Abstract: PURPOSE: A brake drum is provided to constrain bending of the brake drum in bimetal effect and to prevent partial wearing of a lining and extend life of the lining by forming increasing grooves for thermal expansion of an outer surface to an inner surface of a lining contact portion. CONSTITUTION: A brake drum(10) includes increasing grooves(11d) for thermal expansion of an outer surface between an inner surface(11a) and the outer surface(11b) of a lining contact portion(11). Thereby, difference thermal expansion between inner and outer surfaces is minimized by increasing thermal expansion of the outer surface due to high temperature. Increasing grooves for thermal expansion of an outer surface are arranged toward a side surface of the lining contract portion in separating from each other at regular intervals. A diameter(D1) of the increasing groove for thermal expansion of the outer surface is larger than a diameter(D2) of a lining(40) to receive a width of the lining. Increasing grooves for thermal expansion of the outer surface are formed to be inclined to the outer surface and to be a triangle shape. Therefore, bending of the brake drum in bimetal effect is constrained, partial wearing of a lining is prevented and life of the lining is extended by forming increasing grooves for thermal expansion of the outer surface to the inner surface of a lining contact portion.

Title: Cleaning using welding lances and blasting media
IPC: B08B7/02
Filed: 2000-02-11
Abstract: It is possible to clean high temperature (over 400, e. g. over 1000, degrees F) surfaces in a time and cost efficient manner by using a liquid-cooled ceramic welding lance to direct (at super-atmospheric pressure) a blasting media at the surfaces to be cleaned. The blasting media is preferably combustible at the temperature of the environment surrounding the surfaces, and may include one or more organic agricultural abrasive materials (preferably black walnut shells) as the sole or primary constituent. Blasting may be practiced by directing the media at the surfaces to be cleaned at a pressure of between about 40-100 psi, for example continuously for as long as is necessary (e. g. more than 30 minutes), without any need to remove the lance from the environment. The method is desirably practiced to clean, while in operation or in situ, metal surfaces having scale buildup which adversely affects the ability of the metal surfaces to transfer heat, reheat tubes, process tubes, furnace surfaces, or the like.
