[0039] High-grade-resistant high-strength stainless steel wire processing technology for ships, including the following steps:
[0040] Step, the stainless steel wire processed by the vomer is cooled to 1100 ° C by air cooling, and the solid solution is following;
[0041] In step one, the temperature of the solid solution furnace is maintained at 1080 ° C ± 10 ° C;
[0042] In step one, the stainless steel wire is austenitic stainless steel wire;
[0043] Step 2, the stainless steel wire is collected in the solid-dissolved furnace furnace, and the stainless steel wire after the school is completed secondary heating in the solid solution fell;
[0044] In step two, the high temperature gas obtained by cooled the nomatic machine processing of the stainless steel wire is inhaled, and the stainless steel wire in the furnace body is heated twice. After the second heating, the high heat gas discharges the furnace body and sent to The heat exchanger group re-uses the waste heat, and the waste heat is fully utilized; and the secondary heating is performed first, the main purpose is to avoid the temperature of the stainless steel wire in the process, and the other Aspects allow stainless steel wires to enter the next step in a high temperature;
[0045] Step three, using a laser cutting machine to cut out the wire groove outside the two heated stainless steel wire;
[0046] The laser cut has a high cutting accuracy, does not produce mechanical stress, and the advantages of high cutting surface are high. The surface of the secondary heated stainless steel wire reaches a higher temperature, which can cause the laser cutting machine to cut at lower frequencies and power (cutting Process, the frequency of the laser cutting machine is 200 Hz, the power is 600W) to achieve energy saving and reduce the purpose of the equipment purchase cost;
[0047] In step two and steps, in advance, the collections can be performed to ensure the axial direction of the laser cut and the axial direction of the stainless steel wire, in order to carry out the subsequent process;
[0048]Step 4, the stainless steel wire cuts the outgoing groove and passes through the mold with the mold hole, and the bumps in the mold hole are shaped and extruded on both sides of the wire slot;
[0049] In step four, the processing method of stainless steel wire and the cold rolling and the cold rolling and the rolling of the pipe pipe exit end, the difference is that the wire groove position temperature of the wire is 1200 ° C, and the remainder temperature remains 1080. ° C ± 10 ° C, the temperature is lower than the temperature of the vomiting tube outlet end wire, and it is significantly higher than the temperature of the cold pull, and the stainless steel wire remains high in the temperature state; because of the second heating and The high temperature cutting of the laser, the position temperature of the stainless steel wire is significantly higher than the temperature of the other position, so the remaining parts of the stainless steel wire pass through the mold hole of the mold, the remaining parts of the wire tank are not easily deformed, and the stainless steel wire is still available. Maintain high precision, and the shape and structure inside the line slot are easier to form;
[0050] Step 5, the finished stainless steel wire is maintained after 3 minutes of the furnace body for 3 minutes, and the water is cold to normal temperature;
[0051] It should be noted that the heat preservation is a time required for stainless steel wire to be transported from the mold to the exit of the furnace. On the one hand, the newly operated wire groove is solidified, and the other aspect is equivalent to The stainless steel wire is annealing, which is conducive to maintaining the intensity, finishing and corrosion resistance of the stainless steel wire.
[0052] Step 6. The stainless steel wire after the cold is dry, wound into a bundle, sent to the deep cold machine to carry out cold, heat insulation for 1 hour, to further reduce the amount of residual Aoplasia in steel, improve stainless steel wire Strength and wear resistance;
[0053] Step 7. The stainless steel wire after deep cold treatment is 160 ° C for 1 hour, and the final finished product is obtained.

[0055] 5, the wire slot processing process of stainless steel wire is carried out in the solution furnace, combining the line tank processing and solid solution treatment into a step, saving the time required for processing, and the stainless steel wire is processed after the wire groove The inner wall also gave a solution treatment, ensuring the intensity, finish and corrosion resistance of the stainless steel wire, and also fully utilized a relatively constant temperature environment in the solution furnace to ensure a smooth processing with a more complex structure. conduct;
