A kind of lc shaped steel and its manufacturing method

Abstract

The invention discloses LC profile steel which comprises an inverted-L-shaped profile steel body, a first steel body and a second steel body. The first steel body and the second steel body are disposed at the top of the profile steel body and integrally connected with the top of the profile steel body. The first steel body is vertical to the top of the profile steel body. The included angle between the second steel body and the top of the profile steel body is smaller than 90 degrees, and the second steel body includes towards the first steel body. The invention further discloses a manufacturing method of the LC profile steel. The LC profile steel and the manufacturing method thereof have the advantages of high production efficiency, high steel strength, low energy consumption, low worker labor intensity, good work environment and environmental protection.

Description

technical field [0001] The invention relates to the field of steel product manufacturing, in particular to an LC shaped steel and a manufacturing method thereof. Background technique [0002] LC section steel is a section steel with special structure. Its structure is a combination of L-shaped structure and C-shaped structure in different directions. This complex structure also determines the complexity of its production process. [0003] Traditional LC section steel is mainly produced by welding angle steel and flat steel in terms of production technology. The process is to roll the billet into angle steel, flat steel 1 and flat steel 2, and then cut and blank the material before welding. Sanding and straightening is the final step. This manufacturing process has the following disadvantages: [0004] 1. Its production efficiency is low because it has many processes and the welding speed is limited by the on-site environment; [0005] 2. The strength of the steel after fo...

AI Technical Summary

Problems solved by technology

[0004] 1. Its production efficiency is low because it has many processes and the welding speed is limited by the on-site environment;

[0005] 2. The strength of the steel after forming is not high, because the steel is composed of three parts, and its strength is far less than that of the whole steel;

[0006] 3. The energy consumption is too high, and the labor intensity of the workers is high;

[0007] 4. The working environment of on-site construction is poor, which is not only not environmentally friendly, but also produces a lot of smoke and dust and waste residue during the welding process

[0008] Furthermore, the traditional LC section steel is generally a single-steel rolling machine, a double-steel rolling machine, and at most a three-steel rolling machine, with a small number, which cannot be effectively flow-lined, cannot cooperate effectively with each other, and has low production efficiency

[0009] Furthermore, traditional LC section steel has less design for the thickness and angle of each component in terms of section steel structure, and cannot effectively realize the function of section steel while saving steel materials

And in the process of production and processing, there is less consideration on how to cut and use materials to ensure the maximum utilization rate of LC steel, resulting in a certain waste

[0010] Furthermore, the traditional LC section steel lacks the strengthening of steel strength during the manufacturing process, so that the expected forming quality cannot be achieved during the rolling forming process
