Abstract
The invention relates to the technical field of steel and provides a pre-heater rotary barrel air barrel inner barrel provided with an ultra-strong heat resistant steel belt. The pre-heater rotary barrel air barrel inner barrel comprises an inner barrel body connected with a cyclone barrel fixing seat, wherein the inner barrel body is formed by mutually matching and connecting multiple ceramic hanging pieces with two-layer or three-layer or four-layer or five-layer layered structures and ceramic connecting plates. The pre-heater rotary barrel air barrel inner barrel is characterized in that each ceramic hanging piece is of a square plate block structure, reverse symmetric embedding steps are respectively arranged on the left side face and the right side face of each ceramic hanging piece, every two ceramic hanging pieces are embedded in a left-right mode, the ceramic hanging pieces are tightly arranged in the peripheral direction to form a barrel-shaped body, and through holes penetrating through the front surface and the rear surface are respectively formed in the upper end portions and the lower end portions of the front surface and the rear surface of each ceramic hanging piece. The invention aims at providing a heat-resistant abrasion-resistant steel plate and a manufacturing method thereof. On the basis that a proper number of alloy elements are added, the heat-resistant abrasion-resistant steel plate still has better hardness and abrasion resistance at higher temperature, and wide application of the heat-resistant abrasion-resistant steel plate in various projects under high-temperature condition is facilitated.
Description
Technical field
The present invention relates to iron and steel domain, particularly relate to a kind of preheater with ultra-strong refractory steel steel band and revolve an air duct inner core.
Background technology
For a long time, the internal barrel of preheater cyclone barrel applied in domestic and international dry cement production line, material is based on kuromore steel, its outstanding shortcoming is present in two aspects: one is that the price comparison of steel is expensive, per ton usually all more than 100,000 yuan, produce an internal barrel of preheater cyclone barrel cost like this and will reach hundreds of thousands unit; Two is that physical life is shorter, the acid-alkali-corrosive-resisting poor-performing of steel alloy, and under normal state, the life-span on average only has 10-14 month.Change inner core based on this shut-down (breakdown) mainteance caused, had a strong impact on the production time of enterprise, caused burden to enterprise's production cost.How to manufacture one and have high strength, the inner core of anticorrosive anti-wear performance is to substitute existing steel alloy, and production control cost simultaneously, improves physical life, is the technical problem that manufacture of cement industry is paid close attention to.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, proposing a kind of preheater with ultra-strong refractory steel steel band and revolving an air duct inner core.
Scheme of the invention of the present invention is: the present invention proposes a kind of preheater with ultra-strong refractory steel steel band and revolve an air duct inner core, it is characterized in that, comprise the inner barrel be connected with cyclone cylinder holder, described inner barrel by setting up and down be that the polylith pottery lacing film of two layers or three layers or four layers or five laminate and ceramic joining plate mutually mate and connect and compose; It is characterized in that, ceramic lacing film described in every block is square plate structure, about it, two sides are respectively arranged with the chimeric step of reverse symmetry, between ceramic lacing film, left and right is chimeric between two, and circumferentially close-packed arrays forms cylindrical body, the upper end on the described forward and backward surface of ceramic lacing film and bottom are respectively arranged with the through hole of through front and rear surfaces.
The present invention possesses following beneficial effect: the present invention compares with similar heat resisting steel product and can improve service life 1-3 times, 5%-15% low with same type of material cost, can use continuously in high temperature environments, there is good thermal fatigue resistance and resistance to elevated temperatures, Reusability not easily produces decrepitation, uses maximum temperature can reach more than 1400 DEG C.
Detailed description of the invention
For making the technical problem to be solved in the present invention, technical scheme and advantage clearly, be described in detail below in conjunction with specific embodiment.
Scheme of the invention of the present invention is: the present invention proposes a kind of preheater with ultra-strong refractory steel steel band and revolve an air duct inner core, it is characterized in that, comprise the inner barrel be connected with cyclone cylinder holder, described inner barrel by setting up and down be that the polylith pottery lacing film of two layers or three layers or four layers or five laminate and ceramic joining plate mutually mate and connect and compose; It is characterized in that, ceramic lacing film described in every block is square plate structure, about it, two sides are respectively arranged with the chimeric step of reverse symmetry, between ceramic lacing film, left and right is chimeric between two, and circumferentially close-packed arrays forms cylindrical body, the upper end on the described forward and backward surface of ceramic lacing film and bottom are respectively arranged with the through hole of through front and rear surfaces.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from principle of the present invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
