One of the main problems of the modern world is the search for saving energy resources, namely fuel, and reducing metal consumption during heating. High-temperature heating wells are among the largest consumers of fuel. In modern conditions, there are many factors that influence the increase in the duration of the presence of metal in heating units, both technological (order of delivery according to the assortment) and external (air alarms, power outages, etc.), which leads to its settling.
At the same time, the metal is in them for a long time at temperatures above 1300°C, which leads to significant losses of metal due to overheating, melting and scale formation and increased fuel consumption, which in turn affects the increase in the cost of production.
The purpose of the research is to reduce fuel and metal losses due to overheating.
The creation and research of rational and promising modes of heating metal during long-term stay in heating wells, with the improvement of the technological process, is an urgent task.
At the article calculates the influence of the new heating regime on the specific consumption of welding slag and fuel. The developed mode is aimed at reducing the supply of metal in the zone of high temperatures above 1300 oC (quenching is carried out only once), which allows to reduce their overheating during the heating process and, as a result, to reduce the melting of ingots and reduce scale formation.
The new mode of metal heating will lead to a decrease in the temperatures that affect the metal during a long stay in the heating wells, which in turn will allow to reduce the carbon black of the metal by 1.015 kg/t, due to the reduction of the amount of slag that appears, and also to reduce costs of fuel by 2.03 kgf/t and obtain a significant economic effect on production.
Key words: fuel, heating wells, slag, heating, temperature, thermal mode, metal
