PROCESS DESCRIPTION

1

Basically Modular Mechanical De-scaling machine is used to break the scales formed on the surface of steel rods through combined rod bending and reverse twisting on two sets of 3Nos. HCHC pulley assly.

2

Normally during cooling process of rod cooled coils, the calamine forms on the steel rod surface, which is mix up layers of 3rd oxides with different characteristics and are listed as below:

  1. Top surface Hematite (Fe2O3) – Red colour – Hardness V = 1030
  2. Middle surface Magnetite (Fe3O4) - Black colour – Hardness V = 420 to 500
  3. Inner surface Wustite (FeO) – Grey / Black colour – Hardness V = 270/350

Then inner most metal steel.

3

The quantity of each layer depends on the storing of rod coil at different temperatures and atmosphere. Generally the rods with good mechanical de-scalability, scale proportion shall be in between 0.6% to 1% of rod weight. The rod coils less than the above proportion shall be with more elastic oxides and difficult to remove by Mechanical De-scaling.

The following process classification with respect to the relative scale thickness shall be used as guideline for processing the rod coils.

  1. Mechanical De-scaling for scale thickness above 15 microns.
  2. Both Mechanical de-scaling and chemical cleaning for scale thickness 10 to 15 microns.
  3. Chemical cleaning / pickling for scale thickness less than 10microns.

PROCESS DESCRIPTION

Basically Modular Brush De-Scaling Machine is used for removal of residual scale which is left out during mechanical de-scaling from the wire rod surface. Thus, it cleans the wire rod surface and prepares the wire rod for Coating process.

4Nos. motorized, steel brush discs rotating parallely to the wire rod against the wire rod direction are used to perform this operation. The brushes are projecting from the Face of the rotating disc.

The Machine consists of 2 Modules with each two brush heads. First module is placed 45 Degree inclined to the horizontal plane, while the Second module with the same design is placed 90 degree inclined to the First Module. By this arrangement a constant and complete 360 Degree de-scaling on the wire rod is achieved. Thus, the process ensures the removal of residual scale from the surface of the wire.

PROCESS DESCRIPTION

Basically, Modular Coating machine is used for coating the De-Scaled and brushed wire rod surface with Borax. Borax acts as protective coating on the wire rod and also lubricant carrier during wire rod drawing process. It is very essential to water wash the de-scaled & brushed wire before the borax coating and dry the borax coated wire with the help of hot air before the wire enters into the wire drawing machine. Hence, a Coating machine is developed to carry out this preparation process.

Modular coating Machine performs the following functions,
1) Removes the residues and micro particles deposited on the de-scaled & brushed wire rod using hot water wash with an adequate pressure.
2) The wire rod thus washed will pass through a chamber flooded with hot Borax solution and gets coated.
3) Drying the Borax Coating: The main objective of this process is to regenerate the crystals on the surface of the wire which was dissolved in the borax solution and thus give the wire a surface texture which will act as protective coating & lubricant carrier during the wire drawing process.

ADVANTAGES

1

The optimization of Scrap’s bulk in respect to its weight, allows a substantial increase of the Scrap Value in the sale ( The Weight to bulk ratio is increased higher than 30% compared to the value of the non-compacted scrap)

2

The scrap winder –ES550 reduces rod and wire scrap into compact rolls easy to handle, store loading on to the tracks and feeding into steel mill.

3

ES 550 is Equipped with tamper free safety devices. Front extension of the machine allows the operator to stand clear from the scrap dragging in area so that he can keep a full visual and safe control of the machine during operation.

4

ES 550 is compact frame, equipped with fool proof safety devices, allow it to be used inside the factory in close proximity of the production area.

5

Designed and proven to optimize performance, reliability and simplicity during operation in a user friendly and safe environment. ES 550 makes rolls with standard dimensions and weight. A safely device avoids makes over sized rolls, and the possible problems of getting hang up during the discharging of the roll.
