Study of the temperature regimes in the heating and piercing of steel ingots to obtain thick-walled shells

This article examines aspects of the use of thermal imaging and mathematical modeling to determine temperature inside a semifinished product as it is heated and pierced on a rotary rolling mill. A scheme is devised to thoroughly examine the thermal state of metal during shaping operations, and therm...

Description
Summary:This article examines aspects of the use of thermal imaging and mathematical modeling to determine temperature inside a semifinished product as it is heated and pierced on a rotary rolling mill. A scheme is devised to thoroughly examine the thermal state of metal during shaping operations, and thermograms are obtained of the surface of metal at different moments in the piercing operation.
