Description
Technical field
The present invention relates to the manufacture method of bullet train employed braking device, particularly a kind of axle-mounted brake disk.
Background technique
At present, it is big that the employed braking device of bullet train requires to have braking force, reliable performance, the characteristics that thermal fatigue property is good, attriting performance is good, its significance of critical component alloyed steel axle-mounted brake disk in the braking device is particularly outstanding, because brake disc must have high strength, high temperature resistant, high dense structure's property and good friction wear hardness, its technical requirements is very high, is mainly reflected in following several respects:
1, the material composition complexity of steel disk, alloy is more, and the content requirement of various alloys is very strict, in the alloy melting process, be difficult to control and grasp, more do not have relevant technical data and do reference, grope and summing up experience by the test of carrying out repeatedly entirely, carry out the tackling key problem of technology and technology.
2, the high-mechanical property of steel disk material, the impurity content that influences its performance is required very low, as long as its S of steel, P content be lower than 0.04% just passablely, and the S of alloyed steel axle-mounted brake disk material, P content requirement are lower than 0.020% and 0.025%.Impurity content is low more, and its relevant smelting technique requires also just high more, and the complexity of technology is just high more.
3, the zero defect requirement of steel disk integral body, according to " technical specifications that the JZP01 profile shaft is brake disk mounted ", product after the quenching with Subsequent tempering carries out the ultrasonic flaw detection inspection by GB7233 " Cast Steel ultrasonic flaw detection and quality grading standard ", should reach the first quality standard, cast steel product will be accomplished whole zero defect, its technical difficulty is very big, has only the special and stable casting technique of employing just can reach.
4, the high compactness of steel disk global tissue and special heat treatment process requirement, according to " technical specifications that the JPZ01 profile shaft is brake disk mounted ", tensile strength 〉=the 1200Mpa of steel disk bulk material, and specific elongation 〉=12%, reduction of cross sectional area 〉=25%, both required high intensity, also requiring simultaneously has good plasticity, and high strength and good plasticity are contradiction, and this contradiction is more outstanding concerning cast steel.How to accomplish that high strength and good and plasticity are contradiction, this contradiction is more outstanding concerning cast steel.How accomplishing that it is one of technical barrier of development alloyed steel axle-mounted brake disk that high strength combines with good plasticity, also is the bottleneck of the development of this project.
5, steel disk good high-temperature mechanical property and heat-resistant anti-fatigue performance, locomotive or motor-car are when carrying out emergency braking, the brute force friction of huge Brake Energy by alloyed steel axle-mounted brake disk and powder metallurgy brake lining friction pair converts the heat energy overwhelming majority to and absorbed by the alloyed steel axle-mounted brake disk, the temperature of steel disk sharply raises, 1: 1 friction abrasion test stand performance test result according to alloyed steel axle-mounted brake disk and powder metallurgy brake lining friction pair, when the emergency braking initial velocity when 200km/h is above, the hot face temperature of brake disc is more than 300 ℃, therefore, steel disk should have good high-temperature mechanical property and heat-resistant anti-fatigue performance, according to " technical specifications that the JZP01 profile shaft is brake disk mounted " regulation, steel disk should carry out the high-temperature mechanical property test.
6, the technical problem of machining aspect, the alloyed steel axle-mounted brake disk has high intensity and higher hardness after heat treatment, and the technical requirements of product, form and position tolerance, surface roughness etc. all have higher requirements, relation because of special thermal treatment technology, the heat treated cycle is longer, be easy to generate distortion, require to have enough allowances for finish, machining is difficulty very.
