Experimental Study on Refractory Weathering Steel Cold-Rolled Sheets Recrystallization Annealing

Abstract:

In refractory weathering steel cold-rolled sheet production process, the grains are elongated along the rolling direction, which will lead to the change of mechanical properties of sheets. Recrystallization annealing is an important process in the production of cold-rolled sheets. Therefore, research on recrystallization temperature and determining the recrystallization annealing time are important for the production of cold-rolled sheets. By measuring the hardness at different annealing temperatures and metallographic structure observation, obtained the refractory weathering steel of reduction rate of 66.7% recrystallization temperature is 650°C; By measuring the temperature of 700°C hardness under different annealing time and metallographic structure analysis, when recrystallization annealing time is 1 hour plasticity and strength of cold rolled sheet fits well, with excellent comprehensive mechanical properties.
