erosion performance is low, and unstable under reducing atmosphere, and thermal conductivity is high, easily weares and teares.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of alkaline-resisting, wear-resisting, measuring body mould material, under being specially adapted to the condition of reducing atmosphere.
Concrete technical scheme is:
The alkaline-resisting resistance to compression mould material of hard first, is made up of according to parts by weight following raw material, calcium hexaluminate 78 parts ~ 91 parts, nano aluminium oxide 5 parts ~ 8 parts, agglutinant 1 part ~ 6 parts, bonding agent 3 parts ~ 8 parts, water reducer 0.1 part ~ 0.3 part, retardant 0.1 part ~ 0.2 part; Calcium hexaluminate, nano aluminium oxide and agglutinant mix, packaging, and bonding agent, water reducer, retardant mix, and pack in addition.
Described agglutinant is silica flour.
The critical grain size of the alkaline-resisting resistance to compression mould material of this hard first is 5 ~ 10mm.
The alkaline-resisting resistance to compression mould material of hard first provided by the invention, calcium hexaluminate is as aggregate, nano aluminium oxide is added in substrate material, improve density and intensity, the reduction sintering temperature of material, add silica flour as agglutinant simultaneously, using pure calcium aluminate cement as bonding agent, water reducer and retardant regulate engineering time and workability.The alkaline-resisting resistance to compression mould material of this hard first has low solubility, high resistance alkalescence erosion performance in iron content slag, particularly has very high stability under reducing atmosphere, has low degree of wetting and low thermal conductivity feature to molten metal and slag.The work-ing life of effective raising mould material and stability, reduce consumption and the shutdown maintenance number of times of mould material, be particularly useful for catalytic coal gasifaction stove.
