Embodiment 1
[0007] Example 1: Heating the central part of the roll neck at 600°C, and after heating for 2 hours, treating the outer edge of the roll neck with a surface treatment agent, and treating the outer edge of the roll neck: first, surface treatment Spread the agent evenly on the outer edge of the roll neck, then assemble the roll neck and the roll body and place them in a vibrator to fix them and shake them at 700r / m for 3 minutes, and finally heat the end of the roll body surface near the roll neck at 650°C The surface treatment agent includes 5g / L polyethylene glycol, 1g / L titanium sulfate, 8g / L phosphoric acid, 20g / L sodium metavanadate, 8g / L tartaric acid, 11g / L malic acid, 4g / L ammonium fluoride , 6g / L p-tungstic acid, 13g / L zirconium lactate.
Embodiment 2
[0008] Example 2: Heating the central part of the roll neck at 700°C, and treating the outer edge of the roll neck with a surface treatment agent after heating for 3 hours, and treating the outer edge of the roll neck: first, surface treatment Spread the agent evenly on the outer edge of the roll neck, then assemble the roll neck and the roll body and place it in a vibrator to fix it and shake it at 700r / m for 5 minutes, and finally heat the end of the roll body surface near the roll neck at 550°C The surface treatment agent includes 30g / L polyethylene glycol, 5g / L titanium sulfate, 2g / L phosphoric acid, 1g / L sodium metavanadate, 2g / L tartaric acid, 4g / L malic acid, 15g / L ammonium fluoride , 1g / L p-tungstic acid, 7g / L zirconium lactate.
Embodiment 3
[0009] Example 3: Heating the central part of the roll neck at 650°C, and treating the outer edge of the roll neck with a surface treatment agent after heating for 3 hours, and treating the outer edge of the roll neck: first, surface treatment Spread the agent evenly on the outer edge of the roll neck, then assemble the roll neck and the roll body and place it in a vibrator to fix it and shake it at 700r / m for 4 minutes, and finally heat the end of the roll body surface near the roll neck at 650°C The surface treatment agent includes 13g / L polyethylene glycol, 2g / L titanium sulfate, 4g / L phosphoric acid, 16g / L sodium metavanadate, 6g / L tartaric acid, 7g / L malic acid, 10g / L ammonium fluoride , 5g / L p-tungstic acid, 8g / L zirconium lactate.

Abstract
The invention discloses a treatment method of a roller neck surface. The method includes the specific steps that the center portion of a roller neck is heated at the temperature ranging from 600 DEG C to 700 DEG C, after the center portion is heated, the temperature is kept for 2 to 3 hours, and the outer edge portion of the roller neck is treated through a surface treating agent; and the outer edge portion of the roller neck is treated in the process that firstly, the outer edge of the roller neck is evenly coated with the surface treating agent, the roller neck and a roller body are assembled and placed in a vibrator to be fixed and then shake for 3 minutes to 5 minutes at 700 r / m, and finally the end, close to the roller neck, of the surface of the roller body is heated at the temperature ranging from 550 DEG C to 650 DEG C, wherein the surface treating agent comprises 5 g / L to 30 g / L of polyethylene glycol, 1 g / L to 5 g / L of titanium sulfate, 2 g / L to 8 g / L of phosphoric acid, 1 g / L to 20 g / L of sodium metavanadate, 2 g / L to 8 g / L of tartaric acid, 4 g / L to 11 g / L of malic acid, 4 g / L to 15 g / L of ammonium fluoride, 1 g / L to 6 g / L tungstic acid and 7 g / L to 13 g / L of lactic acid zirconium. By the adoption of the method, a roller is resistant to abrasion and corrosion and is provided with the surface with the good tensile property, it is guaranteed that the connection performance of the roller neck and the roller body is stable, shake is reduced, the noise is low in the rolling process, the rolled product quality is guaranteed, and the safety of the production process is guaranteed as well.
Description
technical field [0001] The invention relates to a treatment method for the roll neck surface. Background technique [0002] The rolling mill uses the pressure generated when the roll rolls to roll the rolled material and make the metal of the rolled material plastic. The roll is an important consumable part that determines the efficiency of the rolling mill and the quality of the rolled material. The roll includes the roll head, roll neck and roll body. In order to increase the The surface strength of the roll neck can be improved to prevent the roll neck from breaking during operation. In the prior art, the roll neck surface will be treated. Although these treatment methods can prevent the roll neck from breaking at the center, the treatment effect on the joint between the roll neck and the roll body is average, and the long-term Time adopts the processed roll in the prior art, and the roll will produce jumping, which affects the rolling accuracy, and even disconnects the c...
