Structure and Property of Heating WorkingQ235 Bloom by EPM Treated

Compared the structure and property of Q235 continuous casting bloom by EPM treating with no-treating after heating working, the influence of structure and prop-erty of heating working with improved and fined casting structure by EPM treating have been researched. The results shown that the structure of heating working by EPM treating is more even, and the crystal is finer than no-treating. The σ_U increases 6.9%, and α_k increases 100%.
