T851 rail tyres for wagon 851mm diameter for Thailand railway forging and hot rolled production

Kingrail applied A high-strength light-weight rail vehicle tire and a production process thereof are used, and relate to the technical field of alloy preparation.

In order to provide an annular tire for the pressure rollers of a rolling press for crushing granular materials, the outer surface of which always has a high hardness and thus a high wear resistance, but its radially inner area is always 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 operation of the press roll by external pressure loading of the tire surface.

The tires of KINGRAIL are easy to transport, because they are a kind of pressure plate packaging of wheel tires, which includes a tire outer cylinder and at least three sets of fasteners. Outside the wheel rim, the outer cylinder of the rim includes several rim 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, The two spacers are respectively arranged on the upper end and the lower end of the outer cylinder of the tire. There are two through holes on the spacer block. The screw rod is set close to the inner circle of the outer cylinder of the tire, and the other double-headed 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.
