Recently, in the Sangang bar production line, after the robot "eyes" flashed and flashed, the mechanical arm sucked up the grinding wheel saw blade and accurately loaded into the drive spindle. The error was only 0.02 mm, which was thinner than the hairline, and the saw blade was automatically online. Replace it for 8 minutes. Since May of this year, this set of automatic grinding wheel sawing online replacement system has been successfully installed and debugged by Sangang Group, filling the blank of automatic replacement of medium and large-sized grinding wheel saw blades, and it is the world's first in the metallurgical equipment industry. Experts from the United States, Germany, Austria and other countries have come to inspect and have raised their thumbs.
This system has already declared 10 national patents, and can increase the benefits of enterprises by more than 5 million yuan a year.
The purpose of the grinding wheel saw blade is to cut the finished bar according to the order requirements. The single saw blade weighs 50 kilograms and has a diameter of 1.25 meters. The production line needs to be replaced every hour, with fast wear and high frequency of use. In the past, this huge saw blade required two workers to work together in a small working space. Each replacement took more than 30 minutes, and the production line had to wait for work.
Faced with problems such as low efficiency, high labor costs, and high security risks, how to break through?
In 2018, Sansteel Group and Sanming College rely on the Shuguang College jointly established by the two parties to develop an automatic online replacement system for grinding wheel saw blades through school-enterprise cooperation. At that time, this technology was still blank in the world, and there is no reference to it. The research team organized mechanical, electrical, automation, equipment materials and other multi-disciplinary and multi-work types to cooperate with each other. It took more than one year to develop successfully.
The success of this "world's first" is a microcosm of Sangang's intelligent manufacturing. In recent years, intelligent manufacturing has become a powerful engine to promote the quality and efficiency upgrade of Sangang Group.
The slab robot automatically adds slag, and the converter robot automatically measures the temperature. The robot replaces the workers to take up the heavy and dangerous work in the production line, and is gradually realized in some positions.
Today, this 61-year-old steel company has grown along with the construction of New China and has become the first national AAA-level steel industry tourist area in Fujian Province. With an annual output of 11 million tons of steel, it is the largest steel company in Fujian Province. . Since 2016, Sansteel Group has been stepping up its efforts in promoting the integrated development of “production, learning and research”, and has invested a total of 3.2 billion yuan in research and development for scientific and technological innovation and technological transformation. Through the construction of information technology to promote the deep integration of the Internet, big data, artificial intelligence and the real economy, enterprises are moving towards the direction of smart manufacturing of steel.
