Specification

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.
