Embodiment Construction

[0011] Used to make porous metal fillers, the components in weight percentage are as follows: β-quartz sand 74%, β-quartz powder 5%, sodium-based activated bentonite 5%, plant ash 2.5%, graphite powder 2%, inorganic salt 0.5% , diatomaceous earth 3%, common clay 3%, bauxite 2%, red clay 1%, yellow clay 1%, crucible mud 1%, neutral water 15%.

[0012] Prepare the filler according to the above weight percentage, stir it evenly, dry it, dip it, fill it into the prepared mold after drying, press and seal it with an exhaust plate, heat it to 670°C, and prepare the molten metal Pouring step.

[0013] Further, the molding in step 1 is to shape the filler into the required specific size and shape in a special ball forming machine.

[0014] The above is only a preferred embodiment of the present invention, for those of ordinary skill in the art, without departing from the technical principle of the present invention, some improvements can also be made, and these should also be regarde...

Abstract

The invention relates to a filler for manufacturing porous metal manufactured with a filler pouring method and a filling method for the filler. The filler for manufacturing the porous metal comprises the following components including beta-silica sand, beta-quartz powder, sodium-based activated bentonite, plant ash, graphite powder, inorganic salt, kieselguhr, common clay, bauxite, red clay, yellow clay, crucible mud and neutral water. The filler is prepared according to the proportion and is evenly stirred, dried, coated in a soaking manner and dried to be arranged into a manufactured die in a filling manner, a sealing opening is compressed through an exhaust plate, heating is carried out, and pouring of metal liquid is prepared. A pure natural raw material is adopted in the filler, taste and toxin are avoided in the pouring process, environmental protection is achieved, pollution is avoided, repeated recycling can be achieved, resources and cost are saved, the refractoriness is high, collapsing after pouring is prone to occurrence, cleaning is facilitated, the filler does not have a reaction with metal liquid, and the performance of the porous metal material is better guaranteed.

Description

technical field [0001] The invention relates to the field of casting, in particular to a filling material for porous metal made by filling material pouring method and a filling method for the filling material. Background technique [0002] Porous metals, as a new type of structural and functional materials, have received extensive attention in recent years and have been applied in many fields. There are many methods for preparing porous metals, such as casting methods, powder metallurgy methods, deposition methods, etc. Among them, the casting method is a relatively mature method for the industrial production of porous metal materials. However, the overall structure of the porous metal produced by the traditional casting method is a closed hole, and the size of the cavity is uneven, which affects its mechanical properties. Contents of the invention [0003] The object of the present invention is to solve the deficiencies of the above-mentioned technical problems, and pro...
