Copper Mould Tubes & Plates
제품설명
With dedicated to research of new technologies, we continuously developed various sizes,materials and special shapes, large and super large size mould tubes. We also developed various types of high efficiency copper mould tube for continuous casting machine. Our products range also features mould assembly and other metallurgical spare parts. Apart from copper mould tubes, we also produce various types of copper mould plates and assembled beam blank moulds.

• Reduced billet rhomboidity
• Improved billet shape
• Better internal billet and slab quality
• More uniform shell growth
• Less „snaking“ of the billet
• Longer mould life
The copper mould tube is the core component of continuous casting. The copper plate of the copper mould tube is an important heat-conducting component in continuous casting from liquid steel to solidification into a solid shell. Its quality directly affects the surface quality of the slab, the casting speed and other indicators. The molten steel flows through the copper plate of the copper mould tube, copper mould tubes into a billet under the action of external cooling water, and is pulled out of the copper mould tube by the dummy rod. Frequent billet drawing causes serious wear and tear on the copper plate of the copper mould tube, and frequent replacement not only reduces production efficiency, but also consumes a large amount of copper mould tubes. In order to improve the service life of the copper mould tube copper plate, relevant domestic and foreign units and experts have conducted long-term and in-depth research on copper plate materials and coatings, and have achieved great results. At present, thermal analysis technology has begun to be applied at home and abroad to study the optimization of copper mould tube design and coating selection. The application of thermal analysis technology on the copper mould tube copper plate has greatly improved the life of the copper mould tube plate.
Nickel Chromium Cobalt Coating
Copper has lower hardness which leads to lower anti-abrasive property. Therefore, the area at the lower part of the moulds, where the stress increases drastically due to shells, will be more severelyworn. To increase the life time of copper moulds, MY provides uniform mould interior surface plating with suitable hardness. Most of the copper mould tubes for small size billet casting are not used in any casting system where there are rigid casting stream support, therefore they are very sensitive to be worn. We use hard chrome plating to increase the life of mould tubes. The plating thickness recommended by MY will be controlled in the best range. As for the coating of copper mould plates, based on our years of experience, we are able to provide Cr coating, Ni-Cr coating, Ni-Fe coating and NiCo-Cr coating to meet the demand of various customers both at home and abroad.
