Welding procedure of ESP continuous casting stainless steel crystallizer water tank

Abstract

The invention discloses a welding procedure for an ESP continuous casting stainless steel crystallizer water tank. The welding procedure comprises the steps that S1, a first head part and a second head part are obtained through welding; s2, the bottom plate is welded to a welding tool; s3, the first inner side plate and the second inner side plate are transversely arranged along the upper surface of the bottom plate and are welded with the bottom plate; the first head part is welded to the first inner side connecting plate, and the second head part is welded to the second inner side connecting plate; s4, a first outer side connecting plate is longitudinally arranged along the upper surface of the bottom plate, and the first connecting plate is welded with the bottom plate and the first head part; s5, welding the first cover plate and the first water channel, and tempering to remove stress; and S6, the whole ESP continuous casting stainless steel crystallizer water tank is subjected to tempering destressing. The tool assembly is adopted to control the deformation of the heated stainless steel material, and the sealing performance of the water tank adopting the welding process is better.

Description

technical field [0001] The invention relates to a water tank, in particular to a welding process for an ESP continuous casting stainless steel mold water tank. Background technique [0002] With the development of the times, the market demand for high-quality steel is increasing day by day, and the application of electromagnetic technology in continuous casting production lines is more and more extensive; electromagnetic technology can effectively improve the quality of steel billets, usually electromagnetic equipment is installed inside and outside the mold water tank, due to traditional The carbon steel water tank is magnetic and interferes with the magnetic field. Therefore, the role of the non-magnetic stainless steel mold water tank is becoming more and more obvious; on the one hand, the stainless steel material will not affect the magnetic field, and on the other hand, it has excellent corrosion resistance. The welding deformation of carbon steel materials is small, so...

Problems solved by technology

[0002] With the development of the times, the market's demand for high-quality steel is increasing day by day, and the application of electromagnetic technology in continuous casting production lines is becoming more and more extensive; electromagnetic technology can effectively improve the quality of steel billets. Usually, electromagnetic equipment is installed inside and outside the water tank of the mold. Due to the traditional The carbon steel water tank is magnetic and interferes with the magnetic field. Therefore, the effect of the non-magnetic stainless steel mold water tank is becoming more and more obvious; on the one hand, the stainless steel material will not affect the magnetic field, and on the other hand, it also has excellent corrosion resistance. The welding deformation of carbon steel materials is small, and tooling is not required, and the assembly process can be reduced, and the blank welded parts only need to be tempered once to remove stress. If the shape is out of tolerance or water leakage occurs, the repair cost is also low, but stainless steel The amount of shrinkage and deformation of materials welded is several times that of carbon steel, and the control of welding deformation is difficult, requiring the help of tooling and reasonable assembly processes, and the product production cycle and cost are much longer than carbon steel products.
