Application

1. Frequency converter is used in rolling mill load

In the metallurgical industry, AC-AC frequency converter used to be used in large rolling mills in the past. In recent years, AC-DC-AC frequency converter has been adopted. Ac frequency converter has become a trend of rolling mills, especially in light load rolling mills.

2. Frequency converter is used in hoisting load

Winch load adopts frequency conversion speed regulation, stable and reliable. Blast furnace coiling equipment is the main iron - making raw material conveying equipment. It requires smooth starting and braking, acceleration and deceleration uniform, high reliability. The original use of cascade, DC or rotor series resistance speed regulation mode, low efficiency, poor reliability. The ideal effect can be obtained by replacing the above speed regulation mode with AC frequency converter.

3. Frequency converter is used in converter load

Converter load, using AC frequency conversion instead of DC unit is simple and reliable, stable operation.

4. Frequency converter is used in roller table load

The roller table load, mostly in iron and steel metallurgy industry, adopts AC motor frequency conversion control, which can improve the reliability and stability of equipment.

5. Frequency converter is used in pump load

Pump load, large volume and wide range, including water pump, oil pump, chemical pump, mud pump, sand pump, etc., there are low pressure and small capacity pumps, there are high pressure and large capacity pumps.

Many water pump, chemical and fertilizer industry of chemical pump, reciprocating pump, non-ferrous metal and other industries of mud pump using frequency control, all produce very good results.
