AI Technical Summary
The existing water seal structure consumes high energy, and heat transfer in the furnace causes the water temperature to rise in the water seal, and the evaporated water vapor enters the furnace, affecting the heating quality of stainless steel workpieces.
The water sealing tank is divided into an inner room and an outer room. The inner room is filled with water, and the outer room is not filled with water. The wet water sealing knife is located in the inner room, and the dry water sealing knife is located in the outer room, forming a maze sealing structure, which prevents the furnace gas from directly eroding the water in the inner room and reduces the generation of water vapor, and the slag falls into the outer room to remove.

Abstract
Description
Technical Field
[0001] The utility model belongs to the field of water seal structures, and particularly relates to a walking beam furnace water seal structure for stainless steel heating. Background Art
[0002] In a walking beam furnace, the billets in the furnace are alternately transported forward by a movable bottom and a fixed bottom. The function of the fixed bottom is to support the workpieces, that is, during the movement of the movable bottom, when the workpiece descends in place, it lands on the fixed bottom to play a role in supporting the workpiece. The movable bottom realizes the functions of rising, advancing, descending, and retreating of the movable bottom through a walking mechanism, and the path it takes is approximately a rectangle, thereby realizing the movement of the workpiece in the furnace.
[0003] The furnace bottom of a walking beam heating furnace is generally composed of a walking beam bottom and two fixed bottoms or two walking beam bottoms and three fixed bottoms. The water seal is installed below the combined position of the movable bottom and the fixed bottom, and is a structure that prevents furnace gas from escaping through the gap between the walking beam bottom and the fixed bottom when the movable bottom rises, descends, or moves horizontally.
[0004] The existing water seal structure has high energy consumption, and the water temperature in the water seal increases due to heat transfer in the furnace. The evaporated water vapor enters the furnace, affecting the heating atmosphere in the furnace. The evaporated water vapor will cause local low temperature at the gap position between the fixed bottom and the movable bottom, and there are obvious "black marks" on the workpiece at this position, which has a great impact on the processing quality of stainless steel materials. Summary of the Utility Model
[0005] The utility model provides a walking beam furnace water seal structure for stainless steel heating, aiming to solve the problems of high energy consumption of the existing water seal structure, the increase of water temperature in the water seal due to heat transfer in the furnace, the entry of evaporated water vapor into the furnace, affecting the heating atmosphere in the furnace and the quality of the stainless steel workpiece heating furnace.
[0006] The utility model is realized as follows: A walking beam furnace water seal structure for stainless steel heating includes a walking beam bottom and a fixed bottom. A water seal tank inner chamber is arranged below the fixed bottom, and a water body is arranged inside the water seal tank inner chamber. A water seal tank outer chamber is arranged below the fixed bottom, and the water seal tank outer chamber is located outside the water seal tank inner chamber. A wet water seal knife and a dry water seal knife are respectively arranged on the lower surface of the fixed bottom. The wet water seal knife is inserted into the water seal tank inner chamber and immersed in the water body, and the dry water seal knife is located inside the water seal tank outer chamber.
[0007] Preferably, the wet water seal knife and the dry water seal knife are made of stainless steel or other metal materials.
[0008] Preferably, the wet water seal knife and the dry water seal knife are connected to the fixed bottom by bolts.
[0009] Compared with the prior art, the embodiments of the present application mainly have the following beneficial effects:
[0010] The traditional water seal tank is divided into two chambers, namely the inner chamber of the water seal tank and the outer chamber of the water seal tank. The inner chamber of the water seal tank is filled with water, while the outer chamber of the water seal tank is not filled with water. The wet water seal knife is located in the inner chamber of the water seal tank, and the dry water seal knife is located in the outer chamber of the water seal tank to form a labyrinth seal structure. Thus, the furnace gas overflowing from the gap between the walking bottom and the fixed bottom first enters the outer chamber of the water seal tank, and will not directly wash the circulating water in the inner chamber of the water seal tank, reducing heat loss, saving energy, reducing the generation of water vapor, and preventing the generated water vapor from directly entering the furnace chamber, which can better ensure the heating quality of the billet. The furnace bottom slag falls into the outer chamber of the water seal tank and will not fall into the inner chamber of the water seal tank. It is directly scraped to both ends of the outer chamber of the water seal tank by the dry water seal knife for on-line slag cleaning, and the circulating water in the inner chamber of the water seal tank will not be greatly polluted, and there is no need to regularly drain water for slag cleaning.

The wet water seal knife 3 is inserted into the inner chamber 4 of the water seal groove and immersed in the water body, and the dry water seal knife 5 is located inside the outer chamber 6 of the water seal groove.
[0016] It should be noted that due to the high energy consumption of the existing water seal structure, and the water temperature in the water seal increases due to heat transfer in the furnace, and the evaporated water vapor enters the furnace, affecting the heating atmosphere in the furnace. Therefore, in order to solve the problems of high energy consumption of the existing water seal structure, the water temperature in the water seal increases due to heat transfer in the furnace, and the evaporated water vapor enters the furnace, affecting the heating atmosphere in the furnace, this solution divides the traditional water seal groove into two chambers, namely the inner chamber 4 of the water seal groove and the outer chamber 6 of the water seal groove.
