Embodiment Construction

[0036] combine Figure 1-12 The manufacturing method of the large-scale prebaked anode electrolyzer shell comprises the following steps:

[0037] A. Material purchase acceptance; the materials used for the tank shell must meet the requirements of the design drawings and technical regulations. The purchased materials must have a material certificate, and all technical indicators must meet the corresponding national standards. Retest the chemical composition and mechanical properties of suspected materials, and those that do not meet the requirements must not be put into use. Check the appearance of the material before use, and those with defects such as cracks, shrinkage cavities, air bubbles, slag inclusions, and wrinkled skin must not be put into use. The material needs to be corrected when the following conditions exist: when the unevenness of the strip material is ≥ 1 / 1000, and the undulation of the profile is ≥ 1 / 1000. At the same time, in the whole process of making the...

Abstract

The invention relates to the technical field of large electrolytic cell machining, and provides a large prebaked anode electrolytic cell shell manufacturing method capable of effectively relieving thewelding deformation. The large prebaked anode electrolytic cell shell manufacturing method comprises the steps of: (A) material stock acceptance check; (B) end plate manufacturing; (C) side plate manufacturing; (D) base plate manufacturing; (E) delivery transportation; and (F) field assembly. Through control of the welding mode and the welding sequence, the influence by the welding deformation iseffectively reduced, the once pass percent in the electrolytic cell shell machining process is greatly increased, the construction period is shortened, and the quality of electrolytic cell shells isimproved.

Description

technical field [0001] The invention relates to the technical field of large-scale electrolytic cell processing, in particular to a manufacturing method for a large-scale prebaked anode electrolytic cell shell. Background technique [0002] Due to the characteristics of low density, high strength, good electrical and thermal conductivity, good corrosion resistance, and easy processing, aluminum and aluminum alloys are widely used in aviation, aerospace, transportation, power systems, building materials, daily necessities and other fields, while aluminum The main equipment for the production of electrolytic aluminum is the aluminum electrolytic cell. Self-baked anode electrolyzers have been eliminated by the country due to their high energy consumption, and now they are replaced without exception by large-scale prebaked anode electrolyzers, generally with 180KA, 230KA, 240KA, 320KA, 350KA, 420KA and other specifications. type. As the cell type grows from small to large, the...
