Increasing the descaling pressure can improve the descaling effect, now the descaling pressure can reach 18-22MPa, or even higher.
At the beginning of high-pressure water descaling, piston pumps were used, with low pump pressure, small flow rate and poor descaling effect, now more stable piston pumps and centrifugal pumps are used.
From the furnace billet scale-removal to the rolling process scale-removal; from the mill before scale-removal to the mill before and after scale-removal; from a single set of pipe scale-removal to multiple set of pipe scale-removal; from the upper set of pipe fixed to the thickness of the billet with the moving adjustment of scale-removal.
High-pressure water descaling nozzle material from the initial ordinary carbon steel to stainless steel, and then to wear-resistant carbide, service life continues to improve; structure from ordinary thread fixed to positioning key slot fixed, with filters, flow stabilizer, anti-clogging, so that the water flow is more concentrated, improve the striking force.
The angle, number and spacing of the nozzles on the scale-removal collector and the online installation height of the collector directly affect the scale-removal effect of the system.
In order to ensure the safe and stable operation of the system, the high-pressure water descaling system and related equipment are equipped with various detection components, which are automatically controlled through PLC interlocks and networked with the steel rolling line system to achieve remote monitoring and integrated operation.
The use of hydraulic coupling and frequency conversion can save energy and keep the system stable operation.
