We all know that a pressure vessel is a very powerful piece of equipment and is generally a large piece of equipment.It mainly refers to a closed device that contains gas or liquid and carries a certain pressure.Therefore, there will be a large number of applications in pharmaceutical, petrochemical, food, scientific research and other fields.So how many manufacturing processes does this type of pressure vessel generally have?The manufacturing process of pressure vessels can generally be divided into: raw material acceptance process, scribing process, cutting process, rust removal process, machining (including planing, etc.) process, rolling process, assembly process, and welding process (product welding test plate) , non-destructive testing process, hole opening and scribing process, general inspection process, heat treatment process, pressure test process, anti-corrosion process.

Many people may not know what a hearth roller is, and it is normal to not know it because they have little contact with it.This type of equipment is very important in the modern industrial development of our country, because our country's heat treatment technology is now widely used, not only in the industrial field, but also in the metallurgical industry and the steel industry, and the furnace bottom The roller is a very critical piece of equipment in the heat treatment technology.

The performance of the furnace roller is: 1. The quality of the furnace roller of the silicon steel continuous annealing furnace is one of the main factors affecting the operation rate and product surface quality. The traditional graphite carbon sleeve and ceramic coated roller are prone to roller surface oxidation and roller nodulation. , loosening and peeling, etc., affecting normal production.2. Quartz ceramic hollow rollers have the characteristics of high strength, high temperature resistance, small thermal expansion, good chemical stability, stable high temperature performance, no deformation, smooth and delicate surface, and good wear resistance. They are the superior features of traditional graphite carbon sleeves and ceramic coated rollers. Ideal replacement product.It can effectively solve the problems of oxidation and nodulation, avoid frequent replacement operations, improve operating efficiency, and significantly improve the surface quality of the steel strip.3. It is not easy to wear after long-term use, and the service life is 3-5 times that of the carbon sleeve. The used old roller can be used repeatedly after being reprocessed, which greatly extends the service life and reduces production costs.4. The operating temperature is as high as 1100°C, especially suitable for continuous annealing furnaces of high-grade silicon steel.5. Adopt this
