Abstract
The invention discloses a fireproof castable composite inner drum of a cement preheater. A high-intensity, anti-abrasion, alkali-resistant and fireproof castable is used as a main raw material, and a single hanging sheet which is obtained by casting, combining and setting a structural framework prepared from heat-resistant steel is adopted; the single hanging sheets are connected and combined through fixed locking sheets to form the inner drum of the cement preheater, which is of a cylindrical structure.
Description
Art
The present invention relates to a kind of novel concrete production line preheater inner barrel, is the substitute of heat resisting steel form preheater inner barrel, and especially wear-resisting, high temperature resistant, decay resistance is higher than traditional heat resisting steel inner core.
Background technology
Since entering 21 century, new type nonaqueous cement industry fast development, but the manufacture of the preheater inner barrel of these production lines overwhelming majority employing so far heat resisting steel, as everyone knows, cement kiln preheaters 3 grades, 4 grades, the inner core of 5 grades, washing away of 500-900 DEG C of high temperature and high material concentration air-flow will be stood for a long time, there is a large amount of acidity simultaneously, the erosion of the harmful components gases such as alkalescence, and although heat resisting steel goods are high temperature resistant, mechanical strength properties is good, but it is bad to the tolerance level of harmful components gas pickling, particularly at high temperature this erosion and wash away and can greatly aggravate, preheater heat resisting steel inner core lacing film usually can be deformed or breaking releasing, cause putty and be forced to stop kiln repairing, the security incident that high-temperature material is hurted sb.'s feelings very easily is there is during repairing, usually, heat resisting steel inner core 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 large, the heat resisting steel inner core consumption a large amount of rare metal such as chromium, nickel of country that preheater is traditional and the manufacture energy.
Summary of the invention
In order to overcome the deficiency that the traditional heat resisting steel inner core life cycle of cement preheater is short and cost price is high, it is that primary raw material and a small amount of heat resisting steel are shaped by particular manufacturing craft as skeleton that the present invention adopts with castable refractory, cast is complex as the monomer lacing film of elongate in shape, is synthesized the cement preheater inner core of rounded cylindrical structure by monomer lacing film Connecting groups.The present invention can substitute the pure heat resisting steel inner core of traditional cement preheater, compares with the pure heat resisting steel inner core of cement preheater, and heat resisting steel consumption reduces more than 4/5ths, manufacturing cost is reduced, greatly saves national rare metal resources and energy resource consumption; Owing to adopting castable refractory and heat resisting steel phase compound, the present invention possess high temperature resistant, wear-resistant, intensity is high, corrosion resistant characteristic, compare with the pure heat resisting steel inner core of traditional cement preheater, have that stability is high, life cycle is long, installation and maintenance feature easily.
The technical solution adopted for the present invention to solve the technical problems:
1, structural design
The present invention's heat resisting steel is made into " cage " type structural framework, there is hanged hook on top, with particular manufacturing craft, whole " cage " type skeleton is shaped, castable refractory is poured into a mould after sizing, castable and heat resisting steel skeleton are combined into monomer lacing film, shape is elongate in shape, and monomer lacing film is by the inner core of hanged hook and the circular tubular structure of base combination.The design principle of monomer lacing film is: the heat resisting steel structural framework of " cage " type can increase the mechanical strength of inner core lacing film, the heat-resisting reinforcing bar structural framework of " cage " type is shaped by particular manufacturing craft, an entirety is complex as with castable refractory, castable after sizing in use can available protecting heat resisting steel from the erosion with pernicious gas of washing away of dust, extend service life of the present invention; Monomer lacing film connects into circular inner tube by hanged hook and pedestal, be connected with lacing film fixed hook by heat resisting steel fixed link plate between adjacent lacing film, principle is: increase the steadiness of the present invention in environment for use, reduces the vibrations injury because environmental factor causes.
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 divided into 36 pieces, 72 pieces or 144 pieces by inner core perimeter dimension.
2, raw material selection
Main body lacing film of the present invention castable refractory type selecting used is: high-strength wearable Alkali-resistant castable refractory, and the serviceability temperature after sizing is 1500 DEG C; Heat resisting steel used selects the trade mark to be: 06Cr25Ni20, serviceability temperature is greater than 1100 DEG C.According to high-strength wearable alkali resistant castable have high temperature resistant, wear-resistant, hardness is high, the heat resisting steel of corrosion resistant premium properties and the 06Cr25Ni20 trade mark has high, the resistant to elevated temperatures feature of mechanical strength, the present invention is (maximum temperature is less than 1000 DEG C) stable performance in environment for use, and wherein the performance indications such as wear-resisting, high temperature resistant, resistant to corrosion are better than the inner core manufactured with heat resisting steel.
The invention has the beneficial effects as follows: the advantage being compounded with castable and heat resisting steel, its integrated performance index exceedes traditional heat resisting steel inner core; Life cycle is long, and user's production cost reduces, and overhauls convenient and safe; For country saves rare metal resources.
