Sweden-based Uddeholm AB Hagfors, manufacturer of tool steel for industrial tools, has recently commissioned phase one of the modernization of the EAF fume treatment plant with latest filter technology from SMS group. As phase one of the project, SMS group upgraded the roof canopy installing a high-efficiency EAF fume evacuation hood â the patented SMS Frustum â, replaced the existing secondary duct system, installed a highly efficient axial cyclone and a new pulse jet filter.
The newly developed high-performance equipment from SMS group ensures a higher suction capacity of 800,000 cubic meters per hour with a ten filter compartment. The two fans with 710 kW variable speed motors reduce energy consumption thanks to the âTotal Pressure 11â? concept (280 mmWG). The new filter technology from SMS group thus helps Uddeholm to achieve better evacuation of the exhaust gases during the melting process in the electric arc furnace, while minimizing energy consumption.
With the substitution of the primary fume line, the second phase, planned for August 2017, will complete the EAF fume treatment plant modernization. The SMS group is a group of companies internationally active in plant construction and mechanical engineering for the steel and nonferrous metals industry.
