Description
Technical Field
The utility model relates to a LF stove production process equipment especially relates to a long-life guider of LF stove wire feeding pipe.
Background
The wire feeding is a ladle refining technology appearing at the end of the 20 th century 70 years, and is mainly characterized in that Ca-Si wires, ferroboron, aluminum products and other alloys are made into cored wires, the cored wires are mechanically added into the deep part of molten steel, and refining treatments such as deoxidation, desulfurization, nonmetallic inclusion denaturation treatment, alloying and the like are carried out on the molten steel, so that the metallurgical process is improved, the purity of the molten steel is improved, the service performance of products is optimized, and the treatment cost is reduced. The wire feeding technique requires a special wire feeder to operate, and the wire is fed into the molten steel in the ladle through a wire feeding pipe. At present all wire feeding pipes are metal pipes, and the silk thread is put for the disc before getting into the wire feeding pipe, so the silk thread tensile atress can take place huge friction at the wire feeding mouth of pipe when getting into the wire feeding pipe, leads to the wire feeding pipe frequent deformation to shorten and need change, and the silk thread blocks when serious, leads to the silk thread to nip absolutely and makes production suspend, need threading again, wastes time and energy, influences the production rhythm, brings huge loss for the enterprise.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a LF stove wire feeding pipe long-life guider is provided can effectively avoid silk thread and wire feeding pipe frictional deformation and the disconnected accident of silk thread card, has realized LF stove wire feeding pipe long-life steady operation, has provided manufacturing cost of enterprise.
For solving the technical problem, the utility model discloses the technical scheme who adopts does:
a long-service-life guide device for a wire feeding pipe of an LF (ladle furnace) comprises a guide pipe and a guide roller set; the guide tube is connected to the lower opening of the wire feeding tube in a horn shape, and the guide roller group is fixed to the lower opening of the wire feeding tube by a plurality of guide rollers in an end-to-end connection mode.
According to the long-service-life guide device for the wire feeding pipe of the LF furnace, the guide roller set comprises a plurality of guide rollers, the roller shafts of the guide rollers are connected end to form a polygon, and the axis of the wire feeding pipe passes through the center of the polygon; the guide roller group is fixed on the inner wall of the lower opening of the wire feeding pipe through a plurality of fixing rods fixed with the roller shaft.
Foretell LF stove wire feeding pipe long-life guider, the axis of all roll shafts is in on the same horizontal plane after guide roller set and wire feeding pipe are fixed.
According to the long-service-life guide device for the wire feeding pipe of the LF furnace, the diameter of the upper port of the guide pipe is matched with that of the wire feeding pipe, the upper port of the guide pipe is fixedly connected with the lower port of the wire feeding pipe, and the lower port of the guide pipe is a horn mouth; the axis of the guide tube is coincident with the axis of the wire feeding tube.
The utility model discloses a use method does: when the wire feeder feeds wires, the alloy wire coil enters the wire feeding pipe from the horn mouth of the guide pipe, and does not rub with the lower mouth of the wire feeding pipe, so that the wire feeding pipe is protected; meanwhile, when the silk thread enters the silk feeding pipe from bottom to top and is skewed, the friction force is eliminated along with the rotation of the guide roller when the silk thread contacts the guide roller surface at 360 degrees around the silk thread, so that the direct contact friction between the silk thread and the silk feeding pipe is avoided, and the blocking of the silk thread is avoided.
The utility model has the advantages that:
the utility model discloses can effectively avoid closing gold wire and feed pipe contact friction and card disconnected silk thread accident, the feed is efficient, simple structure, and is with low costs, and longe-lived, realized LF stove feed pipe long-life steady operation, greatly reduced the manufacturing cost of enterprise.
