Embodiment 1
[0030] A production process for high-strength light-weight rail car tires, the specific production process is as follows:
[0031] (1) The raw material iron-silicon block, iron-manganese block, pure iron block, iron-magnesium block, iron-aluminum block, iron-chromium block, iron-copper block, iron-nickel block, iron-molybdenum block, iron-vanadium block and iron-titanium block according to certain Mass fraction is weighed;
[0032] (2) Put the weighed pure iron block into the electric furnace for smelting, smelting until the content of carbon element in molten steel is less than 0.82%, the content of sulfur is less than 0.06% and the content of phosphorus is less than 0.04%, to obtain the primary molten steel, by adjusting The carbon content can control and change the strength of the tire. At the same time, the reduction of the sulfur and phosphorus content can prevent the internal space of the tire obtained in the later refining, the strength is small, and it will increase th...

Abstract
The invention discloses a tyre for high-strength light rail car and a manufacturing technology thereof, and relates to the technical field of alloy preparation. The tyre comprises an outer tyre, a clamping seat is fixedly and integrally connected to the middle of the inner surface of the side wall of the outer tyre and comprises a clamping platform and a stop ring integrally and fixedly connectedto the outer side of the bottom surface of the clamping platform, wherein the clamping platform and the outer tyre are coaxially arranged, and several threaded through holes are formed in the end surface of the clamping platform; a tread ring is integrally and fixedly connected with the bottom end surface of the outer tyre, the surface of the tread ring is an annular surface completely coincidingwith the bottom surface of the outer tyre, the inner side of the annular surface vertically bends outward to form an arc tread surface extending downward and outward, and the outer side of the annularsurface vertically bends outward to form an outer arc surface with the bottom end coinciding with the outer side of the arc tread surface; the tread surface of the tyre is made into an oblique surface of 5 degrees, therefore the wheel set mass can be reduced, wheels can conveniently pass curve rails, the tread surface can be uniformly abraded, by lowering the gravity center of the car, the wheelset mass is reduced, and the flexibility of the rail entering of rail wheels is improved.
Description
technical field [0001] The invention relates to the technical field of alloy preparation, in particular to a wheel tire for high-strength light rail cars and a production process thereof. Background technique [0002] The track wheel train of a rail vehicle is the main moving device for the vehicle to move on the rails, so the design of the track wheels should meet the size, strength and shock absorption requirements of the locomotive running on the track. On the other hand, when the vehicle is running on the road, the track wheels must also be able to be retracted and fixed, so as not to affect the normal operation of the rubber wheels. Specifically, the design of the track wheel has the following two points: the size of each component of the track wheel system meets the requirements of track running and meets the strength requirements; the track wheel system must have an excellent shock absorption effect and be stable and reliable when running on the track. [0003] Due t...
