するという不都合を有している。Conventionally, as a method for continuously manufacturing lead-based alloy strips or plates with a compact solidified structure, molten metal is solidified on the surface of a water-cooled rotating drum, and the solidified layer is peeled off to produce strips or plates. The most widely known were the DM method, which produced slabs, and the rolling method, which produced slabs by hot or cold rolling, but the DM method was susceptible to corrosion, and the rolling method However, there were disadvantages in that the corrosion rate was high due to stress corrosion, and the processing cost and equipment cost of the rolling pool was high. In order to solve this problem, a method is known in which molten metal is injected between a pair of rolls, cooled on the outer peripheral surface of the rolls to form a solidified phase, and then continuously rolled. The maximum effective width t of the sound strip or plate obtained by trimming the ends of the strip or plate produced in 1-manufacturing is smaller than the width of the nozzle outlet. This has the disadvantage that laterally diagonal defects such as missing portions of material, cracks, and cracks continuously occur at the edges of the strips or plates.

する。The present invention aims to provide a continuous rolling manufacturing method for a solidified base alloy having a compact solidified structure, which does not have such disadvantages and can continuously produce products with uniform quality and stable performance with high efficiency. 1. As a hypothetical, the solidified structure has a compact form. Molten lead-based alloy is injected into the gap between a pair of rolls, and it is cooled on the outer circumferential surface of the rolls to produce a continuous solidified phase. In the method of producing a strip or sheet metal by rolling, the maximum effective width and thickness of the produced strip or plate are t and t, respectively, and the width and height of the nozzle outlet are L1T, respectively. When T/l is 2 to 6
It is characterized in that t/L is 2 to 60 at a value of 0.
