A kind of cement preheater castable refractory composite inner barrel.With high-strength wearable alkali resistant castable refractory as primary raw material, and the structural framework made of heat resisting steel carries out pouring into a mould the monomer lacing film of composite setting, is combined into the cement preheater inner core of rounded cylindrical structure by monomer lacing film by fixing locking plate connection.
Description
Art
The present invention relates to a kind of novel concrete production line preheater inner barrel, is the replacement of heat resisting steel form preheater inner barrel
Product, especially wear-resisting, high temperature resistant, decay resistance are higher than traditional heat-resisting steel inner cylinder.
Background technology
Since entering 21 century, new type nonaqueous cement industry fast development, but the preheater inner barrel of these production lines is extremely
The modern overwhelming majority adopts heat-resisting steel making, it is well known that 3 grades of cement kiln preheaters, 4 grades, 5 grades of inner core, stand for a long time
, while there is the substantial amounts of harmful components gas such as acid, alkaline in the washing away of 500 900 DEG C of high temperature and high material concentration air-flow
Corrode, and heat-resisting steel part be although high temperature resistant, mechanical strength properties are good, but the tolerance level to harmful components gas pickling is bad,
Particularly at high temperature this erosion and wash away and can aggravate significantly, so that the heat-resisting steel inner cylinder lacing film of preheater is usually deformed or
Breaking releasing, causes putty and is forced to stop kiln repairing, the security incident for easily occurring high-temperature material to hurt sb.'s feelings during repairing；Generally, resistance to
Hot steel inner cylinder its make life-span also only left and right one year, fee of material and maintenance cost high, burst accident direct losses and indirect loss are big；
The traditional heat-resisting steel inner cylinder of preheater consumes the rare metals such as national substantial amounts of chromium, nickel and the manufacture energy.
Content of the invention
In order to overcome the shortcomings of that the traditional heat-resisting steel inner cylinder usage cycles of cement preheater are short and cost price is high, the present invention
Adopt using castable refractory as primary raw material and a small amount of heat resisting steel is shaped by particular manufacturing craft as skeleton, cast is complex as strip
The monomer lacing film of shape, is combined into the cement preheater inner core of rounded cylindrical structure by the connection of monomer lacing film.The present invention can be substituted
The pure heat-resisting steel inner cylinder of traditional cement preheater, heat-resisting steel inner cylinder pure with cement preheater are compared, and heat resisting steel consumption reduces five points
More than four, make manufacturing cost reduce, greatly save national rare metal resources and energy resource consumption；Due to adopting castable refractory
Mutually it is combined with heat resisting steel, the present invention possesses that high temperature resistant, wear-resistant, intensity is high, corrosion resistant characteristic, and traditional cement preheater
Pure heat-resisting steel inner cylinder is compared, have the characteristics that stability height, usage cycles length, convenient to install and maintain.
The technical solution adopted for the present invention to solve the technical problems：
1st, structure design
Present invention heat resisting steel is fabricated to " cage " type structural framework, and there is hanged hook on top, with particular manufacturing craft to whole " cage "
Type skeleton is shaped, and pours into a mould castable refractory after sizing, and castable and heat-resisting steel skeleton are combined into monomer lacing film, are shaped as strip
Shape, monomer lacing film is by hanged hook and the inner core of the circular tubular structure of base combination.The design principle of monomer lacing film is：" cage "
The heat-resisting steel structure framework of type can increase the mechanical strength of inner core lacing film, and the heat-resisting reinforcing bar structural framework of " cage " type is by special
Mould shape, and castable refractory be complex as one overall, the castable after sizing in use can effective protection heat resisting steel from
The erosion that washes away with pernicious gas of dust, extends the service life of the present invention；Monomer lacing film is connected by hanged hook and pedestal
Circular inner core, is attached by heat resisting steel fixed link plate and lacing film fixed hook between adjacent lacing film, and principle is：Increase this
Steadiness of the invention in use environment, reduces and injures because of the vibrations that environmental factor is caused.
Wall thickness of the present invention is 80mm, and internal diameter and height require design according to user, and monomer lacing film quantity can be by inner core
Perimeter dimension is divided into 36 pieces, 72 pieces or 144 pieces.
2nd, raw material selection
Castable refractory type selecting used by main body lacing film of the present invention is：High-strength wearable Alkali-resistant castable refractory, after sizing
The use of temperature it is 1500 DEG C；Heat resisting steel used from the trade mark is：06Cr25Ni20, is more than 1100 DEG C using temperature.According to high-strength
Wear-resisting alkali resistant castable has that high temperature resistant, wear-resistant, hardness is high, corrosion resistant premium properties and the 06Cr25Ni20 trade mark heat-resisting
Steel has high mechanical strength, resistant to elevated temperatures feature, the present invention (maximum temperature is less than 1000 DEG C) stable performance in use environment,
The performance indications such as wherein wear-resisting, high temperature resistant, resistant to corrosion are better than the inner core with heat-resisting steel making.
The invention has the beneficial effects as follows：The advantage of castable and heat resisting steel is compounded with, its integrated performance index exceedes tradition
Heat-resisting steel inner cylinder；Usage cycles are long, and user's production cost reduces, and overhaul convenient and safe；Rare metal resources are saved for country.
