Transcribed image text: … WebThe kinetics of growth of the layer of scale of low-carbon steel and a mild-steel were carried out on a Gleeble-3500 Thermal Mechanical Simulation System to simulate a hot finishing strip mill. An investigation of scale growth on an as-supplied surface proved that the growth of the original 21μm layer of scale decreased as the steel oxidized further.

WebNov 30, 2004 · Abstract. In this paper, hot rolling tests of low-carbon steel were carried out on a 2-high Hille 100 experimental rolling mill at various speeds and reductions. The rolling temperatures were between 1000 and 1030 °C. Nitrogen protection was used to control the scale thickness when the test samples were heated in the furnace and cooled … Web5.4.1 Hot rolling of steel. Hot rolling of a 50 mm thick C-Mn steel slab, reduced by 25% in one pass, is presented below. The slab is heated to a uniform temperature of 1050°C and cooled for 15 seconds in air. The process parameters are: roll radius 340 mm, roll velocity 22 rpm, and the friction coefficient is 0.25. symptoms of information overload
