Abstract

In the all processes of steel production, a lot of heat is created; recovering and using this heat can save on natural resources and costs. The purpose of this paper is to describe an executive method and its impact on the amount of energy efficiency in continuous casting.In this paper, the amount of recovered heat from continuous casting in the pre-shear section has been investigated. To absorb this heat, a similar collector was made of solar collector collectors (using the equipment at the West Alborz Steel Company). After installing the collector at the desired location and setting up the circulating water system, 5216 kcal/h heat was recovered; according to this amount, 0.65 m³/h can be saved for natural gas consumption. After the experiment, we compared the data with the result of a numerical method and the results of other researchers. Then, due to operator and space constraints, the recommended system for recovering heat was designed. By generalizing the numerical method in the result of the experiment, we were able to estimate the amount of heat of the proposed system and provide the benefits of it. Eventually, the recovered heat of 12 m² collector area will be equal to 121086 kcal/h. At all stages, the temperature of the billets surface is estimated using thermography
