How is steel made in the "carbon neutral era"?
Fluke Iron & Steel Metallurgy Applications Brochure

McKinsey's "China's Accelerating Towards Carbon Neutrality" Steel Chapter: Carbon Emission Reduction Pathways in the Steel Industry points out that there are three main drivers of energy efficiency transformation in the steel industry, namely capacity upgrading and replacement, operational excellence, and raw material optimization, and several important levers that require special attention [1]

McKinsey expects that by 2030, about 20 million tonnes of carbon reduction potential will come from the natural upgrade of small blast furnace-converter to large blast furnace-converter.

The blast furnace includes the blast furnace body, feeding equipment, air supply equipment, injection equipment, gas treatment equipment, and slag iron treatment equipment, which cooperate with each other to form a continuous and large-scale high-temperature production process, and the temperature monitoring needs to be carried out at the top of the furnace, the hot iron ditch, the water wall, the top of the hot blast furnace, and the blast furnace air supply branch pipe to ensure the normal operation of the equipment.

Another important aspect of concern is the EAF, which will be produced using EAF scrap and will be more economical to reduce carbon emissions through green electricity. In this process, the electric furnace that uses the high temperature generated by the electrode arc to smelt ores and metals, and the temperature in the arc area is above 3000 °C, and its electrical indicators need to be monitored to prevent electrical failures.

Iron and steel metallurgy is a key industry for energy reform and manufacturing upgrading, and it urgently needs to be supported by high-standard and high-quality testing products and technologies. Fluke products are widely used in blast furnace ironmaking, converters, electric arc furnaces, continuous casting, hot rolling and other key links of steel smelting, and the solutions cover daily inspection, professional testing, intelligent automatic control, standard establishment, information integration and other fields, helping iron and steel enterprises to enhance their core competitiveness and seize market opportunities during the critical period of energy transition.

Everyone knows that THD is Total Harmonic Distortion, which is divided into voltage THD and current THD, which indicates the severity of voltage and current waveform distortion. The larger the harmonic content of the waveform, the more serious the waveform distortion and the larger the THD value. Conversely, the lower the THD value. That...

Emissivity Emissivity

Emissivity refers to the ratio of the energy radiated from the surface of an object to the energy radiated by a blackbody at the same temperature. (A blackbody is an idealized radiator that radiates all of its energy and has an emissivity of 1.00 on its surface) The emissivity of various substances is determined by the material of the object itself.
