Description

Technical Field

[0001] The utility model relates to the technical field of cleaning oxidized iron scale in a water seal groove at the bottom of a heating furnace, in particular to an automatic cleaning device for cleaning oxidized iron scale in a water seal groove of a steel rolling heating furnace. Background Art

[0002] In the metallurgical industry, steel rolling lines, particularly those in the water seal tank between the heating furnace and the rolling mill, are prone to damage. The water seal tank seals the interface between the heating furnace and the rolling mill, preventing high-temperature gas leakage while also collecting and removing impurities such as iron oxide scale (red scale). The accumulation of iron oxide scale can compromise the sealing performance of the water seal tank, leading to gas leakage and disrupting the normal operation of the heating furnace. Therefore, developing a device that can automatically clean iron oxide scale from the water seal tank is crucial for improving production efficiency and ensuring equipment safety.

[0003] Currently, steel rolling heating furnaces are generally designed with a water seal trough and a water seal knife to automatically clean the oxidized iron scale in the heating furnace to the tail of the heating furnace, transport the iron scale to the bottom of the furnace through a slag drop pipe, and then manually clean the oxidized iron scale and transport it to a designated location. However, the existing technology has problems such as daily cleaning, high labor intensity, high operating temperature, and poor working environment.

[0004] Therefore, there is an urgent need to design an automatic cleaning device for iron oxide scale in the water seal tank of a steel rolling heating furnace to solve the problems of high labor intensity, high operating temperature and poor working environment. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide an automatic cleaning device for iron oxide scale in the water seal tank of a steel rolling heating furnace.

[0007] Specifically, the furnace bottom slag ditch is a water trough with a built-in tilt angle, and a hanging hook is provided at one end of the furnace bottom slag ditch that is higher than the horizontal line.

[0008] Specifically, the hanging hook is arranged on the furnace bottom slag groove, and is used to be hung on the bottom of the heating furnace to provide an inclination angle for the furnace bottom slag groove when the inclination of the furnace bottom slag groove itself is insufficient.

[0009] Specifically, the slag chute is arranged on the outside of the heating furnace and at the lower part of the slag outlet of the water seal chute. The slag chute is fixed to the bottom end wall of the heating furnace through a fixed shaft, and the lower end of the slag chute flows to the slag ditch at the bottom of the furnace.

[0010] Specifically, the fixed shaft is arranged at the lower part of the center position of the slag chute.

[0011] Specifically, the slag flushing water pipe is arranged at a port on a side of the furnace bottom slag ditch that is higher than the horizontal line, and the slag flushing water pipe flushes water into the furnace bottom slag ditch.

[0012] The utility model has the following beneficial effects:

[0013] The utility model designs an automatic cleaning device for iron oxide scale in the water seal tank of a steel rolling heating furnace: a slag flushing groove is designed at the furnace bottom on the charging side of the heating furnace, which is connected to the main slag flushing groove for steel rolling and the steel rolling vortex well; a slag dropping groove is designed in the water seal tank, which leads to the slag groove at the furnace bottom, and slag flushing water is designed in the slag groove at the furnace bottom, so that the iron oxide scale in the water seal tank of the heating furnace falls into the slag flushing groove through the slag dropping groove, thereby achieving low labor intensity and simple operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural diagram of an automatic cleaning device for iron oxide scale in the water seal tank of a steel rolling heating furnace.

[0016] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely further describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] Example 1:

[0018] like Figure 1 As shown, an automatic cleaning device for oxidized iron scale in the water seal trough of a steel rolling heating furnace comprises a furnace bottom slag ditch 1, a slag dropping trough 2 and a slag flushing water pipe 3. The furnace bottom slag ditch 1 is arranged at the lower part of the heating furnace 4, one end of the furnace bottom slag ditch 1 leads to the steel rolling vortex well 6, and a slag flushing water pipe 3 is provided at the other end of the furnace bottom slag ditch 1. The slag dropping trough 2 is arranged at one end of the heating furnace 4, and the bottom end of the slag dropping trough 2 flows to the furnace bottom slag ditch 1.

[0019] When the heating furnace 4 produces iron oxide scale, it automatically falls off into the water seal groove 5 at the bottom of the heating furnace 4, and the iron oxide scale flows out into the slag chute 2 through the slag drop port 5.1 on the water seal groove 5. The slag chute 2 is used to guide the iron oxide scale into the furnace bottom slag ditch 1 below the heating furnace 4. A fixed shaft 2.1 is provided at the lower center of the slag chute 2. The fixed shaft 2.1 is used to fix the slag chute 2 to the end wall 7 of the furnace bottom of the heating furnace 4. The iron oxide scale that falls into the furnace bottom slag ditch 1 flows down to the vortex well 6 due to the slope of the furnace bottom slag ditch 1. The furnace bottom slag ditch 1 is also provided with a hanging hook 1.1. When its own angle is insufficient, it can be hung on the water seal groove 5 by the hanging hook 1.1 to increase the inclination angle of the furnace bottom slag ditch 1. In addition, a slag flushing water pipe 3 is provided at the higher end of the furnace bottom slag ditch 1. The slag flushing water pipe 3 flushes water into the furnace bottom slag ditch 1, thereby providing power for the iron oxide scale in the furnace bottom slag ditch 1 and specifying the flow direction.
