Previously, a customer had a problem with short life in bull nose area. The bull nose only lasted 6-8 months, so HASLE proposed a Precast solution by using HASLE standard precast shape and curved precast shape.

The HASLE Precast Lining system is based on standard shapes to enable a smooth and easy installation. The system is developed in co-operation with in­stallation companies, HASLE engineers and with customers. 

The result is a lining system which ensures maxi­mum life.

The very low open porosity of the surface (10-12%), in combination with highly alkali resistant material, reduces build-up and protects from corrosion. In many process industries this lining has reduced, or even eliminated, the build-up. This ensures smooth running of the process and maximum output with a minimum of downtime
The precast refractory element has a tongue and groove joint on all 4 sides which is filled with 2mm mortar. This reduces the penetration of gasses to the insulation and the fitting system

HASLE Solutions compared to other?

Below are photos from inspections during shutdowns. Fig1. shows the Kiln area in excellent condition after 6 months, especially compared with similar area lined with Castables.
Fig.2 +3 shows the Bull Nose - after 18 months lifetime - where there was no wear on the precast element.

HASLE logo stands sharp

Excatly how well HASLE performs, it's possible to see on the HASLE logo which still stands presented sharp on the surface. And compared to the castable (not HASLE) installed in both sides of the precast there was more than 30mm. of wear.
