Abstract
The invention aims to provide a castable specially used for coal-injection ducts of cement kilns. By adopting the castable, the problem of non-uniformity of tissue structures of current castables can be solved, the defects of poor constructability and castable segregation, more pores and non-uniformity of pore distribution caused by poor constructability are overcome, the phenomena of no wear resistance, spalling, no erosion resistance, and the like of kiln mouths can be effectively improved, and the service lives of the mouths of the cement kilns can be substantially prolonged.
Description
Technical field
The present invention relates to building materials high-temperature material field, be specifically related to a kind of cement kiln coal injection pipe dedicated pouring material.
Background technology
Rapidly, cement production capacity is seriously superfluous for the new type nonaqueous cement production line development of current China.Therefore, cement production enterprise improves production of units efficiency, and reducing production cost, is generate profit maximized only way.And the operation factor improving cement producing line is the essential condition improving cement kiln production efficiency.But there is important impact the running period of the life-span of cement kiln coal injection pipe on whole production line.The coal injection pipe working conditions of cement kiln is severe, except bearing up to except high temperature in 1400 DEG C of kilns, also bear washing away of cement kiln clinker, the thermal stresses that the secondary air that grate-cooler comes causes, chlor-alkali corrodes the impact brought it, thus has higher requirement to the over-all properties of the mould material that cement kiln coal injection pipe uses.3 to 8 months work-ing life of current common coal injection pipe, not etc. such life-span still can not meet the demand of client.The major cause affecting its work-ing life is that current refractory castable wears no resistance, poor heat stability, properties is unstable, simultaneously the chemical erosion of cement kiln coal injection pipe also not water resistant mud kiln atmosphere, constrain the raising of cement kiln production line rate, have impact on the economic benefit of cement producer.
In addition, the shortcomings such as current coal injection pipe castable exists the defect of workability difference, and easily cause mould material segregation, pore is many, and gas cell distribution is uneven, thus also reduce the work-ing life of coal injection pipe.
Summary of the invention
The object of this invention is to provide a kind of coal injection pipe castable, the mould material segregation solving application property difference and come by application property difference band, pore is many, the defect that gas cell distribution is uneven.By above-mentioned measure, effectively can improve the not wear-resisting of coal injection pipe, fall block, the phenomenon such as anti-erosion, significantly can not extend the coal injection pipe work-ing life of cement kiln.
