Automatic BOX Beam Production Line with Electroslag And SAW Welding

As introduced in its product category, BOX Beam has the main application of steel structure construction of high rise building; The BOX Beam Production Line is for making this workpiece.

   1. General Introduction on BOX Beam Production Line:

   1) BOX Beam Production involves series of working process, for detail please check the 2^nd segment. Of which

    the two most critical steps are BOX Beam Assembly and BOX Beam Welding (Including consumable nozzle or

    wire electrode Electroslag welding, gas shielded CO₂ back welding, submerged arc welding);

   2) The BOX Beam Production Line designed and produced by our company was developed on the basis of 

    advanced process technology both domestic and abroad, state-of-art welding technique, and years of 

    experience accumulated;

   3) This BOX Beam Production Line has the strong points of complete configuration, high automation, high 

    efficiency, user-friendly operation. For semi-automatic BOX Beam Manufacture Line, its annual output of single shift can be above 5000Ton; For fully automatic BOX Beam Production Line, its annual output of single shift can be above 12,000Ton;

    4) The reasonable process technology and reliable BOX Beam Production machine performance makes this 

      BOX Beam Production Line takes lead both in China and Overseas market;

    5) These BOX Beam Manufacture machines can work individually, or integrally as Automatic or semi-automatic

      BOX Beam Manufacture Line assisted with conveyor /Auxiliary equipment like steel conveyor or flipping 

     equipment;

   2. Process Technology in the BOX Beam Production Line:
