45 days on average from the date of shoeing the horseshoe replacement is not due to the product wear but to uneven horse hoof growth it has been determined from the chart above that the alloys that may be used for the manufacture of durable horseshoes would be the ones containing at least copper cu zinc zn and aluminum al with the respective tolerances listed in the table below the continuous casting process is used to obtain copper alloy bars in which the operators weight the various quantities of metals required for the alloy according to the composition determined in this invention once the raw materials have been dosed in the drums they are taken to lifting platforms that will lift the dosed material to the corresponding melting furnace the material coming from the dosing area is poured into the melting furnaces of each line before pouring the metal from the melting furnace into the holding furnace alloy samples are taken these are analyzed at the chemistry laboratory using the emission spectrometry method and the atomic absorption spectrometry method which ensure compliance with the specifications with regard to the alloy chemical composition when the metal is molten and it has been confirmed that the alloy is within the established parameters the melting furnace is tilted and the molten metal is poured into the holding furnace through transfer channels the continuous casting of the material is produced from this furnace.
