After many inspections and consultations, Baoji Huiyou Metal Materials Co., Ltd. appointed our company (Beijing Dongbiao Electronics Co., Ltd.) to manufacture a 55KW for Baoji Huiyou Metal Materials Co., Ltd. after comprehensive evaluation of technology, quality, and qualifications. And a 45KW frequency converter in accordance with the titanium plate mill process. This set of titanium plate mill work roller diameter 45mm, transmission control motor 45KW; work roller diameter 90mm, transmission control motor 55KW.
The scope of supply includes one roller shifter for a 55 KW titanium plate mill and one for a 45 kW titanium plate mill. The two inverters are our high-performance vector inverters. This series of inverters is a high-precision, rapid adjustment capability, high degree of smoothness, mergers and mainstream industrial communication functions, can achieve stable, flexible and reliable basic automation level control. In terms of service, our company visited many companies and discussed with many titanium plate rolling companies on their technologies, processes, and production experience. Many improvements were concluded and applied to the customer's titanium plate mill AC speed control system to realize titanium and tungsten. The high-precision sheet rolling of alloys such as molybdenum and molybdenum makes the user's operation simple and convenient, easy to maintain, and brings high economic benefits to the user. The user is very satisfied with the equipment and service, and is well received by the user.
The application of our company's 55KW and 45KW frequency converters in titanium plate mill solved the unsolvable problem of DC speed regulating system in the rolling of metal materials. In China's traditional metal rolling field, the DC speed control device has always dominated, but the DC motor has a series of shortcomings, such as the commutator and brush on the structure to increase the daily maintenance, and the brush and commutator often produce sparks. The installation environment is better and can not be used in flammable and explosive places, the volume and weight of the AC motor with the same capacity and the moment of inertia are larger, the price is higher, and the efficiency is 2 to 3% lower than the AC motor. However, our company's high-performance frequency inverter drives the AC motor to achieve rolling transmission, completely overcoming the shortcomings of the DC speed control system. Our company's East Standard high-performance vector inverter is a full range of inverter from 380V-1140V voltage level and 11KW-2500KW power level, with less maintenance, powerful functions, wide speed range, fast dynamic response, and good static difference. High precision, control mode is full vector control, flexible control, strong overload capacity, strong versatility, etc. It can meet the application of various types of precision grade, power range, AC rolling mill drive, our company is willing to know with the metal rolling industry The people work together to make frequency conversion speed control widely used in the field of metal rolling.
