Wide lead ingot water spray cooling system and temperature control method

The invention relates to lead ingot production equipment, particularly provides a wet lead ingot water spray cooling system and a temperature control method, and aims to solve the problem of poor lead ingot cooling effect in the prior art. In order to achieve the purpose, the wet lead ingot water spray cooling system comprises a conveying device with a plurality of stations and a spray cooling unit, the conveying device is suitable for bearing a plurality of lead ingot molds; the plurality of spray cooling units are arranged on one side of the conveying device and correspond to a plurality of stations on the conveying device; and the spray flow of the plurality of spray cooling units is gradually reduced along the running direction of the conveying device. According to the scheme, when the ingot casting machine is used for controlling the ingot casting temperature, temperature grading control and decreasing control from high temperature to low temperature are adopted, water flow is controlled according to a t
