Description

TECHNICAL FIELD

[0001] The utility model relates to the smelting equipment technical field of metallurgical industry more particularly is a copper water jacket with a port. BACKGROUND

[0002] In the metallurgical industry, metallurgical furnace is the key equipment to realize metal smelting. In order to ensure the stability and service life of furnace body and refractory material in high temperature environment, water jacket is usually installed on metallurgical furnace for cooling or protection. At present, the common metallurgical furnace water jacket structure is mainly the flat plate water jacket of side blown furnace. However, the water jacket structure of prior art has many limitations, which is difficult to meet the production demand of modern metallurgical furnace with high efficiency, energy saving and long service life. Specifically, the problems in prior art are as follows: 1. Structural defects of side blown furnace; the flat plate water jacket is usually installed on both sides of metallurgical furnace, and these water jacket parts are provided with spray gun or nozzle mounting hole for air supply or energy supply to the furnace. However, at both ends or arc area of the water jacket, the water jacket and spray gun, nozzle are not installed. This leads to temperature radiation dead angle in the end area of furnace body, which is easy to form temperature uneven layer. This uneven temperature distribution not only makes the production process difficult to control, but also leads to the decline of product quality index, and further affects the overall production efficiency. 2. Insufficient cooling of top blown furnace; the traditional top blown furnace is usually not provided with water jacket, spray gun or nozzle on both sides of furnace wall. This makes the air volume of top blown furnace in the running process large, but the oxygen concentration is low, which cannot effectively utilize energy, and also limits the cooling effect and service life of furnace body. 3. Cooling and strength problem of bottom blown furnace; the tuyere structure of bottom blown furnace mainly consists of steel shell, gun port water jacket and gun port brick. The cooling area of this structure is small, and the strength is insufficient, which leads to short service life of spray gun and gun port brick. Frequent replacement of spray gun and gun port brick not only increases the production cost, but also reduces the operation rate of metallurgical furnace. 4. Limitation of single air supply and energy supply mode; most of the existing metallurgical furnaces adopt single air supply or energy supply mode, which lacks diversity and flexibility. This single energy supply mode cannot meet the demand of different air volume, air pressure and oxygen concentration in complex metallurgical process, which limits the improvement of smelting efficiency.

[0003] Therefore, in view of the existing problems, how to provide a copper water jacket with a port, which can optimize the performance of metallurgical furnace, improve its thermal efficiency, cooling effect and service life, and reduce production cost and improve operation rate at the same time, is a problem that technicians in the field need to solve urgently.
