Tuyeres and Goosenecks
These linings are repeatedly bombarded with blasts of hot air (thermal shock) and at times added coal (mechanical shock). Fibre-reinforced refractory will resist these forces which otherwise crack and spall castable, shortening its working life and increasing maintenance costs.
Recommendation: ME 446
Working Floor Area
Hot metal splash and mechanical wear from heavy plant can crack casthouse floor concrete, making movement difficult and sometimes dangerous. Fibres are ideal here with economies often of 200-300%.
Recommendation: ME 430
Upper Stack
In the Upper Stack mechanical abrasion is caused by the impact of the charge and subsequent settling in layers. While some cracking is unavoidable ME fibres contain and minimise damage. Lining improvements have resulted in significant reductions in interim gunning repairs and maintenance costs.
