34.冲天炉的送风强度是什么意思? 冲天炉所需风量的大小,以每分钟鼓入每平方米炉膛截面积的空气量来衡量,称为送风强度。常用的送风强度为100～160m~3/(m~2·min)。 35.风压对冲天炉熔炼有什么意义? 冲天炉熔炼要有一定的风压来克服送风阻力,保证所需要的风量进入炉内。冲天炉所需风压的大小,主要由冲天炉炉内阻力所确定,其影响因素有:炉子 34. What is the meaning of the air supply intensity of the cupola? The amount of air required by the cupola is measured by the amount of air per square meter of the hearth cross-sectional area per minute, which is called the air supply intensity. Commonly used air supply intensity of 100 ~ 160m ~ 3 / (m ~ 2 · min). 35. Air pressure hedge furnace smelting What is the significance? Cupola smelting have a certain amount of wind pressure to overcome the air resistance, to ensure that the required amount of air into the furnace. Cupola wind pressure required size, mainly determined by the resistance of the cupola furnace, the impact of factors are: stove
