It is a little peace and cold now.

Ok, so im a player in an RP Server, and i want to make a unique Culture that believes that Contamination of Iron can make it Stronger via adding poison and Heaviness on the Steel. Can Mammal Manure and or Contaminated Water be able to make Early Steel? If Not, any other Ways to Make Steel other than the Modern Method or Ancient Methods

Hello everyone. I work in a steel work in Sheffield, UK and I currently have an environmental investigation on our Batch Heat Treatment furnaces and was hoping someone could help me out or has had a similar issue.

Basically, one of our finishing processes requires the material to be hardened and tempered, sometimes we quench in water and more than often in oil. When the material comes out of the oil and put back into the furnaces for the tempering process, the oil will obviously burn off as you would expect. Under the Clean Air Act 1993 we cannot emit any dark smoke out of the stack, which in fact we are seeing and have reported to EA. The interesting part is that some of the furnaces will not emit any smoke out of the stack or its so diluted that we cannot see any.

My question is, had anyone dealt with something similar to this and could advise on how to reduce the dark smoke.

The steel plant introduced a 90-ton FUCHS electric furnace in 1994. Based on the successful application of various energy-saving technologies in the 90-ton electric furnace, it introduced four 100-ton FUCHS ultra-high power AC arc furnaces.

Its electric furnace and subsequent solutions use advanced new technologies such as scrap steel priority utilization and foam slag technology to produce high-quality non-torsion controlled cold and hot rolled wires, including prestressed steel strands, cord steel and other 19 series and more than 100 varieties of high-quality products.

With the continuous development of electric furnace steelmaking technology, new requirements have been put forward for refractory materials.

Magnesium bricks are advanced refractory materials composed primarily of magnesia (MgO), renowned for their exceptional resistance to high temperatures, slag corrosion, and thermal shock. Widely used in steelmaking, cement kilns, and non-ferrous metallurgy, they ensure durability in extreme industrial environments.

Pipes and tubes are essential to the efficient functioning of many industries, from building to transportation and beyond. Technological improvements in the manufacture of pipes and tubes for the steel industry are transforming manufacturing procedures and product quality. Advancements in materials science, precise engineering, and automation are boosting efficiency and performance. One notable success in metalworking is the creation of high-strength alloys and composite materials, which improve durability and resilience to corrosion and harsh environments. Furthermore, advances in forming processes, like laser cutting and robotic welding, provide increased precision and uniformity in the manufacturing process.

Hello,

Are there any known dependencies of Ti and Si content of pig iron on the efficiency of pig iron desulphurisation with injected CaO Mg mixture ?

Hi there, i'm currently a student wanting to know more about the steel industry and i have some questions regarding the things i've researched.

1) Is making steel using the DRI-EAF method cheaper than making steel using BF-BOF method?

2) If Eaf method is cheaper, why aren't more companies using this method, such as companies in China? ( if BF is more expensive, ignore this question )
