• Prediction of blast furnace operation using online ...

    The large scale databasebased online modeling, called LOM, is a type of JustInTime modeling for blast furnace. In this paper, we propose a new type of LOM using a nonlinear local model to improve the performance of the longterm prediction. To estimate the parameter of the nonlinear local model, we use online Bayesian learning scheme with Sequential Monte Carlo. The prediction performance ...

  • Steel Production

    The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved, the processes inside the blast furnace remain the same. The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal is a key part of the coke ...

    The Crude Blast Furnace is used to make Steel, which you'll want a ton of. It also makes Slag, although that isn't as useful. The Coke Oven makes Coal Coke and Creosote Oil. Coal Coke is pretty useful, but Creosote Oil is actually required to progress; you'll need Treated Wood for a lot of things. You can make an Improved Blast Furnace after producing a bit of steel with your crude blast ...
