Abstract
The invention discloses a high-strength corrosion-resistant refractory castable which comprises the following raw materials in parts by weight: 50-60 parts of aggregate, 20-35 parts of powder, 5-6 parts of binding agent, 5-10 parts of zirconia fibers and 5-10 parts of yttrium oxide, wherein the aggregate consists of waste electroceramics, waste tiles and coal gangue; the powder consists of coal gangue, waste electroceramics, waste tiles, flint clay and silica powder; the binding agent refers to aluminate cement; and the additive refers to alpha-alumina fine powder.
Description
Technical field
The invention belongs to technical field of refractory materials, particularly relate to a kind of high-strength corrosion-resistant erosion refractory castable.
Background technology
Current refractory castable is generally by refractory aggregate, powder, bonding agent, admixture, solvent composition, and the starting material of refractory aggregate are generally magnesia, stone marble, perlite, spinel etc.Existing mould material erosion resistance is low, and produce the starting material consumed many, production cost is high.
Summary of the invention
In view of this, for the deficiencies in the prior art, the invention provides a kind of minimizing environmental pollution, cost is low and corrosion resistant high-strength corrosion-resistant loses refractory castable.
A kind of high-strength corrosion-resistant erosion refractory castable, comprise aggregate, powder, bonding agent, Zirconium oxide fibre and yttrium oxide, the parts by weight of above-mentioned raw materials are: 50 ~ 60 parts, aggregate, powder 20 ~ 35 parts, bonding agent 5 ~ 6 parts, Zirconium oxide fibre 5 ~ 10 parts and yttrium oxide 5 ~ 10 parts: wherein, aggregate is made up of the electroceramics that gives up, useless brick and tile and coal gangue, powder is made up of coal gangue, useless electroceramics, useless brick and tile, flint clay, silicon powder, described bonding agent is aluminate cement, and described additive is alpha-alumina fine powder.
The alkaline resistance properties of excellence of the present invention is to utilize coal gangue, useless electroceramics, useless brick and tile to have higher SiO
2content, under high temperature, liquid phase occurs that feature comparatively early realizes, when at high temperature running into alkali erosion, due to SiO in coal gangue, useless electroceramics, useless brick and tile
2high and the material surface of content appearance SiO comparatively early
2liquid phase, SiO
2the formation of liquid phase also can form protective membrane to the matrix of refractory materials; simultaneous oxidation zirconium fiber strengthens the erosion resistance of refractory materials further and utilizes yttrium oxide to keep the stability of Zirconium oxide fibre, effectively prevents alkalimetal ion to the erosion of resistance to material internal organizational structure.
Embodiment
