| titleOfInvention | A kind of preparation method of moulding sand for casting |
| abstract | The invention discloses a kind of preparation methods of moulding sand for casting, mainly press 95 118 by aggregate, binder and plant ash:5‑8:0.5 1 mass ratio is uniformly mixed, and the aggregate is grouped as by the group of following parts by weight：45 55 parts of CRT panel glass processed material, 25 30 parts of graphite sand, 15 18 parts of magnesia, 10 15 parts of rosin rock powder, wherein the preparation method of the CRT panel glass processed material includes the following steps：（1）The CRT panel glass of recycling is crushed to grain size 3mm or less；（2）CRT panel glass after crushing is continuously stirred into 5 minutes granular panel glass derived above；（3）Above-mentioned granular panel glass is sieved.The preparation method high mechanical strength of moulding sand for casting provided by the invention, thermo-chemical stability are good, adhesive property protrudes, and gas permeability is preferable, and casting condensation rate is uniform, cast(ing) surface is not likely to produce crackle and shrinkage cavity after condensation, is particularly suitable for production quality and requires high casting. |
