Embodiment

[0052] The specification of the blank of this embodiment is the continuous casting billet (material Q345) of 160 * 160mm section, comprises the following steps:

[0053] 1) Heating the billet to 1100-1150°C;

[0054] 2), utilize the billet opening machine that is provided with 6 passes to carry out rough rolling to the billet heated in step 1), obtain the rolled piece after 8 pass rollings;

[0055] The billet opening machine is arranged with six pass types of K1, K2, K3, K4, K5, and K6 in sequence. image 3 As shown, K1, K3, and K5 are all longitudinal openings and split holes, such as Figure 4 As shown, K2, K4, and K6 are all transversely opened cutting holes. The longitudinal opening cutting hole is used for forming the flange 2 and the corner 3; the transverse opening cutting hole is used for the widening and thinning of the web 1, and the thickness of the web 1 of the rolled piece obtained after rough rolling is 16mm .

[0056] 3), using 3 universal rolling mills and...

Abstract

The invention provides novel section figured steel and a production method of the novel section figured steel. The section figured steel comprises a web, flanges and corners. The left end and the right end of the web are each provided with one flange, the upper end and the lower end of each flange are each provided with one corner, and the web, the two flanges and the four corners are integrally formed. The transverse center line of the web is A-A, the vertical center line of the web is B-B, one end of each corner is connected with the corresponding flange, and the other end of each corner isextended in the direction away from B-B. By means of the technical scheme, the production efficiency and the metal utilization rate are improved, the production cost is reduced, using economy is improved, the section figured steel is obtained after strengthening I-shaped steel, lateral bending resistance is high, and compared with traditional section I-shaped steel, the section is optimized, and the bearing capacity is higher.

Description

technical field [0001] The invention relates to the technical field of hot-rolled profiled steel, in particular to a novel cross-section profiled steel and a production method thereof. Background technique [0002] The traditional I-beam has a very wide range of applications, but in some professional fields, the traditional I-beam can no longer meet the requirements due to its small section modulus or weak bearing capacity. [0003] Special-shaped steel (special-shaped cross-section steel) is generally used in professional fields, and with different application fields, the cross-sectional shape is also different. [0004] Special-shaped steel is widely used in warehousing and logistics machinery, construction machinery, mining machinery and other fields, and with the deepening of research and expansion of applications, it is gradually extending to other industries. Contents of the invention [0005] The object of the present invention is to provide a novel cross-section s...
