Problems solved by technology

As we all know, the common defects of products produced by casting production methods are pores, trachoma, loose structure, etc. Therefore, it is difficult for the upper and lower rings of the crystallizer produced by casting to meet the actual use requirements in terms of essential sealing

Embodiment 1

[0020] A forging process for a crystallizer includes the following steps:

[0021] The first step: blanking: use 6061 material, the casting rod with an outer diameter of 120mm as the raw material, and blank it to 80mm through a metal band sawing machine;

[0022] The second step: heating: place the bar in the mesh belt furnace for 2 hours to raise the temperature to 480°C, keep the temperature of the bar at 460°C, and keep it for 2 hours;

[0023] Step 3: Forging: Use a 1600t electric screw press to forge the bar twice to form it. The forming size is subject to the specific production drawings.

[0024] Step 4: Punching: Use a 400T closed single-point press to punch the forging. The diameter of the punch is 120mm, and a 122mm round hole is punched on the bar.

[0025] Step 5: Solid solution: Put the formed forgings into the material frame, and the number of formed forgings in the material frame shall not exceed 400 pieces. The formed forgings are quenched in a vertical quenc...

Abstract

The invention relates to a forging technology used for a crystallizer. By means of the forging technology, loosened areas and air holes which are small in size in a forge piece can be closed in the forging process, conditions of air holes, sand holes and structure loosening which frequently occur in original forging production can be avoided, the compactness and mechanical property of a product can be improved, compared with an original crystallizer, the mechanical property can be improved by approximately 30%, and the using requirements are greatly satisfied.

Description

technical field [0001] The invention relates to the field of forging, in particular to a forging process for a crystallizer. Background technique [0002] The upper and lower rings of the crystallizer must bear huge water pressure during use, so the upper and lower rings of the mold must be required to have a good seal. Once there is a local water leakage, the cooling speed and uniformity of the casting rod will be reduced. If the production requirements are not met, the casting rod will be bent and deformed, which will greatly reduce the yield of casting production and increase the cost of production and use. As we all know, the common defects of products produced by casting production methods are pores, sand holes, loose structure, etc. Therefore, it is difficult for the upper and lower rings of the crystallizer produced by casting to meet the actual use requirements in terms of essential sealing. Contents of the invention [0003] In view of the above-mentioned exis...
