Abstract
The utility model discloses a tertiary air regulating gate plate of a rotary kiln. The tertiary air regulating gate plate is molded by taking silicon mullite bricks as a working surface and taking high-strength refractory castables as aggregates. The silicon mullite bricks serve as the working surface, the high-strength refractory castables serve as the aggregates, heat-resistant steel reinforcements form a cage type framework, and the tertiary air regulating gate plate is formed by molding and casting.
Description
Affiliated technical field
The utility model relates to a kind of novel concrete production line rotary kiln tertiary-air pipe volume adjusting apparatus, is the substitute of indefinite form pouring fireproof material device, has the performance of high-strength wearable and easy construction.
Background technology
Along with novel concrete industry fast development and technological process become better and approaching perfection day by day, cement producing line energy-saving and cost-reducing becomes pursuing one's goal of enterprise, and wherein the utilization of three hot blasts of rotary kiln becomes technological operation and economizes on coal one of the indispensable measure that lowers consumption; But; It is by the amorphous refractory moulding by casting that traditional tertiary air quantity is regulated flashboard, because it receives washing away of high temperature (800 ℃-1000 ℃), high wind speed pellet and powder for a long time and weares and teares, the refractory material at these positions is easy to lose efficacy because of excessively washing away and wearing and tearing; General service life is in 6 months; Even shorter, thus cause and the nonsynchronous phenomenon of On-Line Planning property maintenance, influence the stable of production-line technique operation; The heat-resisting steel material consumption is more simultaneously, and product cost is high.
Summary of the invention
Regulate in order to overcome novel concrete production line rotary kiln tertiary air quantity that flashboard receives for a long time that the high strength of high temperature pellet, powder is washed away, wearing and tearing and service time short defective; It is aggregate for the working face that facings the wind, castable refractory that the utility model adopts wear-resisting siliceous mullite brick, molding cast, maintenance on heat-resisting framework of steel reinforcement, dry by the fire in etc. the operation one-shot forming.The utlity model has long, the with low cost characteristics of high-wearing feature, life cycle.
The utility model solves the technical scheme that its technical problem adopted:
1, contour structures design
The utility model adopts siliceous mullite brick to be the working face that facings the wind, and the high-strength refractory pours is a wadding, and operation one-shot formings such as wadding is poured into a mould, solidified, the demoulding, maintenance, oven dry are carried out in molding on heat-resisting reinforcing bar " cage " type skeleton.Design principle is: the working face that facings the wind utilizes wear-resisting, high temperature resistant, the anti-characteristic of washing away of siliceous mullite brick, and the siliceous mullite brick end face is taked the particular design of a plurality of through holes, strengthens and the aggregate layer conjugation, gives full play to the advantage of siliceous mullite brick, satisfies the function needs.
2, raw material selection
The utility model working lining that facings the wind is selected not material type shaped brick of silicon for use, by different designs model molding typing, its refractoriness (℃) be: 1790 ℃, wearing coefficient (CC) is: 8.2-9.9; Aggregate layer is that refractory temperature is 1200 ℃ of high-strength refractory pours, and that the high-strength refractory pours has is high temperature resistant, anti-oxidant, wear-resistant, mechanical strength is high, hardness is high, the characteristics of a series of premium properties such as corrosion-resistant; Framework material selects for use the heat-resisting reinforcing bar of 0Cr25Ni20 to be welded into " cage " type structure, to increase its bulk strength.The utility model (maximum temperature is less than 1000 ℃) performance variation in environment for use is little, wherein wear-resisting, high temperature resistant, anti-erosion, anti-ly the flashboard that performance indications are superior to traditional castable refractory cast such as washes away.
The beneficial effect of the utility model is: wear-resistingly, anti-wash away, anti-erosion index surpasses the indefinite form castable refractory; Life cycle is long; Become the heat resisting steel foundry goods and be heat resisting steel reinforcing bar weldment, reduce the heat resisting steel consumption, practice thrift cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Fig. 1: siliceous mullite brick.Square structure, end face have a plurality of through holes.

The specific embodiment
In Fig. 1, siliceous mullite brick.Square structure, end face have a plurality of through holes.Adopting via design mainly is in order to increase the fastness that siliceous mullite brick and castable refractory aggregate combine, to be applied to flat face.
In Fig. 2, siliceous mullite brick.Fillet structure, end face have a plurality of through holes.Adopting via design mainly is in order to increase the fastness that siliceous mullite brick and castable refractory aggregate combine, to be applied to the arc transition face.
In Fig. 3, the heat resisting steel framework of steel reinforcement.Heat-resisting steel material, " cage " type structure.Adopting the heat-resisting steel material design mainly is to adapt to hot environment, and " cage " type structure mainly is the intensity that increases body.
Fig. 4 the utility model application implementation illustration is among the figure: make cast and location siliceous mullite brick (2) and (3) mould with heat resisting steel framework of steel reinforcement (4), pour into a mould castable refractory (1) then, carry out the demoulding, maintenance, drying forming after material feeding to be poured is solidified.
