Investigation of Theeffect of the Rate of Issuance of Slabsand Blanks on the Unevenness of the Thermal State and Metal Carbon Monoxide During Heating in Methodical Furnaces

The paper analyzes the factors influencing the uneven heating of metal in methodical furnaces. Special attention is paid to the study of the influence of the uneven rate of delivery of steel slabs and blanks from methodical heatingfurnaces on their thermal condition and losses with carbon monoxide. A previously developed deterministic mathematical model was used as a research tool to determine the dynamics of the thermal state and metal carbon monoxide during heating in methodical furnaces. To solve this problem, the model has been modernized, its functionality has been expanded in order to take into account the uneven movement of the heated metal in the furnace. It was found that with a relatively low effect of the uneven rate of discharge on the final thermal state of the slabs, carbon monoxide can change by 1.5 times, due to the influence of the temperature-time factor.
