1) Tinplate & TFS Productionin ERDEMIR:

Cold rolled low carbon mild steel can be electrolytically

coated either by tin in various coating weights or

chromium. Products can be supplied in coil or sheet in the

thickness of 0.10-0.60 mm.

Production methods of Tinplate and TFS in ERDEMIR:

Electrolytically tin or chrome coated low carbon steel

Batch or continuous annealed Single or double reduced

Coil or cut into length as a sheet

ERDEMIR tinplate is produced in two main types;

Single Reduced (SR) and Double Reduced (DR).

ERDEMR tin free steel is mainly single reduced.Single Reduced (SR): Steel strip is reduced to desired

thickness in one step by cold rolling in the cold mill and

subsequently annealed, tempered then coated (depending

on the steel quality & annealing type). SR Tinplate is

mainly used in, 2 and 3 - pieces can bodies and bases,

industrial can bodies and bases, beverage cans, easy-

open lids and crown caps, aerosol bodies, bases and tops.

Double Reduced (DR):Steel strip received a further coldrolling in which the steel is reduced by 10 to 30 percent

after annealing. Thus the steel reaches its final thickness

in two separate cold rollings (depending on the steel

quality & annealing type). DR Tinplate is mainly used in

2 - and - 3 pieces can bodies and bases, industrial can

ends, easy-open lids, twist-off caps and aerosol bodies.

: ,

Annealing:The steel is heated in a reducing atmosphere justabove the recrystallization point and then cooled.There are two types of annealing: batch annealing(BA) and continuous annealing (CA).

Tempering:The strip is temperedof hardness, surface smoothness and the a secondary rolling thDR tinplate can be do

Temper Mill No. 2(DR)

Temper Mill No. 1

Pickling:The steel is pickled to eliminate the iron oxidethat forms on the strip during hot rolling process.

Tandem Rolling:In this process the thickness of strip is reduced withoutmodifying the width.

Cleaning:After cold rolling, the steel is covered with a thin film ofoil that is removed by an alkaline cleaning operation inorder to optimize the annealing process.

Precautions for Tinplate

Since tin coating is relatively soft in order to avoid scratches, necessary measures should be taken during transportation

and handling.

Paintability, solderability, paint adhesion and mechanical properties detoriorate as time passes.

Although tinplate has an excellent corrosion resistance, it becomes rusty in moist atmospheres. It should be processed

as soon as protective packaging is removed.

Tin is soluble in powerful alkali solutions so tinplate must be painted or lacquered when it is used for alkali solutions.

Tinplate becomes darker in case of contact with sulphur contents. So it should be painted or lacquered in these kind of

applications.

Precautions for TFS TFS is not compatible for soldering, welding and DWI drawing operations.

Metallic coating layer of TFS has high electrical resistance, before welding, this layer should be removed.

TFS has a tendency to rust in humid atmospheres. It should be processed as soon as protective packaging is removed.

If it is to be used in connection with food and beverage, its surface should be painted and lacquered.

Scratches which may appear on surface due to incorrect transportation and handling should be avoided.
