H-shaped steel manufacturing method

Abstract

The invention provides an H-shaped steel manufacturing method. A bottom plate, a supporting frame, a flow guide hood, a shredding device, a pulverizing device, a spreading device and a screening device cooperate to complete environmental restoration of contaminated soil. The method solves the main problems existing in the process of forming a slotted hole through cutting in H-shaped steel by usinga cutting machine that on the one hand, in the cutting process, the H-shaped steel is easily shaken to cause an uneven notch surface and affect the later installation effect; on the other hand, the H-shaped steel is high in strength and hardness, the efficiency of cutting and slotting the H-shaped steel by using an existing cutting machine is low, a steel block obtained after cutting is difficultto take from the inside of the H-shaped steel, the steel block needs to be manually hammered by using a hammer, the surface of the H-shaped steel is easily damaged by manual hammering, and the rigidstructure of the H-shaped steel is affected.

Description

technical field [0001] The invention relates to the technical field of steel structure processing, in particular to a method for manufacturing and processing H-shaped steel. Background technique [0002] H-shaped steel is an economical cross-section high-efficiency profile with more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structural weight, and has been widely used. [0003] Some H-beams need to provide symmetrical through holes to their sides during installation in a specific use environment; but due to the specific structure of H-beams, the existing opening methods mainly have the following problems in the process of cutting them with cutting machines: ...

Problems solved by technology

[0003] Some H-beams need to provide symmetrical through holes to their sides during installation in a specific use environment; but due to the specific structure of H-beams, the existing opening methods mainly have the following problems in the process of cutting them with cutting machines: a : During the cutting process, the H-shaped steel is prone to shaking, causing the surface of the cut to be uneven, and affecting the installation effect in the later stage; b: The H-shaped steel has high strength and high hardness, and the existing cutting machine has low efficiency for its slotting and cutting process. Moreover, the cut steel block is difficult to remove from the inside of the H-beam, and it needs to be hammered manually with a hammer. Manual hammering is also likely to cause scratches on the surface of the H-beam; affecting its rigid structure
