【発明の名称】鉛蓄電池用格子体の製造方法
Document Type and Number:
Japanese Patent JP2794745
Kind Code:
B2
Abstract:
PURPOSE:To safely, surely and inexpensively produce the defectless grid body for lead storage batteries by adding a mixture contg. lead selenide, etc., formed on the surface of a molten metal mixture composed of lead and selenium and casting the grid body while holding the mixture on the surface of the molten metal. CONSTITUTION:The lead or lead alloy and the selenium alone or the selenide are mixed ana melted. The mixture consisting of the lead selenide, lead oxide, metal lead, etc., formed on the surface of the molten metal at this time is charged into water and is ground and crushed. This mixture is then added to the lead alloy consisting of a lead/antimony alloy for casting the grid. The mixture is so floated on the surface of the above mentioned molten lead alloy so as to cover the entire surface and is held for a required period of time. The required amt. of the selenium is thereby incorporated into the above- mentioned lead alloy without generating harmful gases. The grid body for lead storage batteries is cast by using this molten metal without generating cracks, etc.
