摘要： Provided is a continuous annealing furnace in which the dew point of furnace atmosphere can be rapidly lowered to a level suitable for normal operation and in which atmosphere having a low dew point, which is less likely to cause pick-up defects and damages to furnace walls, is consistently achieved. Also provided is a method for continuously annealing a steel strip using the annealing furnace. A continuous annealing furnace for annealing steel strips that is a vertical-type annealing furnace configured so that part of gas inside the furnace is drawn and introduced to a refiner disposed outside the furnace including an oxygen removing apparatus and a dehumidifying apparatus, oxygen and moisture contained in the gas are removed to lower the dew point of the gas, and the gas having a lowered dew point is put back into the furnace. At least one gas inlet through which gas is drawn from the furnace into the refiner is disposed in the vicinity of the entry side of the furnace at a distance of 6 m or less in the vertical direction and 3 m or less in the furnace-length direction from the steel-strip-introduction section located at the lower part of the heating zone.

摘要： A gas seal for the material inlets (10') and outlets (10*) of reactors (1) for treating strands (7) and strips (7) of material. The openings are sealed (10) by gas curtains which are created by means of gas flows, which are oriented in a slanted position with respect to the inside of the furnace (15) and which are discharged from gas outlets (13) or nozzles. According to the invention, gas conducting bodies (11) are connected to the gas outlets (13), said bodies extending close to the strands (7) or strips (7) of material in a substantially parallel manner with respect to the surfaces of said strands (7) or strips (7) of material. The gases which are discharged out of the gas outlets (13) are guided in gas conducting areas (14), which arise between the gas conducting bodies (12) and the strands (7) or strips (7) of materials, in a targeted manner at a slightly increased pressure in the direction of the inner area of the reactor (15), thereby creating a substantially improved gas seal.

摘要： A furnace for producing oxides of lead includes an enclosure defining a furnace chamber, a feed inlet for feeding particulate lead into the chamber, and a discharge outlet for discharging the particulate lead outside the chamber. An array of horizontally disposed serially communicating tubes are arranged vertically within the chamber, communicating between the feed inlet and the discharge outlet. A rotating valve is associated with the feed inlet, for continuously feeding particulate lead into the number of tubes. Variable drive chain and sprocket combinations are associated with each of the tubes to convey the particulate lead serially along the tubes. The furnace includes electric heat tapes surrounding the tubes, for heating the particulate lead within the tubes while the lead is being conveyed along the tubes. The furnace can be used to produce red lead from leady-oxide or litharge by first supplying air or pure oxygen into the tubes. Leady-oxide is supplied at feed inlet and heated in the first tube to 1250°F to initiate the exothermic conversion of leady-oxide to litharge. Heat from the exothermic reaction occurring in the remaining tubes of the array is used to pre-heat the first tube. Litharge formed from the exothermic reaction is exposed to a lower temperature of 850° in the lowermost tubes of the array for formation of red lead. The travel rate of the litharge determines the percentage of red lead in the final product exiting the discharge outlet.

摘要： A heating furnace for a press hardening process comprises: a cylindrical heating furnace main body in which an inlet for receiving a blank steel plate from a winding coil and an outlet for discharging the blank steel plate are respectively placed on the upper and lower portions thereof and a space capable of conveying the blank steel plate is prepared therein, a conveyor which is spirally arranged in the inner circumference of the heating furnace main body in order to successively convey the blank steel plate from the upper inlet to the lower outlet, and a clamping unit which is prepared in one side of the conveyor to selectively clamp the blank steel plate. According to the present invention, the length and space occupied by the facility are farther reduced than a linear heating furnace system so the available area of a plant can be increased. There is a useful effect that product quality is improved through uniform texture variation as a result of uniformly heating the entire region of the blank steel plate being conveyed during heating. In addition, the heating time for the blank steel plate being conveyed can be shortened by increasing the heated region and in that way, productivity is improved.
