Embodiment Construction

[0044] Such as figure 1 As shown, the 450-ton electroslag remelting furnace of the present invention includes a column device 10, a cross arm 20, a lifting platform 30, an electric flat car 40, and a crystallizer 50;

[0045] The column device 10 includes a first column, a second column, and a third column. The centerlines of the three columns 100 are located on the same circumference. , and the lower end surfaces are respectively on the same horizontal plane. The three uprights 100 are fixedly connected to the foundation through respective upright bases.

[0046] The middle part of the three columns 100 is provided with column intermediate curved beams 11, and the two intermediate curved beams 11 respectively connect the first column and the second column, and the first column and the third column into one body. The space between the second column and the third column is used for the entry and exit of objects such as the electric flat car 40 and the electroslag remelted ste...

Abstract

The invention discloses a 450-ton electroslag remelting furnace, which comprises an upright post device, transverse arms, a lifting platform, an electric flat carriage and a crystallizer. The upright post device comprises three upright posts; each upright post is provided with a transverse arm; a connecting end of each transverse arm is connected with an upper part of the upright post through a transverse arm connecting device; a free end of each transverse arm is provided with an electrode holding jig, and the electrode holding jig makes the electrode fixed on the transverse arm; each transverse arm is provided with a transverse arm lifting device and a transverse arm rotating device; the lifting platform is arranged in a space enclosed by the three upright posts; the lifting platform isslidably connected with the lower part of the upright post; the lifting platform is provided with a platform lifting device; the platform lifting device drives the lifting platform to move up and down; the electric flat carriage is arranged on the lifting platform; the top of the electric flat carriage is provided with a water-cooled bottom plate; and the crystallizer is arranged on the water-cooled bottom plate. The furnace can produce electroslag remelting steel ingots with the largest diameter of 3,600mm, the highest height of 6,000mm and the heaviest weight of 450 tons.

Description

technical field [0001] The invention relates to electroslag smelting equipment, in particular to a 450-ton electroslag remelting furnace. Background technique [0002] The existing electroslag smelting technology uses a 200-ton three-phase three-rocker bipolar series electroslag remelting furnace, which can only produce electroslag ingots with a maximum weight of no more than 200 tons, but the internal components of million-kilowatt nuclear power units use stainless steel Large forgings, large nuclear power forgings such as steam turbine low-pressure rotors, generator rotors, evaporator tube sheets, and large backup rolls for the second and third generation million-kilowatt nuclear power units require a large number of large forgings weighing more than 200 tons of electroslag ingots, the existing electroslag smelting equipment cannot meet the needs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a 450-ton elect...
