Description

Technical Field

[0001] This utility model relates to the field of heating equipment, and in particular to a gasket assembly for reducing water beam nodules. Background Technology

[0002] In steel enterprises, heating furnaces are a common piece of equipment. Heating equipment for heating steel billets typically has multiple water beams inside. These water beams are support beams through which cooling water flows. The purpose of the water beams is to support the steel billets placed inside the heating equipment. The steel billets do not directly contact the water beams. Multiple gaskets are often installed at the top of the water beams to separate the steel billets from the water beams. However, due to excessively high temperatures, the iron oxide scale generated by the steel billets during the heating process will fall off and adhere to the gaskets, forming nodules. These nodules accumulate and protrude, forming a pit at the bottom of the steel billet. Therefore, it is particularly necessary to develop a gasket assembly that reduces nodule formation on the water beams to reduce the pit at the bottom of the steel billet. Summary of the Invention

[0003] The purpose of this invention is to provide a gasket assembly that reduces water beam nodules, which has the advantage of reducing the pressure pit at the bottom of the steel billet.

[0004] The technical solution adopted is as follows:

[0005] A gasket assembly for reducing nodule formation in water beams, disposed at the upper end of the water beam, includes multiple L-shaped gaskets and straight gaskets.

[0006] L-shaped blocks are fixedly installed at both ends of the water beam, while I-shaped blocks are installed at the upper middle part of the water beam.

[0007] The lower end of each straight pad is provided with an arc-shaped plate, which fits the upper end of the water beam. The upper surface of the L-shaped pad is flush with the upper surface of the straight pad.

[0008] Both the L-shaped and straight-shaped pads have an arc-shaped through groove at the top, which is perpendicular to the corresponding water beam.

[0009] Preferably, both the L-shaped pad and the straight pad are made of JGCo50 material.

[0010] Preferably, both the L-shaped pad and the straight pad are cast.

[0011] Preferably, both the L-shaped pad and the straight pad are provided with an identification frame on their sides.

[0012] Preferably, the diameter of the arc-shaped through groove is 300 mm.

[0013] Compared to existing technologies, the advantages are:

[0014] In this invention, the arc-shaped plate has a large area, and the contact area between the L-shaped pad and the water beam is also large. As a result, the heat exchange area between the straight pad and the L-shaped pad and the water beam is also large. The water beam has a good cooling effect on the straight pad and the L-shaped pad, and the temperature of the straight pad and the L-shaped pad is relatively low, reducing nodule formation and reducing pressure pits at the bottom of the billet. The arc-shaped through grooves of the straight pad and the L-shaped pad simultaneously meet the furnace charging requirements of both square billets and round billets, making it highly adaptable.

[0018] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 2 As shown:

[0019] Example 1: The device is installed on the upper end of the water beam 1, including multiple L-shaped pads 2 and straight pads 4. The L-shaped pads 2 are inverted L-shapes, and the straight pads 4 are straight. The L-shaped pads 2 are fixed at both ends of the water beam 1 and are fixed to the upper end of the water beam 1 by welding. The straight pads 4 are all erected on the upper middle part of the water beam 1. The lower end of each straight pad 4 is provided with an arc plate, which is adapted to the upper end of the water beam 1, thereby fixing the straight pads 4 to the upper end of the water beam 1.

[0020] The upper surfaces of L-shaped pad 2 and straight pad 4 are flush. Both L-shaped pad 2 and straight pad 4 have arc-shaped through grooves 5 at their upper ends. The arc-shaped through grooves 5 are perpendicular to the corresponding water beams 1. The arc-shaped through grooves 5 allow straight pad 4 and L-shaped pad 2 to simultaneously meet the furnace loading requirements of square billets and round billets, making them highly adaptable.

[0021] When installing L-shaped pads 2 and straight pads 4, two L-shaped pads 2 are welded to both ends of the water beam 1. The contact area between the L-shaped pads 2 and the water beam 1 is relatively large, resulting in a large heat exchange area between the water beam 1 and the L-shaped pads 2. This provides a good cooling effect on the L-shaped pads 2, resulting in a lower temperature for the L-shaped pads 2, reducing the formation of nodules on the L-shaped pads 2, and reducing the pressure pits at the bottom of the billet. Multiple straight pads 4 are placed at the upper end of the water beam 1, with each straight pad 4 positioned between two L-shaped pads 2. The arc plate has a large area, providing a large heat exchange area between the water beam 1 and the straight pads 4, resulting in a good cooling effect on the straight pads 4, a lower temperature for the straight pads 4, reducing the formation of nodules on the straight pads 4, and reducing the pressure pits at the bottom of the billet.

[0022] Example 2: A plurality of L-shaped pads 2 and straight pads 4 are installed on the upper end of the water beam 1. The L-shaped pads 2 are inverted L-shapes, and the straight pads 4 are straight. Both L-shaped pads 2 and straight pads 4 are made of JGCo50 material and are cast. The L-shaped pads 2 are fixedly installed at both ends of the water beam 1 and are fixed to the upper end of the water beam 1 by welding. The straight pads 4 are all mounted on the upper middle part of the water beam 1. Each straight pad 4 has an arc-shaped plate at its lower end, which fits the upper end of the water beam 1, thereby fixing the straight pads 4 to the upper end of the water beam 1.

[0023] The upper surfaces of L-shaped pad 2 and straight pad 4 are flush. Both L-shaped pad 2 and straight pad 4 have an arc-shaped through groove 5 at their upper ends. The arc-shaped through groove 5 is perpendicular to the corresponding water beam 1. The diameter of the arc-shaped through groove 5 is 300 mm. The arc-shaped through groove 5 allows straight pad 4 and L-shaped pad 2 to simultaneously meet the furnace loading requirements of square billets and round billets, making it highly adaptable. Both L-shaped pad 2 and straight pad 4 have an identification frame 6 on their sides to indicate the material of L-shaped pad 2 and straight pad 4.

[0024] The specific working process is as follows: When installing L-shaped pads 2 and straight pads 4 on the water beam 1, the two L-shaped pads 2 are welded to both ends of the water beam 1. The contact area between the L-shaped pads 2 and the water beam 1 is large, the heat exchange area between the water beam 1 and the L-shaped pads 2 is large, the cooling effect of the water beam 1 on the L-shaped pads 2 is good, the temperature of the L-shaped pads 2 is low, reducing the nodules on the L-shaped pads 2 and reducing the pressure pits at the bottom of the billet. Multiple straight pads 4 are placed at the upper end of the water beam 1, and the straight pads 4 are all placed between two L-shaped pads 2. The arc plate area is large, the heat exchange area between the water beam 1 and the straight pads 4 is large, the cooling effect on the straight pads 4 is good, the temperature of the straight pads 4 is low, reducing the nodules on the straight pads 4 and reducing the pressure pits at the bottom of the billet.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
