Further, the judging whether the cold-rolled blocked steel coil is a galvanized coil further includes: when the cold-rolled blocked steel coil is a galvanized coil, checking whether the weight characteristic value of the zinc layer of the cold-rolled blocked steel coil is the same as the weight characteristic value of the zinc layer of the second order, and if not, stopping circulation; and if the cold-rolled blocked steel coil meets the weight requirement of the second order, the circulation is stopped.
Specifically, the second order is the retrieved appropriate to-be-produced order, in other words, the second order is the new order, and the appropriate to-be-produced order is retrieved according to the re-matching order algorithm for the default cutting scheme, as shown in fig. 2, the re-matching order algorithm is detailed as follows:
step 141: checking the size specification; the method specifically comprises the following steps: firstly, checking the thickness H of the cold-rolled blocked steel coil0Whether or not to satisfy the aboveThe second order thickness requirement, i.e. when H1+ΔHLower part≤H0≤H1+ΔHOn the upper partWhen the requirement of a new order is met, the width specification can be checked; otherwise, the new order requirement is not met, and the cycle is terminated. Secondly, checking whether the width of the cold-rolled blocked steel coil after being sheared meets the width requirement of a new order, namely when W is1+ΔWLower part≤W0-2W*≤W1+ΔWOn the upper partIf so, indicating that the new order requirements are met, the checking of step 142 can be performed; otherwise, the new order requirement is not met, and the cycle is terminated. Wherein H1Representing the thickness target value of the new order in mm; Δ HOn the upper partAnd Δ HLower partRespectively representing the upper deviation value and the lower deviation value of the thickness of the new order, and the unit is mm; w1Representing a new order width target value in mm; Δ WOn the upper partAnd Δ WLower partRespectively representing the upper deviation value and the lower deviation value of the width of the new order, and the unit is mm; w represents the amount of unilateral shear in mm.
Step 142: checking chemical components; the method specifically comprises the following steps: the actual chemical composition values of the cold-rolled blocked steel coil comprise all elements which can be checked, and comprise single conventional elements such As C (carbon), Si (silicon), Mn (manganese), P (phosphorus), S (sulfur), Alt (total aluminum), Als (acid-fused aluminum), N (nitrogen), Nb (niobium), Ti (titanium), V (vanadium), Cr (chromium), Ni (nickel), Mo (molybdenum), Cu (copper), B (boron), single residual elements such As (arsenic), Sn (tin), Ca (calcium), Zr (zirconium), W (tungsten), Sb (antimony), Pb (lead) and element composite items P + S (phosphorus-sulfur sum), Ceq (carbon equivalent), Csol (excess carbon), Nb + Ti + V (niobium-titanium-vanadium sum), Ni + Cr + Cu (nickel-chromium-copper sum), Ca/S (calcium-sulfur ratio), Mn/Si (manganese-silicon ratio), Alt/N (total aluminum-nitrogen ratio), Als/N (acid-fused aluminum-nitrogen ratio), Cu/Ni (copper-nickel ratio). Checking whether the actual values of the chemical elements of the cold-rolled blocked steel coil meet the chemical composition requirements of a new order, namely respectively checking whether the actual values of all the elements are within the element up-down deviation according to the chemical composition element items of the new order, and when C is within the element up-down deviation1+ΔCLower part≤C0≤C1+ΔCOn the upper partWhen the C (carbon) element requirement of a new order is met, C (carbon) element requirement is met0Representing the actual value of the C (carbon) element of the cold-rolled blocked steel coil; c1Representing a new order C (carbon) element target value; delta COn the upper partAnd Δ CLower partRespectively representing the upper and lower deviation values of the C (carbon) element of the new order; other elements are similar to this specification. Checking the next Si (silicon) element according to the element sequence; otherwise, the new order requirement is not met, and the cycle is terminated. And when all the required elements of the new order are checked, and the chemical elements of the cold-rolled blocked steel coil are checked to meet the requirements of the new order, the step 143 is entered, otherwise any element does not meet the requirements of the new order, and the cycle is terminated.
Step 143: checking the mechanical property; the method specifically comprises the following steps: the mechanical properties of the cold-rolled blocked steel coil comprise yield strength ReLTensile strength RmElongation after fracture A80Plastic strain ratio r90Work hardening index n90、BH2Value, etc. check term. Checking whether the mechanical property actual value of the cold-rolled blocked steel coil meets the mechanical property requirement of a new order, namely respectively checking whether the actual value of each check item is within the vertical deviation of the actual value according to the mechanical property check items of the new order, checking whether the mechanical property actual value of the cold-rolled blocked steel coil meets the mechanical property requirement of the new order item by item, and dividing the two conditions into two types, wherein when the mechanical property requirement item of the new order item is less than the mechanical property actual item of the cold-rolled blocked steel coil, when all the mechanical property check items of the new order item are checked to be finished and the mechanical property actual value of the cold-rolled blocked steel coil meets the requirement of the new order item, the subsequent step is carried out, otherwise, the circulation is terminated; and secondly, when the mechanical property requirement item of the new order is more than the mechanical property actual item of the cold-rolled blocked steel coil, when any one of the checked existing inspection items does not meet the requirement of the new order, the circulation is terminated, when all the existing inspection items meet the requirement of the new order, an alarm prompt is sent, the mechanical property value is required to be re-detected in the rewinding line, when any one of the newly-detected mechanical property values does not meet the requirement of the new order, the circulation is terminated, and when all the newly-detected mechanical property values meet the requirement of the new order, the subsequent steps are carried out. When R iseL(lower limit) R is not more than ReL(actual) R is less than or equal toeL(upper limit) indicates satisfaction of new order yield strength ReLIt is required that the tensile strength R is conducted in the above ordermChecking; otherwise, the new order requirement is not met, and the cycle is terminated. When all the mechanical property inspection items of the new order are checked, the cold-rolled blocked steel coil is checkedWhen the actual values of the mechanical properties meet the requirements of the new order, the step 144 is entered; otherwise, the actual value of any check item does not meet the requirements of the new order, and the cycle is terminated. Particularly, if the number of the mechanical property check items of the new order is more than that of the existing mechanical property check items of the cold-rolled blocked steel coil, the existing check items after checking meet the requirements of the new order, the circulation is not stopped, an alarm prompt is given, and the mechanical property value is detected again by sampling on a rewinding line. Step 144 is entered.
Step 144: checking the surface quality; the surface quality grades of the steel coil are FD, FC, FB and FA from high to low respectively, and the cold rolling blocked steel coil surface quality judgment result is one of the grades. And checking whether the actual value of the surface quality of the cold-rolled blocked steel coil meets the surface quality requirement of the new order, namely the actual value is not lower than the surface quality requirement of the new order, such as the surface quality requirement FB of the new order, and the actual grade of the surface quality of the required steel coil is FB, FC or FD. Because the edge defects or the head and tail defects which affect the surface quality grade can be removed through shearing optimization, the surface quality grade after the defects are removed meets the surface quality requirement of a new order. When the actual value of the surface quality of the cold-rolled blocked steel coil does not meet the surface quality requirement of a new order, the circulation is not stopped, an alarm prompt is given, and quality service personnel can give a shearing optimization scheme by combining a steel coil defect map. Then, step 145 is entered.
Step 145, check the weight. The weight includes two weight items, the first is the coil weight and the second is the zinc layer weight. Wherein the zinc layer weight is only applicable to orders whose product type is galvanized coil. Firstly, judging whether the product type is a galvanized coil or not, and directly checking the weight of the steel coil if the product type is not the galvanized coil.
