The invention can work in a multi-master-slave mode, and can send and receive data in a point-to-point, point-to-multipoint and global broadcasting mode; and the titanium alloy rolling mill control system based on optical fiber signal transmission is simple in structure, capable of realizing remote control, high in safety performance and system signal transmission efficiency and extremely creative.

Description

technical field [0001] The invention relates to a rolling mill control system, in particular to a titanium alloy rolling mill control system based on optical fiber signal transmission. Background technique [0002] Titanium is an important structural metal developed in the 1950s. Titanium alloys have high strength, good corrosion resistance, and high heat resistance. In the 1950s and 1960s, high-temperature titanium alloys for aero-engines and structural titanium alloys for airframes were mainly developed. A batch of corrosion-resistant titanium alloys were developed in the 1970s. Since the 1980s, corrosion-resistant titanium alloys and high-strength titanium alloys have been further developed. Titanium alloys are mainly used to make aircraft engine compressor components, followed by structural parts of rockets, missiles and high-speed aircraft. A rolling mill is the equipment that realizes the metal rolling process. Generally refers to the equipment that completes the wh...
