Device and method for improving metal wire utilization rate

Abstract

The invention relates to a device and method for improving the utilization rate of metal wires. The device comprises an outer baffle, sliding trolleys, inner baffles, a lead screw, rails and nuts, twosliding trolleys are oppositely arranged on each rail and are slidably connected with the rail, one end of the lead screw is provided with the left-hand threads, and the other end of the lead screw is provided with the right-hand threads. The two ends of the lead screw are matched with the corresponding nuts, the nuts are fixedly connected with the bottoms of the sliding trolleys, and the end ofthe lead screw is connected with a handle. The arc-shaped inner baffles are fixed on the sliding trolleys, the outer baffle is cylindrical, and the rails are distributed at the bottom of the outer baffle. The inner baffles on the sliding trolleys are coaxial with the outer baffle and are arranged in the outer baffle in the radial direction. The device and the method have the advantages that the metal wire coils are effectively prevented from being piled up and are prevented from being scattered, bent and knotted after being piled up, the wire coils are kept orderly all the time, and thereforethe metal wires can smoothly enter a guide-in roller of the metal wire machine in a smooth state; the utilization rate of the metal wire coils is improved, the zero loss is achieved, and the smeltingcost of a refining LF furnace is reduced.

Description

technical field [0001] The invention relates to an auxiliary equipment for continuous casting and refining, in particular to a device and method for improving the utilization rate of metal wires such as high-alumina wires and calcium-silicon wires. Background technique [0002] In the continuous casting and refining LF furnace of the General Steelmaking Plant, aluminum wires, silicon-calcium wires, etc. are used when fine-tuning the composition of molten steel. When the existing aluminum wire coils and silicon-calcium wire coils are produced by the supplier, the order of arrangement is to arrange a metal wire from the inside to the outside, from top to bottom and then from bottom to top, reciprocating (hollow, diameter 600mm), until the After all winding of the fixed length (outer diameter 1400mm), the finished product will be sent to the site for use, see figure 1 . When in use, lay the wire coil flat, tap from the core, and introduce it into the metal wire feeder lead-in...

AI Technical Summary

Problems solved by technology

When the number of remaining layers is reduced to more than 10 layers, the stability of the wire coils will become poor, and there will be confusion, falling, disorderly arrangement, and even "messy" phenomenon. Entering the molten steel tank through the metal wire feeder, the remaining metal wires are forced to be scrapped, causing serious waste and increasing the cost of smelting
