我厂层板高压容器的内筒,都用20K 钢板制造,它不允许有任何缺陷存在。为了确保产品质量,要求所有的20K 钢板必须用超声波百分之百地进行探测。为了达到良好的声耦合,钢板表面的氧化皮需要进行喷砂处理,然后涂上机油逐点进行探测。为了除去喷砂工序、提高工作效率、减轻劳动强度、节约国家资金、保障工人同志的人身健康,我们从1959年以来曾设计了几 I plant the inner cylinder of high pressure vessel, are made of 20K steel, it does not allow any defects exist. To ensure product quality, all 20K steel plates must be 100% probed with ultrasound. In order to achieve a good acoustic coupling, the oxide scale on the steel surface needs to be sandblasted, and then coated with oil to detect point by point. In order to remove the blasting process, improve work efficiency, reduce labor intensity, save the state funds and protect the personal health of the workers, we have designed a few since 1959
