Abstract
A kind of combined type grate preheating section side wall refractory material laying structure of the present utility model, including grate side wall steel plate, the calcium silicate board with microporous being fixedly connected with this grate side wall steel plate, heavy castable, anchored brick and extension brick part, it is characterised in that：The extension brick part termination spliced eye welded in grate side wall steel plate, described calcium silicate board with microporous is adhered on grate side wall steel plate inwall with clay fire-resistant slurry, and leave the position for hanging brick part termination spliced eye, being built between calcium silicate board with microporous and heavy castable has lightweight clay brick, anchored brick is arranged between lightweight clay brick and heavy castable, described extension brick part one end is connected with the termination of anchored brick, and the other end, which is plugged on, to be hung in the spliced eye of brick part termination.Three kinds of calcium silicate board with microporous, lightweight clay brick and heavy castable materials are organically combined into an entirety by the utility model, further increasing the service life of side wall refractory material.
Description
Technical field
The utility model belongs to pellet production technical field, more particularly, to a kind of combined type grate preheating section side wall
Refractory material laying structure.
Background technology
With the fast development of China " chain-kiln " pelletizing process production acid pellet, this technique is progressively recognized by industry
Can, grate hot blast system normal operation is related to the operating rate of the entire production line.Grate preheating section is divided into I, two sections of II, in advance
Temperature is 700 DEG C or so in hot I sections, and it is 1000 DEG C or so to preheat temperature in II sections.II sections front end is particularly preheated close to revolution
The region of kiln, it is that high-temperature flue gas washes away most severe place, so the wearability of refractory material, heat insulating ability just seem very heavy
Will.The refractory material of conventional preheating section side wall has two kinds to build form by laying bricks or stones, and one kind is lightening casting material（Heat-insulation layer）Poured into a mould with heavy
Material（Wearing layer）The compound masonry construction constructed together.The shortcomings that this masonry construction is lightening casting material and heavy cast
Expect that the coefficient of thermal expansion of two kinds of materials is different, during high temperature production, two kinds of materials are different by thermogenetic swell increment, can make
The anchored brick of anchorage effect is played in two kinds of materials by different shearing forces, causes anchored brick to be cut, scene has been sent out
Gave birth to such case；Another way is to substitute lightening casting material with double-deck calcium silicate board with microporous to have good as heat-insulation layer, calcium silicate board with microporous
Heat-insulating property, swell increment is small under high temperature.In process of production, do not have anchored brick occur to be sheared disconnected situation.But this
Kind, which builds form by laying bricks or stones, also shortcoming, and heavy castable produce many holes in the stage of building by laying bricks or stones, meeting inside castable.In these holes
In, some holes run through whole heavy castable thickness, cause in process of production high-temperature flue gas pass through hole direct baking
Calcium silicate board with microporous, cause calcium silicate board with microporous carbonization, rupture, influence normally to produce.
The content of the invention
The purpose of this utility model is to provide a kind of easy for construction, and baker is simple, good heat preservation performance, and side wall refractory material uses
Life-span longer combined type grate preheating section side wall refractory material laying structure.
The purpose of this utility model is achieved through the following technical solutions：
A kind of combined type grate preheating section side wall refractory material laying structure of the present utility model, including grate side wall
Steel plate, the calcium silicate board with microporous being fixedly connected with this grate side wall steel plate, heavy castable, anchored brick and extension brick part, it is characterised in that：
The extension brick part termination spliced eye welded in grate side wall steel plate, described calcium silicate board with microporous adhere to chain grate with clay fire-resistant slurry
On machine side wall steel plate inwall, and the position for hanging brick part termination spliced eye is left, being built between calcium silicate board with microporous and heavy castable has gently
Matter clay brick, anchored brick are arranged between lightweight clay brick and heavy castable, and described hangs brick part one end and the end of anchored brick
Head is connected, and the other end, which is plugged on, to be hung in the spliced eye of brick part termination.
The utility model has the advantages that：
（1）One layer of calcium silicate board with microporous that the utility model remains former grate side wall in original is strong as heat-insulation layer, its calcium silicate board with microporous
Relatively low, easily cutting is spent, it is easy for construction.Calcium silicate board with microporous thermal conductivity factor itself is small, can play good insulation effect；
（2）Because heavy casting material strength is high, anti-wear performance is good, can be very good to resist washing away for high-temperature flue gas, therefore
Wearing layer still selects heavy castable；
（3）One layer of lightweight clay brick is set up between calcium silicate board with microporous and heavy castable, that is, serves as heat-insulation layer, can play again
The effect of calcium silicate board with microporous is protected, while the intensity of lightweight clay brick in itself can also ensure that high-temperature flue gas washes away calcium silicate board with microporous well；
Other lightweight clay brick is burns till product, and quick construction is conveniently.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of combined type grate preheating section side wall refractory material laying structure, including grate side wall steel
Plate 1, the calcium silicate board with microporous 2 being fixedly connected with this grate side wall steel plate 1, heavy castable 7, anchored brick 6 and extension brick part 4, its feature
It is：The extension brick part termination spliced eye 5 welded in grate side wall steel plate 1, the described clay fire-resistant slurry of calcium silicate board with microporous 2
Adhere on the inwall of grate side wall steel plate 1, and leave the position for hanging brick part termination spliced eye 5, in calcium silicate board with microporous 2 and heavy castable
Being built between 7 has lightweight clay brick 3, and anchored brick 6 is arranged between lightweight clay brick 3 and heavy castable 7, described extension brick part 4
One end is connected with the termination of anchored brick 6, and the other end, which is plugged on, to be hung in brick part termination spliced eye 5.
7 three kinds of calcium silicate board with microporous 2, lightweight clay brick 3 and heavy castable materials are organically combined into one by the utility model
It is overall, it further increasing the service life of side wall refractory material.
