Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments (the templates described in the embodiments are all pre-tested templates, and the templates have the same radian as the actual required radian, which is convenient for detection): see Figure 1 to Figure 2 , a kind of equipment used in the two-way rolling process of shaped steel, including a base 1, on which a fixed platform 2 for placing shaped steel is arranged, and a first driving mechanism 3 is arranged on one side of the fixed platform 2, said The first drive mechanism 3 is connected to the profiled steel support 4. When the profiled steel is placed, the profiled steel is first put into the fixed platform 2, and then the first drive mechanism 3 promotes the profiled steel bracket 4 so that the profiled steel is firmly fixed on the fixed platform 2.

[0014] A second drive mechanism 5 is arranged above the fixed table 2, and a tire me...

Abstract

The invention discloses a section steel bidirectional winding technology and equipment used in the section steel bidirectional winding technology. The section steel bidirectional winding technology mainly comprises a section steel sidewise winding technology and a section steel radial cone shape winding technology. Through the section steel bidirectional winding technology, sidewise bending winding of various types of section steel which includes section steel, H section steel, joist steel, angle steel and the like can be well completed without purchasing new equipment, and the difficulty of sidewise bending winding of the section steel is solved. Moreover, winding of the products which have special shapes can be completed efficiently, and not only are sidewise winding and radial big end and small end winding of the section steel are solved, but also manufacturing precision is high and drawing design requirements can be realized conveniently.

Description

technical field [0001] The invention relates to a process for two-way rolling of section steel and equipment required for the process. Background technique [0002] The world's first third-generation AP1000 nuclear power third-generation containment passive water tank module CB20 undertaken by the applicant is a stainless steel plate lining for passive containment cooling water storage tanks, which belongs to Class C nuclear safety equipment. The module consists of four parts, including the top of the box, the outer wall of the box, the inner wall of the box and the bottom of the box. The bottom of the box is a cone sub-module. The connection between the sub-module and the bottom sub-module and the inner wall sub-module is equipped with a cone-shaped leak detection steel. The cone-shaped steel needs to fit closely with the inner wall sub-module and the bottom sub-module. In the shape of a cone, the material is American Standard stainless steel A276 TP304L, and the specifica...
