On March 1st, the world's first stainless steel double-flow continuous casting machine with a maximum section of 230×1600mm² designed, manufactured, installed and debugged by China Heavy Duty Institute for Fujian Qingtuo New Materials Co., Ltd. (hereinafter referred to as Qingtuo New Materials) was equipped with a hot test of one hot test!
In the field of stainless steel production, Qingtuo New Material has the world's largest single steel output. During the hot test, the continuous casting machine runs stably, has good process parameters and excellent casting billet quality. At present, the casting machine has been officially put into production, which fully demonstrates the leading position of the "intelligent continuous casting" technical team of China Heavy Duty Institute in the domestic stainless steel continuous casting profession.
The continuous casting machine integrates the most cutting-edge continuous casting technology and equipment in the field of stainless steel, mainly including a new roller structure developed for stainless steel characteristics, a dynamic secondary cold water model with integrated optimization, the latest developed vibration theory and its control model, an automatic slag adjustment line model that prolongs the life of the immersion nozzle, an electric cylinder liquid level detection technology and automatic pouring model with a liquid level accuracy of up to 2mm, a casting billet precision scale model and a cutting optimization model.
In addition, the casting machine is also equipped with roller-magnetic electromagnetic stirring, automatic slagging robot, automatic number spraying robot, new deburring machine rotating up and down, casting grinding equipment and other equipment technology to improve the yield of stainless steel products.
Over the years, the continuous casting team of China Heavy Duty Institute has adhered to technological innovation and science and technology to lead high-quality development, closely cooperated, interconnected and interacted with Tsingshan Group, complemented each other's advantages, realized value co-creation and sharing, and injected strong scientific and technological momentum into the construction and strengthening of the industrial ecosystem of Tsingshan Group, the world's largest stainless steel enterprise, and promoting the high-quality development of the stainless steel industry.
