Description

Technical field: [0001] The invention relates to the field of red lead processing, in particular to a red lead oxidation furnace heating device. Background technique: [0002] Currently in the production of red lead, the temperature in the red lead oxidation furnace is as high as 470°C, and the initial temperature of the oxidized red lead powder is also around 470°C. Most of the finished red lead products are packaged in ton or half-ton plastic container bags, which are damaged because they cannot withstand high temperatures, resulting in increased production costs. [0003] The traditional method is to put the oxidized red lead powder in a high-temperature resistant container in advance, and then put it into a packaging bag for storage management after cooling, which extends the process flow and leads to low production efficiency. Moreover, since the production process of red lead is to melt lead ingots, make powder, granulate, calcine and oxidize, etc., these processes ar...

[0003] The traditional method is to put the oxidized red lead powder into a high-temperature-resistant container in advance, and then put it into a packaging bag for storage management after cooling, which extends the process flow and leads to low production efficiency

Moreover, since the production process of red lead is to melt lead ingots, make powder, granulate, calcine and oxidize, etc., these processes are all completed under high temperature conditions in iron containers, and the temperature in the red lead oxidation furnace is as high as 470°C, the initial temperature of the oxidized red lead powder is also around 470°C, the heating effect of the existing red lead heating device is not good, the efficiency is low, and the production is affected
