Company Profile

Dalian Huarui Heavy IndustryGroup Co,Ltd.(hereinafter called"DHHI") is a subsidiary company of Dalian Heavy Industry Equipment Group Co. Ltd. It is the large, key and leading enterprise in heavy machinery industry and the key enterprise for manufacture of new energy equipment in China.At present. DHHI has about 10000 employees, of which 1800 persons are engineers and technicians,total assets over CNY 20 billion yuan. DHHl established *1 headquarters and 5 research and development bases" which cover an area of over 2 million square meters.DHHI has two wharves with a capacity of 5000dwt each and about 3600 sets of various processing equipment with a capacty for producing and processing about 300.000 tons of heavy machinery products per year.
DHHI mainly serves the basic fields of national economy such as metallurgy.port, energy,mining, engineering.traffic.logistics.shipbuilding. etc., and supplies heavy and large equipment complex, product and service with high and new technical content. it has four major traditional and leading products. i.e. bulk material handling machinery. metallurgical machinery.hoisting machinery. port machinery and five major growth-type product le core components of wind turbine, large ship crankshaft, tunnel boring machine/slurry shield machine. trong equipment for nuclear power station.high-end casting and forging.
DHHI is the main enterprise in designing and manufacturing large submerged arc furnace in China. The products mainly include calcium carbide fumace, ferroalloy furnace. silicon metal furnace, titanium slag furnace. etc. Since 1959 when the first submerged are inucludeecaiss produced. DHH! has supplied over 600 sets of submerged arc furnaces to domestic and overseas customers. ill now, ban has develop ea s nroduced. operation the 6.3MVA-60MVA series submerged arc furnaces and meanwhile possessed complete technology for 60MVA,75MVA,81MVA and195MVA series large size furnace,raw material treatment technology. automatic tapping
technology.Intelligent plant, etc.through independent research and development and been the standard establishment unit for submerged arc furnace industry.
 

DHHI unceasingly introduced advanced technology from abroad. lt has ever successively introduced technologies for 25MVA ferrosilicon furnace with bellow-type electrode column and for 25.5MVA silicon metal furace,technology for 25.5MVA closed-type calcium carbide furnace with combined holder type electrode column for 25.5MVA titanium slag furnace and for25.5MVA ferronickel furnace and technology for 39MVA silicon metal furnace, and made development and improvement on such basis and provided internationally first-rate equipment for the customer. DHHI unceasingly expanded the EPC projects for ore smelting furace in recent years. has up to now become the first company that obtained the qualification for EPC of smelting project in heavy machinery industry in China, and has become the earliest in the same industry and contracted the most number of EPC projects.It is capable of providing full service including overall plant design,process design and construction, equipment design. power supply and distribution design.control design.civil work design as well as instruction for manufacture, installation.commissioning.test run, etc. to the customer so as to shorten the construction period, reduce the project investment and improve the project quality efficiently.
