Abstract
The invention discloses a recycling method for an investment casting waste mould shell. The recycling method comprises the steps of crushing the waste mould shell, carrying out fine grinding, screening, mixing the crushed waste mould shell with silica sol and the like. The recycling method is simple in process and convenient in manufacturing; a coating material prepared by recycling the investment casting waste mould shell can be used for coating a back layer of the investment casting mould shell, so that the production cost is saved, and pollution to the environment due to discard of the waste mould shell is avoided.
Description
Technical field
The present invention relates to a kind of recoverying and utilizing method, be specifically related to a kind of model casting and discard shell recoverying and utilizing method.
Background technology
In the production process of model casting, a large amount of discarded shells can be discharged, thrown away by as industrial refuse always.These discarded shells occupy a large amount of soils, pollute water source, soil and air, add the production cost of Enterprise Transportation and environmental protection etc. simultaneously.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of model casting to discard shell recoverying and utilizing method.
Shell recoverying and utilizing method is discarded in a kind of model casting, comprises the following steps:
(1), pulverize: shell is discarded in model casting and is ground into bulk by disintegrating apparatus;
(2), fine grinding: the shell pieces of bulk is put into grinder and carries out fine grinding;
(3), screen: the powder after fine grinding is put into screening machine and screens, filter out 100-200 object powder;
(4), mix: the powder of 60-80 weight portion step (3) gained is put into material-compound tank, unlatching is stirred in 500-800r/min and adds 25-40 weight portion Ludox and stir evenly, add 10-30 weight parts water glass, 25-30 weight portion aluminium-silica fireproof material more successively, promote speed of agitator again and stir 30min to 1000-1200r/min, after entering sand mill circular grinding with 80 eye mesh screens filtrations, namely obtain coating material.
Further describing as technique scheme:
Described aluminium-silica fireproof material is calcined kaolin or converter bauxite.
Present invention process is simple, easily manufactured, by discarding the recycling of shell to model casting, made coating material, the coating of investment casting shell backing layer can be used in, not only save production cost, and avoid and abandon the produced pollution to environment due to discarded shell.
Detailed description of the invention
Shell recoverying and utilizing method is discarded in a kind of model casting provided by the invention, comprises the following steps:
