Steel Wire Braided Hose Controlled Technology

In order to control cooling after rolling technology to better promote and applied to the production of seamless Steel Wire Braided Hose tube, seamlessSteel Wire Braided Hose tubes for rapid cooling after rolling to get the surface of high strength, high toughness acicular ferrite microstructure and tempering sorbate organizations, significant grain refinement, the overall mechanical properties of Steel Wire Braided Hose greatly improved.
For carbon structural Steel Wire Braided Hose and alloy structural Steel Wire Braided Hose, rolled after the adoption of appropriate rapid cooling process in the dual role of rapid cooling and heat tempered Steel Wire Braided Hose themselves, get surface with high strength, high toughness tempered sorbate, acicular ferrite, kainite and other organizations, while the internal network to reduce the degree of ferrite grain refinement, the overall strength and toughness of Steel Wire Braided Hose and other mechanical while improving performance and, in the case of elongation does not decrease greatly improved toughness, improve the state-rolled low impact toughness. Allow rapid cooling process after rolling thick-walled seamless composite thickness direction of the organization, the overall benefit of improved overall performance.
Cooling the hot-rolled Steel Wire Braided Hose mainly by radiation, conduction and convection in three ways. Among them, the convective heat transfer between the pipe surface and the cooling medium is the main way of cooling. Using a mixture of water and air as a cooling medium, called "mist cooling." When air-cooled, Steel Wire Braided Hose pipe surface heat faster than their thermal conductivity is much slower, more uniform thickness direction of the Steel Wire Braided Hose pipe temperature; when mist cooling, heat pipe surface speed greatly improved, there is a certain temperature gradient near the surface of the Steel Wire Braided Hose pipe thickness direction. Finishing the hot-rolled seamless process reaches room temperature in about 950, depending on the cooling conditions, the austenite decomposition product of different tissue types.
