Abstract
The utility model provides a blast-furnace tuyere structure, comprising a shell and a runner arranged in the shell. The blast-furnace tuyere structure is characterized in that the runner is a double runner with independent flowing channels. According to the blast-furnace tuyere structure provided by the utility model, the double runner with independent flowing channels is arranged. If a runner at the end is burnt, water is stopped by turning off the runner and a second runner in back can continuously work, so that the problem of emergency damping down caused by that a tuyere small sleeve is burnt for a large area due to an unsmooth furnace state can be avoided. Not only can a blast furnace be ensured to normally work, and the production efficiency be improved, but also the service life of the equipment is prolonged and the equipment replacement cost is saved.
Description
Technical field
The utility model relates to a kind of blast-furnace tuyere structure.
Background technology
The blast furnace technology development so far, and is very ripe, but ironmaking bound pair blast furnace long-lived is pursued and studied endless.Along with technical progresses such as technology, anti-material and equipment, blast furnace generation furnace life from before developed into the present more than ten years in several years.At present, the most of single channel that adopts of blast-furnace tuyere is tubular or collapsible, has eliminated cavity type basically.The work-ing life in the tubular or collapsible air port of single channel is according to blast furnace size and operant level; Although with respect to traditional cavity type large increase has been arranged, appoint the air port that so can't avoid blast wandering to cause to burn the leakage problem normally in 1～3 year its work-ing life; And the air port one side of leaking needs urgent or interim damping down; Can cause that on the other hand the working of a furnace fluctuates and leaks, what not only influence was produced normally carries out, and can shorten the work-ing life of anti-material.
The utility model content
The purpose of the utility model is to provide a kind of blast-furnace tuyere structure that can guarantee the blast furnace ordinary production.
The purpose of the utility model is achieved in that a kind of blast-furnace tuyere structure, comprises housing and is arranged on the intravital runner of said shell, it is characterized in that: said runner is double flow duct and independent circulation.
First flow in the above-mentioned double flow duct is arranged on the housing termination and is communicated with the tubular channel that is provided with water-in and water outlet.
The termination cooling room of above-mentioned first flow is annular single passage.
Second runner in the above-mentioned double flow duct is arranged on the housing rear portion and is spiral through-flow structure or folding through-flow structure, on back cover, is provided with water-in and water outlet.
The utlity model has following beneficial effect, the utility model is provided with the double flow duct of independent circulation, if termination runner scaling loss; Can close its Inlet and outlet water, rear portion second runner still can work on, and has avoided because blast wandering causes that the tuyere small sleeve big area burns out and causes urgent damping down problem; Not only guaranteed the blast furnace ordinary production; Improve production efficiency, and helped prolonging equipment life, practiced thrift the equipment replacement cost.

Embodiment
Embodiment 1, and a kind of blast-furnace tuyere structure comprises housing and is arranged on the intravital runner of shell, and runner is double flow duct and independent circulation.First flow is arranged on housing termination 1, the second runner and is arranged on housing rear portion 2, and the first flow and second runner separate through dividing plate 3b; First flow is communicated with the tubular channel 4 that is provided with water-in I 5 and water outlet I 6, and the termination cooling room of first flow is annular single passage; Second runner is a spiral through-flow structure, is divided into chamber I, chamber II, chamber III and chamber IV through dividing plate 3d, is provided with water-in II 7 and water outlet II 8 at back cover 2.
Tubular channel 4 comprises water inlet pipe 4a and rising pipe 4b, and the water inlet of first flow is passed dividing plate from water-in I 5 through the independent direct through-flow of water inlet pipe 4a that is provided with and got into housing termination 1, flows out from water outlet I 6 through rising pipe 4b after 1 one weeks around the termination; The water of second runner gets into big cavity in the housing from water-in II 7, gets into the chamber I from dividing plate 3b pocket through-flow, flows out through water outlet II 8 through chamber II, chamber III and chamber IV spiral after one week around the chamber I.
Embodiment 2, and a kind of blast-furnace tuyere structure comprises housing and is arranged on the intravital runner of shell, and runner is double flow duct and independent circulation.First flow is arranged on housing termination 1, the second runner and is arranged on housing rear portion 2, and the first flow and second runner separate through dividing plate 3b; First flow is communicated with the tubular channel 4 that is provided with water-in I 5 and water outlet I 6, and the termination cooling room of first flow is annular single passage; Second runner is folding through-flow structure, is divided into the folding tuyere body one all water flow passage that detour through dividing plate 3d, is provided with water-in II 7 and water outlet II 8 at back cover 2.
Tubular channel 4 comprises water inlet pipe 4a and rising pipe 4b, and the water inlet of first flow gets into housing termination 1 from water-in I 5 through the direct through-flow of the independent water inlet pipe 4a that is provided with, and spiral flows out from water outlet I 6 through rising pipe 4b 1 one all backs around the termination; The water of second runner gets into big cavity in the housing from water-in II 7; Get into the chamber I from dividing plate 3b pocket I k1 through-flow; Spiral gets into the folded water circulation road that by dividing plate 3d be divided into through dividing plate 3b pocket II k2 around the chamber I after one week, and the week of detouring is after 8 outflows of water outlet II.
