Process control temperature homogeneity of the products in a steel reheat furnace and reheating furnace.

摘要

Process control temperature uniformity of steel products (2), especially of slabs or billets, in a reheat furnace (1) equipped with side burners, according to which process are operated side burners in all or nothing and It is regulating the operating time and stop each burner to obtain the desired temperature, characterized in that chosen as side burners burners extended flame (B1-B4), that are operated these burners to a next regime to maximum or at the maximum rate, and because the firing order of the burners (B1-B4) is chosen so that the removed and circulation of the fumes to reduce the hot spot is favored flame and a better homogeneity is obtained temperature of the furnace walls and products.
