[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with illustrations and specific embodiments.

[0023] like Figures 1 to 3As shown, the utility model proposes a slag protection device for preventing slag rolling of steel ingots, comprising a support frame, the support frame is arranged on the steel ingot, and is used to provide a support platform, the support frame comprises a support part 1 and a hanging ring 2 arranged on the support part 1, and one end of the support part 1 extends outward to the outside of the steel ingot;

[0024] The fixing unit is arranged on the support frame, and the support frame is limited by the cooperation of the fixing unit and the steel ingot. The fixing unit includes a first fixing part 3 and a second fixing part 4, and the first fixing part 3 matches the outer wall of the steel ingot, and the second fixing part 4 matches the inner wall of the steel ingot. The support part 1 is fixed to the steel ingot by the cooperation of the first fixing part 3 and the second fixing part 4. The fixing unit is composed of the first fixing part 3 and the second fixing part 4, and the fixing effect is achieved by a certain form of engagement. When the first fixing part 3 and the second fixing part 4 act together, they can form a stable support structure to firmly fix the support frame on the steel ingot; the stability of the support frame is enhanced, and the loosening or falling off of the support frame due to vibration or impact during use can be effectively prevented.

[0025] In this embodiment, two support parts 1 are provided, and the multiple support parts 1 are arranged alternately with each other. The ends of the support parts 1 are located on the top surface of the steel ingot, and the support parts 1 arranged alternately with each other form a support frame.

[0026] In this embodiment, a plurality of hanging parts 5 are provided on the hanging ring 2. The hanging parts 5 are recessed inwardly along the hanging ring 2. The hanging wire is arranged on the hanging parts 5. The hanging wire is limited by the hanging parts 5, which can effectively prevent the hanging wire from sliding or falling off during operation.

[0027] In this embodiment, the support part 1 and the hanging ring 2 are both made of stainless steel. Stainless steel has high strength and good toughness. The support part 1 needs to bear the weight of the steel ingot. The high strength characteristics of stainless steel can ensure that the support part 1 is not easily deformed or broken.

[0028] In this embodiment, the top end of the first fixing portion 3 is fixedly connected to the supporting portion 1 by welding. This connection method ensures that the connection between the first fixing portion 3 and the supporting portion 1 is firm and reliable. The bottom end of the first fixing portion 3 extends downward, and a fixing groove matching the outer wall of the steel ingot is provided on one end of the first fixing portion 3, which can better contact with the outer wall of the steel ingot to ensure that the fixing portion can fit tightly on the outer wall of the steel ingot, thereby fixing the steel ingot and preventing displacement or shaking.

[0029] In this embodiment, the top end of the second fixing part 4 is fixedly connected to the supporting part 1 by welding, the bottom end of the second fixing part 4 extends downward, and one end of the second fixing part 4 is provided with a fixing groove 2 matching the inner wall of the steel ingot.

[0030] The use process and principle of the utility model are as follows: first, place the support frame on the steel ingot, ensure that one end of the support part 1 extends outward to the outside of the steel ingot, so as to provide a stable support platform for the entire device, and then use the fixing unit to limit the support frame, and fit the bottom end of the first fixing part 3 to the outer wall of the steel ingot, and match the outer wall of the steel ingot through the fixing groove 1 to achieve a snap-fit ​​fixation; similarly, fit the bottom end of the second fixing part 4 to the inner wall of the steel ingot, and match the inner wall of the steel ingot through the fixing groove 2 to achieve a snap-fit ​​fixation. The first fixing part 3 and the second fixing part 4 work together to firmly fix the support frame on the steel ingot, and then install the hanging wire on the hanging part 5 of the hanging ring 2. Since the hanging part 5 is recessed inward and limits the hanging wire, the stability and safety of the hanging wire can be ensured. After completing the above steps, the device has been fixed on the steel ingot, and the device will effectively prevent the problem of slag rolling in the steel ingot. Through the above steps, the protective slag hanging device for preventing slag rolling in the steel ingot can be conveniently and safely installed on the steel ingot, and play an important protective role.
