Abstract
The utility model discloses a combination formula furnace wall of hot stove in long -life ore deposit, including steel deck, heat insulation layer, insulating layer, heat preservation and high temperature operational layer, the high temperature operational layer is by the last carbon brick layer of overlapping in proper order, well carbon brick layer and descend the carbon brick layer to constitute, and the contained angle is 60 degrees between the brickwork joint on last carbon brick layer and the brickwork joint on well carbon brick layer, and the contained angle is 60 degrees between the brickwork joint on well carbon brick layer and the brickwork joint on lower carbon brick layer. The utility model discloses a combination formula furnace wall makes furnace wall life reach more than 5 years, realizes the production of long continuous time as far as possible, improves the electric stove utilization ratio, also reduces because of the various consumption that the blowing out arouses, reduction in production cost by a wide margin simultaneously.
Description
Technical field:
This utility model belongs to field of metallurgy, relates to the combination type furnace lining of a kind of long-life mineral hot furnace, the combination type furnace lining of especially a kind of long-life mineral hot furnace producing calcium-silicon.
Background technology:
General mineral hot furnace furnace lining is made up of steel plate, heat insulation layer (asbestos board), thermal insulation layer (slag bulk cargo), heat-insulation layer (refractory brick) and hot operation layer (brick fuel or magnesia brick), and its major function is adiabatic and insulation. But because calcium-silicon product smelting temperature is high, and the corrosion function that furnace charge is to furnace lining, lining durability is very short, it is sometimes desirable within one month, changing a furnace lining, cause that production cost increases, economic benefit reduces. Meanwhile, existing furnace lining heat preservation and insulation is poor, and the heat loss of furnace lining surface radiating is up to 8.75%; Additionally, the compactness of furnace lining and globality are also poor, especially the cementitiousness between furnace bottom brickwork joint is low, causes that bottom working lining is destroyed by high-temp. furnace material serious; Reduce heat preservation and insulation and the service life of furnace bottom.
Therefore, extending furnace lining life so that it is the life-span reaches to maximize, is calcium-silicon industry problem urgently to be resolved hurrily.
Utility model content:
The purpose of this utility model is in that the shortcoming overcoming above-mentioned prior art, it is provided that the combination type furnace lining of long-life mineral hot furnace, and this combination type furnace lining heat preservation and insulation is good, and globality is also better, and lining durability is long.
The purpose of this utility model solves by the following technical programs:
A kind of combination type furnace lining of long-life mineral hot furnace, including steel plate, heat insulation layer, thermal insulation layer, heat-insulation layer and hot operation layer, described hot operation layer is made up of upper carbon brick layer overlapping successively, middle carbon brick layer and lower carbon brick layer, between brickwork joint and the brickwork joint of middle carbon brick layer of upper carbon brick layer, angle is 60 degree, and between brickwork joint and the brickwork joint of lower carbon brick layer of middle carbon brick layer, angle is 60 degree.
Described carbon brick is polish self-baked charcoal brick.
Described heat insulation layer is made up of asbestos board.
Described thermal insulation layer is made up of slag bulk cargo.
Described heat-insulation layer is made up of refractory brick.
The beneficial effects of the utility model are in that: combination type furnace lining of the present utility model makes furnace lining reach more than 5 years service life, realize long-time production continuously as far as possible, improve electric furnace utilization rate, also reduce the various consumption caused because of blowing out simultaneously, production cost is greatly reduced.
Accompanying drawing illustrates:
Fig. 1 is combination type furnace lining structure schematic diagram;
Wherein: 1 be upper carbon brick layer, 2 be middle carbon brick layer, 3 for lower carbon brick layer.
Detailed description of the invention:
Below in conjunction with embodiment, this utility model is described in further detail:
Referring to Fig. 1, a kind of combination type furnace lining of long-life mineral hot furnace, including steel plate, heat insulation layer, thermal insulation layer, heat-insulation layer and hot operation layer, described hot operation layer is made up of upper carbon brick layer overlapping successively, middle carbon brick layer and lower carbon brick layer, between brickwork joint and the brickwork joint of middle carbon brick layer of upper carbon brick layer, angle is 60 degree, and between brickwork joint and the brickwork joint of lower carbon brick layer of middle carbon brick layer, angle is 60 degree.
Described carbon brick is polish self-baked charcoal brick.
Described heat insulation layer is made up of asbestos board.
Described thermal insulation layer is made up of slag bulk cargo.
Described heat-insulation layer is made up of refractory brick.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model; it cannot be assumed that detailed description of the invention of the present utility model is only limitted to this; for this utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; some simple deduction or replace can also be made, all should be considered as belonging to this utility model and be determined scope of patent protection by submitted claims.
