Description
1.Dalian Huarui Heavy Industry Group Co., Ltd. (hereinafter called "DHHI")
Dalian Huarui Heavy Industry Group Co., Ltd. (hereinafter called "DHHI") is a subsidiary company wholly controlled by DHI▪DCW Group Co., Ltd. It is the large, key and leading backbone enterprise in heavy machinery industry in China. At present, DHHI has 8 branches and 12 subsidiaries, with about 6000 employees and total assets over 20 billion RMB. DHHI is mainly dedicated to supplying equipment complex, product and service with high and new technical content to steel, power, energy, mine, traffic and transport industries, etc. Up to now, it has had nine major products, i.e. metallurgical machinery, hoisting machinery, bulk material handling machinery, port machinery, energy machinery, drive and control systems, marine components, engineering machinery and offshore engineering machinery, etc.
DHHI established "1 headquarter and 5 research and development bases" which cover an area of over 2 million square meters. It has the capacity for independent research and development of heavy, large technical equipment and design, manufacture, installation, commissioning with mechanical, electrical and hydraulic integration as well as EPC. It is capable of international operation with products sold to 78 countries and regions. It established the national technical center (consisting of 1 design & research institute, 7 specialized design institutes, 4 research institutes and 3 laboratories), research & development center in Germany, national postdoctoral workstation, which form a perfect scientific research and development system. It was approved by the Ministry of science and Technology of China to establish the "National Technology Research Center for Drive and Center for Drive and Control of Wind Turbine" and possessed over 350 patents, 17 famous products with national, provincial and municipal level in the world.

3.Ferrosilicon production process
The qualified raw materials such as quartz, coke, iron ore pellet etc. will be delivered to the proportioning station outside the main building as per the smelting requirements. Mixed materials will be transferred to discharge conveyor, and then delivered via belt to the top of feed bins and then charged into the feed bins via triangle belt conveyor. From feed bins, the materials will enter the furnace through charging chute. Intermittent feeding method is adopted. Another charging chute is set up outside the furnace to deliver materials to second floor platform where materials are reclaimed by stoking machine and fed into furnace randomly.
The materials are fed into semi-enclosed ferrosilicon furnace. The current will be introduced into furnace via 3-phase electrode from power supply through the transformer. The electric arc produced by reaction of electrode and materials will emit heat to the smelting bath fully filled with materials. With the heat of electric arc and resistance, the materials mixed with silica, semi-coke and ironworks (steel scrap or pellet) are smelted and finally reduced to ferrosilicon. During the smelting process, the voltage grade and current intensity of the electrode are set as per smelting parameters. Since the voltage and current at different stage are not the same, the power capacity in the furnace will vary. The electrode is always inserted into the materials stably and gas is escaping evenly from the material top surface, and arc will not be exposed. Uniformly blended materials are fed into the furnace in batches when the material level drops, thus to ensure the level of material remains the same in a cone around the electrode. In order to ensure good permeability of material layers during smelting process, the high temperature gas generated from the reaction will pass through the material layers evenly and slowly to heat and reduce the materials. The material surface shall be observed periodically and treated by using stoking machine.
When the ferrosilicon produced in the furnace accumulates to certain extent, use the burner to open the tap hole so as to release the liquid ferrosilicon into the ladle. After the tapping process is over, plug the tap hole. The ladle will be transferred via rail car to the casting workshop and lifted via crane to the casting machine.
