Abstract
A method of calculating heat input to an alloying furnace which includes heat input means for use in the production of hot galvanized band steel comprising conveying a band steel of a selected steel variety through the alloying furnace and forming a plated deposition on the band steel in the alloying furnace comprising an alloyed layer of iron and zinc, establishing a formula defining a correlation between heat input and at least the steel variety, the plated deposition and the conveying speed of the band steel, inputting information which relates at least to the steel variety, the plated deposition, and the conveying speed, determining the heat input on the basis of the information inputted, and using the determined heat input to control the heat input means of the alloying furnace thereby controlling the formation of the iron and zinc alloyed layer plated deposition.
