Abstract
The invention discloses a 12000 T/D kiln outlet special-use castable and belongs to the field of fireproofing materials. The castable inclues the components, by weight, 15-25% of mullite, 10-20% of sillimanite, 25-30% of tabular corundum, 5-10% of strontium titanate powder, 5-8% of zirconium dioxide powder, 1-3% of zinc-aluminium spinel powder, 3-5% of boron nitride, 5-10% of aluminum oxide micro powder, 4-6% of pure calcium aluminate cement, 0.2% of polylactic acid fibers, 0.1% of sodium hexametaphosphate, 0.1% of leucite and 0.1% of C12H14N4O5S2. The castable is improved in thermal shock resistance, high-temperature resistance, volume stability and wear resistance, is high in strength, is improved in the defects that a kiln outlet is not wear-resistant and is poor in thermal shock resistance, and can prolong the service life of a kiln outlet of a cement kiln from about 10 months to 2 years and more.
Description
Technical field
The present invention relates to building materials high-temperature material field, be specifically related to a kind of cement kiln outlet dedicated pouring material.
Background technology
Rapidly, within 2013, cement production capacity has broken through 2,100,000,000 tons to the new type nonaqueous cement production line development of current China, and cement production capacity is seriously superfluous.Therefore, how cement company boosts productivity, and generates profit the only way that maximization is market competition.The operation factor improving cement producing line improves cement kiln production efficiency, the essential condition of earning economic benefit.But because cement kiln bears the effect of higher temperature, violent temperature variation, strong chemical erosion and harsh mechanical stress, new type nonaqueous cement production line needs the refractory materials of excellent properties more.
The kilneye working conditions of cement kiln is severe, except being subject to up to except 1300-1400 DEG C of high temperature, the impact of the thermal stresses that the secondary air of also bearing cement kiln clinker continuous discharge and grate-cooler causes and rotary kiln rotary machine stress etc., and there is conclusive impact the running period of the life-span of cement kilneye on whole production line.Thus the mould material that cement kilneye uses is had higher requirement: high-wearing feature, highly heatproof and shockproof and high strength.Kilneye mould material develops into add by the high-strength mould material of traditional high alumina the high-performance Low Cement Castable that super-fine powder and high efficiency water reducing agent are feature, existing corundum-spinel castable (as patent CN101407424A), the Low Cement Castable such as corundum-mullite castable (as patent CN101445379B), although improve the overall use properties of mould material, make extend to about 10 months by 4-6 month of traditional high-strength mould material of use high alumina the work-ing life of kilneye, extend the cement kiln outlet life-span, but still can not meet customer need, especially at the cement kiln that some environments for use are more severe, current kilneye mould material is not wear-resisting, easily peel off, seriously constrain the raising of cement kiln production line rate, affect the economic benefit of the cement mill man that knows clearly.
Summary of the invention
The object of the invention is effectively to improve the not wear-resisting of kilneye, falls the generation of the phenomenons such as block, provides one to have resistance to
High temperature, wear-resisting, acid and alkali-resistance, high-strength, anti-thermal shock, the Special castable for kiln outlet that can greatly extend cement kiln outlet work-ing life.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs: a kind of 12000T/D Special castable for kiln outlet, and it comprises the component of following weight percentage:
