摘要: 對連鑄板坯在爐停留時間和熱軋中厚板超聲波探傷質量之間的關系進行了研究.結果表明:220mm厚連鑄板坯在爐停留時間低于3h會導致中厚板超聲波探傷合格率顯著降低;延長鑄坯在爐停留時間能夠有效提高中厚板的超聲波探傷合格率;中厚板中引起超聲波探傷不合的缺陷是珠光體帶中的微裂紋;減弱連鑄板坯的中心線偏析能夠有效提高中厚板的探傷質量.

Abstract: The relationships between the heating furnace time of casting slabs and the ultrasonic testing quality of hot-rolling medium plates were investigated. It is concluded that, (1) when the heating furnace time of 220 mm thickness casting slabs was less than 3 h, very bad ultrasonic testing quality of the plates would happen; (2) increasing the heating furnace time of the slabs could effectively improve the ultrasonic testing quality of the plates; (3) what caused the ultrasonic testing lost was micro-cracks in the pearlite band; (4) reducing the centerline segregation of the slabs could obviously improve the ultrasonic testing quality of the plates.
