The reheating furnace is a roller sideloading sideout walking beam type reheating furnace. The whole wire rod mill line consists of 6 roughing mills, 8 intermediate rolling mills, 4 prefinishing mills, 8 finishing mills and 4 reducing and sizing mills. The small extension precision rolling is realized.
These mill rolls are manufactured in dimensions of up to Ø400mm outside diameter and a maximum thickness of 200mm. Application of Kennametal Tungsten Carbide Rolls for Wire Rod Rolling Wire and rods are hotrolled between two rolls. Work material deforms and achieves the desired shape and size of the wire or rod.
The main feature of Morgan's fifthgeneration highspeed wire rod mill is high speed and heavy load. Based on this feature, it requires oil film bearings to have the following characteristics: 1, The oil film bearing has a good heat dissipation capacity, because highspeed operation will definitely bring about an increase in temperature;

spit large and small circles refers to the different diameters of the coils spit out by the wire rod mill laying head, which is mainly due to the unstable tension between the pinch roll and the wire rod mill laying head. The solution should start from two aspects: First, maintain the stable clamping of pinch roll.
Also known as ring rollers, these curvers shape wire, rods, and flat stock into curves and circles. Turn the handle to drive material through the steel rollers. With each pass through the rollers, tighten the tensioner knob in small increments to gradually increase the curve.. Curvers with stand come with three sets of rollers— one for flat stock and two for wire and rods.
Unmatched startup reliability. Engineering services to match PURCHASER's requirements. Southwire's SCR® system is an advanced process for the continuous production of copper rod.
