Description

technical field [0001] The invention relates to a temperature control system and a control method for hot-rolled metals, in particular to a temperature control system and a control method for rolling aluminum / aluminum alloy coils. Background technique [0002] With the development of aluminum and aluminum alloy processing technology, the application fields of aluminum materials in the national economy are becoming more and more extensive, and higher requirements are put forward for the performance of aluminum materials. Temperature is an important process factor in the hot rolling process of aluminum and aluminum alloy coils, which directly affects the properties of the coils and the quality of the subsequent cold rolling process. At present, most of the hot rolling processes of aluminum and aluminum alloys do not control the rolling temperature, or the control method is simple, and the execution effect is not good, so the performance of the coil is directly affected, and it...
