Seamless steel pipe production line of the
main cooling bed types have Single strand cooling bed, Duplexes cooling bed,
New Chain cooling bed, Stepping rack type cooling bed and Screw type cooling
single-stranded cooling bed
Single strand cooling bed more adopts
climbing structure. Cooling bed composed by forward transport chain and fixed
rail, with a set of transmission. Steel pipe placed in the forward transport
chain, fixed rail bear the weight of steel. Single-stranded cooling bed use driving
force of forward transport chain and friction of fixed rail to rotate the steel
pipe, while relying on steel weight and the angle of lift, to make the pipe always
closed in the forward transport chain, achieving steel tube rotates smoothly.
Duplexes cooling bed composed by the
forward and reverse transport chain, forward and reverse chain with a set of
transmission. Steel pipe placed in the forward transport chain, reverse chain
bears the weight of steel. It use driving force of forward transport chain to
run pipe, and using the friction of reverse chain to make the steel pipe carry
on a continuous rotational movement. Movement of the reverse link makes the
pipe always closed in the forward transport chain, achieving steel tube rotates
smoothly and uniform cooling.
new chain cooling bed
A combination of the characteristics of single-stranded
and double-stranded cooling bed, the cooling bed is divided into uphill and
downhill sections. Uphill section is a double-stranded structure composed by forward
and reverse transport chain, positive and negative interaction together to make
steel continuous rotation and forward, doing climbing movement. Downhill
section is a single chain structure composed by the forward transport chain and
steel rails, relying on weight to achieve rotation and landslide movement.
type cooling bed
Screw-type cooling bed is composed by
gearing, screw and fixed cooling stand and so on, screw including screw rod
core and screw spirals. Fixed cooling bench face is higher than top of screw
rod core and below screw spirals, the weight of steel bear by fixed cooling
stand. Main gearing driven screw synchronously rotating, screw spirals pushed
steel to roll forward in fixed cooling bench.
Single-strand cooling bed is not suitable
for continuous operation, duplexes cooling bed has a better effect, New Chain
cooling bed has a good effect and low cost, Stepping rack type cooling bed is
generally used in large or high configuration of production line, Screw-type
cooling bed for cooling generally smaller diameter of the pipe.
