CCM

Wuxi Haohua Metallurgy Machinery Co., Ltd is a comprehensive manufacturer of metallurgical machinery boasting several production bases.Established 15 years ago, the company has been supported by various first-class metallurgy machinery design institutes such as MCC Group's Beijing Research & Design Institute of Metallurgical Equipment and Wuhan Steel Designing Institute,absorbingnew and high technology from home and abroad and designing and developing metallurgy machinery with new technologies. It has proved itself as a professional metallurgy machinery manufacturer of a large production scale in a leading positionin China integrating design, technological innovation, and sales.The main products of the company includes the following: hot rolling mills for steel strip, sheet, bar, wire rod and profile steel; steel strip cold rolling mill; electric arc furnace, ladle furnace, induction furnace; continuous casting machine. Its products have been sold to most provinces and cities in china as well as many otber countries and districts in South-east Asia, Middle East, Middle Asia, West Asia, Africa and south America.----Preparation for CCM production: Check whether the electrics system, water 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 specifications. After the secondary rinsing cooling system, the billets are completely solidified straightened by the withdrawal straightening machine.The steel billet need to be cut to the set length according to the requirements required by the heating furnace, rolling machine 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 tablevia 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 transfered to the heating furnace for hot charge rolling via hot charging roller.Main components1.
