Specific embodiment

In order that the purpose of this utility model, technical scheme and beneficial effect are clearer, below in conjunction with accompanying drawing, to this The preferred embodiment of utility model is described in detail, to facilitate the technical staff to understand.

As shown in figs 1-9, described Isa furnace lead smelting high lead slag slag chute includes that slag chute A1, slag chute B2, slag are slipped Groove C3, slag chute A1, slag chute B2, slag chute C is inside is built-in type compulsory circulative cooling water copper pipe 4, and outside is cast copper The buried tube type forced circulation water cooling copper water nested structure of opening trench structure slag chute 5, slag chute A1 is provided with two in 90 ° of folders The slag notch I 6 at angle, slag notch II 7, slag notch I 6 are the urgent slagging passage of Isa furnace slag, and slag machine is cast in slagging to straight line；Slag notch II 7 is the normal slagging passage of Isa furnace slag, is the main part of this slag chute.Described slag chute C3 has four, slag chute It is sequentially connected using flange between A1 and slag chute B2, slag chute B2 and slag chute C3, slag chute C3 and slag chute C3.

Described Isa furnace lead smelting high lead slag slag chute is installed between Isa furnace slag tap and reduction furnace entrance, its peace Dress angle is 10 °, is easy to the flowing of Isa furnace high lead slag, Isa furnace high lead slag is successfully flowed into reduction furnace entrance.

The built-in type compulsory circulative cooling water copper pipe 4 buried in described slag chute A1, slag chute B2, slag chute C3 is melting The T2 copper pipes of non junction Φ 46 × 8 of copper water casting, the cooling water copper pipe structure exported using triple feed inlet three, it is ensured that slag chute A1, The cooling effect of high lead slag, meets technical cooling requirement in slag chute B2, slag chute C3, often saves slag chute design triple feed inlet three and goes out Mouth cooling water copper pipe, meets technical cooling requirement.

5mm thickness wear-resistant alloy layers are welded with the slag notch I 6 of described slag chute A1, slag notch II 7, due to slag chute The slag notch I 6 of A1, the exit of slag notch II 7 are that frequent section is washed away in slag flowing, so setting 5mm thickness wear-resistant alloy layers, can be prolonged The service life of long slag chute A1, it is ensured that production efficiency.

In the bottom interior wall of described slag chute A1 the fissure of displacement be inlaid with one layer of length × width × height for 240mm × 110mm × The refractory brick of 75mm, is inlaid with the fire resisting that one layer of length × width × height is 240mm × 110mm × 75mm on the side wall of slag chute A1 Brick, it is considered to during Isa furnace slagging, high temperature high lead slag（1100 DEG C of temperature, lead tolerance 56%）Slag chute A1 is flowed into, there is high temperature sludge liquid Slag chute A1 is washed away, makes its wear extent big, therefore the design inlays one layer of length × width × height for 240mm in the walls of slag chute A1 tetra- The refractory brick of × 110mm × 75mm, the bottom fissure of displacement inlays the refractory brick that one layer of length × width × height is 240mm × 110mm × 75mm, Reduce the abrasion of slag stream and wash away, more preferable covering slag chute A1.

Described slag chute B2, the trough rim of slag chute C3 are use length × width × height for 240mm × 110mm × 75mm resistance to The parallel protective layer built by laying bricks or stones of firebrick full sized brick, the groove arc of described slag chute B2 is one section of 800mm long and welding 5mm thickness is wear-resisting Alloy-layer arc ditch, is painted with plasticity material protective layer on the bottom land inwall of slag chute B2；The plasticity bed of material washes away mill during use After damage can conveniently, in time, quickly apply mend, reduce slag stream abrasion and wash away, more preferable covering slag chute B2, slag chute C3.Found through during use, the groove face erosive wear of slag chute B2 is the most serious, therefore slag chute B2 groove faces cambered design is one The welding 5mm thickness wear-resistant alloy layers of segment length 800mm, covering slag chute B2 extends its service life.Because of slag chute B2 and slag chute C3 is installed on 10 ° of technological datum face, is connected with the installation of slag chute A1 for ease of slag chute B2, therefore slag chute B2 is slipped with slag Groove A1 junctions are designed as -10 ° of flange connection surface.

The course of work of the present utility model：

The slag notch I 6 of Isa furnace lead smelting high lead slag slag chute is connected with Isa furnace slag tap, the outlet of slag chute C3 End be connected with reduction furnace entrance, and ensure Isa furnace lead smelting high lead slag slag chute setting angle be 10 °, Isa furnace high lead slag Slag chute A1 is entered by slag notch I 6 from Isa furnace slag tap, slag chute B2 is then passed to, then flow to slag chute C3, by slag chute C3 is flowed into reduction furnace.

Finally illustrate, preferred embodiment above is only used to illustrate the technical solution of the utility model and unrestricted, to the greatest extent Pipe is described in detail by above preferred embodiment to the utility model, but those skilled in the art should manage Solution, can make various changes, without departing from the utility model claims institute to it in the form and details The scope of restriction.
