Nowadays, after continuous research by professionals, there are more and more types of radiant tubes. They come in various shapes, such as U-shaped, W-shaped, trident-shaped, etc. There are many types, but they all have different shapes. Each has its own advantages, which are briefly introduced below.1. Installation, testing and maintenance are convenient and are all done outside the furnace.There is no need to shut down the furnace or cool down the furnace temperature to repair and replace the electric heating device.Under normal production conditions, replacement only takes about 10 minutes, which greatly reduces labor intensity and improves productivity.2. Compact structure, stable performance, high single power, and service life several times that of ordinary electric heating tubes.

The radiant tube is the key equipment in the heating section of the continuous annealing furnace of the galvanizing unit. It is used to radiate the strip steel, eliminate the internal stress of the strip steel, improve the plasticity, and achieve the purpose of annealing. However, if the radiant tube leaks, it will cause great harm to the production and operation of the unit. The consequences may even affect the normal operation of production.To prevent the radiant tubes from being burned and to extend the service life of the radiant tubes, certain measures need to be taken.1. Adjust the combustion ratio of combustion gas and combustion-supporting air. In a nitrogen-protected atmosphere, excess oxygen will undergo strong nitriding and oxidation, causing the radiant tube to be corroded and damaged, so the O2% content in the combustion exhaust gas is controlled below 2%. .2. The gas pressure control valve and air pressure control valve should be sensitive in action without lag, to ensure the stability of gas pressure and air pressure during combustion and to ensure complete combustion of gas.3. The exhaust fan rotates smoothly to reduce the fluctuation of the combustion flame.4. The heat exchanger of the combustion air must not leak to prevent the air from being blown by the exhaust gas.

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

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.
