JSC “Dneprotyazhmash” is delighted to announce successful manufacturing and delivery to PJSC “Tulachermet” another bell-type (cone-type) top charging unit 5400 mm in diameter. It is to be used at the Blast Furnace No. 3 for dispensing and lockage of charging materials, as well as gas-sealing of blast-furnace mouth.
Bell-type top charging units of JSC “Dneprotyazhmash” design and production, consisting of cone and cup, have high wear-resistant properties of its contact and protect surfaces though the use of chromium carbide welded layer. Gas-tightness of the equipment is ensured by firm adherence of contact surfaces that is achieved as a result of fine polishing of these surfaces on very precise equipment. Geometry stabilization during machining and stress relieving are ensured by specially adjusted heat-treatment conditions.
This is not the first bell-type top charging unit that JSC “Dneprotyazhmash” supplies to PJSC “Tulachermet”. Largest in its range, 5400 mm diameter top charging unit has already been delivered to this Customer in 2013 and 2017. The fact that average durability of top-charging units is around two years proves that Dneprotyazhmash-made equipment has high exploitation properties and increased operationability.
