Abstract

The utility model provides a slag runner spout device which can be replaced quickly for a blast furnace, comprising a slag runner main body, a slag runner steel groove, a supporting steel plate, a U-shaped spout, a baking-free refractory material and a hoisting hook; the support steel plate is welded with the slag runner steel groove; the prefabricated U-shaped spout with the boss at the bottom is bonded and connected with the boss on the slag runner main body through the baking-free refractory; the spout is connected with the supporting steel plate in a bonding way through a baking-free refractory material; the hoisting hook is connected with a hoisting ring on the spout; the slag runner main body is fixedly connected with the slag runner steel groove. The utility model has the advantages that: the U-shaped spout of the slag runner is made into a prefabricated part form, so that the links of crushing, pouring and baking a new spout of an old spout are saved, the old spout can be directly hung away after the original spout is damaged, the new spout is bonded on a supporting steel plate by baking-free refractory after a base surface is cleaned, and the technical problems of complexity, time consumption and labor consumption of crushing, pouring, baking and the like in the original process of repairing the spout of the slag runner are solved.

Description

Slag runner flow nozzle device capable of being replaced quickly for blast furnace

The technical field is as follows:

the utility model relates to a blast furnace ironmaking auxiliary assembly technical field especially relates to a blast furnace slag runner is with flowing nozzle device for blast furnace ironmaking maintenance system.

Background art:

high-temperature slag generated by blast furnace smelting flows into the INBA granulated slag punching device through a slag runner, the tail end of the slag runner is a slag runner flow nozzle, and the slag is downwards punched into the punching device to form solid slag particles under the punching of high-pressure water. The slag runner spout is easy to damage due to the scouring erosion and burning loss of high-temperature slag, the damaged liquid slag flows into the granulated slag flusher, the track is changed, the contact surface of the granulated slag flushing water and the slag flow of the slag deviates, the granulated slag flushing is incomplete, a part of slag is gathered in the flusher, the slag flushing effect is influenced, and the flusher is blocked or even burnt out due to the fact that a large amount of slag is gathered in serious cases, and the production safety of a blast furnace is seriously influenced. Therefore, the damaged slag runner nozzle needs to be replaced in time, the traditional replacement method is to break and knock the damaged slag runner nozzle by an air pick, erect a mould to pour refractory materials again, and bake the mould so as to prevent the repair failure caused by blasting due to the heating of the refractory materials when slag is discharged, the overhaul process is complex, tedious and time-consuming, the iron discharging sequence and slag discharging safety of a blast furnace are seriously affected, and the improvement is not favorably realized, so that the improvement is necessary.

The utility model has the following contents:

the utility model aims at overcoming the defects of the prior art, providing a slag runner spout device which has simple manufacture, convenient replacement and can effectively solve the problems of complex, time-consuming and labor-consuming repairing process of the traditional slag runner spout.

The utility model provides a technical scheme of above-mentioned technical problem is: the utility model provides a slag runner spout device which can be replaced quickly for a blast furnace, comprising a slag runner main body and a slag runner steel groove; the device is characterized by also comprising a supporting steel plate, a U-shaped flow nozzle, a baking-free refractory material and a hoisting hook; the support steel plate is welded with the slag runner steel groove; the prefabricated U-shaped spout with the boss at the bottom is bonded and connected with the boss on the slag runner main body through the baking-free refractory; the spout is connected with the supporting steel plate in a bonding way through a baking-free refractory material; the hoisting hook is pre-embedded in the side wall of the spout; the slag runner main body is fixedly connected with the slag runner steel groove.

The slag runner flow nozzle device capable of being replaced quickly for the blast furnace is characterized in that the flow nozzle is a U-shaped flow nozzle.

The utility model has the advantages that: the runner of the slag runner is made into a prefabricated part form, so that the links of crushing, pouring and baking a new runner of an old runner are saved, the runner can be directly hung away after the original runner is damaged, the new runner is bonded on a supporting steel plate by baking-free refractory after a base surface is cleaned, and the technical problems of complexity, time consumption and labor consumption in the process of crushing, pouring, baking and the like in the original repairing of the runner of the slag runner are solved.

Description of the drawings:

FIG. 1 is a front view of the embodiment of the present invention;

FIG. 2 is a side sectional view of a slag runner nozzle.

In the drawings: 1. a slag runner steel trough; 2. a support steel plate; 3. a spout; 4. a baking-free refractory material; 5. hoisting a hook; 6. a slag runner main body.

The specific implementation mode is as follows:

the embodiments of the present invention will be described in further detail with reference to the accompanying drawings: provided is a slag runner spout device for a blast furnace, which can be quickly replaced, as shown in figures 1 and 2: comprises a slag runner steel groove 1, a supporting steel plate 2, a spout 3, a baking-free refractory material 4, a hoisting hook 5 and a slag runner main body 6; the supporting steel plate 2 is welded with the slag runner steel groove 1; the prefabricated spout 3 with the boss at the bottom is connected with the boss on the slag runner main body 6 in a bonding way through the baking-free refractory material 4; the section of the spout 3 is U-shaped and is connected with the supporting steel plate 2 in a bonding way through a baking-free refractory material 4; the hoisting hook 5 is pre-embedded on the side inner wall of the spout 3; the slag runner main body 6 is fixedly connected with the slag runner steel groove 1.

The method of the utility model is that: after the slag runner spout is damaged, cleaning up the slag on the inner surface of the U-shaped spout 3 by using an air pick, and then hanging the spout hoisting hook 5 by using a special crane on a slag runner platform to hoist and transport the spout; then, cleaning the original refractory material by using a steel chisel, exposing the bottom supporting steel plate 2, and laying a new layer of baking-free refractory material 4 after purging; placing the pre-renewed U-shaped spout 3 on the refractory material, and adjusting the position to align the boss of the U-shaped spout 3 with the boss of the slag runner main body 6; and finally, paving a layer of baking-free refractory material 4 at the joint of the U-shaped spout 3 and the slag runner main body 6, and leveling to put into use. The utility model discloses reform transform traditional slag runner stem bar into prefabricated form, pour in advance and dry by baking, hang away damaged stem bar during the change and change new stem bar can, because the lower part has the steel sheet to support and adopt the boss to connect, can not drop, be difficult for leaking the sediment, and the refractory material of bonding usefulness is in the stem bar prefab below, the quantity is few, need not toast, press promptly and use, need not be broken, need not toast, make things convenient for the dismouting, the change time has been saved greatly, it is time-consuming to have solved traditional method and changed slag runner stem bar, hard, the problem of process complicacy.
