Abstract
The utility model discloses a water-cooled furnace cover structure which comprises an upper frame and a lower frame, wherein the upper frame and the lower frame form a funnel-shaped cover body, three water-cooling blocks are arranged between the upper frame and the lower frame, each water-cooling block comprises four water paths, each water path consists of an inclined supporting pipe, an inlet of each water path is connected with a water inlet distributor, and an outlet of each water path is connected with a water return distributor. The utility model has reasonable and ingenious structural design, increases the water passing diameter areas of the water paths and the near and meeting water paths on the premise of unchanging the size of the water-cooled furnace cover, reduces the resistance pressure drop of the water paths, reduces the pulling crack phenomenon caused by large temperature gradient in the thickness direction due to over thick pipe wall, and each water path on the furnace cover is uniformly distributed, thereby avoiding the pulling crack of the steel pipe caused by nonuniform heating of the furnace cover, reducing the diameter of the water passing pipe due to rapid water cooling, improving the water cooling speed, and avoiding the burning of the water-cooled wall caused by the thermal resistance deterioration heat transfer condition generated by local film boiling in the pipe.
Description
Technical Field
The utility model relates to a water-cooled furnace cover structure.
Background
The water-cooled furnace cover has a particularly severe working environment, is in a high-temperature state for a long time in the smelting process, the temperature in the furnace can reach about 1700 ℃ at most due to the reflection of slag, the furnace cover is also frequently subjected to the temperature impact effect of rapid cooling and rapid heating, the temperature of the furnace cover is rapidly reduced to below 1000 ℃ after tapping, sometimes the time for waiting and charging is longer, the temperature is reduced more, and the local temperature difference on the furnace cover is increased. In addition, the furnace cover is also eroded and washed by high-temperature furnace gas, furnace slag, smoke dust and the like in the smelting process, so that a pipeline of the furnace cover is easy to crack and peel, and water leakage accidents are caused.
SUMMERY OF THE UTILITY MODEL
The utility model relates to a water-cooled furnace cover structure, which has uniform heat distribution, avoids the pulling crack of a steel pipe and prolongs the service life of the furnace cover.
In order to realize the purpose, the structure adopted by the utility model is as follows: water-cooling bell lid structure, including last frame and underframe, go up frame and underframe and constitute and leak hopper-shaped lid, go up three water-cooling pieces of arranging between frame and the underframe, every water-cooling piece includes four water routes, and every water route comprises the bracing pipe, and four water routes evenly cover on every water-cooling piece, and the access connection water inlet distributor in every water route, water route exit linkage return water distributor.
The lowest end of the water cooling block is 20-40 mm higher than the lowest end of the lower frame.
And a plurality of water-stop plates are arranged between the upper frame and the lower frame.
The upper frame and the lower frame are provided with damping holes.
The beneficial effects are as follows: the utility model has reasonable and ingenious structural design, increases the water passing diameter areas of the water paths and the near and meeting water paths on the premise of unchanging the size of the water-cooled furnace cover, reduces the resistance pressure drop of the water paths, reduces the pulling crack phenomenon caused by large temperature gradient in the thickness direction due to over thick pipe wall, and each water path on the furnace cover is uniformly distributed, thereby avoiding the pulling crack of the steel pipe caused by nonuniform heating of the furnace cover, reducing the diameter of the water passing pipe due to rapid water cooling, improving the water cooling speed, and avoiding the burning of the water-cooled wall caused by the thermal resistance deterioration heat transfer condition generated by local film boiling in the pipe.
