【発明の詳細な説明】
〔産業上の利用分野〕
本発明は、ｍ製スリーブの内側にセラミックス円筒を嵌
装した、例えば、射出成形機用耐摩耗耐蝕性加熱シリン
ダー等を製造する場合のような、鋼部材にセラミックス
部品を固定する方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to manufacturing a wear-resistant and corrosion-resistant heating cylinder for an injection molding machine, etc., in which a ceramic cylinder is fitted inside a m-made sleeve. The present invention relates to a method for fixing ceramic parts to a steel member.
、セラミックスは金属材料に比較して優れた耐摩耗性と
耐蝕性を示す反面、きわめて脆いと云う欠点を有してい
る。このため、セラミックスからなる部品を機械的強度
が要求される部分へ適用するに当たって、焼ばめ或いは
鋳ぐるみ等によりセラミックスを鋼で補強したものが用
いられている。Although ceramics exhibit superior wear resistance and corrosion resistance compared to metal materials, they have the drawback of being extremely brittle. For this reason, when applying ceramic parts to areas where mechanical strength is required, ceramics reinforced with steel by shrink fitting or casting are used.
しかしながら、焼ばめ法で補強されたセラミック部品は
、その使用温度が當温の場合は問題ないが、富温より高
くなるとセラミックスの熱膨張係数が、次の表に示すよ
うに、鋼と比べ極端に低いために嵌合面が分離してしま
うという問題が生ずる。However, ceramic parts reinforced by the shrink fit method have no problems when the operating temperature is at a low temperature, but when the temperature is higher than a high temperature, the coefficient of thermal expansion of ceramics changes compared to that of steel, as shown in the following table. Because the height is extremely low, a problem arises in that the mating surfaces separate.
例えば、窒化硅素系セラミックスの棒又はパイプを鋼に
焼ばめ固定する場合、使用温度を仮りに２００℃とした
場合、使用温度では、
セラミックスの径Ｘ （１，３−０，３） Ｘｌ０−’
Ｘ２００のずき間がセラミックス材と鋼補強材との嵌合
面に生じることになる。この値を焼ばめ率に換算すると
２．０／１０００になり、焼ばめ時においては固定に必
要な力を付与する焼ばめ率以外に、前記の２．０／＋０
００を加えた非常に高い焼ばめ率によって焼ばめる必要
が生じてくる。For example, when shrink-fitting a silicon nitride ceramic rod or pipe to steel and assuming that the operating temperature is 200°C, the diameter of the ceramic at the operating temperature is X (1,3-0,3) Xl0- '
A gap of X200 will be created on the mating surfaces of the ceramic material and the steel reinforcement. Converting this value to a shrink fit rate is 2.0/1000, and during shrink fit, in addition to the shrink fit rate that applies the force necessary for fixing, the above 2.0/+0
A very high shrink fit ratio of 0.000000000 creates the need for shrink fitting.
これに、焼ばめ作業に必要な余裕間隙を考えると、実際
作業に当たっての焼ばめ温度４才４００〜５００℃とい
った非常に高い温度が必要となり、焼ばめ作業自体が困
難になる他に、焼ばめ時に熱応力でセラミックスに割れ
が生ずるおそれもある。In addition, considering the clearance required for shrink-fitting, a very high temperature of 400 to 500°C is required for shrink-fitting in actual work, which not only makes the shrink-fitting work itself difficult. There is also a risk that cracks may occur in the ceramic due to thermal stress during shrink fitting.
これらの問題を解消する方法として、前記の鋳ぐるみ法

た鋳くるんだ外層材の固定力（残留応力）の正確な把握
が困難である等の問題がある。As a method for solving these problems, there is the above-mentioned casting method. This casting method involves casting molten steel around a ceramic member to fix the ceramic.
There are problems such as the method of fixing the ceramic member to the mold is difficult, and it is difficult to accurately grasp the fixing force (residual stress) of the outer layer material wrapped in the casting.

いで、全体を外筒鋼の焼もどし温度、一般には５００〜
６５０℃に均熱して外筒鋼のマルテンサイトを分解させ
た後、冷却する。[Means for Solving the Problems] The present invention solves the above problems by using martensitic steel as hardened as the outer cylindrical steel into which ceramics are fitted. Specifically, the ceramics are shrink-fitted at a temperature below the tempering temperature at which large shrinkage does not occur due to decomposition of martensite, generally at a temperature below 150°C. Next, the entire body is heated to the tempering temperature of the outer cylinder steel, generally 500~
After soaking at 650°C to decompose martensite in the outer cylinder steel, it is cooled.

へ変態し、この変態による収縮で夕）筒鋼が内装された
セラミックスを締め付ジノ固定するものである。During this soaking process, the martensite in the outer cylinder steel transforms into ferrite, and the shrinkage caused by this transformation causes the ceramics with the inner cylinder steel to be tightened and fixed.

A cylinder with a length of 5 Qmm was cut out and water quenched at 850°C. The inner surface of this cylinder has an outer diameter of 4
The outer cylinder was polished to match the outer diameter of a sialon sintered body with a diameter of 0 mm, an inner diameter of 20 mφ, and a length of 50 mm, and then heated at 150°C.
Shrink fit. The figure shows a cross-sectional view of a structure in which a ceramic cylinder (2) is shrink-fitted to a steel outer cylinder (1). The relationship between the inner diameter of the outer cylinder, the outer diameter of the ceramic, and the shrink fit ratio at the time of shrink fit is shown below.

/ mm2. This value is 2.7/1000
This corresponds to the stress when shrink-fitting with a shrink-fit ratio of . Therefore, even if the outer cylinder is heated to 200℃, it will still be 0.7/1000.
A shrinkage fit ratio of (-2.7/1000 - 2/1000) remained, and there was sufficient force to fix the ceramics at this temperature.
