JPS5853158A - Working of lead-base alloy member for storage battery - Google Patents

Abstract

PURPOSE:To realize working of a lead-base alloy member which gives the member and increased mechanical strength by extruding the member with a high temperature, and immersing the hot extruded member into a refrigerant, being followed by subjecting the member to heat treatment. CONSTITUTION:A molten bath 1 heated to around 370 deg.C and consisting of, for example, Pb, 0.1% Ca and 2% Sn is contained in a metal formation case 3 the outer surface of which is surrounded by a heater 2. The molten bath 1 is extruded with a given presure by means of an extruder 4 or the like, from a formation opening 5 which is provided in the bottom of the case 3 and provided with a formation die, so that a thin plate-like body which has a given shape, a thickness of around 0.5mm. and a high temperature is formed when the bath 1 passes through the opening 5. Thus formed thin plate-like body is immediately immersed into an ordinary-temperature refrigerant 6 such as water or oil which is provided right under it so as to make it to be cooled rapidly, thus a belt-like thin plate with 0.5mm. thickness is obtained. After that, thus, obtained thin plate 7 is subjected to heat treatment at 125 deg.C by being made to pass inside a heating furnace 8 such as an electric heater, thereby completing work treatment of the lead-base alloy member.

- As-8n alloy, Pb-0a-8a alloy, and other binary or ternary alloy caps, clad type, paste type, etc. electrode plate substrates for storage batteries, pole layers, connection rods, etc. Although it is used as a molded product, the manufacturing method depends on the structure or the high cost. It is made by extrusion, molding into plates, wires, rods, etc., but has relatively low mechanical strength. In particular, there is a strong demand for the electrode plates of maintenance-free storage batteries to be as thin and lightweight as possible, and it is desirable to focus on this point and increase mechanical strength.

ようにしてもよい。In the above example, the lead-based alloy is extruded from a molten metal.
It may be heated to a semi-solidified state in a high place that can be extruded, and this may be extruded.Also, instead of the plate-shaped molding described above, it may be formed into a rod-shaped, linear, or pellet-shaped shape depending on the purpose. It can be formed into any shape, and arbitrary processing such as pressure molding, cutting, etc. may be performed between the refrigerant treatment and the heat treatment.

~1.1 times, but when this is subjected to the same heat treatment tm, it is 1!
On the contrary, the yield stress remains the same or less.
Heat treatment was not effective in conventional rolling methods. As another example, 2*8b-0,11! A lead-based alloy consisting of As and Pb as a raw material was heated and melted at about 310°C, extruded into a shape of T41, immersed in water and cooled to obtain ml14 with a diameter of 0.6 days. Heat treatment was carried out at -50 to 70°C. When the yield strength If1 of the wire rods before and after the heat treatment was examined through a tensile test, the strength of the wire rods treated with the heat treatment was 1.2 to 1.8 times higher than that of the wire rods without the heat treatment.・Furthermore, because it is Hiro, it is not cooled in water, and the same thickness O by the rolling method and the same lead alloy composition 41IF
No increase in yield strength was observed even when the same heat treatment was applied to Sample No. 4.
