Adaptive heating system for temperature distribution during warm rolling of magnesium alloy strips

Abstract

The invention discloses an adaptive heating system for temperature distribution during the warm rolling of magnesium alloy strips. The system includes a pedestal, a heating assembly, a middle displacement adjustment mechanism, edge displacement adjustment mechanisms and a controller; the heating assembly is arranged on the pedestal in a supported manner, and are arranged in the width direction ofa magnesium alloy strip; the heating assembly at least includes a middle heater and edge heaters arranged on the two sides of the middle heater; the middle heater is provided with middle temperature measurement instruments and a middle displacement sensor; the edge heaters are provided with edge temperature measurement instruments and edge displacement sensors; the middle displacement adjustment mechanism adjusts the spacing between the middle heater and the middle part of the magnesium alloy strip; the edge displacement adjustment mechanisms adjust the spacing between the edge heaters and theedge parts of the magnesium alloy strip; and the controller is connected to the middle heater, the edge heaters, the middle temperature measurement instruments, the middle displacement sensor, the edge temperature measurement instruments, the edge displacement sensors, the middle displacement adjustment mechanism and the edge displacement adjustment mechanisms.

Description

technical field [0001] The invention relates to a heating system, in particular to a heating system in the warm rolling process of magnesium alloy strips. Background technique [0002] Magnesium alloy materials are known as "green engineering structural materials in the 21st century" due to their light weight, high specific strength, good shock absorption, good machinability, good anti-electromagnetic interference performance, and easy recycling. The material industry has broad application prospects. [0003] At present, the continuous high-strength rolling of magnesium alloy strips is difficult. Magnesium alloy strips are prone to cross stripes at room temperature and cause strip breakage. For magnesium alloy strips, uncoiling and coiling at room temperature are easy Microcracks lead to coil breakage, and transverse grooves will also appear during coil rolling, resulting in many defects and even coil breakage. Through research, it is found that magnesium alloy has poor fo...
