Abstract
The invention discloses a preparation method a for FS residue auxiliary material for mold (core) sand. The FS residue auxiliary material for the mold (core) sand is prepared by obtaining residues through fermenting and hydrolyzing wood and rice hulls taken as original auxiliary materials during preparation and the FS residue is for short. The FS residue provided by the invention is used for casting production, can be added into fired mold sand, wet mold sand and sodium silicate-bonded sand to mold and prepare core after mixing, is suitable for producing multi-types of cast steel, cast iron and non-ferrous castings, is good in combination property, such as high wet strength, good surface stability, good collapsibility and deformability and the like, and besides, is low in cost, convenient for popularization and application in casting production.
Description
Technical field
The invention belongs to casting technology field, be specifically related to a kind of auxiliary material of casting type (core) sand.
Background technology
At present, the auxiliary material of types (core) sand more used in Foundry Production, often can only improve single performance index in a certain respect, sometimes, a certain performance indications improve, and other performance indications are affected.
Summary of the invention
In order to overcome the above-mentioned technical problem that prior art field exists, the object of the invention is to, the preparation method of the FS slag auxiliary material of a kind of type (core) sand is provided, improve overall performance.
The preparation method of the FS slag auxiliary material of casting type (core) sand provided by the invention, comprise following process: after brewageing, those wooden classes, rice hulls class material are fermenting raw materials, residue after hydrolysis, wear into smalls or powdery, be called for short FS slag, the preparation method as the FS slag auxiliary material of casting type (core) sand presses following proportions: raw material 100%, binding agent: conventional amount used, FS slag: 0.5 ~ 10%, water: add appropriate water according to the different sand of preparation.
Preparing process: raw material+FS slag mixed grind 2 ~ 5 minutes+binding agent (in right amount) mixed grind goes out to grind 8 ~ 10 minutes (adding suitable quantity of water on demand), or its conventional temperature sand technique.
The preparation method of the FS slag auxiliary material of casting type (core) sand provided by the invention, its beneficial effect is, FS slag is the residue after brewageing production, and cost is low, and this residue has normal temperature caking property and pyrolytic.Utilize this characteristic can improve type (core) sand hygrometric state and dry strength, the collapsibility of molding sand after cast can be improved, again because these residues are softer therefore can be used as core sand to improve deformability when metal freezing shrinks; Doing type (core) sand auxiliary material with FS slag can make water-glass sand green compression strength bring up to > 0.05MPa by original < 0.02MPa, dry compression > 1.3MPa, gas permeability > 100.Specimen surface stability 96.5 ~ 97.5%; Through 1000
0after C high temperature, residual strength is reduced to < 0.8MPa by > 1.3MPa.
Detailed description of the invention
Below in conjunction with an embodiment, the preparation method of the FS slag auxiliary material of casting type (core) sand provided by the invention is described in detail.
Embodiment
The casting of the present embodiment preparation method of the FS slag auxiliary material of type (core) sand, comprise the following steps: the fermentation of brewing industry timber, hydrolytic residue are clayed into power and made FS slag, by the mixed molding sand processed of following ratio: the FS slag of 2.5%, the quartz water glass sand of 100%, be dry mixed ten minutes, go out to grind the electric agent creeper tread of cast, dimensions 2000 × 80 × 150mm, material is potassium steel, pouring temperature 1620 ~ 1650
0c.
Claims (1)
1. cast the preparation method of the FS slag auxiliary material with type (core) sand for one kind, it is characterized in that: comprise following process: rear wooden class will be brewageed, rice hulls class material is fermenting raw materials, residue after hydrolysis, wear into smalls or powdery, be called for short FS slag, as the auxiliary material of casting with type (core) sand, by following proportions: raw sand 100 parts, binding agent: conventional amount used, FS slag: 0.5 ~ 10 part, water: add appropriate water according to the different sand of preparation; Preparing process: raw sand+FS slag mixed grind 2 ~ 5 minutes+binding agent, mixed grind goes out to grind for 8 ~ 10 minutes.
