Abstract
The object of this invention is to provide a kind of 12000T cement kiln coal injection pipe dedicated pouring material, its institutional framework that can improve current castable existence is inhomogeneous, and having solved application property castable segregation poor and that come by application property difference band, pore is many, the defect that gas cell distribution is inhomogeneous. By above-mentioned measure, can effectively improve the not wear-resisting of kilneye, fall piece, the not phenomenon such as anti-erosion, can significantly extend kilneye service life of cement kiln.
Description
Technical field
The present invention relates to building materials and use high-temperature material field, be specifically related to a kind of 12000T cement kiln coal injection pipe dedicated pouring material.
Background technology
Rapidly, cement production capacity is seriously superfluous in China's new type nonaqueous cement production line development at present. Therefore, cement production enterprise improves production of units efficiency, reduce production costs, and be to generate profit maximized only way. And the running rate that improves cement producing line is the essential condition that improves cement kiln production efficiency. But the life-span of cement kiln coal injection pipe is on there being important impact the service cycle of whole production line. The coal injection pipe service condition of cement kiln is severe, except bearing up to high temperature in 1400 DEG C of kilns, also bear washing away of cement kiln clinker, the thermal stress that the Secondary Air that grate-cooler comes causes, chlor-alkali corrodes the impact that it is brought, thereby the combination property of the castable that cement kiln coal injection pipe is used is had higher requirement. The service life 3 of current common coal injection pipe, by 8 months etc. such life-span still can not meet client's demand. The main cause that affects its service life is that current castable refractory is not wear-resisting, not anti-strip, thermal shock resistance is poor etc., simultaneously the also not chemical erosion of water resistant mud kiln atmosphere of cement kiln coal injection pipe, restrict the raising of cement kiln production line rate, affected the economic benefit of cement producer.
In addition the shortcoming such as current coal injection pipe castable exists the poor defect of workability, easily causes castable segregation, and pore is many, and gas cell distribution is inhomogeneous, thereby the service life of also having reduced coal injection pipe.
Summary of the invention
The object of this invention is to provide a kind of coal injection pipe castable, it has solved application property castable segregation poor and that come by application property difference band, and pore is many, the defect that gas cell distribution is inhomogeneous.

In above-described embodiment, each component used is to well known to a person skilled in the art product, on market, all can buy, and the wherein interpolation of synthetic moissanite, strontium titanates, brown corundum, steel fibre, is conducive to the wearability of castable, thermal shock resistance; Andalusite has micro-expansibility; The introducing of zirconium carbonate makes castable in use obtain good performance, zirconium carbonate is decomposed to form the oxide of high activity zirconium with superperformance, and the micropore forming in decomposable process, all be conducive to improve the thermal shock resistance of material, improve corrosion resistance, avoid the phenomenons such as castable ftractures, drops; Zinc silicate, alumina powder simultaneously, terbium oxide, in use can progressively react, and generates the good original position aluminium of performance gahnite, improves the structural homogenity of castable, improves the anti acid alkali performance energy of castable, chemical resistance of concrete performance. The Tc adding2O7, Sulfonated Copolymer of Styrene and Maleic Anhydride, polyethers polycarboxylic acids can improve the operable time of castable, the distribution of the pore while improving castable construction, mobile performance, according to temperature difference, can suitably regulate addition; The C adding5H10N6O2Produce the micro-pore being communicated with, the steam producing while making to toast is easily discharged, and the silica xerogel powder activity adding is high, is easy to aluminium oxide and generates well behaved mullite. Adopt after above-mentioned scheme, can obtain a kind of well behaved castable, extended to more than 2 times the service life of coal injection pipe prepared by castable.
The cement kiln coal injection pipe dedicated pouring material of above-described embodiment 1-4 is prepared by the following method: by each component mixing and stirring, then add appropriate water mixing strong stirring even, more then moulding is used after conventional maintenance and baking.
The physical index of above-described embodiment 1-4 relatively sees the following form:
