1. FEEDING AND SUPPLY STATION

The assembly is perpendicular to the longitudinal axis of the skin pass. It's made of:

a) TWO FEEDING STATIONS:

Mechanically welded frames on which wooden skids are fixed for protection.

Recovered stations.

b) AN UNWINDING STATION:

Mechanically welded frame supporting motorized steel rollers of dia. 280 mm.

Its purpose: to ensure the manual stripping and the introduction into the preparation station of the start of the coil, non-compliant in thickness.

c) A DROP STATION: recovered material

Made of :

- 1 engagement spade

- 1 set of trainer rollers

- 1 hydraulic shear capable of a max. thickness of 5 mm Material entirely recovered, in good condition

d) All of the above positions are served by an UNDERGROUND HYDRAULIC MOTOR AUTO TRUCK comprising:

- 1 group for elevation: parallelogram system - stroke 750 mm

- 1 translation - stroke 11 m: hydraulic system or electric motorization but 2 speeds

New equipment defined by specifications

2. SKIN PASS MILL

a) AN UNWINDER:

Chuck diameter 610 mm, suitable with a nose

Chuck, reducer, brake, motor assembly, mounted on a single frame with positioning pallet

Strip running speed: 300 m/min, Power: 400 kW

Set recovered and adapted for the new speed and the weight of 30 T

b) A CHUCK NOSE:

Mechanically welded, retractable

Able to support the additional weight and leaving free the passage of a coil with an external diameter of 1,900 mm

The assembly is fully hydraulic new equipment

e) S-ROLL:

Mechanically welded, ensuring the drive of the belt head towards the S-block Material fully recovered

d) ACCESSORIES:

A bracket is provided to collect butts and distribute them in a skip provided for this purpose (adapted bracket)

e) A RECOVERED ENTRY SET:

Including a fixed table on which is articulated a scissor facilitating the introduction.

It is modified to allow the maximum coil dia. 1,900 mm

f) AN S-BLOCK:

Used in motorized restraint - overall installed power: 350 KW It is composed of:

- 2 main rollers diameter 700 mm in steel

- 2 coated rollers diameter 250 mm motorized by hydraulic motors and reducer

- mobile deflectors fitted with bearings allowing the introduction of the strip up to the dia. 500 mm deflector roller
