WebOpen this example in Overleaf. This LaTeX code produces: \[ \int\limits_0^1 x^2 + y^2 \ dx \] By convention, superscripts and subscripts in L a T e X are created using the characters ^ and _ respectively; for example, the exponents applied to \(x\) and \(y\) in the code fragment above. Those characters can also be used with mathematical symbols, such as the … WebGenerally, the AOD is combined with the EAF to produce the stainless steel and the raw materials of the EAF are only the scrap and the ferro-alloy. In this way, the power consumption of the EAF (about 450 kwh/t) is higher and the melting duration of the EAF (75 min to 80 min) is longer. To further decrease the power consumption of the EAF and ...
