Crane rail material grade

 


Crane rail material grade  

Crane rail material grades include low carbon steel, high yield strength steel, carbon steel, boron steel, and low alloy steel.

Crane rail is used for carrying heavy objects, which have high bearing capacity. Crane rail is also called crane rail. Its height is low and its head width and waist thickness are large. It is required to check the chemical composition and tensile strength. Used for laying crane and trolley rails.

Crane rail materials are manganese steel, carbon steel, high silicon copper, copper rail, silicon rail, and so on. The railway rail is composed of steel, which can be divided into ordinary manganese-containing steel rail, copper-containing ordinary carbon steel rail, high silicon copper-containing steel rail, copper rail, manganese rail, silicon rail, etc. Most crane rails adopt U71Mn, and most light rails are made of Q235 and 55Q; Most heavy rails are made of 45MN and 71mn

Among the crane rail material grades, U71Mn is the best material. Because adding 2-3% manganese into the steel, the low manganese steel is as brittle as glass. However, if adding > 13% manganese to make high manganese steel, it will become both hard and ductile. Therefore, people use manganese steel to make wear-resistant machine parts, bridges, and crane rails.

What are railway rail fasteners？

What are railway rail fasteners？ Railway rail fasteners Railway rail fasteners are a kind of railway accessories. The parts used to combine rails and sleepers (or other types of under-rail foundations) on the track are also called central joint parts. Its function is to fix the steel rail on the sleeper, maintain the gauge and prevent the longitudinal and lateral movement of the rail relative to the sleeper. The railway rail fastener system is divided into the shrapnel fastener system, gusset fastener system, and elastic strip fastener system. The gusset-type fastener is composed of a gusset plate, a threaded spike, a spring washer, an iron seat, and a buffer pad. The threaded spike is anchored in the reserved hole of the concrete sleeper bearing platform with sulfur cement mortar, and then bolts are used to fasten the buckle. Plate fastened. There are elastic strips I, II, and III types of clip fasteners. Type I elastic strip is composed of ω elastic strip,  screw spike , gauge b...

  What are seamless rails? seamless rails Continuous seamless rails, also known as a welded long rail line, is a line that welds ordinary rails without leaving rail seams. meters or longer. The long rails are laid and fixed on the sleepers within the specified temperature range. There are rail slits at the end of the long rail, and the middle part cannot expand or contract with the temperature rise and fall. Therefore, the middle section of the steel rail will generate a large temperature pressure in summer and a large temperature tension in winter. The large pressure and tensile force in the rail can be calculated according to the annual high and low temperature of the place where the rail is laid. The large pressure on the rail should not cause the rail to buckle, and the large tensile force should not cause the rail to break. The seamless rails line greatly reduces the  rail joints , reduces the impact on the rails when the wheels pass through the joints, is conducive to s...
