Description

本発明はこのような知見に基づきなされたもので、その特徴とするところは、炉高方向で炉下部側から順に朝顔部、切立部およびシャフト部を備え、且つ炉下端側に羽口を備えたシャフト炉型冶金炉の炉高方向において、熱負荷が小さい炉上部・中部領域(A)には鋳鉄製ステーブを配置し、それよりも下方の熱負荷の大きい炉下部領域(B)及び炉最下部領域(C)には銅または銅合金製ステーブを配置したステーブ配置構造であって、前記炉下部領域(B)が、朝顔部の上部領域、切立部の全部領域およびシャフト部の下部領域であり、前記炉最下部領域(C)が、羽口上方における朝顔部の下部領域であることを特徴とするシャフト炉型冶金炉のステーブ配置構造である。 The present invention has been made on the basis of such knowledge, and is characterized by a bosh section, a cutting section and a shaft section in order from the furnace lower side in the furnace height direction, and a tuyere at the furnace lower end side. In the furnace height direction of the shaft furnace type metallurgical furnace, cast iron staves are placed in the upper and middle areas (A) where the heat load is small, and the lower furnace area (B) and the furnace where the heat load is larger below it. The lowermost region (C) is a stave arrangement structure in which a copper or copper alloy stave is disposed, wherein the furnace lower region (B) is an upper region of a bosh portion, an entire region of a cut portion, and a lower region of a shaft portion. Wherein the lowermost region (C) of the furnace is a lower region of the bosh section above the tuyere, wherein a stave arrangement structure of the shaft type metallurgical furnace is provided.

Claims

In the furnace height direction, in the furnace height direction of a shaft furnace type metallurgical furnace having a bosh portion, a cut portion and a shaft portion in order from the lower portion of the furnace, and having a tuyere at the lower end of the furnace, the upper and middle portions of the furnace where the heat load is small. (A) has a cast iron stave and has a stave arrangement structure in which copper or copper alloy staves are arranged in the lower furnace area (B) and lower furnace area (C) where the heat load is lower than that. So,
The furnace bottom region (B) is an upper region of the bosh section, a lower region of the entire region and the shaft portion of the Kittate portion, the furnace bottom region (C) is, is the lower region of the bosh section in the tuyere upward A stave arrangement structure of a shaft furnace type metallurgical furnace characterized by the above-mentioned .
