Minimills for Long Products<br />
Combi-caster casts several formats at the same time<br />
Siam Yamato, Thailand: Minimill for<br />
medium steel sections in operation<br />
Commissioning of five-strand combi-caster for<br />
seven different billet/bloom formats and beam blanks.<br />
In October/November 2009, Siam Yamato Steel Company (SYS) started production<br />
of medium steel sections at its new minimill in Rayong, Thailand. First, the mediumsection<br />
rolling mill supplied by <strong>SMS</strong> <strong>Meer</strong> was commissioned, followed by the meltshop<br />
and the five-strand combi-caster supplied by <strong>SMS</strong> Concast. The first heat was<br />
cast on all five strands with a common casting size of 200 mm x 230 mm. After that<br />
also blooms of 230 mm x 450 mm casting size were successfully produced on the<br />
new combi-caster.<br />
Steelworks for 700,000 tpy. The steelworks<br />
and rolling mill have been designed<br />
in such a way that the billets and blooms<br />
produced in the steelworks can be directly<br />
hot-charged into the rolling mill. The new<br />
steelworks has a production capacity of<br />
700,000 tpy. It features an 80-t electric arc<br />
furnace, a ladle furnace and a combination<br />
caster.<br />
Low energy consuming EAF. The electric<br />
arc furnace is equipped with the latest<br />
generation of Conso oxygen technology.<br />
This technology reduces electrical energy<br />
consumption while enhancing the productivity<br />
of the furnace. The dedusting<br />
system for the meltshop conforms with<br />
the high applicable clean-air standards.<br />
Seven billet/bloom formats plus beam<br />
blanks. The combi-caster is a new development<br />
by <strong>SMS</strong> Concast. This is the first casting<br />
machine enabling different billet and<br />
bloom formats to be cast at the same time.<br />
A total of seven different billet/bloom formats<br />
can be cast, ranging from 130 mm x<br />
130 mm to 230 mm x 450 mm. If required,<br />
the plant can even be converted to beam<br />
blank production.<br />
Medium section mill for 400,000 tpy. The<br />
semi-continuous medium section mill supplied<br />
by <strong>SMS</strong> <strong>Meer</strong>, for an annual production<br />
of 400,000 t of final products, is intended to<br />
produce steel sections from 100 mm x 50<br />
mm to 350 mm x 175 mm as well as channels<br />
and angles. Adding rounds and flats to<br />
the product range at a later stage is possible<br />
within the framework of a future expansion<br />
project. The mill features a 130-t/h walkingbeam<br />
furnace, a two-high reversing roughing<br />
stand as well as a continuous finishing<br />
train made up of nine roll stands, six of<br />
which being universal/two-high stands. The<br />
roll stands are modular compact stands in<br />
CS design. They are interchangeable and<br />
can be used alternatively as horizontal/vertical<br />
or universal stands.<br />
Overall planning. The overall planning of<br />
the works was realized jointly by <strong>SMS</strong> Concast<br />
and <strong>SMS</strong> <strong>Meer</strong>. The successful commissioning<br />
of the meltshop and the rolling mill<br />
is a demonstration of the <strong>SMS</strong> group’s competence<br />
and innovative power in the longproducts<br />
sector.
