Abstract
The invention discloses a castable used for an industrial furnace lining and a producing process thereof, and particularly relates to a quick-drying explosion-proof castable used for an industrial furnace lining and a producing process thereof. The producing process comprises four steps of raw material purchasing and testing, burdening, mixing and packaging. The producing process of the invention has the advantages of realizing quick-drying (rapid hardening) and fast stripping of the castable, and rapid baking without burst or explosion. With greatly shortened construction time and baking time, production pace is speeded up, a large quantity of energy is saved, emission of carbon dioxide and nitrogen oxide is significantly reduced and economic and social benefits are prominent.
Description
Technical field
The present invention relates to a kind of quick-drying anti-explosion mould material and production technique thereof, belong to technical field of refractory materials.
Background technology
Low cement deposit material (LCC) and ultra-low cement deposit material (ULCC) are used widely on Industrial Stoves such as process furnace, soaking pit, stoving oven, limestone kiln, rotary kiln, producer gas generator, heat treatment furnace owing to have HS, high-wearing feature, high resistance of heat shocks and excellent advantages such as resistance to fouling.
Secular in service at these Industrial Stoves, because effects such as airflow scouring, flue gas corrosion and mechanical wears, refractorily lined can be damaged.Be to improve the comprehensive work-ing life of furnace lining, need to stop production in good time, with mould material to furnace lining carry out light maintenance, in repair and overhaul.When the damage degree greatly when being difficult to repair or do not have the value of repairing, just need the integral replacing furnace lining.Generally, mould material natural curing demoulding after a day, natural air drying toasts two days later.Yet; The low porosity of mould material and the characteristics of high-compactness have caused the ventilation property of material own poor; Cause the water vapor that in bake process, produces to be difficult to smooth and easy, discharge timely; When vapor pressure surpass material self bear the limit time, furnace lining just can crack, peels off even burst, the generation of for this reason taking the measure of long-time (5~8 days) baker to prevent to burst usually.Obviously, this runs counter to the fast paceization of the desired Production Flow Chart of modern enterprise, and in addition, long-time baking also can waste energy, and causes serious economy loss.
Summary of the invention
For addressing the above problem; The present invention aims to provide a kind of quick-drying anti-explosion mould material and production technique thereof, can when Industrial Stoves sectional repair or integral replacing furnace lining, realize fast demoulding and quick baking; Thereby shorten brickwork, storing time, guarantee to produce and carry out quickly and safely.
For realizing above-mentioned purpose, the technical scheme that the present invention takes is: in mould material, add efficient setting accelerator Quilonum Retard and Lithium chloride (anhydrous), mould material is hardened rapidly in the time of weak point after construction, and produce enough demoulding strengths, realize fast demoulding; In mould material, add the detonation suppressor metallic aluminium powder, on the one hand, the reaction heat of metallic aluminium powder and water has strengthened demoulding strength; Improved the bursting strength limit; On the other hand, the slow effusion of reaction product hydrogen impels the inner little pore of equally distributed opening that forms of mould material, like this; In bake process, water vapour just can be discharged more smoothly; In mould material, add low-melting explosion-proof fiber, under lower storing temperature, this fiber promptly begins to soften, shrinks, melt, the small network pore of formation in the body of constructing, and its vapour passage of fetching boiling water alleviates internal stress, prevents explosion.
