摘要： A method for making a grain-oriented electric steel sheet, particularly for producing magnetic transformer circuits, comprising continuously casting steel into a steel slab or strip containing less than 0.1 % of carbon, 2.5-4 % of silicon and at least the elements aluminium, nitrogen, manganese, sulphur and copper for forming normal growth inhibiting precipitates; heating the slab or strip; hot-rolling the slab or strip to give a sheet 1-5 mm thick; hot-coiling the hot-rolled sheet; annealing the hot-rolled sheet; cold-rolling to a final thickness of less than 0.5 mm; performing primary recrystallisation and decarburisation annealing in a moist atmosphere; applying magnesia (MgO) to at least one side of the decarburised sheet; performing final secondary recrystallisation and purification annealing; applying an insulating coating and performing final coating curing annealing. The method is characterised in that, after the slab or strip has been produced, the steel comprising 0.02-0.09 wt % of carbon, 2.5-4 wt % of silicon, 0.027-0.17 wt % of manganese, 0.007-0.020 wt % of sulphur, 0.010-0.030 wt % of aluminium, 0.004-0.012 wt % of nitrogen, and 0.06-0.50 wt % of copper, with the balance being iron and impurities, is heated to a temperature higher than 1200 DEG C but no higher than 1300 DEG C, and when the hot-rolled sheet has been produced, the hot-rolled sheet is coiled at 500-700 DEG C.

摘要： A method for producing steel in an electric arc furnace comprising a vessel containing a molten steel bath, a roof covering the vessel, and one or more roof electrodes inscribed within a cylinder. According to the method, an oxygen-containing gas in the form of gas jets is blown into the vessel towards the surface of said bath so that the areas where the jets impinge on the surface do not overlap with said electrode or said cylinder. The method is characterised in that said jets are blown in from the upper portion of the furnace and penetrate to a shallow depth in said bath. A steel plant electric arc furnace comprising a vessel (1) for containing molten steel (2), a roof (3) covering the vessel (1), and one or more roof electrodes (4, 5) inscribed within a cylinder, as well as means for blowing jets (12, 13, 14) of an oxygen-containing gas into the vessel (1) towards the surface of the steel (2), so that the areas where the jets (12, 13, 14) impinge on said surface do not overlap with said electrode or said cylinder, said means consisting of nozzles (9) built into said roof (3), is also disclosed.

摘要： A device including a sampling circuit with a sampling probe (5), a gas analyser (21) and a pump (15) for feeding a gas mixture sample from the probe into the analyser, as well as a filter assembly (10) downstream from the probe. The pump (15) is located downstream from the filter assembly and the pump discharge side is connected via a connecting duct (19) to the analyser and via an escape duct (16) to an outlet. The gas mixture to be analysed is sampled through the filter assembly (10) at a high flow rate substantially higher than the flow rate to the analyser (21), and the remaining flow is removed without passing through the analyser. The device is useful for analysing dust-laden gases, particularly flue gases from electric steel plants.
