Seamless steel pipe production line is mainly single-chain type cooling bed cooling bed, a double-stranded cooling bed, the new chain cooling bed, stepping rack cooling bed, screw-type cooling bed.

1, single-chain cooling bed
More use of single-chain cooling bed climbing structure. Cooling bed and fixed by the forward rail transport chain composed of a set of transmission. Placed between two steel dial grip forward transport chain, fixed steel rails bear the weight of the body. Single chain cooling bed transport chain finger means of the forward thrust friction of the steel pipe and the fixed rail to generate rotary motion, while relying on the weight of steel and the angle of lift, the steel pipe is always abutted against the forward transport chain finger, achieve a smooth pipe rotation.

2, double-stranded cooling bed
Duplexes cooling bed transport chain from the forward and reverse transport chains, positive and negative chain of transmission of each set. Placed between two steel dial grip forward transport chain, the reverse chain bear weight steel body. Duplexes cooling bed transport chain use the forward thrust of the steel pipe pulling claw run forward, using the inverse chain steel pipe friction generated continuous rotary motion. Reverse chain movement also makes steel always leaning forward transport chain, finger, smooth rotation and uniform cooling.

3, the new chain cooling bed
A combination of single-stranded and double-stranded cooling bed features cooling bed, cooling bed into the uphill sections and downhill sections. The uphill sections of the transport chain by the forward and reverse transport chain consisting of a double-stranded structure, positive and negative together to make steel continues to rotate forward, doing sport climbing. Downhill section of the forward transport chain and single-stranded structures arranged in parallel steel rails, relying on weight to achieve rotation, do landslide movement.

4, stepping rack cooling bed
Stepping rack cooling bed bed composed by two racks, assembled in a fixed beam, called static rack, another assembly in moving the beam, called the move a rack. L The agency action, moving the pipe rack will hold up the rise, due to an inclined angle, steel rolling when it is lifted once along the tooth. Move up to the highest gear position, stepping body movements so that the moving direction of the rack to the cooling bed one step away from the output. Lifting mechanism continues to operate, drive and move the rack dropped into a given rack alveolar steel, steel toothed rack along a fixed rolling once again, after moving back to the initial position of the rack, complete a cycle.

5. Screw the cooling bed
Main drive screw is cooled by means of the screw and fix the cooling of the gantry and other components, the screw including a screw rod and screw helix. Face fixed cooling gantry above the spiral rod above and below the spiral, steel body weight is borne by the fixed cooling stand. Main drive screw driven synchronous rotation, spiral screw driven steel roll forward on the fixed bench cooling, cooling. Single chain does not fit the cooling bed continuous operation, better cooling bed duplexes, the new cooling bed chain effect and low cost, stepping rack cooling bed is generally used in large or high profile production lineComputer Technology Articles, screw-type cooling bed are generally smaller diameter seamless steel pipe for cooling.

Heat treatment services for stainless steel and metal alloys

Solution annealing (also referred to as solution treating) is a common heat-treatment process for many different families of metals. Stainless steels, aluminum alloys, nickel-based superalloys, titanium alloys, and some copper-based alloys all may require solution annealing.

The purpose of solution annealing is to dissolve any precipitates present in the material, and transform the material at the solution annealing temperature into a single phase structure. At the end of the solution annealing process, the material is rapidly quenched down to room temperature to avoid any precipitation from occurring during cooling through lower temperature ranges. The single phase solution annealed material will be in a soft state after treatment.

The solution annealing treatment is required prior age hardening / precipitation hardening. The single phase microstructure created during solution annealing is required prior to age hardening, such that only the precipitates formed during age hardening will be present in the final product. The composition, size, and quantities of those precipitates formed during aging will determine the final product's hardness, strength, and mechanical properties after aging. It is critical that the structure be properly solution treated prior to aging in order to meet all of these requirements.

High-quality solution heat treatment

We recognize how important it is to our clients that the finished product we create demonstrates exceptional quality, and purity. To achieve this goal, we have invested heavily in our machinery, as well as implemented rigorous quality-control standards that ensure your work is completed to the very highest standard at every stage of solution heat treating. Our experienced team is able to successfully undertake heat treatment solution on a wide-variety of projects.

Definition of Cast Roll and Forged Roll

We will introduce cast roll and forged roll.

Forged rolls offer outstanding internal and surface soundness and meet customers’ requirements for strength, hardness, and reliability. Manufacturer produces forged rolls on advanced liquid forging hydraulic presses and heat treat by means of double and progressive induction to guarantee that our products have excellent levels of chemical pureness, solid metallurgic structure, and high resistance. The Reinosa steel plant’s latest developments in forged back-up rolls produces a superior product compared to cast back-up rolls. The structural homogeneity of forged rolls enables optimal performance in the mill.
