The "2008 National Chemical Heat Exchanger Technology and Equipment Exchange Conference," organized by China Chemical News and supported by the China Pressure Vessel Society Heat Exchanger Committee, will take place in Jiujiang, Jiangxi Province from April 8th to 11th this year. This event is expected to bring together industry professionals, researchers, and manufacturers to discuss advancements and innovations in heat exchanger technology.
As a key sector that both produces energy and consumes significant amounts of it, the oil and chemical industry plays a crucial role in national energy strategy. According to recent calculations, the seven major energy-intensive industries within the petrochemical sector—refining, ethylene production, synthetic ammonia, caustic soda, calcium carbide, soda ash, and yellow phosphorus—have an estimated energy-saving potential of over 15 million tons of standard coal. Improving the efficiency of technical equipment, especially heat exchangers, is one of the most effective ways to achieve these savings.
Heat exchangers are essential components in the production processes of the petroleum and chemical industries. With the rapid expansion of China’s petrochemical and steel sectors, demand for advanced heat exchangers has surged, and so have the expectations for their energy efficiency. Many universities, research institutions, and companies have made significant progress in developing and applying heat exchanger technologies, achieving notable results.
This conference aims to provide a platform for sharing the latest achievements and practical experiences in heat exchanger technology, both domestically and internationally. It will facilitate knowledge exchange, foster collaboration, and support the application of new technologies by users and manufacturers alike. By promoting the industrialization of scientific research outcomes, the event hopes to drive sustainable development and technological advancement in the chemical industry.
Investment Casting Lost Wax Casting
Investment casting, which is also known lost wax casting or precision casting, refers to the formation of ceramic around the wax patterns to create a multi or single part mold to receive molten metal. This process utilizes an expendable injection molded wax pattern process to achieve complex forms with exceptional surface qualities. To create a mold, a wax pattern, or cluster of patterns, is dipped into ceramic material several times to build a thick shell. Die-wax process is then followed by the shell dry process. The wax-less ceramic shell is then produced. Molten metal is then poured into the ceramic shell cavities or cluster, and once solid and cooled, the ceramic shell is broken off to reveal the final cast metal object. Investment castings can achieve exceptional accuracy for both small and large castings in a wide range of materials.
