Mild steel wire manufacturing device eliminates the surface oxide

摘要

the idea is that the flexible line in order to make the taste more than 600 degrees, heating treatment, to the room temperature, and after the surface oxidation film, plating process for pickling steel surface oxidation and acid can be ubb38uc81cub85c pollution. the invention is a liquefied petroleum gas is vaporized to one adiabatic expansion, according to the heat absorbing effect, so that the sealed tube to pass into the gas in the vacuum maintenance is to prevent the oxidation, and cooling at the same time on the acid will not be.. the workshop to improve the flexible line, and the mass production is possible.
