The main products of our company include welding pipe roll die and cold roll forming die.Based on the demand of customers,our company undertakes various round pipe,cold roll formed,round-square,directly square,double curved surface straightening roll and double involute die,etc. with materials of GCr15, cR12, Cr12MoV, SKD11, D2, Cr12Mo1V1, 3Cr2W8V, H13, 9Cr2Mo, and wear resistant RE high chrome cast iron.
Round pipe die covers various sizes of dia 8-711mm,and the side of square pipe die can be as long as 600mm.
U-shaped die can be 630×432×6,while U-shaped,T-shaped,Z-shaped and V-shaped steel piles can also be made.
Our company also designs and manufactures abnormally shaped dies of shapes according to customers' requirements.
A.Advanced groove deformation technology
After years of practice and exploration, our company starts from the corporate status quo, using a
combination of molding concept, that one set of rollers can produce dozens of standard square and
rectangular tube, to achieve roll change not unloading roll axis, the change time is greatly reduced, the unit
performance greatly improving , roll costs being reduced .
B.Strict raw material control
1.Germany imported portable spectrum analyzer
(Handheld * Fluorescence BRUKER SI TITAN MODE1600 ) Inspect the chemical composition of raw materials.
2.Metallurgical Microscope MV6000
Monitor the transformation process of the fiber tissue before and after heat treatment quenching
3.Germany imported desktop direct reading optical spectrum analyzer
Inspection of the chemical composition raw materials
4.Digital ultrasonic flaw detector
Flaw detection for the raw materials, heat-treated roll, finished products before shipment.
C.Professional heat treatment technology
Unique heat treatment technology gives full play to comprehen-sive mechanical property of the material, and the roll has better
characteristics of wear resistance, durability and fatigue resis-tance.
During heat treatment process, computer control is applied(±1°)to ensure quenching quality.
D.Excellent equipment is an important guarantee to make quality rollers.
E.Roller quality was widely praised by users due to its strict quality standard and meticulous product inspection.
