What Are Hot Rolled Steel Plate Defects?

Hot rolled steel plates are widely used in various industries. However, they can sometimes have defects. One common defect is surface roughness. In a manufacturing plant, a worker might notice that the surface of the hot rolled steel plate isn't as smooth as it should be. This could be due to problems during the rolling process, like improper lubrication or uneven pressure.

Another defect is the presence of cracks. Picture a construction site where workers are examining the hot rolled steel plates they received. They might find small cracks on the plates. These cracks can occur because of rapid cooling during the production process or due to impurities in the steel.

Shape distortion is also a problem. For example, in a metal fabrication shop, when they try to use a hot rolled steel plate for a specific project, they find that the plate is not flat or has an irregular shape. This can be caused by incorrect rolling techniques or improper handling after the rolling process.

How to Detect Hot Rolled Steel Plate Defects?

There are several ways to detect these defects. Visual inspection is the most basic method. Workers can simply look at the surface of the steel plate carefully. For instance, in a steel warehouse, an inspector can easily spot obvious surface roughness or cracks just by using their eyes.

Another method is ultrasonic testing. In a quality control laboratory, technicians can use ultrasonic waves to detect internal defects. If there are hidden cracks or voids inside the hot rolled steel plate, the ultrasonic waves will be affected, and the technicians can identify the problems.

Questions and Answers
