Problems solved by technology

[0002] At present, with the continuous development of the economy, the urban land traffic is becoming more and more congested. In order to solve the traffic jam problem, many cities widen the roads and build subways, but the widening of the roads requires a lot of land resources, and the demolition of buildings and vegetation on both sides of the road The cost is high, and the construction of the subway requires high investment costs and a long construction period. During the construction period, it will cause further road congestion. In addition, land traffic is easy to cause traffic accidents. Freezing and snowstorms will also interrupt land traffic, causing serious damage to the country and society. huge loss

Abstract

The invention discloses a preparation method of a suspended carrying track and the suspended carrying track. The preparation method of the suspended carrying track comprises the following steps of: by taking a smelted high purity alloy as a raw material, processing the raw material into a suspended carrying track blank; forging and rolling the suspended carrying track blank to obtain a suspended carrying track blank product; and polishing the suspended carrying track blank product to obtain the suspended carrying track, wherein the high purity alloy contains the following components in percentages by weight (wt%): 0.30-0.40wt% of vanadium, 11.00-12.00wt% of chromium, 0.22-0.25wt% of carbon, 1.20-1.40wt% of nickel, 0.70-0.80wt% of manganese, 0.0013-0.0021wt% of titanium, 0.10-0.20wt% of silicon, 0.30-0.40wt% of molybdenum and the balance of iron and inevitable impurities. The suspended carrying track prepared by the preparation method of the suspended carrying track is smoother.
