Effect of the initial cladding ratio 5.40%-15.53% with 0.45C steel

NM360 abrasion-resistant steel

310S and 316 stainless steel 5.1-15.2 mm initial cladding plate and Q345 carbon steel 82.7-90.0 mm initial base plate and the total reduction 35%-75% on cladding ratio of clad steel plate hot-rolled at 1150-1000 ℃ has been tested and studied by using two-high reversing mill. Results show that as the resistance to deformation of cladding plate (316 and 310S steel) is larger than that of base plate ( Q345 steel)

with increasing reduction the cladding ratio of plate increases

and the larger the initial cladding ratio

the increasing cladding ratio of hot-rolled plate more obvious; as the resistance to deformation of cladding plate (0.45C steel and NM360 steel) is smaller than that of base plate ( Q345 steel)

with increasing reduction the hot-rolled plate cladding ratio decreases ; the relation between change rate Y of synthetic relative reduction of cladding ratio and strength difference S

d

is Y = (-0.12 ±0.17) + (0.068 ± 0.004) S
