HIP growth rate to slow
Walking beam furnace caters f o r customer needs Its new walking b e a m furnace h a s been designed so t h a t t h e varying n e e d s of customers can be met, claims Lenton Thermal Designs of Market Harborough, UI~ The WBF-Series walking b e a m furnace is designed along m o d u l a r l i n e s s u c h t h a t its o p e r a t i o n a l t e m p e r a t u r e , lateral d i m e n s i o n s a n d length of traverse may be tailored to t h e r e q u i r e m e n t s of individual customers. In s t a n d a r d form t h e c h a m b e r d i m e n s i o n s are 500 x 500 mm, length 2.2 m. Three zone h e a t i n g is p r o v i d e d by spiral w o u n d e l e m e n t s supported by ceramic t u b e s positioned below t h e b e a m s a n d in t h e c h a m b e r ceiling. These provide operational t e m p e r a t u r e s u p to
1150°C. There are five parallel b e a m s in t h e base of t h e c h a m b e r , t h r e e of w h i c h effect s t a t i c support. The two walking b e a m s are provided with variable speed control enabling t h r o u g h p u t times from a minim u m of one h o u r to be selected. Each e n d of t h e c h a m b e r is fitted with a m e s h s u r r o u n d for user protection, a n d access is provided via electrically lifted doors.
