1,Advanced technology:It is developed by absorbing advanced technology of steel lattice press welder from such developed countries as the United States,Japan and Australia,combined with concrete conditions of China`s raw materials. 2,High productivity:It adopts the technology of direct current two-stub single press welding. 3,Low energy consumption:Main part adopts intgrated structure of welding power source and press,short welding circuit,greatly decreasing idle power loss. 4,High automation:Input of flat steel and cross bar,output of automatically press welded linear steel lattice. 5,Easy operation:It adopts man-machine interface,intelligent parameter setting and digital state displaying. Process diagram (1) slitting line Hot-rolled steel in broadband Slitting Steel roll for the use of steel grate production line or purchase ready-made 6.5 meters below the flat length. Hot-rolled narrow strip (2) twisted square steel production line: Actinomycetes rod - Descaling - rotation-mode square steel drawing-twisting - Straightening Cutting Length Or purchase ready-made twisted length of 1050mm square steel (3) production line grating Flat steel+twisted bar→force welding→ Cutting edge → forming package → hot-dip galvanized welding → → packaging shipments
