Casting 610mm Railway Tyres For Locomotive Wagon Coach CB Certificate

Train wheel and tire rolling is a process of pressing and rolling steel ingots into train wheels. Wheels produced by this method are superior to cast wheels in terms of metallographic structure, mechanical properties and metal utilization.Kingrail produce wheels with a diameter of 508 to 1435mm.

In order to provide an annular tire for the pressure rollers of a rolling machine for crushing granular materials, the outer surface of which always has a high hardness and thus high wear resistance, but its radially inner region is In order to avoid tire cracks with low hardness, it is proposed according to the invention that the material of the tire (10, 11) consists of ductile iron with at least alloy elements Ni and Mo and a bainitic structure with residual austenite, ring wheel The surface layer (11) of the hoop (10) contains martensite in order to form a self-hardening surface, which is continuously reformed during the operation of the rollers by external pressure loading of the tire surface KINGRAIL uses a horizontal disassembly method and tooling assembly for locomotive wheels. The horizontal disassembly and assembly method of the above-mentioned locomotive wheel rim includes: Step 1. Fix the axle in the horizontal direction and keep the old tire in a vertical state, use a crane to set the tire heater on the old tire, and fix the old tire. For the tire heater; Step 2. When the tire heater works to the preset temperature, use the puller to pull out the old tire and the tire heater from the axle in the horizontal direction; Step 3. Use the crane to remove the old wheel Transfer the rim and the rim heater to the preset position; hoist the new rim into the rim heater; Step 4. Use the crane to hoist the new rim to the rim of the wheel to be installed; Press in the horizontal direction; Step 5. After the tire is cooled, remove the pressing tool and the tire heater to complete the installation of the new tire. By adopting the above method, the disassembly of the traction motor components and the repeated lifting and overturning of the axle can be avoided, and the replacement efficiency of the locomotive wheel hub can be improved.

KINGRAIL uses a pressure plate packaging for wheel tires, which includes a tire outer cylinder and at least three sets of fasteners. It includes a number of tire placement layers; each group of fasteners has the same structure and specification, and the fasteners include two spacers, two long double-ended screws and four nuts, and the two spacers are respectively arranged on the tires. On the upper and lower ends of the outer cylinder, there are two through holes on the cushion block, and the two cushion blocks are connected by two long double-ended screws and four nuts, one of which is close to the inner circle of the outer cylinder of the tire. set, and another double-ended screw is set close to the outer circle of the outer cylinder of the tire. The pressing plate type packaging of the wheel rim proposed by the utility model has the advantages of simple structure, convenient processing and manufacturing, and convenience for the transportation and storage of the wheel rim.
