する器具の耐用向上のためのコーティング材に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to the use of Al (melting point 660.4°C), Zn
(melting point: 419 J°C), Sn (melting point: 232.0°C), and other metals with a melting point of approximately 800°C or less, and their alloys. This invention relates to a coating material for improving the durability of coated instruments.
上記の低融点金属の溶解鋳造のための容器，器具類には
鉄合金のような金属あるいはセラミックスが使用される
。Metals such as iron alloys or ceramics are used for containers and equipment for melting and casting the above-mentioned low melting point metals.
例えば、アルミニウム合金溶解鋳造に用いるストーク，
ラドル等の器具には、強度とコスト面から一般に鋳鉄が
用いられている。For example, stalks used for melting and casting aluminum alloys,
Cast iron is generally used for tools such as ladles due to its strength and cost.

う欠点がある。However, when Fe in cast iron comes in contact with 1% aluminum melt, it forms Fe-Al alloy and melts into the aluminum melt, causing severe damage to the base material and loss of durability, and impurities in the aluminum alloy. However, there is a drawback that the quality of aluminum products deteriorates significantly because a large amount of iron is mixed in.
このため、セラミック製の器具を用いたり、また鋳鉄表
面に種々のコーティングを施すことが提案されている。For this reason, it has been proposed to use ceramic instruments or to apply various coatings to the cast iron surface.

れている。For example, JP-A-60-180657 discloses a ceramic low-pressure casting stalk manufactured by nitriding reaction sintering using metallic silicon or metallic silicon and a refractory material as raw materials, and also, Japanese Patent Publication No. 56-6772
The publication discloses a casting tool having a boron nitride coating formed on the surface of the casting tool, and further discloses a casting tool in which a coating of boron nitride is formed on the surface of the casting tool.
No. 8488 discloses holsterite. Aluminum oxide. A method of forming a ceramic protective film is disclosed in which a coating material consisting of silicon aggregate and a silicate-based solution binder is applied to the surface of a metal object heated to a predetermined temperature.

ある。補修のためには、器具交換作業に鋳造装置を停止
する必要があり、？＊修作業にも相当な時間を費やされ
る。このため、従来より高耐用で無補修期間が長く鋳造
期間の長い鋳造器具が求められていた。However, in the case of ceramics, although the contamination of impurities into the product can be avoided, the cost is more than 10 times higher than that of cast iron, and the load is low. It has drawbacks such as being easily damaged due to heat load conditions and having a relatively short service life. Also, regarding cast iron surface treatment, there is still no continuous durability.
Currently, repair work must be completed within 10 days. For repairs, is it necessary to stop the casting equipment for equipment replacement work? *Repair work also takes a considerable amount of time. For this reason, there has been a demand for cast instruments that are more durable, have a longer maintenance-free period, and have a longer casting period than before.
本発明の目的は、低融性合金との反応を抑制し、溶解鋳

本実施例に用いたコーティング材の基本構或を第１表に
示す。これに弗素化合物及びタルクを外掛けで添加し、
試験コーティング材とした。Table 1 shows the basic structure of the coating material used in this example. Add a fluorine compound and talc to this,
It was used as a test coating material.
第 １ 表
試験片は第ｌ図に示すような径２０叩φＸ長さ１００叩
の棒状浸漬器真１を用意する。この時、棒状浸漬器具１
の基材は特に制限されていないが、本実施例では基材と
して、ＪＩＳ ＦＣ ２０ の鋳鉄を用いた。Table 1 For the test piece, prepare a rod-shaped dipper stem 1 with a diameter of 20 strokes and a length of 100 strokes as shown in Figure 1. At this time, the rod-shaped dipping device 1
Although the base material is not particularly limited, JIS FC 20 cast iron was used as the base material in this example.
コーティング方法はハケ塗りにより母材表面にコーティ
ング厚１００〜２００μｍ程度に塗布する。これを室温
で養生後乾燥及び焼戊等の熱処理を加え、供試試料とし
た。The coating method is to apply the coating to the surface of the base material by brushing to a coating thickness of about 100 to 200 μm. This was cured at room temperature and then subjected to heat treatment such as drying and baking to obtain a test sample.
試験方法は、電気炉中でアルミナ坩堝に金属アルミニウ
ムを溶かし、７００℃に保持し、これに上記試験片を２
週間連続浸漬させ、試験後基材の損傷量調査及び状態観
察を行った。弗素化合物として、弗化カルシウムを用い
た場合の試験結果を第２表に示す。The test method was to melt aluminum metal in an alumina crucible in an electric furnace, maintain it at 700°C, and place two of the above test pieces in it.
The substrate was immersed continuously for a week, and after the test, the amount of damage to the substrate was investigated and the condition was observed. Table 2 shows the test results when calcium fluoride was used as the fluorine compound.
比較例１．２に示すように、弗化カルシウムの添加量が
５重量％未満ではコーティング材に脆化が著しく、コー
ティング材が破壊されアルミニウム溶湯が基材へ侵入し
激しく損傷する。As shown in Comparative Example 1.2, when the amount of calcium fluoride added is less than 5% by weight, the coating material becomes extremely brittle, the coating material is destroyed, and the molten aluminum penetrates into the base material, causing severe damage.
また、比較例３のごとく、逆に弗化カルシウム添加量が
１００重量％を超えると、おもに結合剤の不足によるも
のと思われるが良好なコーティング膜が得られず、また
耐火原料との比率の影響であろ・うが造膜性が劣化し、
膜に亀裂．剥離を生ずる。On the other hand, as in Comparative Example 3, when the amount of calcium fluoride added exceeds 100% by weight, a good coating film could not be obtained, probably due to the lack of binder, and the ratio with the refractory raw material could not be obtained. Possibly due to the influence, the film-forming properties of the mouth deteriorate,
Cracks in the membrane. Causes peeling.
これに対し、実施例１〜６に示すように、弗化カルシウ
ム添加量を５重量％以上にすることで、膜の脆化が改善
され、基材の損傷はなくなり、良好な結果となる。On the other hand, as shown in Examples 1 to 6, by increasing the amount of calcium fluoride added to 5% by weight or more, the embrittlement of the film is improved, damage to the base material is eliminated, and good results are obtained.
また、上記比較例のごとく、弗化カルシウムの添加で耐
アルミニウム性は向上するが、更にタルクの併用の系で
同様の試験を行った。その結果を第３表に示す。Further, as in the above comparative example, the aluminum resistance was improved by adding calcium fluoride, but a similar test was conducted using a system in which talc was also added. The results are shown in Table 3.
（以下、この頁余白）
実施例７〜１１より、タルクの併用によりアルミニウム
の地金付着や造膜性が向上することが判る。(Hereinafter, this page margin) From Examples 7 to 11, it can be seen that the combined use of talc improves aluminum base metal adhesion and film forming properties.
ただし、比較例５のようにタルクを過剰添加すると弗化
カルシウムと同様に造膜性が劣化する。However, if excessive talc is added as in Comparative Example 5, the film-forming properties will be deteriorated like calcium fluoride.
先の実施例９に示したコーティング材を用い、アルミニ

用が１週間前後であるのに対し、本実施例では１ケ月耐
用となり、約４倍の向上が認められた。Using the coating material shown in Example 9 above, a stalk for an aluminum alloy low-pressure casting apparatus was coated in the same manner as in the above Example, and an actual machine test was conducted. The base material of the stalk is FC 20. As a result, while the normal lifespan is around one week, this example had a lifespan of one month, an improvement of about four times.
また、アルミニウム以外として、亜鉛溶解槽の鋳鉄製測
温管に同様のコーティングを施し、実機テストを行った
結果、通常耐用の約２．５倍の高耐用が得られた。In addition, as a material other than aluminum, a similar coating was applied to a cast iron thermometer tube for a zinc melting tank, and as a result of an actual machine test, a long life approximately 2.5 times longer than normal life was obtained.
以上、低融点合金として、アルミニウム合金の場合を例
に説明したが、亜鉛合金．錫合金等においても良好な結
果が得られることを確認した。Above, we have explained the case of aluminum alloy as an example of a low melting point alloy, but zinc alloy. It was confirmed that good results could also be obtained with tin alloys and the like.
本発明のコーティング材を低融点金属の溶解鋳造用容器
，器具類に施すことにより、器具の耐用が向上し、無補
修使用期間が長くなり、途中の補修作業の手間を省略す
