Method of manufacturing stephanoporate metal honeycomb structure member

[0014] Example 1

[0015] A method for preparing a porous metal honeycomb structure. When the alloy powder used in the method is chromium-nickel, chromium-nickel-molybdenum stainless steel, the alloy powder and water-based binder prepared at a weight ratio of 80:20 Pre-mix in a mixer for 30 minutes, then mix on the mixer for 100-120 minutes to form a dough, put it into an extrusion die, and extrude under an extrusion force of <100MPa, and the extruded billet is at a temperature of <200°C Dry and vacuum sinter at a temperature of 1200-1350°C to form a porous metal honeycomb structure; the weight formula of the binder is 10% polyvinyl alcohol, 20% carboxymethyl cellulose, and 4% glycerin. Ethanol 3%, water 63%.

[0016] Example 2

[0017] A method for preparing porous metal honeycomb structure. When the alloy powder used in the method is tin bronze, 6-6-3 bronze, or iron-copper, the alloy powder prepared in a weight ratio of 60:40 and water-based adhesive The binder is pre-mixed in a mixer for 30 minutes, and then mixed on the mixer for 100-120 minutes to form a dough, which is placed in an extrusion die and extruded under an extrusion force of <100MPa. Drying at a temperature of ℃, sintering in an ammonia decomposition protective atmosphere at a temperature of 750-850℃, can be made into a porous metal honeycomb structure; the weight formula of the binder is 15% polyvinyl alcohol, carboxymethyl fiber Vegetarian 15%, glycerol 6%, ethanol 0.5%, water 63.5%.

[0018] Example 3

[0019] A method for preparing a porous metal honeycomb structure. When the alloy powder used in the method is an iron-chromium-aluminum heat-resistant alloy, the alloy powder and water-based binder prepared in a weight ratio of 90:10 are placed in a mixer Pre-mix for 30 minutes, then mix on a mixer for 100-120 minutes to form a dough, put it in an extrusion die, and extrude under an extrusion force of <100MPa, and dry the extruded at a temperature of <200°C. Vacuum or dry H at a temperature of 1250-1350℃ 2 (Dew point -60℃) sintered in an atmosphere, the porous metal honeycomb structure can be made; the weight formula of the binder is 5% of polyvinyl alcohol, 25% of carboxymethyl cellulose, 1% of glycerin, and 5% of ethanol. %, water 64%.
