Dalmia Seven News

After the first successful trial for Ultratech Cement Limited in Rajashree, Dalmia Seven has performed another castable installation at the client’s plant in Sidhi.

The new trial focused on the burner pipe, which is subject to a number of challenges such as:

  • High temperature
  • High thermal shocks
  • High chemical attacks
  • High abrasion due to clinker dust

In order to achieve the desired good thermal stability at all temperatures as well as optimal resistance against thermal shock, alkali attack, and mechanical abrasion, a castable with high content of alumina and low content of cement was selected.

Installation and Evaluation

The trial was performed under Dalmia Seven’s technical representative Bhawesh Nigam, who summarizes the key facts: ‘Given the technical analysis of the plant and its requirements, we decided to use DS Cast 80 NH as a product for the burner pipe in Sidhi. The entire installation of 5 MT of material was successfully completed in the month of December 2018.“

The Burner pipe will be put in operation in Feb 2019 and both the parties will jointly monitor performance of installed castable. A joint inspection will also be done during the next shutdown following after Feb 2019.
