Description
Technical field
The present invention relates to railway equipment field, a kind of railway high speed track switch, more specifically
Say it is that a kind of railway high speed track switch melts the casting material compound slider bed platen of reason.
Background technology
Slider bed platen is the vitals of railway high speed track switch, is carrying point tongue and high speed row
The security platform of car, slider bed platen direct relation high-speed switch and the utilization of bullet train and operation
Safety.At present, high-speed switch slider bed platen design material is ZG230-45, this kind of slider bed platform
Plate proves to have the disadvantage in that through practice
1, strength character is relatively low, wear no resistance, and the work surface of carrying tongue easily occurs that pressure mill is recessed
Groove；
2, the higher 0.23-0.30 of coefficient of friction, after corrosion, coefficient of friction increases further, causes
Switch convert resistance is bigger；
3, the upper rust of corrosion resistance difference；
4, frequent oiling and polishing are needed；
5, the long workload of curing time is big, and maintenance cost is higher；
6, there is the hidden danger of generation personal safety accident.
For ensureing the application safety of track switch, railway interests of various countries has put into substantial amounts of fund, to height
Speed track switch slider bed platen conducts in-depth research, and its main purpose is:
1, the strength character of slider bed platen, enough anti-wear performances and shock resistance are strengthened,
Eliminate pressure mill groove；
2, ensure the enough hardness of slider bed platen work surface, reduce coefficient of friction, reduce track switch
Conversion resistance force；
3, the corrosion resistance of slider bed platen is improved, it is ensured that in the phase, do not limit rust and tool under arms
Standby good utilization performance；
4, reduce the maintenance time to slider bed platen, reduce maintenance cost；
5, eliminate safe hidden trouble, it is ensured that traffic safety.
Summary of the invention
In order to solve above-mentioned technical problem, overcome the deficiencies in the prior art, it is an object of the invention to
The railway high speed track switch providing a kind of function admirable, cost performance high melts the casting material compound slider bed platform of reason
Plate, this compound slider bed platen not only has good obdurability, but also has excellent combining
Close technical performance.
The technical solution adopted for the present invention to solve the technical problems is:
The railway high speed track switch compound slider bed platen that a kind of hot melt combines, slider bed platen is arranged on
On base plate, described slider bed platen arranging tongue or core rail, described slider bed platen is upper and lower two
Rotating fields is composited, and described lower floor is base material, and described upper strata is for covering material；Described base material is
Q235 steel plate, it is characterised in that: covering material material composition by mass fraction ratio is:
C0.05-0.06%；Cr13.8-14.2%；Si0.42-0.45%；Mo0.68-0.73；Mn1.0-1.1%, remaining
Amount is Fe；Technological process includes: base material covers the equal 1500-1600 degree Celsius of smelting of material makes molten steel,
Then pouring in mould and cover material, material to be covered is cooled to 1100 degrees Celsius, then pours in mould
Base material, is cooled to room temperature, is again heated to 900 degrees Celsius, forging molding.
Described slider bed platen gross thickness >=40mm, base material thickness >=cover material thickness.
Described slider bed platen interface shear strength >=245MPa.
Described slider bed platen surface hardness HB >=280.
Described slider bed platen surface coefficient of friction≤0.23.
The invention have the advantage that
1, advanced technology, function admirable, cost performance are high, reduce manufacturing cost 5-10%；
2, high-wear resistance is 3-5 times of ZG230-45, eliminates pressure mill groove；
3, good obdurability does not ftractures, excellent shock resistance and welding performance；
4, coefficient of friction low≤0.23, switch convert resistance is little, and switch point housing is good；
5, good corrosion resistance is difficult to rust, lacks oiling or exempts from oiling；
6, good environmental adaptability, few maintenance or non-maintaining；
7, maintenance 35% is reduced；
8, the hidden danger of initiation stranger's body security incident is eliminated；
9, use performance safety reliable and stable, extend service life, it is ensured that train operating safety
Steadily.
10, by expanding with heat and contract with cold the principle different with material melting point, base material is made with to cover material firm
Combine.
Accompanying drawing explanation
Fig. 1 is to arrange tongue structural representation on slider bed platen；
In figure, 1 is rail, and 2 is tongue, and 3 cover material, and 4 is base material, and 5 is base plate, and 6 are
Core rail, 7 is boss.
Detailed description of the invention
Illustrate the present invention below in conjunction with the accompanying drawings, as it is shown in figure 1, slider bed platen is arranged on the end
On plate 5, described slider bed platen arranges tongue 2 or core rail 6, described slider bed platen be upper,
Lower double-layer structure is composited, and described lower floor is base material 4, and described upper strata is for covering material 3.
Covering material material composition by mass fraction ratio is:
