The Bessemer process involved blowing air through molten iron, which removed impurities and carbon from the iron. For society the benefits will include durable products, local jobs, reduced emissions, and the conservation of raw materials for future generations. The most significant steel invention of these was the so-called Bessemer process, which was invented by Henry Bessemer in 1856. Pre-consumer recycling from the steelmaking and manufacturing processes will decrease due to increased process efficiencies and collaboration between steelmakers and their customers to reduce yield losses. The weight of many steel products will be reduced, losses will be minimised, and the already high recycling rate for steel will increase, resulting in more recycled steel to make new steel products. In the sustainable future, new economic models will maximise the value of raw materials by encouraging practices such as reuse and remanufacturing. Steel – the permanent material in the circular economyĪs a permanent material which can be recycled over and over again without losing its properties, steel is fundamental to the circular economy. Successful steelmaking must operate within these frameworks and continue to explore new sustainable ways forward into the future. Therefore, as we look to the future, governments and society must make informed decisions, using a life cycle approach, on where and how to sensibly add extra rules and restrictions. But steelmaking is not isolated - it is governed by many laws, rules, regulations and restrictions. Butt welding the pipe into the box tube would work but the transition from square to round woud be better with a flange.Steel is 100% recyclable with no downgrading in quality, which makes steel the most recycled material in the world. The other end of the 6" pipe meets with an 8 inch square, 3/8 inch, box tube at bottom angle of 20 degrees right side of vertical.Īnother issue will be a flange that will go from the 8 inch square tube to the 6 inch diameter pipe.
This 8 inch to 6 inch reduction elbow should be commercially available but I need to get the data into an Inventor file.īeing able to change the diameters, example 8 inch to 6 or 10 inch upper and 4 or 8 inch lower would be a bonus. Possibly 8 inch if the height of the 8 inch part of the elbow was 11 inches above the XY axis ((d=8 + r=3) = 11) or 12 inches (see below from commercial reduction elbow) I am not sure of the elbows radius from the junction of the XY axis.
