Testing and Simulating Study on the Solid Shell Shape of Slab Continuous Casting

Abstract

The solid shell thickness of AH36 slab with cross section of 170 mm x 1400 mm was measured by the nail-shooting test at the speeds of 1.25 and 1.35 m/min. the test positions located at the width direction of 1/2, 1/4 and 1/8. and the liquid core length and solidification ending were calculated by solidification law. Furthermore, using the software of secondary cooling simulation in slab casting to simulate the solidification process of AH36 slab, the solid shell shape and the change trend of solid shell thickness, and the temperature distribution on intrados of the slab in the width direction were studied. the results showed that the measuring results were close to the simulating results, the first solidification position at 1/4 position, and the solidification ending at 1/8 position. the research results provided a good foundation to design and optimize the secondary cooling system.
