PROBLEM TO BE SOLVED: To provide near-net shape continuous rolling equipment for manufacturing a linear guide raw material.SOLUTION: Near-net shape continuous rolling equipment 10 for manufacturing a linear guide raw material comprises a raw material sending/feeding mechanism 20, a tension control mechanism 30, and at least one set of heating rolling means 40. The raw material sending/feeding mechanism 20 transfers a raw material, and the tension control mechanism 30 controls the tension of the raw material 21, and holds an excessive transfer speed and transfer tension. The heating rolling mechanism 40 comprises an electromagnetic induction heating system 41 and a four-roller type near-net shape rolling mechanism 42. The electromagnetic induction heating system 41 has a temperature return control mechanism 411 and a frequency/power control system 412. The temperature return control mechanism 411 detects a surface temperature of the raw material 21, and the frequency/power control system 412 heats the raw material 21, and holds a temperature suitable for rolling. The four-roller type near-net shape rolling mechanism 42 applies rolling-type plasticity processing to the raw material 21 by rolling rollers which are arranged in a shape of four-piece planetary gears, and rolls a periphery of a cross section of the raw material. |
