Abstract：For preventing the edge cracking produced in hot-rolling grain-oriented silicon steel，some measures are adopted: controlling ，oxygen concentrate and hold time in atmosphere when slab heating above 1200℃，adjusting reduction and rolling temperature of roughing mill，carrying out width reduction and brink heating，changing deformation energy of material and inhibiting brink fish scale -type defect. Results show that these are effective for decreasing the formation of edge cracking.
