Series of energy-saving Soderberg
0050.0001 chloride is not more than 0.00020.0002 carbon disulfide in the enterprise is not greater than 0.000050.00006 FOCT17746-79 production of titanium sponge in full compliance with domestic and international user requirements. Rrate & Whitney. Boeing, GeneralElectric, Rollsroyse company is to the production of titanium sponge applied to the aerospace industry. Companies are sealed in vacuum equipment and devices to improve, in order to avoid saturation of gas impurities in titanium sponge to reduce the possibility of contamination by impurities. Enterprises proposed a titanium melting shop, the installation of a titanium sponge cutting machine, submerged arc furnace control system reform, reform is equipped with a gas mixture of steam condensate system,[link widoczny dla zalogowanych], chlorination equipment,[link widoczny dla zalogowanych], improved production of hybrid titanium furnace, submerged arc furnace gas fine cleaning system to improve . In addition to business use of titanium tetrachloride fine lutetium vanadium a chemical refining process, using waste lime for disinfection of calcium chloride plant to improve the quality of the anode chlorine Court information and reduce the production cost of titanium sponge. Protect the surrounding environment is the most important aspects of business activities is one. Enterprise into a central laboratory, the implementation of effective pollution control and natural objects. To ensure that harmful substances into the atmosphere of the standard,[link widoczny dla zalogowanych], companies use the 70 kinds of dust collection equipment and net gas facilities. Chlorine and hydrogen chloride emissions, local sources of dust emissions are consistent with the limit allowable concentration standards. Gas fine cleaning system using submerged arc furnace dust. Purification of gas and dust mixture of 99% to 100%. Process dust precipitator device rate of 70% to 80%. With the production of sewage purification facilities, use of rainwater as process water, the use of water recycling rate of 80.2%. Lime production waste, the production of titanium and vanadium scrap copper are fully utilized, reducing the formation of solid waste. 1998 enterprises to adopt the introduction of wastewater purification technology to produce the flocculant, to avoid building costly settlement pool, and to ensure full sterilization of solid residues.

(Editor He Yunping) series Soderberg saving very little rain since the fall of 2002, 2002 Winter / 2003, Norsk Hydro power generation has dropped significantly. Many were forced to the output of aluminum. North Kish Rohe series of current company Karmoy aluminum fell from 135kA 120kA, for up to four months. in order to save energy, electrolyte composition but also to adjust the direction of less excess aluminum fluoride, but also a greater decline in cell voltage. When the cell transferred to the new thermal equilibrium when they made a number of issues. electrolyzer made in respect of the cathode reaction is the fastest damage / leakage The number and the hot cathode shield points down to zero. crust thickening tank to help, especially in the upper part. overheated reduced, resulting in point-cutting took place stacking. anode effect frequency also be affected. As compared with the electrolyte small excess of aluminum fluoride, the temperature rise from the 960 ~ 965 �� to 970 �� or higher. also observed dust and fluoride emissions. because the acidic electrolyte cell in the lower stability of operation, the production of aluminum in sodium content increased by 30%. Norway Xi Deluo aluminum company in response to these issues and gain experience in different measures. In this power-saving period,[link widoczny dla zalogowanych], they observed both positive and negative role. on a more detailed report, see Proceedings of 2004 Annual Meeting TMs. (Lu fire)
