Analyze The Reasons And Measures Of Defects Formed in The Rolling

Analyze the causes and measures of conventional defects in the rolling process of titanium plates

The general flaws are:

1. Scratch

Reason: The guide plate, rolling track, tools and rolling are not clean, there are adhesions or angular burrs, etc., rolling scratch the surface of the titanium plate; the operation is not careful, so that they collide with each other to form a scratched surface. Measures: before rolling Check the tools, guide plates, sticks, rollers, etc., and clear out the problems in time if any problems are found; operate carefully, and don't pull them in disorder.

2. Metal indentation

Reason: The burr and tail slag on the edge of the rolling piece are pressed into the surface of the product.

Measures: Eliminate burrs and surface foreign bodies on the titanium slab in time. Cut off the cracked edge and the cracked head in time.

3. Non-metallic indentation

Reason: Poor environmental sanitation, dust and foreign matter fall on the surface of the rolling piece; after pickling, the cleaning is not clean. Measures: Do a good job of hygiene, and clean up the surface adhesion of the rolling piece in time.

4. Spoke marks

Reason: The rolling surface is severely worn, with pits, pitted surfaces, scratches, etc.; the rolling surface is pressed out by the corners of the titanium plate. Measures: If mixing marks are found, grinding or replacing the mixing marks.

5. Ma Hang Pock

Reason: There is dust and foreign matter on the surface of the pressing plate or the backing plate during the press-correction annealing. Measures: Clean the surface of the pressure plate and backing plate in time before entering the furnace.
