　　2, electric drive

　　1) Blast furnace main pumping start plan

　　The main exhaust fan of the blast furnace in the steel industry, especially the new blast furnace, is equipped with high-voltage motors with high power. In order to reduce grid investment, a small starting current is required; at the same time, due to the particularity of the process, the reliability is very high. In response to this demand, we recommend to our customers to use our company's electromagnetic voltage regulation and compensation soft start series products (link), which have the power grid current during starting, small grid voltage drop, high reliability, stable starting process, and good starting repeatability. It is very suitable for the soft start of high-power and super-power high-voltage motors. The typical one-time solution diagram is as follows, users can choose according to different needs:

　　This scheme is also suitable for the start of high-power and high-voltage motors in oxygen production, sintering and other processes;

　　For customers with limited budgets and better power grid conditions, you can also choose soft start products for water resistance voltage regulation compensation (link), or customers with smaller power motors and good power grid conditions can use traditional soft start products: electromagnetic voltage regulation Soft starter, high-voltage solid-state soft starter, water resistance soft starter, etc.

　　2) Sintering main pumping start plan

　　The sintering main exhaust fan generally has a large starting resistance distance, and the motor is required to output a higher torque when starting. Therefore, the starting current is large and the starting time is long. In order to ensure the best starting effect, it is necessary to control the motor current within the limited value so that the voltage drop of the power grid is not too large, and to control the starting time to a minimum. Set value to reduce the time of climbing and descent. In response to the needs of this working condition, we use our company’s proprietary intelligent starting mode on electromagnetic voltage regulation and high-voltage solid-state equipment. Through software artificial intelligence prediction, the current climbing and falling time are minimized to make the motor Complete the entire starting process on the set current value to achieve the best starting efficiency and minimum starting time. For customers with small power grids, we recommend the use of electromagnetic voltage regulation compensation soft start equipment, which can better control the voltage drop of the power grid when the motor starts, reduce the starting time, reduce the mechanical impact of the load, reduce the motor heat, and protect the motor and load.

　　3) Belt conveyor starting scheme for coal injection, continuous casting and other processes

　　Belt conveyors usually require frequent start and stop, and traditional hydraulic resistance soft start equipment cannot meet the requirements. For this type of load, we use electromagnetic voltage regulation or high-pressure solid-state soft start equipment to complete its start. These two types of products have a single start temperature rise of 1-3 ℃, which can meet the requirements of multiple frequent starts, especially suitable for frequent needs such as belt conveyors. Starting equipment.

　　5) Energy-saving control and starting solutions for various low-voltage motors

　　For all kinds of low-voltage motors, we provide two driving modes: inverter and low-voltage solid-state soft start.

　　For fans, water pumps and other types of loads with low operating efficiency, we recommend using low-voltage inverters for driving, which can achieve the soft start function well, and at the same time, through frequency conversion operation, energy saving and consumption reduction;

　　For equipment with higher operating efficiency, or when an economical soft start solution is needed, we provide low-voltage solid-state soft start products to reliably complete the motor starting process at the lowest cost, reduce grid voltage drop and load impact, and protect the equipment.
