Abstract

The invention provides an environment-protecting nickel-iron-chromium electrothermal alloy pickling treatment device. The environment-protecting nickel-iron-chromium electrothermal alloy pickling treatment device comprises a pickling tank, wherein the bottom wall of the pickling tank is connected with a first motor, and the output end of the first motor is connected with a rotating shaft; the end,far away from the first motor, of the rotating shaft penetrates through the pickling tank and is connected with a first gear, the top of the first gear is connected with a filter screen cylinder, anda metal workpiece is placed in the filter screen cylinder; a rack ring is connected to the inner wall of the pickling tank, and a second gear is connected between the rack ring and the first gear ina meshed mode; and a conveying pipe is connected to the outer wall of the second gear, discharging holes which are evenly distributed are dug in the outer wall of the conveying pipe, and a rotating rod is rotationally connected into the second gear through a bearing. According to the environment-protecting nickel-iron-chromium electrothermal alloy pickling treatment device, hydrochloric acid is added into the pickling tank, so that the concentration of a pickling solution in the pickling tank is ensured to be sufficient, then the pickling effect and the pickling efficiency of the alloy workpiece are ensured, and the percent of pass of a finished product is ensured.

Description

technical field [0001] The invention relates to the technical field of pickling devices for processing alloys, in particular to an environment-friendly nickel-iron-chromium electrothermal alloy pickling treatment device. Background technique [0002] At present, there are two main types of electrothermal alloys: one is iron-chromium-aluminum alloy with ferrite structure; the other is nickel-chromium alloy with austenite structure. These two types of alloys have different performances due to their different structures. The same, but as electric heating materials, they all have more advantages, so they are produced in large quantities and widely used in various countries. There are many processing procedures for electric heating alloys, such as wire drawing, hot rolling and cold rolling, and usually need to be adjusted after forming. For pickling, hydrochloric acid pickling technology is more common at present. [0003] The method of using an acid solution to remove scale and...
