Luo Jian, as a professional road roller manufacturing company in the industry, did not stop at the current results. Instead, it developed the high-speed rail roller LSS2502 through in-depth research on the high-speed rail market. The LSS2502 roller developed this time, and the vibration system was opened by the past. The system was upgraded to a closed system, and the stability and durability of the product performance were greatly improved. At the same time, the cab was integrated with a soft bag, and functions such as sound insulation, noise reduction, and sealing and dust prevention were significantly improved, effectively improving the operator's performance. working environment.
BRIGHT STEEL BAR
Bright steel bar is carbon or alloy steel bar with shining bright surface which is improved by cold drawing, peeling, turning, grinding and polishing over hot rolled black surface bars. By cold drawing, the steel bar yield strength and tensile strength will be improved. By peeling and turning, the surface imperfections will be removed. By grinding, the diameter tolerance will be more precision. By polishing, the surface will be much more shining.
Except the shining bright surface, comparing with the hot rolled black surface bars, the bright steel bars has better surface roughness, better roundness, straightness, more precision size tolerance etc.
Heat treatment such as annealing, normalizing, quenching and tempering will be done before do cold finishing on the hot rolled bar to get bright steel bar, in such condition, the steel bright bar will get most suitable mechanical properties to meet different application requirement.
The advantages of steel bright bars we supply:
1) Big stocks of hot rolled round bars or wire rods as raw materials
2) Heat treating furnaces to adjust the mechanical properties
3) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.
4) Multiple packages to avoid broken packages and anti-rusty

Yituo (Luoyang) Construction Machinery Co., Ltd. (hereinafter referred to as Luojian) super heavy-duty compaction machine “High-speed Rail Wang†was specially developed for the construction of high-speed rail projects. It was born in early 2009 and fully caters to the fast-growing high-speed rail market. The need for high-speed rail rapid construction. At the domestic high-speed rail construction sites, Shiwu High-Speed ​​Rail and Beijing-Shanghai High-Speed ​​Rail have all left the footsteps of Luo Jian’s “High Speed ​​Rail Kingâ€.
