The rolled steel plate of a cold-rolled sheet project is annealed, and the annealing method is an all-hydrogen bell annealing furnace. The unit is located on the AB span of the third area of the main workshop, between lines 310 and 324 (see the floor plan). 316L stainless steel vacuum brazing process The whole set of units has imported technology from the German LOI company and has 17 furnaces in total. Each annealing furnace is composed of hearth, inner cover, outer cover, cooling cover, quick cooling system, medium pipeline, hydraulic control system, etc. (see Figure 1). Vacuum heat treatment of aluminum alloy die castings The installation elevation is on the steel structure of -40mm (outside: -30mm), and the diameter of the hearth is 2.81 meters. The inner cover, heating cover, cooling cover, quick cooling system and combustion support system of the bell furnace are all provided by the manufacturer Tianjin LOI. Vacuum Oil Quenching for steel hardening heat treatment The company assembles the whole and only needs to be hoisted as a whole, so the installation focuses on the installation of the furnace platform, surrounding equipment and the installation of the furnace bottom medium pipeline. This plan is specially compiled for the better construction of the whole unit.MIM degreasing and sintering for ceramic hard alloy
