Problems solved by technology
[0003] With the splash or slag overflow due to the change of molten iron composition and oxygen lance position during smelting, slag overflow during slag dumping, and splashing during tapping, etc., it is easy to cause red slag on the track floor, and The uneven distribution of thermal stress leads to thermal deformation of the track bottom plate and embedded plate, causing cracking of the weld seam, which directly affects the running track of the vehicles under the furnace, and then is forced to stop the furnace to replace the bottom plate and other maintenance, which seriously restricts the production rhythm and effective operation rate; therefore , the present invention proposes a track floor installation structure under the converter to solve the deficiencies in the prior art

The invention provides a rail bottom plate mounting structure under a converter, and relates to the field of rails under the converter. The rail bottom plate mounting structure comprises rail foundation steel frame molds, sectional type bottom plates, first sectional steel beams, second sectional steel beams and a rail body, a rail bottom plate is arranged on the rail foundation steel frame molds, a plurality of groups of first sectional steel beams are spliced to form a first rail steel beam, a plurality of groups of second segmented steel beams are spliced to form a second rail steel beam, the first rail steel beam and the second rail steel beam are symmetrically arranged above the rail bottom plate, mounting holes are formed in the rail bottom plate on one side of a steel beam protection structure, a plurality of groups of mounting holes are formed at equal intervals, and foundation screw rods are arranged in the mounting holes; and by arranging the foundation screw rods, thermal stress generated by the rail foundation bottom plate can be impacted against tensioning force of the embedded foundation screw rods through the foundation screw rods, it is guaranteed that an under-converter rail is not subjected to local deformation caused by red slag baking, stable operation of the under-converter rail is guaranteed, and the overhaul and maintenance cost of the under-converter rail is reduced.
Description
technical field [0001] The invention relates to the field of the lower track of the converter, in particular to a bottom plate installation structure of the lower track of the converter. Background technique [0002] The installation structure of the track floor is mainly to ensure the smooth operation of the vehicle under the furnace. The existing installation structure of the track floor under the furnace is installed on the foundation embedded plate, and the embedded plate is installed every 600mm-1000mm. The embedded plate uses δ = 20mm steel plate, the pre-embedded plate is welded with Φ18mm and Φ20mm rebar steel when making molds through the base to make the pre-embedded root fixed and stressed; when the vehicle load is running under the furnace, the load is transferred to the track, bottom plate, and embedded plate through the wheels to the base; [0003] With the splash or slag overflow due to the change of molten iron composition and oxygen lance position during sm...
