What is cost-effective for use as guards on coke quenching vehicles?~
Thread Content
I’ve read a lot online~ Everyone says that ductile iron is a better choice~ But our factory uses ordinary steel, and the components made from it wear out more quickly. What’s the typical price of QT-400? What’s its service life when used for protective panels? Which is more cost-effective, QT-400 or ordinary steel? Also, for the parts requested by our maintenance team, aside from a very small number of items that are obtained directly from the manufacturer, the rest are manufactured by local factories. Not only is the quality poor, but it’s also unclear what materials are used. What’s ordered may not necessarily be made according to your specifications. I’m curious to know how other companies handle this aspect of things~
It’s best to use wear-resistant steel plates, as they have a longer lifespan and require less maintenance work.
The issue is wear-resistant steel – which option offers the best value in terms of cost-performance? When requests are made to purchase it, the refusal is always based on the high price. In the end, 45 steel is used after all
High-temperature deformation also needs to be taken into account. The quenching cars used in our factory’s 6.25-meter coke ovens are made of cast iron plates, which are wear-resistant and suffer less deformation; however, they still require careful daily inspection and maintenance, otherwise no material will do!
