Description

Technical Field

[0001] The present application relates to the technical field of casting furnaces, and in particular to a side-flow casting furnace. Background Art

[0002] When making parts, a casting furnace is often needed to cast molten steel.

[0003] At present, the pouring method of the vacuum degassing furnace is to pour into the furnace under non-vacuum state, and the pouring is done at the upper mouth of the furnace. Because the slag inclusions in the molten steel in the furnace are all on the surface of the molten steel, the slag inclusions can easily enter the casting during pouring, thereby reducing the quality of the product and generating a large amount of waste. When pouring under non-vacuum state, the molten steel comes into contact with the air and easily absorbs the gas and moisture in the air, making the molten steel easy to melt, thereby causing shrinkage holes and cracks in the casting.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0029] Reference Figure 1-5 A side stream casting furnace comprises a bottom plate 1, a frame 2 is fixedly installed on the top of the bottom plate 1, two positioning bars 3 are symmetrically fixedly installed on the top of the frame 2, the inner walls of the two positioning bars 3 are slidably connected with convex bars 4, and the tops of the two convex bars 4 are fixedly installed with protective covers 5, a furnace body 6 is installed on the top of the bottom plate 1, the outer edge of the furnace body 6 is fixedly connected with a fixed pipe 7, the outer bottom of the fixed pipe 7 is fixedly connected to the pouring port 8, a through hole 9 is opened on the inner wall of the fixed pipe 7, a plug rod 10 is inserted into the inner wall of the through hole 9, and the outer side of the plug rod 10 is fixedly connected to the output end of the electric telescopic rod 13, a heating element 14 is fixedly installed on the inner wall of the furnace body 6, a base brick 15 is fixedly installed on the inner bottom of the furnace body 6, and an induction coil 16 is fixedly installed on the top of the base brick 15.

[0030] See Figure 1 and Figure 2 The inner walls of the two positioning strips 3 are provided with sliding grooves that are adapted to the shape of the convex strips 4. The two convex strips 4 are slidably connected to the inner walls of the sliding grooves. The bottoms of the protective cover 5 on both sides away from the convex strips 4 are in contact with the top of the frame 2, so that the protective cover 5 can be easily installed to the top position of the frame 2, thereby forming a seal on the furnace body 6, ensuring that the furnace body 6 can be in a vacuum state in the inner cavity of the frame 2 and the protective cover 5.

[0031] See Figure 3 - Figure 5 The outer edge of the furnace body 6 is fixedly connected to the side plate 11, and the bottom of the side plate 11 is fixedly connected to the fixed plate 12. The bottom of the fixed plate 12 is fixedly connected to the outer edge of the electric telescopic rod 13, so that the electric telescopic rod 13 can be positioned to ensure the stability of the output shaft of the electric telescopic rod 13 during the stretching movement, and to ensure that it will not shake or deviate in position.

[0032] See Figure 5 The outer edge of the induction coil 16 fits with the inner wall of the heating element 14 so that the heating element 14 can transfer heat to the molten steel, ensuring the uniformity of the molten steel when heated and ensuring that it will not dry out in the inner cavity of the induction coil 16.

[0033] See Figure 2 and Figure 3 The outer edge of the furnace body 6 is threadedly connected to a cover plate 17, and a handle 18 is fixedly installed on the top of the cover plate 17, so that the inner cavity of the induction coil 16 can be sealed, ensuring that foreign matter and impurities from the outside will not enter the inner cavity of the induction coil 16 through the opening above the induction coil 16 and come into contact with the molten steel, thereby improving the sealing and protection effect.

[0034] See Figure 3 The outer edge of the handle 18 is fixed with several anti-slip protrusions, which increases the gripping strength of the user's hand when turning the handle 18, thereby increasing the force point of the hand and improving the convenience of turning the handle 18 to remove the cover 17.

[0035] See Figure 1 The through hole 9 is communicated with the inner wall of the pouring port 8, and the outer diameter of the plug rod 10 is adapted to the inner wall diameter of the through hole 9, so that the molten steel in the inner cavity of the induction coil 16 can be discharged to the outside through the through hole 9 and the pouring port 8 for pouring operation. The molten steel is poured from the bottom, the quality of the molten steel is very pure, and it is poured under a vacuum state. The molten steel does not contact the air, and the outer diameter of the plug rod 10 is adapted to the inner wall diameter of the through hole 9, so that when the plug rod 10 is inserted into the inner wall of the through hole 9, the inner wall of the through hole 9 is sealed to ensure that the molten steel will not be easily discharged to the inner wall of the pouring port 8 when pouring is not needed.

[0036] See Figure 1 The outer edges of the frame 2 and the protective cover 5 are coated with a galvanized layer, which can improve the aesthetics and corrosion resistance of the outer edges of the frame 2 and the protective cover 5, and ensure that they will not be easily corroded when placed in various temperature environments, thereby increasing their service life.

[0037] Working principle: When using this device, first take the protective cover 5 and slide the two ridges 4 at the bottom to the inner walls of the two slide grooves, and then stably install the protective cover 5 to the top of the frame 2, so as to form a seal with the furnace body 6, ensuring that the furnace body 6 can be in a vacuum state in the inner cavity of the frame 2 and the protective cover 5. Then, you can turn the handle 18 to tighten the cover 17 to the outer edge of the furnace body 6, and seal the inner cavity of the induction coil 16 to ensure that foreign matter and impurities from the outside will not enter the induction coil 16 through the opening above the induction coil 16. The cavity is in contact with the molten steel, which improves the sealing and protection effect. When pouring is required, the electric telescopic rod 13 can be driven first to drive the plug rod 10 to move away from the inner wall of the through hole 9, and then the molten steel in the inner cavity of the induction coil 16 can be discharged to the outside through the through hole 9 and the pouring port 8 for pouring. The molten steel is poured from the bottom, the quality of the molten steel is very pure, and it is poured under a vacuum state. The molten steel does not contact the air. After the pouring is completed, the electric telescopic rod 13 is driven again to drive the plug rod 10 to slide on the inner wall of the through hole 9, thereby blocking the inner wall of the through hole 9 to ensure that the molten steel cannot be discharged.
