摘　　要：炼钢企业对于钢坯的质量检测有多种形式,分有损检测和无损检测,无损检测又有射线检测和超声检测。比较传统的无损检查是采用射线检测,由于采用射线检测需要放射源,存在一定的安全稳定性,以及放射源价格高等诸多问题,作为对传统检测方法的一种补充,采用超声检测技术与检测装置的设计与实践,此技术具有检测无损、高效、安全性高的特点。there are many kinds of quality inspection methods for steel-making enterprises,some of which will damage the shell.Compared with the traditional non-destructive inspection,it adopts the radiographic inspection.Because the radiographic inspection needs the radioactive source,there are many problems,such as certain safety and stability,and the high price of the radioactive source.This paper is a supplement to the traditional inspection method,the design and practice of the ultrasonic inspection technology and the inspection device for the thickness of solidified shell and the position of the solidified end in the secondary cooling zone of continuous casting.This technology has the function of inspection It is nondestructive,efficient and safe.
