Advanced Material Handling offers a wide range of products for rotary kilns for both the pulp and paper and cement industries. We specialize in the manufacture and sale of kiln chains, shackles, and hangers.
We manufacture these in various sizes and material grades based on your specific kiln operation conditions.
Heat transfer rotary kiln chains are manufactured in various sizes ranging from 3/4” to 1-1/4” diameter.
Kiln chains can be supplied in many materials such as: carbon steel, alloy steel, through-hardened alloy steel, and stainless steel.
Our kiln chain shackles are manufactured to suit various tombstone hangers. They are manufactured using a lost wax investment casting process. We have chosen this process to increase surface finish and reduce machining costs.
They are manufactured to order in several material grades ranging from 8630 alloy to 310 stainless steel.
Advanced Material Handling kiln chains are supplied in materials ranging from carbon steel to high temperature stainless steel. The welding process in done robotically and supplied in cut-to-size lengths.
The right selection of material components will provide the best service life and prove to be most cost effective over time. Kiln operation temperature, gases, and method of firing are the primary elements in the selection of material.
In the first section or “cold section” where the normal gas temperature is below 500 degrees Celsius, carbon steel chains can be installed. If this section is a high wear area we would suggest using a heat treated through-hardened chain and hanger system.
When compared to carbon steels, alloy steels have higher core hardness and will provide better service in temperatures ranging from 300 to 500 degrees Celsius.
These material grades are the most resistant to sulphurous gases, but are less suitable for nitrating and carburizing environments. These steels are best suited for kilns that are fired with gas or oil.
This material is the most resistant to carburizing conditions, but is not suited for atmospheres with sulphurous gases present. Austenitic manganese steel is suited for kilns with sulphur containing gases with carburizing conditions. These chains offer superior toughness and work hardening properties.
