With the hydraulic support of the large-scale, lightweight, hydraulic steel intensity level is also gradually improved, by 50kg, 60kg, 110kg to 100kg, even 120kg grade, and high level steel consumption is increasing.
In order to adapt to the needs of the market, Wugang company from Germany LOI company introduced a complete set of thick plate quenching and tempering line, using a non-oxidizing roller test bottom heating furnace, roller quenching machine, the main product specifications for the thickness of 8-120mm, 1600-4000mm, length 4000-16000mm width.
Q690D has good welding performance of steel shot blasting; before quenching, quenching furnace radiant tube heating, no oxidation atmosphere control and other measures, so that the steel has good surface quality; quenching machine for roller design, the partitioning of water cooling, ensure the mechanical function average, and has a good shape.
Q690D: steel material a, also known as grade. Hydraulic support with steel plate.
Q: submission in 690 or so,
D: represent shock temperature: 20 degree.
