Abstract

The invention discloses a metal workpiece surface reduction device and method. The device comprises an inlet section, a spare part section furnace body, a heating section furnace body, a cooling section furnace body and an outlet section. The inlet section is installed above the spare part section furnace body in a sealed mode. The spare part section furnace body, the heating section furnace body, the cooling section furnace body and the outlet section are sequentially connected in a sealed mode from right to left. Heating units of the heating section furnace body are evenly distributed in a furnace wall. A lifting connection piece device is arranged at the position, corresponding to the inlet section, of an inner cavity of the spare part section furnace body. Roll gangs locate in the same horizontal level are arranged in the spare part section furnace body, the heating section furnace body, the cooling section furnace body and the outlet section. According to the metal workpiece surface reduction device and method, continuous production can be achieved, working efficiency is ensured, the labor intensity of workers is reduced, nitrogen is adopted for reducing an oxidation layer on the surface of a metal workpiece, the metal workpiece with the flat surface can be obtained, the surrounding environment is effectively protected, secondary loss of metal is avoided, and the metal utilization rate is improved.

Description

technical field [0001] The invention relates to the field of ashtrays, in particular to a device and method for restoring the surface of metal workpieces. Background technique [0002] Oxidation of metal is a process in which the carbon dioxide, water and oxygen in the furnace gas or air react, and the scale is the product of the high temperature of the metal surface. The oxidation of the metal is very slow when the temperature is lower than 200 ° C. When the temperature increases to 700 ° C to The oxidation rate starts to accelerate at 850°C, and increases sharply when the temperature rises to 1000°C. [0003] The existence of oxide skin on the metal surface will cause metal loss, and at the same time accelerate the corrosion rate of the metal matrix, thereby reducing the service life of the metal. There are two ways to remove the scale on the metal surface, one is pickling and the other is mechanical treatment. Pickling is the use of acidic solution to remove scale and r...
