The elliptical head belongs to the type of heating furnace component in the high-pressure vessel. The medium-frequency induction heating method is used to locally heat the water pipe, and gear transmission and bending can be performed at the same time. The output power can reach 120KW, and water pipes of various sizes and models can be heated. It heats quickly, the output power can be infinitely adjusted, the starting characteristics are good, the characteristics are stable, the footprint is small, and it is convenient in actual operation and maintenance. The elliptical head is a component of the container. According to its geometric shape, it can be divided into several types such as sphere, ellipse, disc, spherical crown, conical shell friendship cover, etc. Among them, spherical elliptical head, elliptical head, disc elliptical head, and spherical crown elliptical head are collectively referred to as convex elliptical heads. It is suitable for various appliances and mechanical equipment, such as storage tanks, heat exchangers, towers, reaction tanks, heating furnaces, separation equipment, etc.

The elliptical head is composed of a rotating elliptical sphere and a cylindrical straight section. It is used on high-pressure vessels, with a head on each side and a connecting pipe section in the middle, which serves as the bottle of the high-pressure vessel. The elliptical head with a rotating elliptical spherical busbar long-short axis ratio of 2.0 is usually called a standard elliptical head. The physical properties of the elliptical head are only lower than those of the hemispherical head, but better than those of the dished head. Since the deep layer of the elliptical head is located between the hemispherical head and the dished head, the regulations and manufacturing difficulty coefficient of the stamping machinery and mold shell are also between the two, which is much easier than the hemispherical head and much more difficult than the dished head. In recent years, the application of stamping manufacturing technology has made the manufacture of large-caliber elliptical heads convenient. Elliptical heads are widely used in medium and low pressure vessels due to their good comprehensive performance.

Elliptical heads are widely used in crude oil, electronic devices, chemical plants, pharmaceuticals, textile industry, food, machinery and equipment, engineering construction, nuclear power plants, aerospace, military industry and other fields. The application of elliptical heads in industry is very extensive. Whether in light industry or industry, the application of elliptical heads is ubiquitous. In the entire design of the elliptical head, the first thing to be satisfied is strength, followed by rigidity. In these two aspects, to effectively meet the standards, it is necessary to minimize its own weight and save the use of metal as much as possible. But in the entire structure, it is necessary to emphasize simple and beautiful design. In addition, it is easy to manufacture and produce, ensuring that each component installed on the equipment can be easily installed, repaired and adjusted. In terms of structural design, another thing to pay attention to is the reduction of noise and vibration in the future.
