Heating, soaking, slow cooling, quick cooling, overaging process.

Description

technical field [0001] The invention relates to a strip steel continuous annealing process simulation device. Background technique [0002] One link in the strip steel production process is the annealing process, and the large-scale strip steel continuous annealing production line has become the main process for producing high-quality strip steel. The research and development of strip steel continuous annealing process is the guarantee to continuously improve the quality and output of strip steel products, reduce costs and develop new products. Simulating the strip continuous annealing process is an important means to research and develop the continuous annealing process. The main processes in the continuous annealing production process of strip steel include heating, heat preservation, slow cooling, rapid cooling and overaging treatment. The process curve is as follows figure 1 shown. [0003] There are two types of strip continuous annealing simulators currently in use:...

Problems solved by technology

The vertical strip steel continuous annealing simulation device 3' can better simulate the process of strip steel continuous annealing, but the vertical strip steel continuous annealing simulation device 3' is bulky and complex in configuration. 305' is placed in the lower part of the cooling chamber 304', which has two defects: one is that as the test progresses, the temperature in the cooling chamber 304' will gradually increase, which will affect the cooling speed; the other is that the temperature of the overaging chamber 305' itself It is difficult to maintain uniformity, and more importantly, the vertical strip continuous annealing simulator 3' uses nitrogen for the cooling process, which makes it difficult to increase the cooling rate, and the maximum cooling rate can only reach about 50°C / s. steel very bad

[0006] Moreover, the above two strip continuous annealing simulation devices are imported from abroad, and the cost of introduction is very high
