コストアップが問題であった。Ordinary cast iron rotors are made of cast iron with an FC of 20 to 25, and have excellent friction performance, but are somewhat inferior in strength and noise reduction effect. The damp rotor is made of cast iron with an FC of 10 to 15, and although it has an excellent noise reduction effect, its strength is extremely low. In addition, the cast-in steel plate rotor is made by integrally casting a steel plate on one side of the annular rotating part of the disc rotor to ensure the accuracy of the mounting surface and to improve the strength. However, the problem was that the cost increased due to the additional steps.

Furthermore, the present invention provides a method of manufacturing a disk rotor that achieves improved strength of the mounting portion.

In a method for manufacturing a disk rotor in which a mounting portion is integrally formed, ferrotitanium and/or metal titanium is provided at the interface between the lower mold and the upper mold, and C3.7 to 4.2 wt%, 3i2.3
A molten metal containing ~3.0wt% and the remainder "e" and unavoidable impurities is supplied to the lower mold to fill it, and then flowed into the upper mold while melting ferrotitanium and/or metallic titanium to form the attachment part. The Ti content in the cast iron material is 0.05 to 0.

整すべきである。[Function] The sliding parts of the disc and rotor are made of high carbon (3,7~4.
2 wt%) and high silicon (2.3-3.0 wt%)
The structure is such that a large amount of free graphite, which is grown by manufacturing it with cast iron, is present to increase the damping ability and provide a noise reduction effect. Furthermore, the strength of the mounting part is increased by making the graphite finer by adding 0.05 to 0.3 wt% titanium to such cast iron. In addition, an in-mold method can be used to manufacture the sliding portion and the mounting portion from different materials in a single casting process. In other words, this method aims to impart locally different properties to a part of the casting by roughly alloying it with other metal elements. Use something to hold the lumps, etc. Therefore, when casting disc rotors, the sliding part is used as the lower mold, and the mounting part is assembled so that it is cast integrally with the sliding part, and the interface between the two is made of ferrotitanium or metallic titanium in the form of a plate of sponge titanium. Arrange things etc. With this structure, the lower mold is first supplied with molten metal, and after filling it, the molten metal contacts the ferrotitanium and sponge titanium, reacts with the titanium, dissolves them, and flows into the upper mold. Due to solidification, the attachment part formed by the upper mold becomes a casting containing titanium, and has a structure in which free graphite is extremely finely divided. The amount of ferrotitanium and metallic titanium is determined by the amount of Ti at the mounting part.
The content should be adjusted so that it is (1.05 to 0.3 wt%).
