Jiangsu Yonggang Group Co., Ltd. is located in Zhangjiagang City, Jiangsu Province, founded in 1984. covering an area of 3500 mu. After more than 20 years of construction, the enterprise has developed into a large-scale combined steel enterprise integrating mining, ironmaking, steelmaking and steel rolling. Jiangsu Yonggang Group Co., Ltd. has an annual steel-making and rolling capacity of 5 million tons, a total asset of 14.5 billion yuan, a sales revenue of 24.657 billion yuan and a profit and tax of 2.228 billion yuan in 2007. ranking No. 192 of the top 500 enterprises in China and No. 97 of the top 500 manufacturing enterprises in China. The products of the company have been used in the key projects of Shanghai Oriental Pearl TV Tower, Zhejiang Qinshan nuclear power station and Jiangyin Yangtze River bridge, and exported to more than 30 countries and regions such as the United States, Italy, Japan and so on.

　　The flow measurement of circulating cooling water in the mold of continuous casting machine is the key link of continuous casting process. The return water of each section of the caster mold is the key to ensure the temperature of the mold to be maintained. Therefore, once the return water flow is abnormal, the correct judgment must be made in a very short period of time, and the interlocking continuous casting equipment shall be shut down, otherwise the serious consequences of the mold explosion of the caster will occur.

　　It seems to be a simple measurement of common circulating water, but the measurement environment is very bad. There are a lot of large-scale interference equipment on the site of continuous casting machine, such as electromagnetic brake, electromagnetic mixer and so on. This makes the electromagnetic flowmeter in the measurement of the field circulating water flow will be interfered, resulting in abnormal current output. However, once there is an abnormal output, the system will give an alarm, send out an interlock stop command, and eventually lead to stop affecting production, causing major economic losses and even safety accidents.

　　According to authoritative analysis, only a few manufacturers at home and abroad can stably apply electromagnetic flowmeter to the mold of continuous casting machine in steel plant. Even the international first-line brands will be abnormal to varying degrees. Therefore, the measurement of cooling water flow in the mold can be called the application difficulty coefficient of electromagnetic flowmeter at present.

　　The R & D team of sinir deeply analyzed the field interference environment, and simulated the field interference source as much as possible. After nearly a year's research, the special electromagnetic flowmeter for caster mold was launched. The flowmeter has been optimized in hardware and software, and upgraded in program. CPU, current output module and display communication module are used in hardware Independent isolation technology, software to increase the interference signal multiple validation technology, and ultimately make this flowmeter successful and stable operation. This flowmeter has a great advantage in measuring the stability of continuous casting mold, but the price is lower than that of traditional international brands, so it is highly recognized by users. In addition, a large number of orders have been obtained in the continuous casting mould of major steel plants in China.
