    Main features

    1. Reducing rolling mills are specially designed to reduce round, metal sheathed tubular elements. They contain a number of pairs of driven rolls, mounted in a V-shaped bearing box assembly.
    2. Sintered carbide rolls(Cr12,W18Cr4V) are recommended for annual production more than one million meters of hard material. The life can be 5~10 times than tool steel.
    3. 12 stations can process thicker tubes and higher reduction rates than 8 stations.
    4. The min. length of tube:110mm
    5. Efficiency: 18m/min.
    6. Tube diameter after compressing: Φ5.2mm~Φ19.0mm
    7. The max. diameter before compressing: 21mm
    8. After compressing, the straightness can reach 1:300, and the roundness can reach 0.07mm.
    9. The minimum safety distance between tubes should be 500mm, or one third of the element length.

    Construction of Reducing rolling mills

    1. Machine stand with motors and gear boxes
    2. Transmission shafts
    3. Bearing box assembled with rolls(high speed steel or tungsten carbide)
    4. Simple type of straightening device

    Rolling mill for Double layers of cooper tube

    1. Twelve groups of rolling mill, a single motor is decelerated through a cylindrical gear box,to transmit the power to the roller shaft through the cross drive shaft,which drives the roll wheel to rotate,then each group completes the cold extrusion. The power of a single group of motors is 1.1Kw.
    2. The roller is made of Cr12MoV, heat treatment hardness HRC60∽62.
    3. The roller shaft is made of 40Cr alloy structural steel, which has been quenched and tempered by high frequency. The hardness of bearing mating surface and roller mounting surface is HRC58∽60.
    4. Needle bearing ⅠKOBR223020, plane bearing 51108.
    5. Rolling roundness tolerance ±0.03mm, straightness tolerance 1000mm, bending less than 0.5mm, no rotten head bending.
    6. The total power is 13.2Kw.
    7. Dimensions: length 1900x width 1800x1200mm, entrance center height 930mm, weight about 3000KG.
