Temperature monitoring. temperature control in hot rolling mills. hot rolling mills are used to reheat shapes of steel to soften them enough so that they can be rolled thinner and longer througheries of rolling stands. the finished product can be eithertrip, plate, rod, bar, wire, or shape rails and hbeams.
The blast furnaces are closed. big invest ments are planned in sandviken tube mill 60, press mill 62, tube mill 63, pilger mill 64, coldrolling mills 61, 63 and 64, electric arc furnace 64, hardening plant 65 and tube mill 68. two extrusion presses are of substantial importance for seamless stainless steel tube.
The charge of raw materials is melted inurnace which, inarge tube mill, may hold up to 20 tons of metal. the furnaces primary function is to melt the copper charge, and if the raw materials are only in the form of cathode, refined ingot or home scrap,imple shaft furnace suffices. this type of furnace cannot be used to refine metal.
The mandrel mill shell is then reheated ineheat furnace so that it can complete the final rolling process and gain its final dimensions and microstructural qualities. upon exit from the reheat furnace, the tube receivesighpressure water descale, removing the iron oxide scale that formed in the reheat furnace.
