The paper discusses an engineering procedure, which enables the automation of the process of calculating furnace heating and thermostatic control parameters of hot-charged steel slab blanks under the rational heat treatment conditions. During hot charging, the blanks coming out of a continuous casting machine at an average temperature of about 1,000°С are placed inside the heating furnaces in the hot condition, which results in a considerable decrease of their heating time, incremental reduction of specific fuel consumption, and lowering of the metal oxidation level. The procedure allows calculating the required duration of heating of the slabs loaded into the furnace in the hot condition with a sufficient degree of simplicity and accuracy and without the use of nomograms. It also allows determining the required duration of thermostatic exposure (i.e., soaking of heated slabs under adiabatic conditions) to equalize the temperature profile over the slab cross-section. The provided relationships can be used to determine the heating duration for slabs with different thicknesses depending on the temperature at which they were charged into the furnace.

计算热装板坯炉膛加热和恒温控制条件的工程程序

本文讨论了一种工程程序，该程序可以在合理的热处理条件下实现热装钢坯坯料炉加热和恒温控制参数计算过程的自动化。热装时，从连铸机出来的毛坯平均温度在1000°С左右，放入加热炉内处于热态，加热时间显着减少，比燃料消耗量逐步降低，降低金属氧化水平。该程序允许在不使用列线图的情况下以足够简单和准确的程度计算在热条件下加载到炉中的板坯所需的加热持续时间。它还允许确定所需的恒温暴露持续时间（即，在绝热条件下加热板坯的保温）以均衡板坯横截面的温度分布。所提供的关系可用于确定不同厚度板坯的加热持续时间，具体取决于它们装入炉中的温度。
