After leveling, the stainless steel plate is cut in both length and width directions using two computer-controlled underwater plasma cutting machines, and then sharp burrs are removed using a polishing tool.
Product processing process
The stainless steel black skin raw material is transferred to the JDKC production factory for the following process: heat treatment, melting, cutting, shot blasting, pickling, quality inspection, and packaging. The stainless steel produced by Dageng has various materials and sizes, such as 304, 304L, 316L, 317L, 321, duplex steel, etc. Thickness range: 6-120mm
Solid solution/water quenching
The outsourced black panels or coils are transported to Dageng stainless steel and annealed in a 1050C-1150C furnace, followed by automatic quenching with quenched water to achieve the goal of stable metallographic structure and solid melting.
leveling
After solid Enthalpy of fusion treatment and water quenching, the plates with a thickness of more than 40mm shall be leveled with an oil pressure leveler, and the plates with a thickness of 4mm-40mm shall be leveled with a silver leveler.
Shot blasting and pickling
The cut stainless steel plate enters a computer-controlled roller table in a horizontal state for shot blasting and acid washing to remove surface oxide skin, form a Cr, 0, protective film, and become white stainless steel.
Quality inspection and coding
After quality inspection on the roller table, the stainless steel plate after pickling is automatically sprayed with code according to the material, size, and execution standards of the plate.
Weighing and packaging
The stainless steel plate after printing will be accurately weighed and stored if needed. Final packaging.
