How to determine the appearance of quality surfacing wear-resistant lining and internal quality?

2015-02-04

A: The appearance of quality surfacing wear-resistant steel main judge from the following aspects:

a) Flatness: steel corners to simultaneously smooth landing.

b) weld cracking: liner to weld cracking evenly spaced, tiny cracks, expansion is not wide.

c) Surfacing size: the size of the liner cladding layer to low level, no significant irregularities. To ensure that the welding defects

Within a reasonable range.

d) Surface painting: surface paint Bohou liner should be uniform, playing putty should be uniform and smooth.

e) four weeks Cutting Edge: liner four weeks to form linear cutting edge, no flash; large plasma cutting machine good shape. The intrinsic quality of surfacing wear-resistant lining from the following aspects to determine

a) Wear layer thickness: polished Measure, surfacing significantly, taking multi-point measurements averaged. b) the total thickness of plate: control within the allowable range ± 0.5mm. c) Hardness: within the required range, HRC55-62
