Description

Plug-in refractory brick

Technical field

It the utility model is related to a kind of refractory material, more particularly to a kind of refractory brick.

Background technology

Industrial furnace being manufactured to burned product and carry out heat treatment process to some products, be it is a kind of not The Thermal Equipment that can or lack, industrial furnace are generally built by laying bricks or stones by the material with fire resisting and heat-insulating property and formed, and refractory brick is all kinds of The most basic refractory material of stove, as the inner lining material of stove, refractory brick will generally be resistant to the high temperature spent 1,000 more, also With preferable heat insulation effect, conventional refractory brick is rectangular parallelepiped structure, and its is simple in construction, easy to make, but is using process In, because the mutual structural relationship of such refractory brick is poor, refractory brick is by after expanding with heat and contract with cold and being influenceed, stove inner lining structure It can deform, loosen, cause gap between refractory brick to become big, be possible to directly to communicate inside and outside refractory brick, stove heat-proof quality declines, Directly affect the service life and economic benefit of stove.

Utility model content

For the above-mentioned deficiency present in prior art, technical problem to be solved in the utility model is to provide a kind of card Formula refractory brick is connect, it can strengthen the mutual structure connection of refractory brick, ensure the heat-proof quality and service life of stove.

In order to solve the above-mentioned technical problem, a kind of plug-in refractory brick of the present utility model, including refractory brick body, this is resistance to Firebrick body is the hexahedron surrounded by top surface facing each other, side and end face, is provided with the top surface of refractory brick body one Clamping groove, the bottom land linea angulata of the clamping groove is parallel with side, and the width of rebate A of the clamping groove arrives for bottom land linea angulata Two times of lateral distance B are to 2 points 5 times；Tenon is provided with refractory brick body end face, in refractory brick body other end On be provided with tongue-and-groove, the tenon is pluggable in the tongue-and-groove, and the tenon and the tongue-and-groove are parallel with top surface, and described convex Tenon and the tongue-and-groove are located at the centre position of clamping groove height.

In said structure, due to being provided with clamping groove, the groove of the clamping groove on the top surface of refractory brick body one Base angle line is parallel with side, and the width of rebate A of the clamping groove is bottom land linea angulata to two times to two points five of lateral distance B Times, then clamping groove set on the top surface of refractory brick body one is parallel with refractory brick this body side surface and in refractory brick body two It is symmetrical arranged between two parties between side, the protruding parts of both sides can be formed after such refractory brick body setting clamping groove, in reality Using when would is that two layers plug-in refractory brick relative combinations use, the protruding parts of adjacent two plug-ins refractory brick is being just in one layer Well can be so that in the clamping groove of card insertion to another plug-in refractory brick of layer one, two layers of plug-in refractory brick passes through the clamping groove Mutual clamping, mutual structural relationship are strengthened, and the stove of this spline structure is affected by thermal expansion and contraction in use When, the plug-in refractory brick of another layer of phase clamping can be to its shape after the gap increase in one layer between adjacent two plug-ins refractory brick Into barrier, prevent it from directly leading to outside, so as to ensure the heat-proof quality of stove, and the mutually plug-in fire resisting of clamping The possibility for causing stove to damage due to loosening between brick is also greatly lowered.Again due to being set on refractory brick body end face There is tenon, tongue-and-groove is provided with refractory brick body other end, the tenon is pluggable in the tongue-and-groove, then actually should Two adjacent plug-in refractory brick of end face can make structure by set tenon and the mutual clamping of tongue-and-groove in used time same layer Relevance is further strengthened, and also further ensures the thermal insulation and service life of stove.Due also to the tenon and the tenon Groove is parallel with top surface, and the tenon and the tongue-and-groove are located at the centre position of clamping groove height, then two layers it is recessed by clamping Each plug-in refractory brick upper convex tenon of the mutual clamping of groove be on same straight line with tongue-and-groove, so that by tenon and tongue-and-groove it Between the mutually plug-in refractory brick of clamping can be with Heterogeneous Permutation, structural relationship is more preferably.

A kind of preferred embodiment of the present utility model, the cross section of the clamping groove are rectangular.Using the embodiment party Formula, the clamping groove of rectangular cross section is simple for structure, is easy to manufacture.

Another preferred embodiment of the present utility model, the cross section of the clamping groove are in isosceles trapezoid, the isosceles Trapezoidal longer base is on the top surface of refractory brick body.Using the embodiment, can better adapt to circular arc kiln body or The requirement on arch kiln top.

Another preferred embodiment of the present utility model, the two sides of the refractory brick body and the top of refractory brick body Face is vertical.Using the embodiment, the profile of refractory brick body is rectangular, is easy to manufacture.

The utility model further preferred embodiment, the two sides of the refractory brick body are same with clamping groove respectively The groove side of side is parallel.Using the embodiment, the requirement of circular arc kiln body can be equally well adapted for, and can be saved resistance to Material used in firebrick body.

Another further preferred embodiment of the utility model, the cross section semicircular in shape of the tongue-and-groove.Using the reality Mode is applied, the tongue-and-groove of cross section semicircular in shape is versatile, is suitable for the clamping requirement of different cross section tenon.

The another further preferred embodiment of the utility model, the cross section semicircular in shape of the tenon.Using the reality Mode is applied, the tenon of cross section semicircular in shape can be well matched with the tongue-and-groove of semi-circular cross-section, and clamping gap is small.

The further preferred embodiment of the utility model, the cross section of the tenon are trapezoidal.Using the embodiment party Formula, the trapezoidal tenon in cross section both can have certain clamping free degree again with semicircle tongue-and-groove clamping, especially suitable For circular arc kiln body or the requirement of arch kiln body.
