Ratio of upper to lower large springs in the coke oven
Thread Content
I read in the technical specifications of a certain coking plant that the tonnage of the springs at the lower part of the coke oven is 0.75 times that of the springs at the upper part. Is this statement correct?
Yes, where does 0.75 come from? I really want to know why too! !
This statement is inaccurate. How should it be expressed correctly in the regulations? Please advise
Taking the 6.25m ramming coke oven as an example. After normal operation, the tonnage of the upper spring is 12.5 tons, while that of the lower spring is 21 tons. Therefore, the ratio of the lower spring to the upper spring is: 21 : (12.5 × 2) = 0.84, which is not 0.75. Where did 0.75 come from? This was summarized by the experts from Gengyang Coking Plant. The reason for multiplying the upper part by 2 is that there are 2 cross braces in the upper part, while there is 1 cross brace in the lower part.
