The steel used for offshore platforms in various countries in the world is divided into mild steel, medium-high-strength steel and high-strength steel. At the same time, considering the stability and reliability of offshore platform components, steels of different strengths need to meet different yield ratios. In addition, due to the different parts used on the offshore platform, the thickness requirements of the steel plate are also different.
BBN Group's first blast furnace blast dehumidification system: The project started construction on May 2 and began trial operation on August 28. All data are balanced and stable, blast furnace output indicators have improved significantly, and the daily dehydration capacity of the two blast furnaces is as high as 124 tons, with a daily increase of about 200 tons TMCP NV E36 barge carrier steel, and the blast furnace is running smoothly.
The impression of most customers who have cooperated with us on the company is being professional and responsible. That mainly owe to our united and considerate team members. For example, the professional technician, the responsible QC inspector, the experienced sales person, the rigorous document maker, the patient after-sales, etc. Their selfless devotion bring the customer good experience, and bring the company good reputation.
The sulfur element (S element) comes from the ore and fuel coke of steelmaking. It is a harmful element in TMCP NV E36 barge carrier steel etc. steel. Sulfur exists in steel in the form of iron sulfide (FeS). FeS and Fe form a low melting point (985℃) compound. The hot working temperature of steel is generally above 1150 - 1200℃, so when the steel is hot working, the premature melting of FeS compound causes the workpiece to crack, which is called "hot brittleness". It reduces ductility and toughness of steel and causes cracks during forging and rolling. Sulfur is also detrimental to welding performance and reduces corrosion resistance.
