Abstract
The invention discloses a novel castable refractory material with excellent wear, alkali erosion and flushing resistance, in particular to a preparation method for the castable refractory material with wear, alkali erosion and flushing resistance. The wear resistance of the castable refractory material with wear, alkali erosion and flushing resistance is lower than 3.5/cm<3> after being subjected to calcination at 1,100 DEG C for three hours, while the alkali resistance reaches first to second level. The novel castable refractory is used at a tertiary air tube elbow, an air valve, a grate cooler throat, a low wall and other positions of a large cement kiln. Compared with the prior castable refractory material, the novel castable refractory material has good wear resistance and excellent alkali erosion resistance and can greatly improve the operation rate of the cement kiln.
Description
Affiliated technical field
The present invention relates to a kind of preparation method of refractory castable, specifically, relate in a kind of new type nonaqueous cement kiln preparation method as wear, alkali resistant castable refractory material.
Background technology
From the nineties later stage in last century till now, the new type nonaqueous cement of China has obtained huge development, particularly large-scale new type nonaqueous cement kiln, as the new dry cement production technology equipment of producing 10000 tons of 5000 tons, daily output daily is reached advanced world standards substantially.China has become world cement manufacturing center, and domestic existing daily output at present surpasses 2500 ton large-scale dry-process cement rotary kiln production lines and exceeded more than 400.
Large-scale new type nonaqueous cement kiln tertiary-air pipe elbow, air-valve position are subjected to carrying the washing away of high-speed and high-temperature air-flow of a large amount of cement clinker dust, cooling machine throat, parapet are subjected to the long-term grinding of a large amount of grogs, the refractory castable at these positions is serious wear usually, and its life-span is often very low.Simultaneously, the use of hard coal, low grade coal and the burning of solid waste cause compositions such as alkali, chlorine, sulphur obviously to increase, and their circulation enrichment is to the also obviously aggravation of erosion of the refractory materials at each position of kiln system.Tertiary-air pipe elbow, air-valve position, comb
Table 1 uses the mould material performance relatively at present
Cold machine throat, these positions of parapet form alkali cracking after being corroded by compositions such as alkali, chlorine, sulphur, and its wear resisting property is extremely acute to descend, fallen by sweep of gases soon, its life cycle needs often to repair or change, influence the ordinary production of cement kiln, the short normal operation that influences kiln.Want to prolong the work-ing life at these positions, must improve the correlated performance of this position refractory castable, to adapt to the cement production process requirement.Traditional alkaline-resisting mould material, high alumina castable and corundum castable can not satisfy service requirements (its physicals sees Table 1), so should improve the wear resisting property and the alkaline resistance properties of refractory castable.
Summary of the invention
The purpose of this invention is to provide a kind of novel refractory castable, i.e. a kind of preparation method of wear, alkali resistant castable refractory material with wear resistance, alkaline-resisting aggressiveness, abrasion resistance excellence.
The preparation method who realizes wear, alkali resistant castable refractory material of the present invention is made up of proportioning raw materials and manufacture craft.
The proportioning raw materials of wear, alkali resistant castable refractory material of the present invention is pressed column weight amount % preparation:
Superfine aluminite granularity 5-3mm 15-20%;

Wear, alkali resistant castable refractory material manufacture craft of the present invention is:
Premix is made in pre-mixing in mixer with tripoly phosphate sodium STPP and pure calcium aluminate cement earlier, in mixer, the superfine aluminite of each granularity, silicon carbide, fused quartz, ultrafine silica powder, high alumina micro mist, Calcined polishing aluminum oxide micro mist, superfine flint clay micro mist and premix are mixed again, with the mould material bag distribution packaging that mixes.In the job location, add water with forced stirrer and stir, with expecting into mould or position to be cast of stirring, maintenance can be carried out baking processing after 48 hours.
Its 1100 ℃ of wear, alkali resistant castable refractory materials of the present invention burn that wear resistance is lower than 3.5/cm after back 3 hours
3, alkali resistance reaches one to secondary, has wear resistance, alkaline-resisting aggressiveness, abrasion resistance.At positions such as large-size cement kiln tertiary-air pipe elbow, air-valve, cooling machine throat, parapets, to compare with the refractory materials of present use, its wear resistance is good, has excellent alkaline-resisting aggressiveness simultaneously, can improve the cement kiln operation factor greatly.
