For anode scrap after electrolysis after shaft furnace melts, the liquid copper of melting flows into holding furnace, fixed chute by fixed chute
Operating temperature typically at 1120~1150 DEG C or so.Holding furnace uses central feeding mode, and the front end of chute need to stretch into insulation
About 20cm in stove.In order to maintain the temperature of liquid copper in holding furnace, dilute oxygen burning burner of holding furnace is being located at this section of chute just
Top, the part chute is all the time in high temperature, oxygen-enriched environment, and holding furnace fume recovery system is formed to closed chute
Negative pressure, causes chute burner flame persistently to burn the part chute, and the normal operation circumstances of this section of chute are more severe.Row at present
The chute majority of the region design and installation is cast iron HT220 materials in the industry, and oxidation rate is fast under high temperature, excess oxygen, easily
Scaling loss, and solderability is poor, it is big that chute repairs difficulty, and changing chute need to frequently stop production parking, seriously constrain normal production.
It thus provides a kind of novel oxidation-resistant, chute can be repaired, solve the problems, such as the part chute, be one
Good problem to study.
The content of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provide it is a kind of simple in construction, and can be to chute
Oxidized portion repaired, and rehabilitation cost is relatively low, and chute can be recycled for multiple times, and greatlys save the anti-of production cost
Oxidation, chute can be repaired.
What the purpose of this utility model was realized in：
Novel oxidation-resistant, chute, including chute main body can be repaired, and set chute body ends be fixedly connected with panel
1 and the cooling system 4 that is arranged in chute main body；It is characterized in that：Described chute main body includes 316L stainless steels
Chute body front end 3, the chute master for 304 stainless steels being connected with the chute body front end 3 of 316L stainless steels
Body rear end 2；
The described chute body rear 2 for being fixedly connected with panel 1 and 304 stainless steels is fixed, and on panel plate body
It is provided for the bolt hole fixed with chute steel sheel；
Described cooling system 4 includes 304 Stainless Steel Coils of 1 20 being arranged in chute main body and 6 12
304 stainless steel tubes, 20 304 Stainless Steel Coils are be distributed along chute direction in chute bottom and chute both sides 6 12
304 stainless steel tubes connect, and 12 6 304 stainless steel tubes are evenly equipped with perforate, under chute normal operating conditions to 20 it is stainless
In steel disk pipe protectiveness nitrogen is blasted through nitrogen inlet 5.
Positive beneficial effect：Novel chute described in the utility model, can effectively solve common chute in long-time high temperature
In oxygen-enriched environment, the oxidation of appearance and problem on deformation.Chute described in the utility model, has been passed through nitrogen, the shape near chute
Into anaerobic environment, under the high temperature conditions, oxygen-enriched environment is alleviated significantly and is aoxidized to caused by chute, extends the use of chute
Life-span, production practices show, extend 3 times than original chute service life, reduce the frequency for more renewing chute, for a long time
After use, the oxidized portion of chute can be repaired, and rehabilitation cost is relatively low, and chute can be recycled for multiple times, and save significantly
About production cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
It is in figure：It is fixedly connected with panel 1, chute body rear 2, chute body front end 3, cooling system 4, nitrogen inlet 5.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is described further：
As shown in figure 1, novel oxidation-resistant, can repair chute, including chute main body, and consolidating for chute body ends is set
Surely connect panel 1 and the cooling system 4 that is arranged in chute main body, blast nitrogen through nitrogen inlet 5 under operating mode, slow down Strong oxdiative
Atmosphere, chute cooling is carried out, is increased the service life.
；Described chute main body includes the chute body front end 3 of 316L stainless steels, with slipping for 316L stainless steels
The chute body rear 2 for 304 stainless steels that groove body front end 3 is connected；
The described chute body rear 2 for being fixedly connected with panel 1 and 304 stainless steels is fixed, and on panel plate body
