摘要： A cylinder heater useful in fabricating sleeves for high pressure pump liners comprises a support rotatably supporting a hollow circular cylinder having a metallic powder layer contacting a portion of its inner surface. A vibration sensor indicates vibration of the cylinder, and at least one temperature sensor indicates at least one temperature of the cylinder. At least one circumferential induction heating coil around the cylinder is positionable via the support along the longitudinal axis of cylinder rotation. Longitudinal position and power output of at least one heating coil, and cylinder rotational speed, are adjusted by a controller communicating with the support, the vibration sensor, at least one temperature sensor, and at least one heating coil. Controlled heating of the cylinder and the metallic powder layer results in a stratified abrasion-resistant fused metallic layer on the cylinder's inner surface. The fused layer may be honed to make a liner sleeve.

摘要： The present invention relates to alloys having substantially uniform aggregate distribution, a method of making such alloys, and centrifigally cast members made from such alloys. The alloys of the present invention utilize aggregates of tungsten carbide, vanadium carbide and titanium carbide so formulated to allow them to be uniformly distributed throughout the alloy matrix.

摘要： A low alloy nickel-manganese steel consists essentially of carbon 0.18-0.23 weight percent, manganese 0.70-0.90 weight percent, silicon 0.20-0.35 weight percent, chromium 0.40-0.60 weight percent, nickel 0.40-0.70 weight percent, molybdenum 0.15-0.25 weight percent and the balance iron. The steel is especially well suited for use as a backing material for bimetallic cylinders prepared by the centrifugal casting process. The backing material has improved stability at the temperatures employed during centrifugally casting a layer of a lining alloy within a cylinder of the backing material. The backing also has improved weldability and less tendency to develop residual bending stresses under the temperatures and pressures encountered during manufacture and use of the cylinder.

摘要： A wear and corrosion resistant alloy for lining cylinders used in extrusion and injection molding machines comprises tantalum carbide admixed with a nickel-cobalt base alloy. The cylinder lining is preferably prepared by placing a quantity of the alloy in the cylinder and capping the ends of the cylinder. The cylinder is then heated above the melting point of the alloy and spun at a high rate of speed to centrifugally coat the inner surface of the cylinder. The cylinder's end caps are then removed and the lining finished to the correct internal diameter and finish by conventional lath and hone means. The tantalum carbide added to the base alloy has an affinity for carbon and tends to reduce the free carbon in the final matrix producing a lining which has desirable hardness and corrosion resistance throughout the thickness of the lining.
