The invention relates to the field of construction technology, and discloses an anti-deformation correction process for narrow-section H steel, which includes the steps of steel rust removal, steel blanking, T-shaped assembly, T-shaped gate welding, anti-deformation treatment and the like. The anti-deformation treatment is to pre-press the second flange plate with a straightening machine, so that the two ends of the flange plate two are bent in the same direction to form a certain distance from the original plate surface. The bending direction of the two ends of the flange plate is a direction away from one side of the web plate. The T-shaped member in the narrow-section H-shaped steel and the single flange plate are subjected to pre-compression and anti-deformation treatment before assembly and welding, so that the flange plate of the H-shaped steel after assembly and welding will expand due to thermal expansion and contraction at the weld. The natural correction is retracted to offset the anti-deformation, so as to achieve the correction effect on the narrow section H-beam, which not only reduces the labor intensity of people, but also improves the correction efficiency and reduces the production cost, so as to ensure the production and delivery of H-beam. .

The invention discloses an environment-friendly aluminum cleaning agent and a preparation method thereof. The cleaning agent is composed of the following components in percentage by weight: 20% to 25% of inorganic acid, 10% to 20% of organic acid, 10% to 18% of surfactant, 8% to 15% of osmotic agent, 6% to 18% of emulsifier, 2% to 8% of antifoaming agent, 5% to 8% of complexing agent, and 25% to 30% of water. In the provided cleaning agent, the using amount of hydrochloric acid, sulfuric acid, and nitric acid is reduced, the aluminum parts are washed by medium-strong acids and organic acids, and the cleaning agent has a very good oil stain and rust removing ability. The cleaning agent is acidic, the pH value of the cleaning agent is 2.1 to 5.6, and the cleaning agent can well remove the oxide scale on the aluminum surface. Because the acidity of the organic acids is weak, the over-corrosion on work tools and acid volatilization, which can harm the workers' health, are effectively avoided, and the cleaning effect is not influenced at the same time. Moreover the adopted organic acids are easy to decompose, and thus the cleaning agent is environment-friendly.
