Furnace hearth structure of molten pool smelting furnace

The utility model provides a furnace hearth structure of a metallurgic melting bath smelter hearth with a metal pyrogenic process. The utility model is characterized in that the bottom of the furnace hearth forms an incline, the head inclination is 1 DEG, the middle part inclination is 15 DEG, the tail inclination is 1 DEG, the bottom of the furnace hearth has different depth, the distance between a center line of a copper water cover wind opening being far away from the head and the middle part is about 800 mm, the distance between the tail and the center line of the wind opening is about 1300 mm, and the width becomes small, thereby being favorable to the blow on of the solid. Because the depth of the furnace hearth in not large, needed wood and fuel are less, the melting bath can be made with less melting mass. The head and the middle part of the furnace hearth are positioned below the wind opening, the depth of 800 mm can cause that the melting mass be separated to flow down along the incline, with full h
