Structural transformation and practice of KKG large cupola

Cupola has many advantages, such as high efficiency, energy saving, continuous melting, good quality of liquid iron and large supply. We have improved the 35t/h cupola, and increased the depth of the furnace cylinder reduces the coke consumption by 14kg/t, the liquid iron temperature by about 30℃, and the erosion rate of the lining is reduced. The method of building slag-separator in layers is adopted to prolong the life of lining and reduce the material consumption. Design and use small slag separator to adjust the composition of liquid iron; Monitor the lining temperature and maintain the lining accordingly. It can meet the requirements of high quality and low cost of current products, and has achieved remarkable results.
