摘要： A seal assembly is located at an entrance and/or an exit of a heat treatment furnace with a side plate for heat treating a continuously fed metallic strip. The furnace includes an elastic rotating roll which has a roll body and a roll shaft, and is engaged with an elastic pad fixed on a surface of a seal plate and the metallic strip to seal an inside of the furnace against outside air. The seal assembly includes at least two closely-set slip disks arranged in an axial direction of an end side of the roll body, and at least one elastic disk engaging the side plate of the furnace. The at least two slip disks and at least one elastic disk are fitted over the roll shaft between the side plate of the furnace on which the elastic rotating roll is rotatably mounted and the roll body of the elastic rotating roll such that the at least two slip disks and the at least one elastic disk are in surface contact with each other. In the contact surfaces present from the roll body to the side plate of the furnace, the contact surfaces between the at least two slip disks have the lowest coefficient of dynamic friction.

摘要： A method for making either a ringless annealing furnace roll or a furnace roll having a series of spaced ring for supporting a metal strip being removed from an annealing furnace. Each ring is centrifugally cast with an outer rim of a steel alloy that is relatively insoluble with respect to the alloy of the strip being transferred from the furnace, and an inner liner of an alloy that can be readily welded to a roll. The inner liner material is fused to the rim material to form a composite ring.

摘要： A seal device is provided in each comparted entrance and exit of a furnace for continuous thermal treatment of a metallic strip using a flammable atmospheric gas. The seal device is provided with seal members for sandwiching the metallic strip to seal the flammable atmospheric gas, seal hardwares each being fixed to a furnace body and pressed by the seal member, and seal mechanisms for sealing the flammable atmospheric gas from the seal member at an urgent time. A differential distribution detector having heat-receiving portions formed of a metallic pipe filled with air is placed over the whole width outside the seal member. When a leaked atmospheric gas is ignited outside the seal member, a rapid temperature increase in the heat-receiving portions is detected to give a signal, whereby running of the metallic strip is stopped, and the seal mechanism is operated to shut off the seal device from the inside of the furnace body. Then, a nitrogen gas is fed into the seal device.

摘要： Apparatus for electric arc graining the surface of a traveling electrically conductive workpiece, the surface having a substantial area. The graining is effected by a continuous loop electrode having an elongated main body portion and an elongated continuous loop tip edge projecting laterally from a general plane of the main body portion for establishing an arc between the tip edge and the workpiece surface. The arc is moved about the continuous electrode tip by elongated magnetic means located in close proximity to the electrode, the magnetic means including a continuous loop pole member spaced outwardly of and concentric with the continuous loop tip edge. A second pole member of a polarity opposite the outer pole member is located in the general center of the closed loop tip edge.
