Scrap cleaning equipment improves the melting process, obtaining benefits such as reducing the consumption of energy, raw materials, refractories and electrodes.
At the same time, this type of equipment will allow better process automation and greater respect for the environment.
The main objective of the installation of this machinery is to reduce energy consumption in the electric arc furnace. The installation of a scrap preparation system allows the applied energy to be concentrated solely on the fusion of iron-based materials. This avoids the energy expenditure that currently occurs in heating loose hearth and refractories, plastic and rubber elements, cellulose and non-ferrous materials that accompany scrap metal.
THE CLEANING PROCESS
The basic process to separate and remove the sterile and nonferric metals that come mixed up with the scrap, before introducing it into the electric arc furnace can be described as follows:
This kind of installation has been designed to process from 80 to 150 tons of scrap per hour, depending on the scrap qualities.
The operation of this plant is fully automatic, with control through a PLC and a fault display. This display can show a synoptic chart with the current status of the plant.
The plant includes all the protection systems and safeties necessary for correct operation.
