A kind of steel wire take-up method

Abstract

The invention discloses a steel wire winding method, which comprises the following steps: step 1, the steel wire is fixed on the outer surface of the drum through the rotation of the drum, continuously drawn for 40 to 80 turns, and the wire frame is raised to rise and meet the drum For docking, drop the steel wires to the neutral position of the guide rod, and bundle the fallen steel wires into strands; Step 2, continue to rotate the reel, accumulate 40 to 80 turns of steel wires on the reel, and rotate the synchronous take-up frame independently in the same direction It is 60° to the winding shape of the reel. Raise the take-up frame to make the guide rod dock with the reel, take off the steel wire on the reel and drop it to the neutral position of the guide rod, so that it is centered with the orthographic projection of the last bundle of steel wire Symmetrically, tie into steel wire strands; step 3, repeat step 2 until stacked 3 to 12 layers or enter the wire take-up machine, and the wire take-up ends. The steel wire of the invention is heated more evenly during the heat treatment in the furnace space, has better heat permeability, better temperature drop consistency, uniform steel wire quality, and the uniformity fluctuation of the blow rod strength is less than 10MPa.

Description

technical field [0001] The invention relates to a wire take-up method, in particular to a steel wire take-up method. Background technique [0002] At present, the heat treatment of semi-finished steel wires of most heat-resistant alloys and high-temperature alloys is mainly produced by online IPH pipeline-type hydrogen or ammonia atmosphere protection devices and well-type furnaces; the online steel wire heat treatment cooling method is red-hot steel wire straight line Under the tension provided by the wire take-up device, it is passed into the overflow water tank for cooling treatment. The cooling method of the pit furnace is mainly to hoist the material rack or loading device to the fixed water tank or oil tank by driving, and completely submerge the material rack to the liquid level. Hereinafter, simultaneously open the convection device at the bottom and the side of the tank body as required. [0003] The above method is more traditional and has some disadvantages. In ...

Problems solved by technology

In order to ensure the heating temperature of the steel wire, the online protective atmosphere IPH furnace usually has a very slow wire speed, and it is difficult to guarantee the heating temperature and holding time at the same time, so the steel wire produced usually has high strength and poor solid solution effect. , and the output is low; due to the hoisting method of the well-type furnace, the material rack is far away from the water tank or oil tank, which leads to a significant drop in the temperature of the outer layer of the coil, while the cooling of the inner layer is insufficient, resulting in fluctuations in the tensile strength of the cleaning rod, and transfer Oxidation on the surface of the steel wire due to process and cooling is difficult to remove

[0004] It is difficult for general vacuum solid solution oil cooling equipment to handle wire coils. On the one hand, it is because the diameter of steel wire coils is relatively large, with an outer diameter range of about 1200 mm. For equipment manufacturers, it is considered unconventional and large equipment. Customization is required; on the other hand, the winding and packaging method of the steel wire coil will cause the steel wire to be harvested as a "thick" relatively solid coil shape, which is very unfavorable for the coolant to penetrate the gap between the steel wires and take away the heat. In most cases, it is through the steel wire The heat transfer to and from the steel wire takes the heat away, resulting in insufficient cooling capacity
