Abstract
A kind of casting menaccanite, titanium-smelting slag, chromium smelting slag.Menaccanite is a kind of natural ore particle.Titanium-smelting slag or chromium smelting slag then are the high-melting-point slags that forms in smelting process at titanium alloy or evanohm.Said menakamite or titanium-smelting slag or chromium smelting slag, make binding agent with resin, make type, core compound, (match) with coating with said type, when the core compound comes the casting large-scale thick-walled casting, can obtain good surface quality (roughness is 25～50 grades), type, core also easily shake out.Said ore in sand form or smelting slag, aboundresources, price is lower.
Description
Invention belongs to the casting raw material.
At present, the large thick-wall foundry goods, often adopts zircon sand or chromite sand, and is equipped with good coating to improve the surface quality of foundry goods in order to prevent the liquid metals infiltration.But the zircon sand valency is expensive, is 10 times of selected quartz sand; And chromite sand, domestic resource shortage mainly relies on import.
Invention is to utilize all big, moderate menaccanite of domestic reserves and output or titanium-smelting slag or chromium smelting slag to be Modeling Material, comes production high-quality heavy castings, and menaccanite is a natural ore particle.Titanium-smelting slag or chromium smelting slag then are all kinds of high-melting-point slags that titanium alloy or evanohm form in smelting process.Said ore in sand form or smelting slag all need be made the granularity that casting requires.
Essence of an invention is, with menaccanite or titanium-smelting slag or chromium smelting slag, is equipped with suitable binding agent (resin, waterglass), makes casting with type, core compound.Make casting mold or core with said compound.Said type, core have higher refractoriness, and at high temperature (more than 900 ℃) produce slight solid-phase sintering, can set up bigger high temperature sintering intensity.When casting large-size castings, can resist the long-time heat effect of high-temperature liquid metal.Said type, core have the little characteristics of coefficient that expand of splashing concurrently, thus the infiltration of energy impedance liquid metal, thus the surface quality of raising foundry goods.
The chemical analysis and the performance of menaccanite and titanium-smelting slag, chromium smelting slag see Table 1.
The physical and chemical performance of three kinds of materials of table 1
| Al 2O 3 | SiO 2 | CaO | Cr 2O 3 | TiO 2 | The consumption acid number | Refractoriness | Capacity | |
| Menaccanite titanium-smelting slag chromium smelting slag | － >70 >75 | <2.5 | - 9.0 2.9 | - - 12.9 | >48 20 - | 5.8 11.4 25.6 | >1400 >1710 >1750 | 2.3 1.88 1.95 |
Do the thick and large casting pouring experiment respectively with menaccanite, titanium-smelting slag, chromium smelting slag, all obtain 25～50 grades of surface roughnesses (suitable) with chromite sand, the non-oxidation phenomenon, the collapsibility of type, core is better than chromite sand.Said menaccanite, titanium-smelting slag, chromium smelting slag price not high (seeing Table 2) are used the present invention in Foundry Production, have tangible economic benefit and social benefit.
The valuation at cost of three kinds of materials of table 2
| The name of an article | Menaccanite | Titanium-smelting slag | Chromium smelting slag | Chromite sand | Zircon sand | Selected quartz sand |
| Unit price (unit/ton) | 240 | 20～30 | 100 | 240 | 1000 | 100 |
Illustrate
Example 1. ironcastings prescription of mixed materials %
Table 3 ilmenite resin sand prescription
| Menaccanite (granularity 50/100) | Resin | Curing agent (accounting for amount of resin) |
| 100％ | 1.5-2.5% | 70-100% |
Add curing agent when mixing system earlier, after add resin, mixed after moulding immediately or coremaking (up time is 10～20 minutes).Model or core box must the brush releasing agents.For the thick type of spy, core, do facing sand with above-mentioned compound, molding in 2～3 hours behind the consolidation treats that type, core solidify brush (water base or alcohol radical) coating after 24 hours, and thickness is greater than 1mm, and after the drying, mould assembling is immediately poured into a mould.
Example 2, steel-casting prescription of mixed materials
Table 4 titanium-smelting slag, chromium smelting pulp water glass sand prescription
| Titanium-smelting slag (45/75 order) | Chromium smelting slag (45/75 order) | Water-glass sand (CO 2Sclerosis) |

| 100％ | 4～5％ |
Add titanium-smelting slag or chromium smelting slag during mulling earlier, mixed 1 minute, add waterglass then, mixed 3～5 minutes, molding and core making just can shake out.Use CO
2Gas hardening or curing agent are from hard.Behind the brushing paint, the drying steel-casting of just can casting.
