PREDICTION METHOD OF THE YIELD STRESS AT ELEVATED TEMPERATURE FOR THE PLATE HOT LEVELING

摘要

The present invention is the high-temperature yield strength as a prediction method, the size of slab, the chemical component and size receiving step of slab receive process condition on the basis of room-temperature yield strength and (YP 20) of the calibration temperature of prediction (YP 20) prediction, the heat correction of chemical component and operating condition for plate room-temperature yield strength, then the thermal calibration device room-temperature yield strength before (T) and input step (YP 20) and temperature coefficient use calibration temperature (T) (T coefficients) step to predict and the high-temperature yield strength prediction method for predicting that a steps prediction normal temperature yield strength (YP 20) and temperature (T coefficients) high-temperature yield strength provide the calibration for electric furnace as the product of (YP temperature) includes.
