Thread Content
Wuhai Zhonglian Chemical has been granted a patent for a device designed to regulate the current distribution among the conductive elements in calcium carbide furnaces. This device helps to reduce problems such as frequent damage to electrodes and overheating that occur as a result of uneven current distribution. According to information from the Intellectual Property Office, issued on August 5, 2025, Wuhai Zhonglian Chemical Co., Ltd. received a patent titled “A Device for Regulating the Current Distribution Among Conductive Elements in Calcium Carbide Furnaces”; the approval number is CN223194861U, with the application date being July 2024. The patent abstract indicates that this utility model discloses a current balance adjustment device for the conductive elements in calcium carbide furnaces. It includes a transformer, conductive elements, and electrodes; a current regulator is fitted around these conductive elements. The current regulator consists of several arc-shaped housings, with an annular bottom plate fixed to the bottom of each arc-shaped housing. At both ends of each arc-shaped housing, there are male and female clamping plates, which can be fitted together ； An annular core of the same shape is stacked on the said annular base plate; the upper end of the arc-shaped housing is fixedly connected to an annular cover plate that presses down on the annular core ； The several arc-shaped casings are connected end to end, and an annular core is formed through the coupling of male and female buckle plates. According to Tianyancha data, Wuhai Zhonglian Chemical Co., Ltd. was established in 2009 and is located in Wuhai City; it is a company that focuses on the manufacturing of chemical raw materials and chemical products. The registered capital of the company is 100 million RMB. According to the big data analysis provided by Tianyancha, Wuhai Zhonglian Chemical Co., Ltd. has made investments in 1 company, participated in 5,000 bidding projects, and holds 49 patent records. In addition, the company possesses 33 administrative licenses.
