The steel industry, as one of the higher carbon emitting industries, is decreacing crude steel production on order to realize high quality development. The addition of vanadium to steel strengthens the bar and contributes to the high quality development of the steel industry. Vanadium containing steel bars can help the…

1.Digital yard Using 5G network to read digital yard point cloud data, real-time display of yard 3D outline, pile material type and weight, as well as the operation status of pile and pickup equipment, to achieve accurate management. 2.Belt mornitoring Unmanned correction and inspection solution connects HD camera, correction switch…

The EAF steelmaking energy will consume more energy after adding the DRI, there are the following reasons. DRI melting increased energy consumption, the lower the DRI metallization rate, the higher the FeO content, and the reduction reaction of FeO in electric furnace steelmaking is a heat absorption reaction. Vein stone…

Carbon neutrality has a far-reaching impact on the global steel industry, that will involve the following five aspects controlling total scale, regulation energy mix, increasing investment, affecting global steel trade and raising prices of steel products. In October 2020, the IEA’s (International Energy Agency) World Energy Technology Outlook 2020 –…

At present DRI is mainly used at high quality steel grade such as oil industry casing, drill pipe; spring steel, bearing steel, rotor of steam turbine generator, gun barrel and steel for aerospace and atomic energy industry. The output of DRI increased year by year, the 12 countries counted by…

China raised export tariffs on ferrochrome and high-purity pig iron to 40 percent and 20 percent. This adjustment is aimed at pushing industrial upgrading and high-quality development in the steel sector. The Ministry of Finance and the State Taxation Administration jointly announced that China will scrap export tax rebates on…

HSS rolls have excellent wear resistance, and their service life in the finishing stand of hot mill is 3~6 times that of high chromium iron rolls. Uneven temperature distribution on the roll surface of HSS rolls will easily produce uneven thermal expansion, resulting in oxide film shedding and affecting the…

China’s state reserves authority on Wednesday released a total of 150,000 tons of copper, aluminum, and zinc from the national reserves to alleviate burdens on businesses over rising raw material costs. This is the third batch of releases to the market. Previously, China has released a total of 270,000 tons…

In the continuous rolling process, there is differential metal flow rate two adjacent rolling mills, when the metal flow of the rear mill is greater than of the front mill, workpiece between two mills will be subject to pulling force the front mill, this force is usually called tension. Tension acts on the workpiece and can reduce resistance of the workpiece along rolling direction, thus the flow…

In late July, a meeting of the Political Bureau of the Communist Party of China Central Committee had carbon emissions high on the agenda amid the worsening climate crisis that has seen extreme weather conditions across the globe. The Political Bureau meeting urged a faster rollout of a national action plan…
