热轧中厚板产品质量指标主要包括力学性能和尺寸精度,但在当前激烈的市场竞争中,用户对钢板的表面质量也提出了更高要求,严格避免出现麻面、麻坑/麻点以及花斑等表面缺陷。因此,表面质量逐渐成为中厚板的主要质量指标之一,受到钢厂和下游用户的高度重视。据下游造船厂反馈,花斑缺陷严重影响到船板涂漆后的表 Hot rolled plate product quality indicators include mechanical properties and dimensional accuracy, but in the current fierce market competition, the user of the steel surface quality also put forward higher requirements, strictly avoid the emergence of Ma, Ma Hang / pitting and Pieces such as surface defects. Therefore, the surface quality has gradually become one of the main quality indicators of plate, by the steel mills and downstream users attach great importance. According to the downstream shipyard feedback, piebald defects seriously affect the ship after painting the table
