Abstract
The invention relates to a phosphate bonded castable adopting a composite hardening accelerator, belonging to the technical field of refractory materials. The phosphate bonded castable is prepared from the following main raw materials in percentage by mass: 55-75wt% of aggregate, 9-40wt% of powder material, 5-16wt% of composite hardening accelerator, 0.1-0.25wt% of corrosive inhibitor and 8-18wt% of bonding agent, wherein the aggregate is corundum or high-aluminum bauxite; the powder material comprises 0-37wt% of corundum powder, 0-37wt% of bauxite powder, 1-8wt% of SiO2 micropowder and 3-12wt% of alpha-Al2O3 micropowder; the composite hardening accelerator is pure calcium aluminate cement and rho-Al2O3 micropowder; the corrosive inhibitor is an NH66 type inhibitor, and comprises the main chemical component of bismuth oxyiodotannate; and the bonding agent is phosphate (aluminum phosphate solution), and the P2O5/Al2O3 ratio is 1/2.5-1/3.8. The phosphate bonded castable has the advantages of high strength, wear resistance, thermal shock resistance, short stripping time, capability of being quickly baked and the like, and has excellent high-temperature resistance.
Description
Technical field
The present invention relates to fire resisting material field, be specifically related to a kind of phosphoric acid salt of compound accelerator for hardening that adopts and combine mould material.
Background technology
Phosphoric acid salt combines mould material to have good thermal shock stability, and compressive strength is high, and wear-resisting, anti-high-performance such as wash away is widely used in the furnace lining material of various thermal kiln furnaces.
But phosphoric acid salt commonly used at present combines the accelerator for hardening that mould material adopted to be mainly high-alumina cement and MgO fine powder, and when adopting high-alumina cement to cook accelerator for hardening, the CaO of introducing has reduced the high-temperature behavior of material; When adopting the MgO fine powder to cook accelerator for hardening,, cause the construction technology difficult and complicated because MgO fine powder and phosphate reaction are rapid.Simultaneously,, make phosphoric acid salt commonly used at present combine mould material to need ageing mixture in use, make troubles to construction because the bed blending raw material has been introduced part metals iron in shattering process.
Summary of the invention
The objective of the invention is to study a kind of phosphoric acid salt of compound accelerator for hardening that adopts and combine mould material; The technical problem that solves provides a kind of phosphoric acid salt of compound accelerator for hardening that adopts and combines mould material; Through adopting compound accelerator for hardening to solve its ambient cure problem, normal temperature is cure and demold normally, after the high-temperature heat treatment; Because reduced the introducing amount of CaO, it has the good high-temperature performance; But advantages such as that this material has is high-strength, wear-resisting, anti-thermal shock, the short quick baking of demould time, and has the good temperature resistance ability.
The technical scheme that the present invention adopts is:
