Bundle Coiled Wire Steel Bar Shot Blasting Machine

Description

About the coiled wire shot blasting machine
This type machine is the best special equipment which used to cleaning the wire rod, it clean the scale cinder on the surface of the wire and the squama layer on the rolled steel through the blasting process.The surface descaling grade of the steel billet rust reach Sa2.5 level after cleaning, and the surface roughness level reach Ra6.3 ~ 12.5μm. Compared to pickling treatment, it have the characteristics of economy, environmental protection and high efficiency.
This machine use unique "revolving door + double cantilever axis" to bear the weight of wire rod, it achieve duplex mode of operation, and greatly increase the production capacity of the equipment. Cantilever shaft is made by special alloy steel, the wire make the compound action of "up and down + swing around + forward and reverse rotation" in the shot blasting process, in order to achieve the effect of thorough clean. Because of the reasonable blast wheel arrangement, the inner and outer surfaces of the wire rod can be effectively blow by the projectile beam. The machine is controled by PLC, HMI visual monitoring, and it is convenient and reliable operation.

Main technical index (acceptance inspection standards)
1. main technical index
Specification of wire rod:
A.diameter of the wire: Φ 4～Φ 36mm
B.inner diameter of the wire rod: Φ 800-1100mm
C.outer diameter of the wire rod: Φ1200-1400mm
D.height of wire rod: 2500mm
E.maximum load: 2500kg(diameter of wire rod:φ4～φ36mm)
Load mode and productivity:
A.means of delivery: cantilever shaft loading ( When shot blasting, indoor cantilever shaft can works accroding to the PLC program: clockwise rotation 15s, then counterclockwise 15s; the rotation time is adjustable. Outdoor cantilever shaft is controled by manual push-button, it is adjusted by staff through the electrical work station )
B.productivity: 7-13 min/rod
C.effective length:3800mm
D.rotation speed: 10-20 r/min ( frequency control )
3.The surface quality requirements after cleaning
A.No scale residual on the surface of the rolled steel after shot blasting
B.surface clearness: Sa 2.5 level
C.surface roughness : Ra6.3～12.5
4.environmental requirement
A.Outdoor emission concentration: ≤60.0 mg/m3

Cleaning effect

Accroding to the feature of wire rod, the machine adopts the ThyssenKrupp technology, six direct-type blast wheel is install on the rear side surface of the chamber body, and the machine throw out the projectile which th espeed is 80m/s and shot blast the wire rod. The machine also meet requirement of efficient automatic shot blasting accroding to the BE-shaped separator systems, high strength belt elevator, screw conveyor horizontally conveying projectile, two-stage long fiber polyester filter cartridge dust purification system (inertia + cartridge), automatic + manual HMI electrical control system.
