Background

The P-S converter is an important equipment for blister copper refining. Through secondary oxidation reactions in the slag-making and copper-making stages, Fe and S in the copper matte liquid are removed to form blister copper.

During the two processes of blowing, the reactions that occur are almost all exothermic reactions, which will release a large amount of heat. Therefore, the temperature of the outer wall of the furnace body is sometimes too high. In addition, the gas and copper matte liquid (as well as the white matte formed later) entering the furnace from the tuyere will scour the refractory materials on the inner wall of the furnace. The temperature of some refractory materials lost or missing parts will be higher, sometimes reaching more than 400 degrees. At the same time, during the blowing process, due to the characteristics of pyrometallurgy, there will be splashes in the blowing process that will adhere to the water jacket and fall behind the furnace after cooling. In order to avoid the damage to the tuyere by falling pieces, a 20mm thick steel plate is added to the center area of ​​the tuyere to protect the tuyere from large pieces. The newly added protective plate will affect the temperature measurement of the furnace body. The protective plate must be modified to measure the corresponding outer wall of the furnace. In addition, the tuyere hose will also block the furnace wall, but the outer wall temperature can be measured through the gap between the hoses.

Product Description

HIRDA-PS P-S converter infrared thermal imaging intelligent monitoring system is a system specially used for temperature monitoring of high-temperature metal smelting furnaces. The system consists of a high-temperature infrared thermal imaging thermometer, an electric control box, an algorithm server, and client management software. It centrally monitors and manages the equipment on the operation site, and realizes the collection, analysis, high-temperature point positioning, automatic alarm and other functions of the P-S converter wall temperature through a digital transmission network.
