Abstract
The utility model relates to a long service life energy saving type copper cooling wall for a blast furnace, comprising a copper cooling wall basal body, a flush bonding connecting piece, and an amorphous refractory masonry. The flush bonding connecting piece is cast steel with good high temperature resistance, wear-corrosion resistance, and heat shock resistance, or other materials with similar performances; the shape of the flush bonding connecting piece can be changed according to different utilization positions and requirements. The flush bonding connecting piece is tightly connected with a hot face basal body of a copper cooling wall, and the amorphous refractory material is tamped in the flush bonding connecting piece and at the outer part of the flush bonding connecting piece. Original high heat transfer rate of the copper cooling wall is reserved, advantages of greater slag resistance, greater iron flow corrosion resistance, and greater thermal resistance of a brick-clad cooling wall of similar traditional cast iron or cast steel are added. The utility model is convenient for blast furnace operation and inner profile design, obvious energy saving effects can be obtained, the service life of the utility model can be prolonged, and copper resource can be also saved. The utility model is particularly suitable for the use on the abdominal region of a furnace, and better effects can be obtained.
Description
The utility model belongs to technical field of metallurgical equipment, relates to bosh, the furnace bosh of blast furnace, the energy-conservation and long-livedization structure of restoration of lower stack copper cooling wall particularly.
In the prior art, be used for the copper cooling wall at each position, heating surface all adopts simple oat tail groove structure, in dovetail-indent the tamping unshape refractory, solve the wall dross, increase the needs of thermal resistance, by this kind structure to reach long-lived and energy-conservation purpose.Because soon, body of heater middle and lower part, furnace bosh, the especially interior bricking of the stove of bosh position protection copper cooling wall just damaged substantially, protect body of heater and keep blast furnace operating by copper cooling wall fully after blast furnace came into operation.There are the following problems for this technology:
1. heating surface adopts tamping unshape refractory in simple oat tail groove structure, the dovetail-indent; wall is smooth; be difficult for dross to form protection lining body; the furnace charge that the slag crust that leans on strong cooling to form more easily is lowered by impacts, collides and comes off; wall body copper metal is often exposed; bosh position copper metal directly contacts with the high temperature sludge flowing molten iron because of there is certain elevation angle its use location, easily by melting loss.Other position then thermal resistance diminishes, and heat waste strengthens.
2. utilize the high heat transfer rate of copper, strengthen cooling intensity, after bricking damages in stove, constantly form the slag crust of protection wall body, avoid wall body often directly to contact with high temperature gas flow with the high temperature sludge flowing molten iron, reaching long-lived purpose, but energy consumption is higher.Bosh position cooling stave matrix easily can not be solved fully by the problem of melting loss.
The purpose of this utility model is exactly at the problems referred to above, propose the thermal resistance of a kind of wall body own big, help dross, slag crust is difficult for the copper cooling wall structural shape that integral body comes off, thereby reach long-lived and energy-conservation effect than the structural shape of prior art.
The purpose of this utility model realizes that in the following manner the long-life energy-saving copper cooling wall comprises copper cooling wall matrix (containing and outside water pipe, the web member etc. of being connected), embedded web member, unshape refractory masonry.It is characterized in that: embedded web member is that high temperature resistant, erosion resistant, resistance to heat shocks can be made by good cast steel or other performance analog materials, and closely is connected with copper cooling wall hot side matrix, and web member is subjected to the good cooling protection of copper cooling wall, its long service life; The tamping unshape refractory forms masonry between the web member and in the dovetail-indent on the copper cooling wall matrix; be equivalent on existing copper cooling wall structural shape, increase bigger traditional cast iron or the cast steel edge brick cooling stave of one deck thermal resistance; initial stage direct thermal insulation protection copper cooling wall matrix; cut down the consumption of energy, the later stage relies on its structural advantage to be detained slag, forms slag crust protective layer preferably; and difficult drop-off; thereby protection copper cooling wall matrix prolongs the cooling stave life-span, reduces the blast furnace energy consumption.
The utility model is described in further detail below in conjunction with Figure of description:
The blast furnace of the utility model is made up of copper cooling wall matrix 3 (containing and outside water pipe, the web member etc. of being connected), embedded web member 2, unshape refractory masonry 1 with the long-life energy-saving copper cooling wall, is with dried dovetail-indent 4 on the copper cooling wall matrix 3.
At the hot side of traditional copper cooling wall matrix 3, increase embedded web member 2 connection grooves, outside wall thickness need slightly change according to design, its basic structure was with the copper cooling wall of prior art.
Embedded web member 2 for high temperature resistant, erosion resistant, resistance to heat shocks can be good cast steel or the cast of other performance analog materials or machining form, it can be the solid memder that covers monoblock copper cooling wall matrix 3 hot sides, also can be a plurality of members that can be combined into the regulation shape, the one end closely is connected with the hot side of copper cooling wall matrix 3 by casting or machining, and the other end is used for connecting and supporting unshape refractory masonry 1.
Unshape refractory masonry 1 is the material of selecting for use of prior art, and tamping forms masonry in the dovetail-indent 4 of copper cooling wall matrix and between the embedded web member 2 in also embedded web member 2 can being wrapped in.
The copper cooling wall of the utility model and prior art relatively, owing to increased embedded web member 2, the high heat transfer rate that had both kept the copper cooling wall of prior art, increased the flowing molten iron of anti-slag corrode and the bigger advantage of thermal resistance of similar traditional cast iron or cast steel edge brick cooling stave again, itself is prolonged in the life-span, energy-saving effect improves.Especially bosh position; because the singularity of its use location; after bricking damaged in the stove of protection cooling apparatus, under the effect of embedded web member 2, slag stream was easy to be detained the formation slag crust; and slag crust is difficult for integral body and comes off; even local shedding has also avoided lower the direct of copper cooling wall matrix 3 of high temperature sludge flowing molten iron and fusing point to contact, in use substantially; rely on preferably the slag crust protection, its life-span prolonged, energy-saving effect also is improved.Other position, more energy-conservation than the copper cooling wall of prior art before chemistry, the embedded web member of thermal stresses erosion damage, prolongs life is that chemistry, the embedded web member of thermal stresses erosion damage were former during this period of time.
The utility model because the shape of embedded web member can change with the design needs according to the use position is different, help the planner when utilizing all kinds of cooling apparatus, can select easily, and guarantee to have the interior type of blast furnace operating preferably.
The copper cooling wall of the utility model and prior art relatively has longer service life, energy-conservation, saving copper The remarkable advantage of resource, and help to keep the preferably interior type of blast furnace operating, reduce the blast furnace production cost.
