Spring tonnage
Thread Content
We recently measured the longitudinal and transverse struts; the indicated temperature dropped, and so did the actual air temperature. I thought that the furnace body would contract and its tonnage would decrease, but in fact it increased significantly. Dear sea friends, which has a greater impact on the spring tonnage: the elevation temperature of the coke oven or the changes in weather temperature?
When the standard temperature is changed, the expansion and contraction of the furnace body cannot be that significant. The reason is that, when talking about standard temperature, it refers to the coke ovens used in production, whose temperature must be at least around 1200°C. At this temperature range, silica bricks do not have a lattice transformation point; moreover, the standard temperature is not changed suddenly
Due to reduced production, the standard temperature is 1170. I want to know how changes in standard temperature and air temperature affect drawing bars. The temperature is low now, but the tonnage is higher – what’s the reason?
