The production of railway wheels is controlled from the raw materials. The ingots used for wheels are transformed into continuous casting round ingots through converter, and the weight of each discharging is precisely calculated through the process design of software, and the discharging precision is guaranteed by automatic band saw machine. The round billet is heated cyclically in the heating furnace, and enters the extrusion process after dephosphorisation. Pre-forming, forming, rolling and punching of rail wheels are carried out by means of a forming machine + wheel mill + bending machine.
Rough Machining of Rough Rail Wheels
Masteel undertakes the inspection of the wheels, and is equipped with professional inspectors to carry out physical and chemical tests on the wheels after heat treatment to ensure that qualified products enter the machining process. Tianjun Machinery will use CNC vertical lathe to rough the rough wheel after inspection to remove the forged black oxide skin on the surface of the wheel.
Railway Wheel Ultrasonic Flaw Detector
Rough machined rail wheels are inspected by full-immersion ultrasonic flaw detector and then enter the finishing process to achieve the dimensional status required by the drawings.
Finishing and Dimensional Inspection
After ultrasonic flaw detection the rail wheels go into finishing and dimensional inspection to meet the customer's requirements for customised dimensions.
Rail Wheel Inspection
According to the standard requirements, the wheels are tested for surface hardness by fully automatic digital display door hardness tester, and the wheels are tested for static balance by centrifugal force vertical single-sided positioning static balancing machine. According to customer requirements, automatic marking machine is used to mark the qualified wheels to ensure product traceability. Finally, the finished wheels are inspected by automatic fluorescent magnetic particle flaw detector to ensure the surface is free of cracks. With the mature and professional MES system, the transmission of full-size inspection data of the wheels is completed, and then the wheels are packed and shipped.
Packaging and Delivery of Train Wheels
Qualified rail wheels, using screw-type packaging, 5 pieces to a pallet, after the customer orders, we will produce production drawings, packaging drawings, typing drawings to the customer to confirm, after confirmation of the production, about 45-60 days after the completion of the production of delivery
