Walking Beam Cooling Bed

The walking beam cooling bed and continuous casting billet turnover cold bed series products are mainly applicable to bar, profile and billet production lines in iron and steel smelting industry. The step-by-step cold bed can meet the annual production capacity of 100-1 million tons.

The walking beam cooling bed consists of four parts, i.e. feeding system, body of the cold bed, leveling device and feeding device. The feeding system uses cylindrical roller bed to be tilted and positioned. Frequency converter roller bed motor drives independently. The feeding on roller bed is braked by a single skirt. The feeding mechanism includes curved plate type, pinch roll belt trough type and brake apron type. Brake apron lifting includes hydraulic, mechanical and other structural forms. The cold bed is step-by-step. Input roller is controlled by frequency conversion or driven directly by AC, while output roller is driven by AC.

Walking beam cooling bed is the working table for effective cooling of rolled products (threaded steel, round steel, steel pipe, etc.) in metallurgical rolling steel industry.

Classification:

 The walking beam cooling bed mainly include pull-tooth type, rack step type, pawl type, chain type and roller type.

Composition: 

The walking beam cooling bed consists of mechanical transmission system, water cooling system, working table of the cold bed, fixing support, etc.

Working principle: 

The rolled products are conveyed into the cold bed through the roller track, and then the work pieces arranged on the cold bed are moved to the top of the cold bed step by step by step by rack pulling the teeth. The cooling effect of the work pieces is achieved.

Main application: 

The walking beam cooling bed equipment is mainly used for slow natural cooling of rolled steel plate on-line. On the profile production line, the cold bed also has the function of pre-bending the profile to prevent irregular bending of the profile due to unequal quality everywhere during the natural cooling process.

Application field: 

Walking beam cooling bed is mainly used in iron and steel industry, metallurgical industry, etc.

Environment and Conditions for Equipment Use: 

Ambient Temperature: -20-+40 C

Working environment: not suitable for flammable and explosive

Altitude: +108 M
