Abstract:
The objective is to design a hopper that utilized the radiative energy emitting from the open
inlet area of the electric arc furnace to preheat the scrap metal up to some temperature.
Preheating is done in various processes to reduce the power consumption and metal pre-heating
can be useful depending on the available potential of energy that is being wasted. There are
numerous configurations of preheaters, and one configuration is selected using decision matrix.
Transient thermal analysis was done to predict the scrap temperature using ANSYS Transient
Thermal Analysis, and Steady State Analysis was done to find the maximum temperature of
plate and structural members. After analyzing thermally, structural members were designed
having maximum distributed loading and change in temperature. Having huge temperature,
cross section of beams was changed to accommodate flow of water to reduce the temperature
of beams.
