Abstract
The invention discloses a method for preparing a cathode used in refining of lead bullion and belongs to the field of non-ferrous metals. The method comprises the following steps: (1) preparing a material for casting a cathode; (2) casting the cathode; and (3) finishing the cathode. By the method, the problems of high production cost and low production efficiency caused by the unreasonable composition and size of the cathode in the existing electrolytic refining of lead bullion are solved and the method has the advantages of being simple in process, low in cost and easy to process.
Description
Technical field
The invention belongs to non-ferrous metal field, more particularly, relate to a kind of manufacture method of electrode used therein when utilizing performing electrolytic refining on lead bullion.
Background technology
Lead is widely used industrial at present, especially maximum at electrical industry department consumption, is mainly used to manufacture store battery, various cable protection skin, fuse wire etc.Stereotype and lead pipe are often done to smelt and chemical industry equipment antiseptic acidproof lining, corrosion cap, plumbous protective layer and the protective shield being also used as nuclear industry and X-ray.Plumbous compound is used for pigment industry, glass industry, petroleum industry and medical department etc.Plumbous in the process of processing refinement, utilize the method for electrolysis to realize plumbous refining, not only make plumbous purity be improved, also achieve the recycling of precious metal.And be utilize the negative electrode in electrode to reach the object of Adsorption of Lead in electrolytic process, the manufacture therefore for negative electrode is particularly crucial.
Summary of the invention
For existing utilize performing electrolytic refining on lead bullion time, because of composition and the off size reason of negative electrode, and cause the problem that production cost is high, production efficiency is low, the invention provides a kind of manufacture method of refining of lead bullion negative electrode, by composition and the size thereof of reasonable preparation negative electrode, reach and enhance productivity, reduce the object of production cost.
For solving the problem, the present invention adopts following technical scheme.
A manufacture method for refining of lead bullion negative electrode, comprises the following steps:
(1) preparation of negative electrode casting material:
In negative electrode casting material, the mass percent of each chemical composition is: Pb: >=99.994%, Cu :≤0.001%, Ag :≤0.0005%, Bi :≤0.003%;
(2) casting of negative electrode:
Automatic continuous slab machine is utilized to complete the casting of negative electrode;
(3) precision work of negative electrode:
Utilize lathe to complete the precision work of negative electrode, make its length be 900-1200mm, width is 650-780mm, and thickness is 1-2mm.
Preferably, in described step (3), the length of negative electrode is 1100mm, and width is 700mm, and thickness is 1.5mm.
Compared to prior art, beneficial effect of the present invention is:
(1) the present invention passes through composition and the size thereof of reasonable preparation negative electrode, improves production efficiency, reduces production cost.
(2) the inventive method is simple, handling ease.
Embodiment
Describe the present invention below in conjunction with embodiment.
