How to Solve Hot Rolled Steel Defects
It is caused by severe longitudinal cracks in the steel billet, inadequate heating during rolling , and low water pressure or blocked nozzles during descaling. To prevent this, inspect steel billets for cracks , ensure proper heating, maintain high-pressure descaling systems, and control the rolling pace.
Edge cracks occur on the edges of metal sheets during hot and cold rolling due to tensile stresses induced at the surfaces from uneven heating, rolling , or quenching. They can be removed through trimming or stretch and roller leveling under tension. Alligator cracks result when metal layers separate and sheets shear in the plane, usually due to non-homogeneous material flow across the ...
Moving forward, it's essential to keep these visual contexts in mind when discussing Avoiding Cracks Caused By Rushed Rolling Sessions.
The former causes zipper cracks in the centre and the latter causes wavy edges. The remedy for zipper cracks and wavy edges lies in providing a "camber" to the rolls. They are made slightly convex in the central portion to offset the effect of deflection under rolling loads.
