Abstract
Способ термообработки стальной проволоки включает в себя известные этапы разматывания стальной проволоки со скоростью подачи проволоки, направления стальной проволоки через секцию нагрева, содержащую одну или несколько индукционных катушек, охлаждения и наматывания стальной проволоки на барабан. В частности, в отношении указанного способа следует отметить, что в секцию нагрева нагнетается защитный газ с расходом, который зависит от скорости проволоки. Авторы изобретения установили, что расход защитного газа должен уменьшаться с увеличением скорости. Защитный газ не нагнетается в секцию нагрева, когда линия движется с рабочей скоростью. Это ведет к уменьшенному расходу защитного газа. При необходимости замены приемного и размоточного барабанов, и когда линия должна двигаться с низкой скоростью, расход защитного газа увеличивается. Настоящее изобретение позволяет регулировать тип и уровень оксидов, образующихся на проволоке. Изобретение также относится к устройству, внедряющему способ, в котором расход защитного газа зависит от скорости проволоки, движущейся через систему управления.The method for heat treating a steel wire includes the known steps of unwinding the steel wire at a wire feed speed, guiding the steel wire through a heating section containing one or more induction coils, cooling, and winding the steel wire onto a reel. In particular, with regard to this method, it should be noted that the shielding gas is injected into the heating section at a rate that depends on the wire speed. The inventors have found that the shielding gas flow rate should decrease with increasing speed. No shielding gas is injected into the heating section when the line is moving at operating speed. This leads to a reduced consumption of shielding gas. If it is necessary to replace the take-up and unwinding drums, and when the line must move at a low speed, the consumption of shielding gas increases. The present invention makes it possible to control the type and level of oxides formed on the wire. The invention also relates to a device implementing a method in which the flow rate of the shielding gas is dependent on the speed of the wire moving through the control system.
