The selection of graphite material for graphite crystallizers needs to be customized according to the different copper materials. For example, we can develop graphite materials for different copper materials such as copper, brass, bronze and white copper. Such a targeted selection of materials not only optimizes the performance of the graphite crystallizer, but also improves its cost-effectiveness.
Product Processing
Graphite crystallizers are subject to extremely tight dimensional tolerances, surface smoothness and flatness. Our graphite crystallizers ensure that the working surfaces have a mirror finish and that all dimensions are in accordance with the drawings. For graphite crystallizers used in the production of copper alloys, we can purify, impregnate with oxidation-resistant and pyrolytic carbon coatings to improve their effectiveness and extend their service life.
Introduction to the Continuous Casting Process
The continuous casting process is widely used for the production of semi-finished products of copper and other non-ferrous alloys. During continuous casting, liquid metal is continuously poured into a mold, solidified in a wire shell inside the mold, and then pulled out downward, sideways or upward. Continuous casting crystallizers are divided into horizontal continuous casting crystallizers and up-directed mold continuous casting crystallizers.
Our graphite crystallizers have excellent thermal conductivity, chemical and heat resistance and high strength. Factors such as the finish of the inner surface of the crystallizer, the dimensional accuracy and the tolerance of the gap after assembly will affect the surface effect of the drawn copper or the frequency of use of the crystallizer. We have several CNC machining centers and coordinate inspection equipment to ensure that accuracy requirements are met.
Importance of Continuous Casting Mold
Continuous casting crystallizer is a key component of continuous casting equipment, and the material used for processing continuous casting crystallizer is directly related to the effectiveness of metal continuous casting technology. Graphite material is the ideal material for processing continuous casting crystallizer because of its high temperature resistance, oxidation resistance, chemical erosion resistance, self-lubricating and good thermal conductivity and other characteristics. In addition to the above characteristics, graphite material for continuous casting crystallizer should also meet the requirements of high density, high strength, uniform structure and good thermal shock resistance.
Applications
Graphite crystallizer has been widely used in the continuous casting of copper alloys (bronze, brass, nickel-copper) and aluminum alloys, and is gradually being promoted for the continuous casting of steel. Compared with graphite materials for other applications, continuous casting graphite is characterized by fine grains, uniform texture, high bulk density, low porosity and high strength.
