Thin belt continuous casting crystal roller surface electroplating method and electroplate liquid thereof

Abstract

The invention relates to a surface processing method and the processing liquid of a successive casting roller, more particularly, relates to the electric plating method and the electric plating liquid to the surface of a thin belt successive casting crystallizing roller. The electric plating method mainly aims at solving the technical problems that the thickness of the plated layer obtained with the prior method is not even enough and the overall property of the plated layer is slightly inadequate. The electric plating method in the invention comprises two steps namely preprocessing before plating operation and electric plating operation of a metallic nickel. During the step of preprocessing before plating operation on the surface of the successive casting crystallizing roller, the step includes the following operations: organic solvent cleaning, alkali degreasing, electrolytic degreasing, acid etch and activatory process. Within the step of electric plating operation of a metallic nickel, the components of the electric plating liquid consists of nickel sulfamic acid Ni (NH2SO3)2.4H2O 250 to 380gs per l, nickelous chloride NiCl2.6H2O 8 to 15gs per l, boric acid H3BO3 25 to 40gs per l and dodecyl sodium sulfate CH3(CH2)10CH2OSO3Na 0.05 to 0.1gs per l. when in electric plating operation, the electric current density within the original 4 to 12 minutes is 0.5 to 2.0A per dm2, the electric current density in normal electric plating operation is 1.0 to 5.0A per dm2 and the rotating speed of a roller is 2 to 7 cycles per minute. The obtained metallic nickel plated layer has strong intensity with the substrate and further has the advantages of low stress, even thickness, fine flexibility, friction bearable, excellent cold and hot resistant and antifatigue properties.

Benefits of technology

This patented technology allows for better control over how well an aluminum sheet cast has been made from molten steel without causing cracks or flaws when it comes into contact with another material like water. It also includes various techniques such as applying special coatings onto the surfaces beforehand, create specific layers within them (such as adding lubricants), controlling coolant flow rates through the rollers themselves, and optimizing electrical pulse waveforms used to improve energy utilities. Overall, this innovation helps make producing high-quality thin strips faster while maintaining their longer lifespan compared to traditional methods.

Problems solved by technology

Technological Problem: The present invention relates to a new way to produce thin sheets (metal) without damaging their surfaces during manufacturing processes such as electric arc welded blades. Current methods involve multiple steps involving various materials like aluminum alloys, stainless steels, titanium nitride coatings, ceramics, and other similar materials. These techniques require expensive tools and long periods of operation before they become effective overcomes issues related to these conventional ways.
