Structure includes body of heater and electrode, by electric arc is produced after being powered when furnace of calcium carbide works, the high-temperature heating furnace charge formed by electric arc, makes
Furnace charge reaches chemical reaction institute calorific requirement.Wherein, electric arc send region that high temperature can be applied directly to electric arc operation area or
Molten bath, the region is in the lower section of electrode tip until furnace bottom.
The inwall of furnace of calcium carbide is typically built using high-alumina brick, and it is uniform that existing high-alumina brick is typically difficult to in-furnace temperature,
And when building, gap is there may be between high-alumina brick, easily occurs the fiery phenomenon that leaps up in use, not only causes fuel unrestrained
Take, and very big potential safety hazard be present, do not meet modern production demand.
Utility model content
The technical problems to be solved in the utility model is, in view of the shortcomings of the prior art, proposing that one kind can make in furnace of calcium carbide
Temperature is uniform and reduces the furnace of calcium carbide high-alumina brick in gap.
The utility model is to solve the technical scheme that above-mentioned technical problem proposes to be：A kind of furnace of calcium carbide high-alumina brick, including
The brick body of rectangular-shape, the length direction of the upper surface of brick body along brick body offer at least one dovetail groove, the lower surface of brick body
Be connected with it is at least one match with dovetail groove convex stupefied, convex stupefied position is corresponding with the position of dovetail groove, the side of brick body
Covered with metal tungsten coating；One side surface of brick body is connected with least one locating piece, relative another in surface where locating piece
Side surface offers the locating slot to match with locating piece, and the position of locating piece is corresponding with the position of locating slot.
The improvement of above-mentioned technical proposal is：In brick body at least one lightening recesses are offered along the length direction of brick body.
The improvement of above-mentioned technical proposal is：Dovetail groove and it is convex it is stupefied be respectively two.
The improvement of above-mentioned technical proposal is：Lightening recesses are three.
The improvement of above-mentioned technical proposal is：Locating piece and locating slot are respectively one.
The utility model is using the beneficial effect of above-mentioned technical proposal：
（1）With high-alumina brick because brick body upper surface offers dovetail groove, lower surface is connected with furnace of calcium carbide of the present utility model
Match with dovetail groove convex stupefied,, can be close by upper and lower two blocks of high-alumina bricks by the convex stupefied and cooperation of dovetail groove when building by laying bricks or stones
It is fixed together, prevents high-alumina brick from offseting, gap is there may be between reduction high-alumina brick, so as to prevent being leapt up during use
Fiery phenomenon；
（2）Furnace of calcium carbide high-alumina brick of the present utility model utilizes metal because the side of brick body is covered with metal tungsten coating
The high thermal conductivity of tungsten electrode, heat can carry out face transmission along metal tungsten coating rapidly, can be fast by heat in calcium carbide stove heat
Speed is scattered, and be ensure that in-furnace temperature is uniform, is improved production efficiency and quality；
（3）Furnace of calcium carbide of the present utility model with high-alumina brick because a side surface of brick body is connected with locating piece, brick body with
The relative another side surface in surface where locating piece offers the locating slot to match with locating piece, the position of locating piece and positioning
The position of groove is corresponding, when piling up, passes through the cooperation of locating piece and locating slot so that and two blocks of left and right high-alumina brick is brought into close contact,
Gap is there may be between reduction high-alumina brick, so as to prevent occurring the fiery phenomenon that leaps up in sintering procedure；
（4）Furnace of calcium carbide of the present utility model is recessed because the length direction of brick body interior edge brick body offers loss of weight with high-alumina brick
Groove, had both reduced the cost of high-alumina brick production, and can reduce kiln after piling up integrally conducts oneself with dignity, and reduced energy consumption.
