Continuous sacrificial anode casting technology

Abstract

The invention belongs to the field of sacrificial anode casting, and particularly relates to a continuous sacrificial anode casting technology. The technology comprises following steps: before-furnace preparing is carried out; base stocks are continuously put in a continuous casting furnace, casting is carried out, and a base stock melt is obtained; when the weight of the base stock melt entering a heat preservation furnace reaches the set value, melt supply is stopped; an alloy element and an aluminum beryllium alloy are added in the base stock melt successively, permanent magnet stirring is carried out, and molten alloy is obtained; standing and sampling are carried out, after it is analyzed that qualification is achieved, the molten alloy is poured into a casting mold, cooling is carried out, and a finished product is obtained. Continuous putting of the base stocks can be achieved, meanwhile, the amount of the base stock melt needed by casting of one sacrificial anode in the heat preservation furnace can be effectively controlled, and therefore continuous production is achieved, and the traditional sacrificial anode casting efficiency is improved; through the manner that the alloy is element is firstly added, and after the alloy element and the base stock melt are melted, the aluminum beryllium alloy is added, crystalline grains are refined, and the produced sacrificial anode is uniform in component and free of cracks.

Description

technical field [0001] The invention relates to a sacrificial anode continuous melting and casting process, which belongs to the field of sacrificial anode melting and casting. Background technique [0002] At present, when traditional sacrificial anodes are smelted, a melting furnace is used to melt the base material required for a sacrificial anode, and then the resulting base material melt flows into the holding furnace to stir and obtain an alloy melt, and finally casts to obtain a sacrificial anode product . But there are following two main problems in traditional craft: [0003] 1. The production efficiency of the sacrificial anode is low, and continuous production cannot be realized; [0004] 2. The sacrificial anode obtained by the traditional process often has defects such as uneven composition and cracks. When it is put into use later, it is prone to the problem of poor cathodic protection performance. Contents of the invention [0005] The technical problem t...
