Cadmium reduction furnace and manufacturing technique thereof

Abstract

The invention discloses a cadmium reduction furnace and a manufacturing technique thereof, and relates to the technical field of chemical equipment. The cadmium reduction furnace comprises a furnace body. A plurality of carbon tubes are arranged in the furnace body at intervals. The cadmium reduction furnace further comprises a plurality of reinforcing plates. The reinforcing plates include a plurality of first reinforcing plate, a plurality of second reinforcing plates and a plurality of third reinforcing plates. The first reinforcing plates are connected with the carbon tubes on the same horizontal plane correspondingly. The second reinforcing plates are connected with the carbon tubes on the same vertical plane correspondingly. The third reinforcing plates are arranged on the bottom wall of the furnace body. The manufacturing technique of the cadmium reduction furnace comprises the following steps that (1) the reinforcing plates are welded to the bottom wall of the furnace body; (2)the carbon tubes on the same vertical plane are welded through the corresponding reinforcing plates separately; and (3) the carbon tubes on the same horizontal plane are welded through the corresponding reinforcing plates separately. According to the cadmium reduction furnace and the manufacturing technique thereof, a reinforcing structure is additionally arranged in the furnace, so that the welding quality is improved, and the service life of the cadmium reduction furnace is prolonged.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a cadmium reduction furnace and a manufacturing process thereof. Background technique [0002] The original cadmium reduction furnace was fabricated by welding G20 boiler steel plates. Because the high-temperature resistance temperature of the steel in the scheme does not reach the actual temperature that needs to be raised, the internal reinforcement structure of the furnace is not rigorous, and the cadmium solution has a certain degree of corrosion, so the bottom of the furnace is easily deformed during use, and the weld seam or steel plate is corroded. It is easy to crack and leak, and the carbon rod tube at the bottom is easy to burn out. Generally, a cadmium reduction furnace can only be used for 3 months before it is scrapped. According to the analysis of the staff, there are mainly the following reasons: (1) The temperature change of the furnace (2) There is no...

Because the high-temperature resistance temperature of the steel in the scheme does not reach the actual temperature that needs to be raised, the internal reinforcement structure of the furnace is not rigorous, and the cadmium solution has a certain degree of corrosion, so the bottom of the furnace is easily deformed during use, and the weld seam or steel plate is corroded. It is easy to crack and leak, and the carbon rod tube at the bottom is easy to burn out. Generally, a cadmium reduction furnace can only be used for 3 months before it is scrapped. According to the analysis of the staff, there are mainly the following reasons: (1) The temperature change of the furnace (2) There is no reinforced structure inside the furnace, and when the temperature changes greatly, the furnace shell is easily distorted and deformed. Pulling cracked welds and breaking carbon rods; (3) The quality of the welds is not up to the requirements, and the welding quality needs to be improved
