Seamless Steel Tube Production Line

Seamless steel pipe production line is mainly single-chain type cooling bed cooling bed, cooling bed duplexes, new chain cooling bed, stepping rack cooling bed, screw-type cooling bed. Climbing cooling bed multi-use single-stranded structure. Cooling bed and fixed by the forward rail transport chain composed of a set of transmission. Pipe placed between two dial grip forward transport chain, fixed rails bear the weight of steel pipe body. Forward delivery using a single-stranded chain of the cooling plate finger thrust friction of the steel pipe and the fixed rail to produce rotary motion, while relying on the weight of the steel pipe and the lift angle of the steel pipe is always in the forward direction against the finger of the transport chain, achieve a smooth pipe rotation. Cooling bed duplexes by the forward and reverse transport chain transport chains, positive and negative chain of each set of transmission. Pipe placed between two dial grip forward transport chain, the reverse chain bear the weight of steel pipe body. The use of double-stranded cooling bed transport chain pull forward thrust to make steel claw run forward, using the inverse of the chain continued to produce the steel pipe friction rotary motion. Reverse movement also makes steel chain always leaned forward transport chain finger, smooth rotation and uniform cooling. Combination of single-stranded and double-stranded cooling bed cooling bed features cooling bed into the uphill sections and downhill sections. Uphill sections by forward and reverse transport chain transport chains of double-stranded structure, the pros and cons together to make steel continues to rotate forward, doing sport climbing. Downhill section of the forward transport chain and single-chain structural steel rails arranged in parallel, relying on weight to achieve rotation, do the landslide movement. Stepping rack cooling bed bed composed by two racks, a fixed beam assembly, called a static rack, another assembly moving beam, called the move a rack. L The agency action, moving the pipe rack rise will hold up, as has the tilt angle, steel rolling when it is time to hold up along the tooth. Gear up to the highest position, stepping agency action to make the move rack cooling bed output direction a step. Lifting mechanism to continue the action, driving and moving the rack dropped into a given rack steel gullet, the pipe along the toothed rack set rolling once again, after moving back to the initial position of the rack, complete a cycle. Screw drive from the main cooling means and the fixing screw of the cooling stand, etc., and the screw includes a screw rod core screw spiral. Fixed gantry face higher cooling auger core above and below the spiral, the body weight is borne by a fixed pipe cooling stand. Main drive screw driven synchronous rotation of the screw spiral steel pipe rolling push forward on the fixed bench cooling, cooling. No cooling bed is not suitable for single-strand continuous operation, better cooling bed duplexes, new cooling bed chain effect and low cost, stepping rack cooling bed configuration is generally used in large or high production line, Usually the cooling bed for cooling the screw of a smaller diameter pipe.
