Abstract
The invention relates to a protective device for a heating burner nozzle of a high-temperature copper solution tundish sprue. One end of a semicircular-ring outer cover is provided with a casing pipe; the semicircular-ring outer cover and the casing pipe have the same center line; the casing pipe is movably cooperated to be sheathed into a gas steel pipe and is tightly leaned against an inner thread pipe joint; the semicircular-ring outer cover covers the inner thread pipe joint and the heating burner nozzle; one side surface of the casing pipe is welded with a nut matched with a screw; the inner hole of the screw and the pipe wall of the casing pipe are through; and a gap of 15-25mm is remained among the inner wall of the semicircular-ring outer cover, the inner thread pipe joint and the heating burner nozzle. According to the protective device, water and wind can be blocked for the heating burner nozzle so as to prevent water or wind from extinguishing the heating burner nozzle, guarantee the continuity of the casting technology and improve production work efficiency.
Description
Technical field
The present invention relates to the device of continuous casting and rolling in the non-ferrous metal metallurgy, particularly a kind of protector of high-temperature copper liquid tundish cast gate heating burner.
Background technology
In the copper bar continuous casting and tandem rolling system, the copper liquid that the cast gate of the tundish of high-temperature copper liquid is solidified easily stops up, and the effect of heating burner is before the casting cast gate to be heated to about 1000 ℃, and the high-temperature copper liquid of tundish can be flowed out from cast gate smoothly.But the heating burner receives the influence of surrounding environment easily in heating process; Because the heating burner is near the cast wheel of copper liquid crystallization and freezing in the copper bar continuous casting and tandem rolling system; And cast wheel must be sprayed water and cooled off; The cooling water that is used for cast wheel is splashed on the heating burner sometimes and wind is arranged on every side, and the heating burner is extinguished.
Summary of the invention
The technical problem that the present invention will solve provides a kind of protector of high-temperature copper liquid tundish cast gate heating burner.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of high-temperature copper liquid tundish cast gate heating burner protector comprises the heating burner that is connected with gas steel pipeline through female union; The end that the semicircular ring outer cover is closed is provided with sleeve pipe, and semicircular ring outer cover and sleeve pipe have same center line, and sleeve pipe is inserted in said gas steel pipeline movingly and near female union, the semicircular ring outer cover covers female union and heating burner; One side of sleeve pipe is welded with and the screw rod nut engaged, and the endoporus of nut and the tube wall of sleeve pipe are penetrating, leaves 15-25 mm gap between semicircular ring outer cover inwall and female union and the heating burner.
The invention has the beneficial effects as follows: can and keep out the wind for heating burner dash, thereby anti-sealing or wind extinguish the heating burner, guarantee the continuity of casting process, improve the production work efficiency.

The specific embodiment
Embodiment 1Shown in Fig. 1-6: a kind of protector of high-temperature copper liquid tundish cast gate heating burner comprises the heating burner 1 that is connected with gas steel pipeline 3 through female union 2; Semicircular ring outer cover 5 closed ends are welded with sleeve pipe 4, and semicircular ring outer cover 5 has same center line with sleeve pipe 4; Sleeve pipe 4 is inserted in gas steel pipeline 3 movingly and near female union 2, semicircular ring outer cover 5 covers female union 2 and heating burner 1.One side of sleeve pipe 4 is welded with and screw rod 7 nut engaged 6, and the tube wall of the endoporus of nut 6 and sleeve pipe 4 is penetrating.Leave 20 mm gaps between semicircular ring outer cover 5 inwalls and female union 2 and the heating burner 1.
The sleeve pipe 4 that cast gate is heated the burner protector is inserted in gas steel pipeline 3 near female union 2, and sleeve 4 sides, the screw rod 7 that cooperates with nut 6 screw in the endoporus of sleeve pipe 4 tube walls, cast gate is heated the burner protector be fastened on the gas steel pipeline 3.
