Abstract
The utility model discloses a low-alumina cement gunning mix. The gunning mix is characterized in that the gunning mix is a spherical filler and is divided into three layers; the inner layer is formed by aluminous cement castables; the middle layer is a refractory layer; and the outermost layer is a wear layer. The gunning mix has the advantages of high refractoriness, good thermal shock resistance and stability and strong wear resistance, greatly prolongs the service lives of products, and simultaneously reduces the maintenance cost.
Description
Technical field
The utility model belongs to fire resisting material field, is specifically related to the low cement jetting material of a kind of aluminium oxide.
Background technology
Along with the fast development of China's building materials industry, the demand of cement increases day by day, and on the cement dry method production line that maximizes, the refractory material at coal powder injection pipe and kilneye place is crucial, and is most important to the normal operation continuously of cement kiln.From the external a complete set of cement kiln equipment of introducing, coal powder injection pipe position water material feeding, service life is also very short.
Coal powder injection pipe position work under bad environment, also harsh to the requirement of refractory material, not only require high temperature resistant and good thermal shock resistance, and exigent mechanical strength and wearability, and otherwise stop up the outlet of coal powder injection pipe.The material feeding of watering of the common coal powder injection mouth of pipe does not have solid shape, for one deck is layered on kilneye or a corral in the material feeding of watering of the mouth of pipe, if directly one deck is layered on kilneye, be easy to cause coal powder injection pipe place not have anti-material to cover, influence kiln temperature, brought the decline of operating efficiency, even can cause potential safety hazard; If directly be trapped among the coal powder injection mouth of pipe, owing to the no solid form reason of watering material feeding, stop up the mouth of pipe easily and cause coal powder injection insufficient, prolonged the working time, improved the cost of work.
Summary of the invention
Goal of the invention: the purpose of this utility model is at the deficiencies in the prior art, provides a kind of aluminium oxide to hang down the cement jetting material.
Technical scheme: in order to reach the foregoing invention purpose, the utility model specifically is achieved like this: a kind of aluminium oxide hangs down the cement jetting material, it is characterized in that, be ball filler, divide 3 layers, internal layer is aluminium matter cement deposit material, the intermediate layer is flame retardant coating, and outermost layer is wearing layer.
Wherein, described flame retardant coating is fire-resistant asbestos.
Wherein, described wearing layer is steel fibre.
Wherein, be filled with the PVC adhesive between described flame retardant coating and the wearing layer.
Beneficial effect: the utility model compared with prior art, refractoriness height, anti-thermal shock, good stability, wear-resisting by force in the service life of having improved product greatly, have reduced maintenance cost simultaneously.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
The specific embodiment
The low cement jetting material of aluminium oxide is ball filler as shown in drawings, divides 3 layers, internal layer is aluminium matter cement deposit material 1, and the intermediate layer is flame retardant coating 2, and outermost layer is wearing layer 3, described flame retardant coating 2 is fire-resistant asbestos, and wearing layer 3 is steel fibre, is filled with the PVC adhesive between flame retardant coating 2 and the wearing layer 3.
Certainly, the above only is specific embodiment of the utility model, be not to limit scope of the present utility model, all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
