1, Craft Introduction

A new process for direct reduction ironmaking of low-grade iron containing materials (containing over 35% iron). The carbon emissions are 50-60% lower than traditional blast furnace processes.

Solution 1: Use our company's DC plasma electric furnace to directly melt the pressed balls into the furnace (with a power consumption of about 900 kWh per ton of raw material).

Option 2: Preheat natural gas to 1000 ℃ (about 50m ³ of natural gas is consumed for one ton of raw material). Then it is melted in a DC plasma electric furnace (with a power consumption of about 390 kWh per ton of raw material).

Smelting produces two end products, one is low-carbon pig iron (bread iron), and the other is slag, which can be sold to cement plants as clinker.

2, energy-saving principle

This process utilizes the electromagnetic stirring characteristics of a DC plasma electric furnace to increase the fluidity and thermal conductivity of the melt, resulting in uniform temperature and high yield. At the same time, by combining the advantages of a DC furnace with a power factor of up to 0.95-0.98 (arc temperature of 4000 ℃), the melted material can quickly reach its melting point, shorten the smelting time, and obtain high-quality metal.
