Characteristics and advantages
Significant environmental benefits: capable of processing various industrial waste and scrap metals,
reducing landfill volume and environmental pollution. Meanwhile,
compared to traditional smelting methods, the emission of waste
gas, wastewater, and waste residue during the production process of
resource recycling electric furnaces is significantly reduced.
High resource utilization rate: It can efficiently recover valuable metals and other useful
substances from waste, achieve resource recycling, improve resource
utilization efficiency, and save primary resources.
Energy utilization optimization: Some resource regeneration electric furnaces adopt advanced
energy-saving technologies, such as efficient heating systems and
waste heat recovery devices, which reduce energy consumption and
improve energy utilization efficiency. For example, the exhaust gas
from a fully enclosed industrial silicon electric furnace can be
used for power generation, and the recovered energy is
considerable.
High production flexibility: It can flexibly adjust process parameters and production
processes according to different raw material and product
requirements, adapt to various types of resource recycling
projects, and can handle waste of different grades and
compositions.
Technological development trends:
Large scale and high-efficiency: In order to improve production efficiency and reduce costs,
resource recycling electric furnaces are showing a trend of
large-scale development. Large electric furnaces have the
characteristics of high power, high furnace temperature, and large
heat output, which are conducive to improving the efficiency and
quality of resource regeneration, while also facilitating
mechanization and automation operations.
Intelligent control: With the help of advanced sensor technology, automation control
technology, and computer information technology, real-time
monitoring and precise control of the electric furnace production
process can be achieved. Through intelligent systems, energy
allocation, equipment collaboration, and production processes can
be optimized to improve production efficiency, product quality, and
energy utilization, while reducing labor intensity and production
costs.
Green and low-carbon development: In the context of the "dual carbon" goal, resource recycling
electric furnaces will pay more attention to green and low-carbon
development. On the one hand, by improving processes and equipment,
energy consumption and carbon emissions can be further reduced; On
the other hand, we need to strengthen the recycling and utilization
of carbon resources in waste, and explore new paradigms for
low-carbon metallurgy.
