Today, Globe Caster Summarized several common defects of steel plate, the specific content is as follows:

1. Roll printing: It is a group of irregularities with periodicity, basically the same size and shape, and irregular appearance and shape.

2. Surface inclusions: There are irregular point-shaped block or strip-shaped non-metallic inclusions on the surface of the caster steel plate, and the color is generally reddish brown, yellowish brown, off-white or gray-black.

3. Iron oxide scale: generally adhered to the surface of the caster steel plate, distributed on part or all of the surface of the plate, it is black or reddish-brown, and its pressing depth varies from deep to shallow.

4. Uneven thickness: The thickness of each part of the caster steel plate is inconsistent. It is called uneven thickness. Any caster steel plate with uneven thickness is generally too large. The thickness of the local caster steel plate exceeds the specified allowable deviation.

5. Pockmarks: There are partial or continuous pits on the surface of the caster steel plate, which are called pockmarks, with different sizes and different depths.

6. Bubbles: There are irregularly distributed circular convex hulls on the surface of the caster steel plate, sometimes in a maggot-like linear shape, with smooth outer edges and gas inside; when the bubbles are broken, irregular cracks appear; Some air bubbles are not convex, after being leveled, the surface is bright, and the shear section is layered.

7. Folding: There are partially folded double-layer metal scales on the surface of the caster steel plate. The shape is similar to the crack, and the depth is different, and the cross section generally shows an acute angle.

8. Tower shape: the upper and lower ends of the steel coil are not aligned, and one circle is higher (or lower) than the other circle, which is called a tower shape.

9. Loose coil: the steel coil is not tightly coiled, and the gap between layers is called loose coil.

10. Flat coil: The end of the steel coil is elliptical, which is called flat coil, which is prone to occur in softer or thinner steel coils.

11. Cross-knife bend: The two longitudinal sides of the caster steel plate bend to the same side, resembling a cross-knife.

12. Wedge shape: The caster steel plate is thick on one side and thin on the other. Seen from the cross section of the caster steel plate in the width direction, it looks like a wedge, and the degree of the wedge is large or small.

13. Convexity: The caster steel plate is thick in the middle and thin on both sides. From the transverse end face of the caster steel plate in the width direction, it is similar to the arc shape, and the degree of the arc is large or small.
