Abstract
The invention discloses a silicon carbide anti-skinning anti-plugging casting material and a preparation method thereof. The invention is characterized in that the silicon carbide anti-skinning anti-plugging casting material is prepared by mixing the following substances in parts by mass: 25-35 parts of 10-3mm high-silicon porcelain bottle particle, 35-50 parts of silicon carbide particle, 10-15 parts of 320-mesh silicon carbide fine powder, 3-6 parts of silicon carbide micropowder, 5-8 parts of cement, and proper amounts of antioxidant, water reducing agent and water. The preparation method comprises the following steps: evenly mixing the raw materials, adding the raw materials into a die cavity, compacting by vibrations, baking and curing to obtain the product. The material disclosed by the invention is easy for construction, has the advantages of high strength, wear resistance and skinning resistance, is applied to a predecomposition furnace conic section, smoke chamber, kiln tail slope and other positions of a large/medium cement rotary kiln, and has the characteristics of long service life, plugging resistance and skinning resistance.
Description
Technical field
The present invention relates to a kind of silicon carbide castable, belong to technical field of chemistry, anti-blocking mould material of particularly a kind of silicon carbide crusting resistant and preparation method thereof.
Background technology
Employed alumina-silica mould material in position such as the predecomposition furnace tapering of domestic and international big-and-middle-sized cement rotary kiln, smoke-box, kiln tail slope or refractory brick react concurrent unboiled water mud raw material with cement slurry and stop up in the environment for use of thermal shocking and rich alkali; Must use air bubble or water blast gun cleaning putty; Thereby cause the damage of the material at these positions, and then cause and stop the kiln maintenance.
In order to solve above-mentioned blockage problem, prior art has adopted the mould material of aluminium silicon, but this mould material is oxidized easily, and high thermal resistance is poor, does not reach preventive effect.On the mould material of above-mentioned aluminium silicon, improve; Adopt silicon carbide castable; Be specially on the mould material surface and form silica membrane, but silicon-carbide particle changes time, high thermal resistance, film forming speed that the meeting influence forms silica membrane, so the ratio that the particle diameter of silicon carbide castable and different-grain diameter add; Removing the composition of other additives of silit, is to form the emphasis that silicon carbide castable guarantees resistive connection skin, high-strength wearable.
Summary of the invention
The present invention provides anti-blocking mould material of a kind of silicon carbide crusting resistant and preparation method thereof, and it is not good to have solved existing silicon carbide castable film forming speed, and make the matter of this mould material itself hard, alkaline-resisting, thermal shock resistance is more excellent.
The present invention realizes through following technical scheme:
The anti-blocking mould material of a kind of silicon carbide crusting resistant is that the material by following mass fraction mixes: 25～35 parts of the high silicon porcelain vase of 10-3mm particles, 10～15 parts of 3-1mm silicon-carbide particles, 25～35 parts of 1-0mm silicon-carbide particles, 10～15 parts of 320 order carbide fine powder, 3～6 parts of 2-10 μ m silicon carbide micro-powders, 5～8 parts of cement, 5.5～6.5 parts in water, 4～6 parts of inhibitors, 0.1～0.2 part of cement water reducing agent.
Said cement is high-alumina cement.
Said inhibitor is a SILICA FUME, and said SILICA FUME particle diameter D50 is 0.8 μ m.
Said cement water reducing agent is sodium formaldehyde condensation products (NF).
The present invention reaches the purpose that improves film forming speed through the silit and different additions of above-mentioned different-grain diameter.
The present invention also provides the preparation method of the anti-blocking mould material of this silicon carbide crusting resistant.
The preparation method of the anti-blocking mould material of a kind of silicon carbide crusting resistant; Behind above-mentioned other raw material proportional mixing except that raw water, after the brickwork scene adds water and mixes, add vibration compacting in the die cavity; After conventional maintenance baking, can use; Said conventional maintenance baking was meant after the hardened material demoulding maintenance 20～25 hours, was warmed up to 150 ℃ with the heat-up rate of 25 ℃/h, was incubated 12 hours; Heat-up rate with 25 ℃/h is warmed up to 350 ℃ again, is incubated 12 hours; Heat-up rate with 25 ℃/h is warmed up to 600 ℃ again, is incubated 6 hours; Heat-up rate with 50 ℃/h is warmed up to use temperature again, comes into operation.
Beneficial effect of the present invention is:
1, improves the film forming speed that existing silicon carbide castable forms silica membrane;
2, make the matter of this mould material itself hard, alkaline-resisting, thermal shock resistance is more excellent.
