[0053] Target size of rolled steel plate: thickness 20.12mm, width 4307mm, length 17304mm.

[0054] Transfer steel code RS=5, use RS=5 for rolling, the width ratio is 1.45, the slab size during the rolling process is: 1700mm+10mm=1710mm.

[0055] Forming MAS depth: -1.5mm.

[0056] Widened MAS depth: -4.5mm.

[0057] Before the slab comes to the thick plate rolling mill, it is first rotated 90° for the first time. After the rotation is completed, it is formed and rolled, and the formed MAS rolling is performed in the last pass of the formed rolling (the depth of the formed MAS is -1.5mm); the formed MAS After the rolling is completed, the slab is rotated for the second time. After the rotation is completed, the widening rolling is carried out, and the slab is rolled into the 4307mm width size required by the customer. The widening MAS rolling (widening MAS rolling) is carried out in the last...

Abstract

The invention relates to a thick plate rolling method which comprises a shaping rolling procedure, a broadening rolling procedure and a fine rolling procedure, wherein shaping MAS (mizushima automatic planview pattern control system) rolling is used for one time during the rolling process of a plate blank through three times of rotation, and the planar shape control to the plate blank is carried out by using broadening MAS rolling for one time, thereby the planar shape of a steel plate is greatly improved, and the rolled steel plate is approximately rectangle shaped, so that the steel plate yield is increased. Compared with the yield of an existing transverse rolled material, the planar shape of the rolled steel plate is improved, thereby the yield of each transverse rolled material using the thick plate rolling method is increased to 93-94%.

Description

technical field [0001] The invention belongs to the technical field of steel rolling, and in particular relates to a thick plate rolling method, which is realized by controlling a thick plate rolling mill. Background technique [0002] Steel plates with a thickness of more than 4mm are called medium and thick plates, referred to as medium and heavy plates. It is used in shipbuilding, building components, machine manufacturing, transportation, military industry and other departments, as well as in many fields of the national economy such as large-diameter welded pipes, containers, boilers, etc. The level of its technology and equipment directly affects the finished product of the product. Rate. [0003] The thick plate rolling process is a process of rolling a slab of a certain size into a steel plate of a certain size. Since the width of the incoming slab is different from the width of the finished steel plate required by the customer, the rolling method used in the rolling...
