热风多排小风口冲天炉这是由原冷风冲天炉改造成热风多排小风口曲线炉膛的冲天炉。其铁水温度最高可达1400～1410℃(光学高温计读数),焦铁比由1∶6提高到1∶8～9。主要技术参数:炉子熔化率2(1/2)吨/时;前炉量1.5吨;炉缸处直径550毫米;主风口处直径600毫米;熔化带处直径750毫米;密筋炉胆, Multi-row hot air cupola This is converted from the original cold cupola into hot air multi-row small outlet curve cupola furnace. The hot metal temperature up to 1400 ~ 1410 ℃ (optical pyrometer readings), iron from 1: 6 increased to 1: 8 ~ 9. The main technical parameters: furnace melting rate of 2 (1/2) tons / h; before the furnace capacity of 1.5 tons; furnace cylinder diameter of 550 mm; diameter of 600 mm at the main tuyere; melting zone at a diameter of 750 mm;
