High-Tech Tunnel Kiln Put into Operation at P-D Refractories CZ a.s.

24.11.2020

The fact that high-quality products can only be manufactured thanks to modern equipment applies to the refractory industry as to any other industrial branches.

 

That was the main motivation why we decided to move forward with the investment of EUR 4 million for the complete modernisation of the tunnel kiln in the Velké Opatovice plant. The new kiln with a length of 154 m and maximum firing temperature of 1,550ºC meets the strictest ecological requirements and it is equipped with an original heating system that the kiln supplier used for the very first time. Intelligent heat recovery and a fully automated operation, including the tunnel kiln car transport, is a technical standard in contemporary plants.

Stabilisation of the foundations using micro-piling was a great challenge for the furnace builder. At the beginning of September 2020, the furnace is now in operation as planned. When the operating temperature was reached after several days, we started firing fireclay goods, followed with other products that require a temperature of up to 1550ºC. The perfect execution of the construction and all the equipment has also been confirmed by the fact that the complete test run was performed smoothly.

 

In addition to providing flexibility, higher quality and capacity, the new tunnel kiln also allows us to fire silica goods.

 

This fact considerably contributes to complete management of orders in the field of the coking-

making industry, which is one of the main strategies of P-D Refractories CZ a.s.
