CuCrZr Copper Rectangular Tube 135mm Con Cast Machine Ccm Mould Tube

Copper mould tube is one of the core equipments of ccm continuous billet caster. It makes high temperature liquid steel solidify and crystallize rapidly to form steel castings. After electromagnetic induction stirring, the liquid steel in the copper mould is cooled and shaped, and then the casting is pulled out, and then the slab is divided into predetermined length by flame cutting machine ( Torch Cutting Machine).The molten steel is directly cast in the mold copper tube, and the steel billet is continuously cooled and formed in the copper tube. In order to solve the problem that the copper tube is in contact with the cooled billet shell and separated from time to time during the working process, the mold copper tube is still bent to one side Square or rectangular copper tube, the inner cavity of the copper tube is tapered from the upper mouth to the lower mouth, and the inner cavity of the copper tube is a double-cone or tri-cone or multi-cone, or a parabolic cavity from the upper mouth to the lower mouth. Shape, the taper of the upper section or the upper part is greater than the taper of the lower section or the lower part. It is best that the taper of the straight surface is greater than the taper of the curved surface. Avoid the air gap between the blank shell and the inner wall of the copper tube during the working process, which is more in line with the contraction change law of the blank shell.

The role of mold copper pipe is very wide, and it plays an extremely important role in industrial manufacturing. For example, mold copper pipe is used in the manufacture of ships, ships, automobiles and refrigerators. Main characteristics of high efficiency continuous casting mold copper pipe material: high efficiency continuous casting mold material has good thermal conductivity, high recrystallization temperature, thermal fatigue resistance, high strength, good wear resistance and long service life. The main characteristics of high efficiency continuous casting mold copper pipe material are that the comprehensive performance of the above properties of copper pipe material is the best.
Characteristics of explosion formed mold copper pipe: mold copper pipe with taper can be manufactured by profiling processing or pressure forming method with inner core and outer mold. Profiling processing will destroy the organizational structure of copper and affect the service life. Processing complex taper requires special processing equipment and improves the manufacturing cost. Pressure forming will produce large head and tail cutting, and the yield of copper is low. The explosion formed mold copper tube can be made into multi taper and small corner of the inner cavity, which is especially conducive to the repair of the scrapped old mold.

In order to improve the wear resistance of chromium coating and prolong the service life of mold copper pipe, 0.4-0.5mm thick nickel cobalt alloy coating is added between the inner surface of mold copper pipe and chromium coating as a transition layer. Therefore, it is called nickel cobalt alloy hard chromium coating. Composite copper plated pipe for short. The metal content is: the hardness of the coating is 300-600hv.
Nickel cobalt alloy coating has good chemical corrosion resistance, thermal corrosion resistance and wear resistance. It not only blocks the diffusion of Zn, s, CD and F in molten steel to the inner surface of the mold copper tube, but also acts as a binder between the inner surface of the mold copper tube and the chromium plating layer, which greatly improves the wear resistance of the chromium plating layer. In addition, after the chromium plating layer is worn, the nickel cobalt alloy coating can continue to work instead of the chromium plating layer, so as to prolong the service life of the mold copper pipe.
Through the above introduction to mold copper pipe, I believe you have fully understood the products and characteristics of mold copper pipe. The function and function of crystalline copper pipe are great. Although you may disagree and think it is a little far away from you and your family, mastering a normal product knowledge is conducive to your further and broader development! Only by constantly enriching their knowledge can they obtain a wider understanding, especially for young people, and constantly meet the needs of society.
