Wuxi Haohua Metallurgy Machinery Co., Ltd owns several production basis with many sets of different kinds of mechanical machining equipment. From its establishment of 15 years ago, with the support on technology from various first class metallurgy machinery researching

and designing institutes such as MCC Group's Beijing Research & Design Institute of Metallurgical Equipment, Wuhan Steel Designing Institute,  having  been  digesting  and  absorbing  new and high technology from at home and abroad and having been designing and developing metallurgy machinery with new technology suitable for developing countries like China, has now become a professional metallurgy machinery manufacturer  of  large  production  scale  in  leading  position  in China integrating  complete   sets   of   metallurgy   machinery's   designing, technological reform, manufacturing and sales. 

The main products of this company consists hot rolling mills for steel strip, sheet, bar, wire rod and profile; steel strip cold rolling mill; electric arc furnace, ladle furnace, induction furnace; continuous casting machine, which has been sold to most of the provinces and cities in china

and far to many countries and districts in South-east Asia, Middle East, Middle Asia, West Asia, Africa and south America.

Preparation for CCM production: Check if the electric system, water supplying system and oil/gas supplying system can work normally. Make sure big steel ladle and intermediate will receive molten steel when they are hot. Make sure all the production tools and equipment are well prepared. Make sure the casting machine is ready for production.

Casting technology and process: Send the dummy bar into the crystallizer from the place of dummy bar storing position, fill the strands with  material for guiding the flow, turn on the water cooling system, hoist the big steel ladle loaded with qualified molten steel into the ladle stand, then transferred to the pre-selected position above the tundish car of the intermediate tank. The molten steel, via the intermediate ladle, is distributed into the crystallizer. With high efficiency cooling, various kinds of not completely hardened casting billet cross section is formed. The vibration device leads out the casting billet. The casting speed can be controlled within 04m/min according to different specifications. After the compulsive cooling by the casting billets secondary cooling system, the casting billet is completely is solidified. The straightener makes the arc billet straight.

The steel billet needs to be cut to length according to the requirements required by the heating furnace, rolling machine and finished product. The billet, after coming through the straightener, via the roller table, is sent to the cut-to-length device such as flame cutting machine, synchronous hydraulic shear, etc, for cutting according to the different length of cutting. 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 sent to the heating furnace for hot charge rolling via hot charging roller by billet delivery roller.
