Energy storage copper tube shrinking mold

How can a copper mold tube be optimized for a high casting speed?

To meet the demands of billet production with a high casting speed, the copper mold tube should be continuously optimized and developed based on specific process requirements. For example, mold performance could be improved by extending the length, adjusting the cooling water supply parameters, and changing the mold vibration mode.

How reformed the mold copper tube for Pangang Group Company Limited?

Zhang J F et al. reformed the mold copper tube for the Pangang Group Company Limited. The taper of the 150 mm × 150 mm billet copper tube reduced from 0.8%/m~10%/m to 0.6%/m~0.7%/m, soft water was used as the cooling water, and the temperature of molten steel in tundish reduced to 1525~1545 °C.

What is the maximum temperature of a copper tube?

It can be seen from Figure 19 that the maximum temperature of the copper tube in the 2 mm rounded water slot is 148.488 °C and the minimum temperature is 48.566 °C. The maximum temperature of the copper tube in the right-angled water slot is 146.877 °C and the minimum temperature is 48.318 °C.

What is the maximum von Mises equivalent stress of a mold copper tube?

It can be obtained from Figure 14 that the maximum von Mises equivalent stress of a 25 mm wall thickness mold copper tube is 601 MPa and the minimum von Mises equivalent stress is 35.80 MPa. The maximum von Mises equivalent stress of a 15 mm wall thickness mold copper tube is 256 MPa, and the minimum von Mises equivalent stress is 17.60 MPa.

Does Cu-Ag mold have a longer service life than deoxidized phosphorus copper?

So, the Cu-Ag mold can have a longer service life than deoxidized phosphor copper in the continuous casting process, which is conducive to the smooth operation of continuous casting production. Figure 8. The von Mises equivalent stress of copper wall in mold of different materials. (a) Deoxidized phosphorus copper material; (b) Cu-Ag material.

How does FEM improve mold life in low carbon steel?

Mold loss was reduced, and mold life was improved. Janik M et al. used the finite element method (FEM) and the commercial software Ansys to analyze the three-dimensional temperature field in the billet mold during the continuous casting of low carbon steel.
