Abstract
The invention relates to a small inclined tuyere sleeve, relates to an ironmaking blast-furnace tuyere sleeve and solves the problem that front ends of traditional small inclined tuyere sleeves are easy to abrade. The small inclined tuyere sleeve comprises a small tuyere sleeve body, a front end surface and a rear end surface are fixed at two ends of the small tuyere sleeve body respectively and are parallel to each other, a hot air channel is arranged in the small tuyere sleeve body, and a centre line of the hot air channel and a centre line of the rear end surface form an angle. According to the small inclined tuyere sleeve, the front end surface and the rear end surface of a tuyere are parallel to each other, so that the upper portion of the front end surface isn't protruded towards the inside of the tuyere, the abrasion of the upper portion of the front end surface can be reduced or even avoided, the quantity of damaged small tuyere sleeves can be reduced, the reduction of the damping down ratio of a blast furnace is facilitated, and energy conservation and emission reduction of the blast furnace are facilitated.
Description
Technical field
the present invention relates to a kind of ironmaking tuyere of blast furnace cover, the young cover of specifically a kind of skew wind.
Background technology
The blast furnace that
are used to smelt iron; Need to pass through particularly tuyere small sleeve heat air delivery in stove of air port; Because special requirement; Tuyere small sleeve is divided into straight air port and skew wind mouth again, and conventional its front end face of skew wind mouth is general vertical with the hot-air channel medullary ray, so just makes the front/rear end of tuyere small sleeve not parallel.Because the front/rear end of this tuyere small sleeve is not parallel, causes tuyere small sleeve front end face top to seem and in stove " protrusion " causes tuyere small sleeve front end face top easy abrasion.
Summary of the invention
the object of the present invention is to provide the young cover of a kind of skew wind, solve the problem of the young cover front end of traditional skew wind easy abrasion.
the technical solution adopted for the present invention to solve the technical problems is: the young cover of a kind of skew wind; Comprise the tuyere small sleeve body; Tuyere small sleeve body two ends are fixed with front end face and aft end face respectively, it is characterized in that, described front end face is parallel with aft end face; Be provided with hot-air channel in the tuyere small sleeve body, the medullary ray shape of the medullary ray of hot-air channel and aft end face in an angle.
the invention has the beneficial effects as follows: because the aft end face and the front end face in this air port are to be parallel to each other; Its front end face top does not just seem projecting inward to stove; Can reduce even avoid the wearing and tearing of front end face top; Can reduce tuyere small sleeve and damage quantity, help reducing the blast furnace staying rate, help energy Conservation of Blast Furnace and reduce discharging.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among
figure: 1 tuyere small sleeve body, 2 front end faces, 3 aft end faces, 4 hot-air channels.
Embodiment
are as shown in Figure 1; The young cover of a kind of skew wind; Comprise tuyere small sleeve body 1, tuyere small sleeve body 1 two ends are fixed with front end face 2 and aft end face 3 respectively, and described front end face 2 is parallel with aft end face 3; Be provided with hot-air channel 4 in the tuyere small sleeve body 1, the medullary ray shape of the medullary ray of hot-air channel 4 and aft end face 3 in an angle.
hot-air channel 4 is downward-sloping; Thereafter end face 3 is parallel to each other with front end face 2, and therefore, front end face 2 tops just do not seem projecting inward to stove; Can reduce even avoid the wearing and tearing of front end face 2 tops; Can reduce the young cover of skew wind and damage quantity, help reducing the blast furnace staying rate, help energy Conservation of Blast Furnace and reduce discharging.
