Abstract
The utility model relates to a novel blast furnace wind opening small sleeve capable of prolonging service life, which comprises a wind opening small sleeve body. A wind supply channel is arranged inside the wind opening small sleeve body, and an inlaying layer is respectively arranged on the outer wall of the wind opening small sleeve body, the inner wall of the wind supply channel and the front end face of the wind opening small sleeve. The inlaying layers arranged on the outer wall of the wind opening small sleeve body and the inner wall of the wind supply channel are adamantine spar-chronium composite materials. The inlaying layer arranged on the front end face of the wind opening small sleeve is ceramic materials. The inlaying layers can effectively resist iron slag corrosion, high-speed coal powder injection and abrasion of hot wind and effectively prolong service life of the blast furnace wind opening small sleeve, thereby reducing blast furnace production accidents.
Description
Technical field
The utility model relates to the little cover of a kind of new type BF tuyere, the little cover of especially a kind of new type BF tuyere that increases the service life.
Background technology
The blast furnace tuyere small sleeve that uses at present; It all is the little cover that is made by metallic copper; Blast furnace tuyere small sleeve is in tuyere position, and slag iron corrosion easily, high speed coal powder injection and hot blast must wear and tear, and cause work-ing life very short; Like untimely processing and initiation safety or industrial accident easily, cause great inconvenience for the production of blast furnace.
Summary of the invention
The purpose of the utility model provides a kind of new type BF tuyere that can effectively increase the service life little cover with regard to being according to the defective of above-mentioned prior art.
The technical scheme of the utility model is: the little cover of a kind of new type BF tuyere; Comprise the tuyere small sleeve body; Tuyere small sleeve body inside is provided with air-supply passage, it is characterized in that: tuyere small sleeve body outer wall, air-supply passage inwall and tuyere small sleeve front end face are respectively equipped with mosaic coating.
The mosaic coating that said tuyere small sleeve body outer wall and air-supply passage inwall are provided with is corundum-chromium composite material.
The mosaic coating that said tuyere small sleeve front end face is provided with is a stupalith.
The beneficial effect of the utility model is: on blast furnace tuyere small sleeve body outer wall and air-supply passage inwall and tuyere small sleeve front end face, stud with mosaic coating; Can effectively resist the wearing and tearing of the corrosion of slag iron, high speed coal powder injection and hot blast; Effectively prolong the work-ing life of blast furnace tuyere small sleeve, thereby reduce the generation of blast furnace industrial accident.
Description of drawings
Fig. 1 is the sectional view of the utility model
1 tuyere small sleeve body, 2 air-supply passages, 3 mosaic coatings, 4 tuyere small sleeve front end faces among the figure
Embodiment
Further specify the little cover of a kind of new type BF tuyere according to accompanying drawing, comprise tuyere small sleeve body 1, tuyere small sleeve body 1 inside is provided with air-supply passage 2, and tuyere small sleeve body 1 outer wall, air-supply passage 2 inwalls and tuyere small sleeve front end face 4 are respectively equipped with mosaic coating 3.
