一种铸坯皮下质量的检测方法
摘要：
本发明属于冶金工业的技术领域，具体的涉及一种铸坯皮下质量的检测方法。该种铸坯皮下质量的检测方法，包括以下步骤：（1）冷却：对铸坯进行水冷或缓冷；（2）烧除：待铸坯冷却后，对铸坯的表面进行烧除，烧除铸坯表面的氧化铁皮及部分表面；其中烧除的深度为1～3mm；（3）清理：用水冲洗铸坯的烧除部位，并用氧气进行吹扫；（4）观察：通过铸坯的烧除部位观察铸坯皮下质量缺陷。该检测方法适用于在线或离线快速检查铸坯皮下质量。
摘要（英）：

The invention belongs to the technical field of metallurgical industries and in particular relates to a method for detecting the casting blank skin quality. The method for detecting the casting blank skin quality comprises the following steps: (1) cooling, namely performing water cooling or slow cooling on a casting blank; (2) burning-off, namely burning-off the surface of the casting blank after the casting blank is cooled, and burning-off the oxide scale and partial surface of the casting blank surface, wherein the burning-off depth is 1-3mm; (3) cleaning, namely washing the burn-off part of the casting blank by using water, and purging by using oxygen; and (4) observing, namely observing the casting blank skin quality defects by virtue of the burning-off part of the casting blank. The detection method is suitable for rapidly checking the casting blank skin quality in an on-line or off-line mode.
