HOFFMAN filter (HOFFMAN) (also known as HOFFMAN filter or HOFFMAN vacuum filter) is mainly used for ferrous metals in the process of cold rolling and non-ferrous metal rolling emulsion lubrication coolant filtration process.
It is the key equipment to ensure that the process lubrication coolant reaches enough filtration precision to make the product surface quality meet the technical requirements.
Hofmann filter paper purification method:
HOFFMAN filter paper purification treatment is to take it in the work of debris, grinding wheel powder and other impurities timely removal. Common purification methods: vacuum filtration and separation.
Vacuum filtration is a vacuum filter that uses vacuum filters such as HOFFMAN, German west mark, mitsubishi Hitachi and other vacuum filters to remove the magnetic particle impurities produced by the emulsion during work.
The separation method is to apply gravity precipitation, inertial separation, magnetic separation and other devices to remove all kinds of impurities produced by emulsion at work. In actual production, several methods are used in combination. It not only makes simple, compact structure, but also has good effect, it can guarantee the high cleanliness of emulsion.
HOFFMAN Filter Paper application:
It is suitable for filtration of process lubrication coolant during cold rolling and metal hot rolling of black metal. It is mainly applied to steel cold rolled sheet, cold rolled stainless steel, steel, grinding roller mill, etc.
