Graphite mold for continuous casting

Continuous casting graphite mold refers to graphite products used in continuous casting molds. Metal continuous casting technology is a new technology that directly turns molten metal into a material through a continuous casting mold. Because it does not undergo rolling and becomes a material directly, the secondary heating of the metal is avoided, so a lot of energy can be saved.

Continuous casting graphite is made from carbonaceous raw materials (petroleum coke, pitch coke, coal pitch…) after a series of production processes. Among them, the compression molding process can be respectively cold compression molding or cold isostatic pressing molding process. The advanced high-tonnage cold isostatic pressing process is adopted to ensure the production of uniform, dense and high-strength continuous casting graphite. Increasing the surface coating technology treatment can sing the service life of the graphite crystallizer, improve the quality of the continuous casting metal surface, and increase the continuous casting process speed.

Compared with graphite materials for other purposes, continuous cast graphite has the following characteristics: fine particles, uniform texture, high volume density, low porosity and high strength. Its basic performance is as follows:

Overview of the development of continuous casting graphite at home and abroad

1) Countries attach great importance to the development and application of continuous casting graphite. This can be confirmed from the increase in the variety of continuous casting graphite, process improvement, and quality improvement. For example, Germany and Japan dare to spend a lot of money in the process of developing continuous casting graphite, so they produce more varieties of continuous casting graphite, and the quality is also better. Copper profiles and cast iron continuous casting technology are also relatively developed.

2) In the direction of product development, foreign countries have paid more attention to the development of fine-grained, high-density, isotropic graphite as continuous casting graphite. In particular, the German Linsdorf company has accumulated considerable experience in this area and has taken many measures. Japan’s Toyo Tansuo Company has also been catching up, and it has the potential to surpass. In China, Dongshin Electric Carbon Plant and Shanghai Carbon Plant have been successful in this area a few years ago. In order to improve the performance of the working surface of the graphite crystallizer, the surface coating technology is adopted, which has a greater effect on the improvement of the service life of the continuous casting graphite. The Soviet Union adopted boron nitride coating technology, while the coating of continuous cast graphite in my country is mainly deposited pyrolytic graphite. Although it has not been widely popularized, it has been welcomed by many users. In addition, the Shanghai Electric Carbon Plant also uses the traditional formula to add 0.6 to 2% of metal oxides, and uses the mechanism of these metal oxides to convert into high melting point carbides at 2500 ℃ graphitization high temperature, thereby improving the oxidation resistance of continuous casting graphite. To achieve the purpose of improving the service life.

3) The large-scale specification of continuous casting graphite has become a top priority. In view of the fact that the quality of large-scale continuous casting graphite has a large gap compared with foreign countries, great efforts should be made to develop it. This is worthy of the relevant manufacturers’ attention, both in terms of social and economic benefits.

4) In my country, the continuous casting technology of copper profiles has developed rapidly, started earlier, has a larger scale, and has more mature and rich experience. The continuous casting technology of continuous casting profiles is newly developed, and the continuous casting technology required Although cast graphite can still be used, further improvement and improvement are necessary.

5) Research should be carried out to improve the machining accuracy of the continuous casting graphite mold and improve the product structure. This is also one of the measures to improve the life of the graphite crystallizer. Germany and the Soviet Union have clear requirements for product machining accuracy, and domestic users also hope that the roughness of the inner wall of continuous casting graphite can be improved, which can effectively prevent cracks on the surface of the casting. In addition, in order to improve the contact state. The shape and structure of continuous casting graphite should be improved so that the contact area between it and the copper mold reaches 80%.
