The intelligent scrap rating system can complete the rating of the whole vehicle gauge material type, and is more capable of measuring multiple thickness mixed material types, and rating and deducting weight according to the weight proportion of different thickness material types in the whole vehicle. The system has the…

The furnace lining of acid electric arc furnace is acid refractory material, and acid slag is made during steelmaking.Acid electric arc furnace can be used for smelting carbon steel, low alloy steel and certain high alloy steel, but not for smelting high manganese steel. Compared with alkaline arc furnace steelmaking,…

According to a recent report released by the International Energy Agency, global carbon dioxide emissions from energy combustion and industrial processes will increase by 6% year-on-year to 36.3 billion tons in 2021. Global carbon dioxide emissions will increase by 6% in 2021, in sync with global economic growth of 5.9%.…

The lubrication is a key operation in hot rolling process, it influences service life of the rolling mill and the quality of rolled piece. Reduce friction coefficient In the hot rolling process, the friction coefficient of roll and rolled piece is generally about 0.35 under no lubrication, and it can…

There are probable occurring problems when disc shear runs. Continue to cut Generally, this is caused by serious wear or too much clearance, the shearing edge gap should be calibrated or the blade should be replaced; it may also be that the shearing edge locks the hydraulic nut or the…

During the billet heated, operators should take measures to prevent following case happening. Overheating When the steel billet is heated for a long time at high temperature, it is very easy to overheat. The overheating phenomenon of steel billet is mainly manifested in the excessive growth of the microstructure grains…

It is quite important to operate a new induction furnace correctly, that could affect the service life of the induction furnace. The new furnace should be continuously smelted as much as possible to avoid thermal shock damage caused by intermittent melting and hot and cold, and generally should be continuously…

According to incomplete statistics, 2021 global new steel production capacity (excluding China) nearly 90 million tons mainly concentrated in Asia, Europe, including new long steel capacity of 14.4 million tons , new plate capacity of 14.02 million tons, new crude steel production capacity of about 53.27 million tons, new semi-finished…

Solidification of continuous casting billets will release much heat that divided three parts: superheat of steel: the heat released from the cooling of the steel from the pouring temperature to the solidification temperature; latent heat of solidification: the heat released from the cooling of the steel from the liquid phase temperature…

Why is nitrogen added to the steelmaking process? The effect of nitrogen on steel is mainly in the area of heat treatment and process properties. Both nitrogen and carbon can be incorporated into iron as an interstitial linkage to iron, and unlike carbon,  nitrogen is a very good austenitic stabilizing…
