摘要: Cold rolled steel industry in type of batch annealing furnace, the mechanical properties sheet have variation by each position. The parameters temperature and time were analysed to work out source variation. This experiment is using low-carbon that cold at same reduction ratio. Then annealed applying different soaking laboratory furnace. which examined. Yield strength, Tensile %Elongation Hardness. result showed (1) Increasing could remarkably decrease yield tensile strength hardness, whereas be increased. (2) slightly effect on properties. (3) 650°C with 2 hr should applied provide close target value (4) Grain size workpieces trended grown from 610°C.The it can concluded significant annealing.
