Furnace car family

Pallet cars make up the the travelling grate moving the pellets inside the furnace. The cars are made up of several parts. The cars will see intense heat in the main firing zones (up to 1350 deg. C) and cold air will go through them in the cooling zone. Special materials are required for manufacturing the car’s part to withstand the high temperature and the thermal cycling they are exposed to.

Metal 7 offers a variety of parts thanks to its association with modern foundries specialized on high temperature alloys.

Challenge

Pallet cars are used in straight grate travelling grate indurating furnace to convey the pellets through the different firing zones.

Most of pallet cars parts are made of costly high temperature stainless steel alloys.  They are custom made for each plant requirements.  Planners and purchase department have to follow closely their inventory and their upcoming needs to cope with the very long deliveries from the foundries producing the castings.  Main producers are now located in Asia which extends even further the deliveries.

It is common for plants to stock important quantity of those castings to compensate the long lead-time associated with new orders.

Quality in the metallurgy and the chemistry of the cast parts varies a lot on the market.

The performance in service and the life of the parts would fluctuate considerably with the variation in quality. Unfortunately, the impact of the casting flaws will take time to appear in service delaying the implementation of solutions.

The challenge for the pelletizing plants is to identify a reliable source for the castings, one that would provide high quality parts, a consistency in the quality with reasonable delivery time.
