Steel belt coil strip surface cleaning shot blast machine
Carbon/stainless Steel belt coil strip surface cleaning shot blast machine
The Steel coil/Strip Shot Blast Machine are used for descaling of carbon steels, stainless steels ranging from 350 to 2100 mm width, shotblasting speed : 2 meter to 20 meter/min or more. Eliminates pickling, surface is completely free of scale, Steel Strip Shot Blasting Machine can be installed in individual or inline process. Operation is simple require minimum labour.
Shot blasting carbon & stainless steel strip as illustrated as above, sized 350 to 1800 mm width are shot blasted at 2 to 15 meter per minute. Shot blasting has much advantage compare to pickling. Shot blasting removes scale completely does not remove virgin metal, operation is simple requires minimum of labour and space. The floor area taken by shot blasting installation is much less than acid pickling area. No effluent disposal problem, the operation is cleaned and cost is very low.
Blast wheel arrangement and concept ensures maximum exploitation of blasting energy and intensity and prevents from blasting interferences
Efficient abrasive blow-off, maximum abrasive cleaning and recovery, efficient dust collection
High wear-resistant execution of parts subject to wear
Continuous further development ensures application of latest technology
High performance mechanical descaling of steel strip (stainless and silicon steel, low carbon, titanium) integrated in highly sophisticated continuous production lines
Type series ranging up to strip widths of 600 mm / 1650 mm / 2100 mm
Modular concept meeting production requirements
Machine Design and Mode of Operation
The machines consist of self-contained and can be installed with or without foundation pit.
Structural features and sub-assemblies:
Blast cleaning cabin made of hard manganese steel: Four blast wheels for each module, two for the upper side and two for the underside of the strip. Rubberised rollers located at the entry and exit sides of the blast cleaning cabin serve to support the strip
Abrasive removal device: After each blast cleaning cabinet, a compressed air blower removes abrasive residue from the upper side of the strip and returns it to the abrasive circulation system for re-use
Abrasive return and reconditioning system with pneumatic separator: A pneumatic separator cleans the circulating abrasive. Aligned to consumption, new abrasive is supplied. As a result, the operating mix and blast power are constantly maintained
Dust extraction system: Blast cleaning and abrasive removal cabinet, circulatory system and separators are connected to the dust collection system
The strip roll-out can be straight or run diagonally upwards, depending on the arrangement of the module groups and the subsequent pickling operation.
Safe Operation, Simple Maintenance
The design concept of the blast cleaning system transports the strip without damaging the surface. Thorough abrasive cleaning and complete dust extraction render the strips leaving the machine cleaned. Simple, but highly effective sealing elements prevent stray abrasive from interfering with the machine operation.
Large service doors and the special structure configuration permit easy access for inspection and maintenance work. All blast wheels are easily accessible for periodic check-ups and replacement of wear parts or sub-assemblies. Components with close tolerance allow fast removal and installation of spare parts.
Savings in Production Cost
Integration in existing production lines is possible without major modification work. Optimum utilisation of the blast cleaning power covering the whole width of the strip helps to obtain a high degree of cleanliness after
