Seamless Steel Tube Thermal Spraying Technology

Method of organizing steel sprays can be around divided into two categories: bodily substance and mechanical method. Physical strategy is all about mechanical crushing strategy and steel melt atomization. The former one employs the mechanical running, vortex running, crushing and centrifugal ventilation crushed and other technologies.

The next one is divided into common atomization and quick solidification atomization method. Usually the one applying quick solidification right from the steel melt atomized steel powder in the powder metallurgy and materials science has attracted much attention. Dual atomization is the key approach to today's industrial manufacturing of steel powder.

The high-pressure water atomization and high-pressure gasoline atomization strategy applying large force water and large force gasoline since the atomizing press to separate the continuous thin stream of molten steel,The progress of steel powder engineering Articles they are the main strategy for the manufacturing of steel powder. The atomization system including the formation of water thin coating, the thin coating of damaged steel flow of silk and steel flow bond contraction of the three phases of the micro-droplets. High-pressure gasoline atomization of 50-100¼michael length steel powder, high-pressure water atomized powder chemical measurement between 75-200¼michael; gasoline atomized powder for easy circular chilling charge of approximately 102-103 ° C / s, water atomization powder usually posseses an abnormal form and surface, the chilling charge of 102-104 / s. High-pressure gasoline atomization and water atomization is commonly found in large-tonnage manufacturing of aluminum, instrument material, tremendous alloys, bronze powder(FCu 663), metal, container and low-alloy powder.

The rapidly rotating glass strategy also referred to as the rotating water law. Press to the rotating glass quenching moderate (which may be aqueous answers, hydrocarbons, cryogenic liquids, etc.), steel flow is damaged under the force of the argon, water steel, quench, under the centrifugal force through quick quenching press to reach the turning and ultimately have the powder. Analysis showed that increasing the speed of the rotating glass, reduce the water steel nozzle measurement, and increase the superheat of the water steel can be sophisticated powder measurement; raise the gasoline atomization technology procedure force may reduce the splashing of the water steel at first glance of quenching moderate, and then improve powder healing rate. The molten steel first gasoline atomization, centrifugal atomization and distress atomization, and then to the rotating glass quenching moderate, which may be prevented crucible nozzle blocking and corrosion, but also increase the atomization efficiency.
