Q:Why rail interface with?
The scientists measured the temperature of the rails at 1 degrees, and the length of the rails varied by 1.8 microns per metre. If there is no gap in the rail connection, the rail will be extruded, twisted and arched, so that the whole railway will be deformed.
Q:Scrap rail has what use, what enterprise demand on rail?
Demand: renovation and reuse; hardware design; steel smelting furnace.Section 180, bottom width 150, top width of 75The price, of course, depends on the foreigner's offer
Q:What type of rail is the main type used on the railway?
Heavy rail mainly used for 50KG/MRail is divided into two kinds: heavy rail and light rail,Rail specifications are expressed by nominal weight per metre.Heavy rail: rail of a nominal weight greater than 30 kg per meter
Q:Why is the thermit reaction welded to rails instead of welded rails?
Steel contains other added elements, while the thermit reaction produces only iron.
Q:Why does the train not skid on the rails?
But in the actual operation, locomotive could slip, which is mainly due to the change of external conditions, the formula is in good condition to face, if there is oil, cream, water and other impurities on the track, or line quality is not good, may also be part of the locomotive itself result, the adhesion coefficient will decrease, when the locomotive traction motor traction play may be greater than the adhesive force, formed the so-called idle, the locomotive is harmful and must be eliminated quickly. Generally use sand to increase adhesion coefficient, no, then the locomotive will reduce load, reduce traction.
Q:What are the characteristics of a curved track compared with a straight one?
Rail function:Take the wheel load directly and transfer it to the sleeper, guide the wheel of the train; provide the least resistance surface for the wheel roll.In electrified railway or automatic block section, rail has the function of track circuit.Requirements for rails:Sufficient strength, stiffness and surface should have good smoothness and wear resistance. When the wheel passes, the rail will not deform too much, so as to reduce the dynamic impact between wheel and rail.Rail type: expressed by the mass kilogram per meter. The main types of rail in China are 75, 60, 50, 43, four types, and their quality per meter is 74.414, 60.64, 51.514, and 44.653kg, respectively. Rail 60 is widely adopted in the speed increasing main line and the high-speed railway. 75Rail is used on heavy haul lines.
Q:The rails of the high iron welded together as a whole
After laying high speed rail, the technicians will use advanced welding technology to carry out two welding and grinding between the rails. A length of 500 meters, weighing 30 tons of rail welded into an ultra long seamless line, to achieve a track shop in the end. A flexible joint is arranged at the expansion joint, and the expansion space provided with the heating is reserved.
Q:Why are some city railways called light rail? What is heavy rail?
The rail is divided into two kinds of heavy rail and light rail. The rail specification is expressed by the nominal weight per meter.Heavy rail: the nominal weight of more than 30 kg per meter, rail belongs to heavy rail, heavy rail is divided into general rail and crane rail two. General rail means rail laying, dedicated lines, bend and tunnel rails. Among them, the standard track length is 12.50 meters and 25 meters in two, the laying of the curve rail, slightly shorter length, 12.46 meters, 12.42 meters and 24.96 meters, 24.92 meters and other rail, general specification for 38, 43, 45, 50, 60 (kg / m).
Q:How to solve the problem of thermal expansion and cold contraction of railway rail?
The railway line to solve the rail expansion and contraction method is generally used for fastening the way, is the shrapnel into spring fastener fastener (also called spring bar fastener), rail tightly in the sleepers, forcibly will produce thermal expansion and contraction of the energy to digest, but the existence of such a problem is generated when the thermal expansion and contraction energy is greater than the distance unit of sleeper rail adhesion, makes up the phenomenon of rail, rail sleeper unit length twist.
Q:What is the function of a railway joint connection part?
The intermediate connecting parts, also called fasteners, have different combinations according to the different types of sleepers used. The wooden, including ordinary spike and iron plate. The advantage of this kind of fastener is less parts, easy installation, but little effort. In order to improve the performance of wooden, many countries use screw spike or spring instead of ordinary spike spike, or use a variety of different types of fastener on the concrete sleeper has been effective. The concrete sleeper fastening, including anchor bolts, iron plate, fastening piece and an elastic cushion (a) anchor bolt. For fastening fastening parts by anchoring various methods. The use of China on the railway is a sulfur anchor mix of sulphur, sand, cement and wax mixture is melted into colloid, injected into the reserved hole in the sleeper, as the fixed anchor bolt medium, pulling resistance, durability and insulation performance are very good. (b) iron backing plate. The utility model can disperse the vertical pressure of the rail, and after adding the shoulder, the transverse force transmitted by the rail can be partly taken, but because the compressive strength of the concrete sleeper is very large, the utility model can not be arranged in general. (c) fastening parts. There are two types of rigidity and elasticity. Rigid fastening parts mainly for buckle type; elastic fastening parts are spring and bar use plate elastic strip type two. (d) elastic cushion. When the train passes, the utility model can buffer and reduce vibration, and can improve the insulation performance of the concrete sleeper. Rubber backing plate, plastic backing plate, cork rubber backing plate and wood backing plate etc., and rubber backing plate is the best.
