Battery cast welded device, method and storage medium.
Background technology
During the manufacturing of lead-acid battery, battery grid casting (following grid casting), battery electrode group confluxes
(hereinafter referred to as battery cast welded) connection of row's cast welding is the critical process during storage battery production, is directly connected to the production of battery
Quality, efficiency, production cost, environmental protection etc..In the process, the heating to mould with injecting lead liquid for especially in a mold
Two important processing steps.
The main following several ways of heating to cast welding bottom die and plate grid die at present, first, when battery cast welded that bed die is complete
It is complete to immerse in lead liquid (hereinafter referred to as immersion), heated by heat transfer.In the battery cast welded cooling because being contemplated that mould,
Therefore die quality is bigger, so causes the heat that mould is taken away when long heat time, cooling more, high energy consumption.Second of side
Formula is to use Frequency Induction Heating, and which is complicated, cost of equipment is high, and sensing heating easily produce heating it is uneven

There are many defects in the metal liquid non-quantitation mode of leaching, both of which, be that the bottleneck of the current lead-acid battery production of puzzlement is asked
Topic.High temperature metal liquid quantitatively has various ways, but is all based on mould greatly and quantifies.It is different in battery industry high-temp liquid lead
In other high temperature metal liquids, lead liquid surface is oxidized easily to form lead skim, and lead skim has a great influence to cast welding quality, such as empty
Weldering, sealing-off etc..Present most of cast weldings reintroduce liquid level mainly using being that cast welded mold is sunk in lead liquid, but on cast welded mold
Lead liquid the lead skim band on lead liquid surface can be got up, slag can be scraped using slag-scraper so most of, but this is confined to lead liquid
The amount of surface lead skim, so the lead skim of lead pan must drag for every several moulds, in order to ensure quality requirement, often mould all must for many producers
It must drag for once.So cause in whole production process that lead skim amount is big, considerably increase production cost.
