Regarding water-cooled liningless cupolas, the following points are briefly discussed here. As for the preheated air-supply, the next section will be discussed. Water-cooling method Initially, water-cooled cupolas used water jackets with good cooling effect. However, the explosion accidents caused by the water jacket steel plates escaping into the furnace caused an explosion. This cooling method has been eliminated. . After the blast furnace was able to withstand long-term operations, it was cooled on the outside of the furnace with water. While the large-scale cupolas have been used in various countries, showers have long been used to cool the outer walls of the furnace. Since then, large-scale liningless cupolas cooled in this way have been manufactured and widely used in countries all over the world. The basic characteristic of the cupola furnace is that it does not use refractories lining up from the tuyere and sprays water from outside to cool the furnace body. The small cupola furnace is partially lining-free and linings in pre-tropical refractory masonry, with no lining in the melting zone.
In the early days, the tuyere was cooled by pure water made of pure copper, and it protruded slightly into the furnace. The lining of the furnace below the tuyere is built to prevent the temperature of the molten iron from falling. In the mid-decade, it is recommended to use a pure copper tube wind tuyere, its structure and installation of the figure shows the tuyere protruding from the length of the furnace mouth due to different diameters of the cavity and slightly different. The height and length of the structural installation height and the length of the mouth of the cupola with different capacities are shown in the cupola-coiled cupola tuyere. The wind speed at the tuyere should be higher than that of a traditional cupola, preferably at 70 to ensure that the blast energy can The base of the bottom coke makes the bottom coke produce high temperature and the heat loss can be as small as possible. The structure of the hearth structure of the hearth is in contact with the molten iron and slag. It is made of a refractory material with good corrosion resistance, thermal stability and fire resistance. The main components (mass fraction) are exemplified by the following: The exterior brickwork bricks are filled with graphite-based knotting material between graphite bricks and shell steel.
