FORMING MECHANISM AND COTROLLING MEANS OF BONDING DEFECT IN COLD-ROLLED COIL

By means of analysis the bonding defect formed during batch annealing in cold-rolled coils, the forming mechanism of bonding was found. The influence factors of bonding defect, which includes annealing process, steel surface finish and cleanliness, coiling tension, plate shape, temper rolling process and so on, were analyzed. So the controlling means of bonding was gotten.
