The main products of the company includes the following: continuous
casting machine, hot rolling mills for strip, steel sheet, bar,
steel wire rod and profile steel strip cold rolling mills: electric
arc furnaces, ladle furnaces, induction furnaces as well as
continuous casting machines. Its products have exported to many
other countries and districts in South east Asia, middle
East,middle Asia, East africa and south America.
Preparation for CCM production: Check whether the electrics
system,,wether supply system and oil/gas supply system can work
normally .Make sure that the ladles and tundishes are preheated
before accepting the molten steel and that the casting machine
stand ready for production.
Casting technology:Draw the dummy bar into the crystallizer from
dummy bar storage position, turn on the water cooling system,hoist
the ladle onto the ladle support to receive the molten steel, and
then transfer the ladle to the right position above tundish car.
The molten steel goes into the crystallizer via the help of the
tundish. With highly efficient cooling, steel billets with outer
shell formed move out of the crystallizer. The casting speed can be
controlled within 0-4m/min according to different billet
specifications.Through the secondary rinsing cooling system,,the
billets are completely solidified and straightened.
The steel billets need to be cut to the set length according to the
requirements required by the heating furnace,rolling mill
installation and finished product.The billets are cut to the
designed length by devices such as flame cutting machine,
synchronous hydraulic shear,etc. It is then conveyed to the billet
delivery roller table via the roller table after cutting, then
transferred to the billet cooling bed by tilting gear or lifting
device, hoisted to the appointed billet storing place after
cooling, or transferred to the heating furnace for hot charge
rolling via hot charging roller.
