In its program, Production and Engineering Company ENCE GmbH highlights the most significant metallurgical equipment; this equipment complies with the highest international quality standards and may be offered to customers at competitive prices.
Engineering company ENCE GmbH offers different units, packages and associated rolling mill equipment, steel strip pickling lines, steel coils hot dip galvanizing lines, strip polymer coating lines and sheet bending machines. As an example company ENCE GmbH offers a solution for blowing off the emulsion from the skin rolling mill developed according to the Customer’s technical assignment.
If the mill speed of the existing rolling mill is limited due to the amount of emulsion at the exit of the rolling mill, the use of a strip blow off system to blow off the emulsion from the skin rolling mill is required. The
The excessive amount of the emulsion at the exit of the rolling mill reduces the productivity as well as the rolled product quality. The rest emulsion
The aim of the strip blow off system from the skin rolling mill is to prevent the strip from the penetration of the excessive emulsion, what is more efficient then to remove the excessive emulsion on the strip.
The strip blow off system from the skin rolling mill will keep the strip clean and dry thanks to the following:

Technical data
Location: upper and lower back up rolls
Quantity: two sets, i.e. rolling mill manifolds (upper and lower for each device), four cleaning devices in total.
The load is created with the help of the balancing counterweight system.
The backup roll cleaning devices provide the efficient method of removing the rests of the emulsion from the surface of the upper and lower backup rolls.
The cleaning blades will be located in a special detachable cartridge and can be installed and adjusted during the roll change,
Technical data
Location:
Quantity: two supporting guards for each rolling mill manifold.
Six guards in total.
Operation principle: excessive emulsion absorption by the material mounted on the inner surfaces of the upper roll chock.
The roll chocks guards are designed to reduce the emulsion flow and splashing along the roll full length as well as around the roll neck.
Such guards are mounted on the inner surfaces of the roll chocks and can be easily removed together with the chock during the roll change.

Air nozzles
The air blower nozzles are mounted centrally and directed to the backup and
The nozzles system is mounted midmost the rolls and is directed to the roll edges, thus providing more efficient removing of excessive emulsion by blowing off every zone of the roll surface.
Other air nozzles are directed to the
The nozzles are mounted specially to blow off the roll surface. This allows the air nozzles to remove any amount of the excessive emulsion which is taken off to the strip edges and then efficiently removed to the roll edges from the strip center.
The
Drain pan for rolling emulsion
The nozzles are mounted on the steel frame with integrated emulsion splash guard. The supporting frame is mounted on the side guides inside the mill stand. The frame can be removed by the hydraulic cylinder to provide enough space for roll change and access for cleaning the drain pan.
The frame, lower and upper emulsion splash guards and nozzles have a rigid construction which prevents the damages due to strip breakage and coil (strip) end
The lower part of the new drain pan is designed to prevent the dew point and will be declined from the strip center, so that the emulsion vapors condensation moves naturally to the pan sides which are beyond the maximum strip width. The drain channel is designed to catch the drops formed on the back side of the pan due to condensation and to drain the emulsion to the pan edges, which are beyond the maximum strip width.
The system air is supplied by the pipeline and flexible hoses.
The control devices are provided for the whole new equipment with pneumatic functions. The control devices for air flow control are provided for.
The hydraulic control devices are provided for the new
The devices mounted in the system (for example proximity switches, etc.).
The painting will be performed according to the standard painting specification which fully complies with the standard international requirements.
