In a word, the utility model provides high low aluminium check brick when firing pile up put efficiency, guaranteed low aluminium check brick and fired the quality.

Description

Tool brick for firing low-aluminum grid brick

Technical Field

The utility model relates to a refractory material technical field, concretely relates to low aluminium check brick is fired and is used instrument brick.

Background

Low aluminium check brick is one kind and puts things in good order in large-scale coke oven regenerator, utilize heat accumulation in turn/exothermic porous resistant firebrick who retrieves the high temperature flue gas waste heat that the combustion chamber discharged out, the middle part of its upper surface is provided with the depressed part, when low aluminium check brick is produced, need put things in good order it and fire, traditional low aluminium check brick dress method is the dress immediately, as shown in figure 1, can only adorn 1~2 layers immediately, again high can lead to in the high temperature firing process, it is relatively poor to ventilate, phenomenons such as crackle appear in the check brick, and because the liquid phase in the low aluminium check brick composition produces and causes the brick to soften, thereby lead to the downward top of low aluminium check brick bottom plane, can cause the crackle, distortion scheduling problem causes the product to scrap.

SUMMERY OF THE UTILITY MODEL

The utility model provides a low aluminium check brick is fired and is used instrument brick, aim at: the stacking efficiency of the low-aluminum grid bricks during firing is improved, and the firing quality of the low-aluminum grid bricks is ensured.

In order to achieve the above object, the present invention provides the following technical solutions:

the utility model provides a low aluminium check brick is fired and is used instrument brick, includes the brick body of rectangular bodily form, the thickness of the brick body is higher than the depressed part degree of depth 2~3mm of low aluminium check brick, the length of the brick body equals the width of low aluminium check brick, the width of the brick body is less than the length of the depressed part of low aluminium check brick and is greater than 2/3 of the depressed part length of low aluminium check brick, still be provided with a plurality of through-holes on the brick body.

Further, the length of through-hole is greater than 2/3 of brick body length, the width of through-hole is 7~10 mm.

Compared with the prior art, the beneficial effects of the utility model are that: the traditional low-aluminum grid brick mounting method is vertical mounting. Can only adorn 1~2 layers immediately, it is all lower to pile up put efficiency and product percent of pass, average percent of pass is only 70% ~80%, adopt the utility model discloses afterwards, low aluminium checker brick can adopt the flush mounting, once pile up put can 7~8 layers of flush mounting, stability is high, and the through-hole can guarantee at the drying with burn till the in-process, dry wind and hot-blast can be through each position of the even low aluminium checker brick that passes through of through-hole, avoid low aluminium checker brick crackle and guarantee the sintering of low aluminium checker brick to appear, ensured the product percent of pass, its efficiency of piling up is 3~4 times of dress efficiency immediately, the percent of pass also promotes 92% ~95 on average, has improved the productivity effect by a wide margin. In a word, the utility model provides high low aluminium check brick when firing pile up put efficiency, guaranteed low aluminium check brick and fired the quality.

In the figure: 1. low aluminium check brick, 101, depressed part, 2, the brick body, 201, through-hole.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention.

Example (b): as shown in figures 1 to 4, the utility model provides a tool brick for firing low-aluminum checker brick, comprising a cuboid brick body 2, the thickness of the brick body 2 is 2-3 mm higher than the depth of the depressed part 101 of the low-aluminum checker brick 1, preventing the adjacent two low-aluminum checker bricks 1 from extruding and ensuring ventilation, the length of the brick body 2 is equal to the width of the low-aluminum checker brick 1, the width of the brick body 2 is less than the length of the depressed part 101 of the low-aluminum checker brick 1 and greater than 2/3 of the length of the depressed part of the low-aluminum checker brick, the brick body 2 is further provided with a plurality of through holes 201, the length of the through holes 201 is greater than 2/3 of the length of the brick body 2, the width of the through holes 201 is 7-10 mm, not only ensuring enough ventilation area, but also ensuring the strength of the brick body 2, in the drying and firing processes, dry air and hot air can uniformly pass through all positions of the low-aluminum checker brick through the through holes 201, so that cracks of the low-aluminum checker brick are avoided, and sintering of the low-aluminum checker brick is guaranteed.

The principle and the embodiment of the present invention have been explained by using specific examples, and the description of the above embodiments is only used to help understand the method and the core idea of the present invention, it should be pointed out that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and these modifications and modifications also fall into the protection scope of the claims of the present invention.
