    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

    Denitrification and desulfurization pressure vessels are a common type of pressure vessels and are mostly used in thermal power plants.Many people want to know how it is used in thermal power plants.Well, our company is a manufacturer that has specialized in producing denitrification and desulfurization pressure vessels. Below, our company will give you a brief explanation.First of all, we have all seen the pressure vessel. It is a large-scale sealed device that contains gas or liquid and can withstand a certain pressure.Generally, storage and transportation vessels, reaction vessels, heat exchange vessels and separation vessels are pressure vessels.As you all know, in thermal power plants, power generation in thermal power plants will produce a large amount of waste gas containing sulfur and nitrate from the burning coal. When these waste gases are discharged into the atmosphere, they will cause pollution and form acid rain.Therefore, of course, these wastes cannot be discharged directly into the air, so they can only be processed in containers, and this container device is a denitrification and desulfurization pressure vessel.There are many methods for desulfurization and denitrification processes. You can also go online to find answers.

    With the continuous development and innovation of science and technology, new equipment and new technologies have been applied in many industry fields.This improvement made up for the shortcomings of many devices that could not be used because some factors could not meet customer needs, so many emerging products and devices came out.The same is true in pressure vessel equipment. The materials used are also very different due to different uses. In addition to the common ones we have, there are also some special materials that are also popular for pressure vessel equipment.

    Pressure vessels are used in a wide range of applications around us, and there are many types.Generally speaking, there are storage tanks, oil pipes, buffer tanks, etc. Depending on the material, there are also stainless steel pressure vessels, titanium pressure vessels, etc.In terms of use, they are divided into pneumatic tools, vehicle braking, textile machinery, mining, etc., and of course there are also small pressure vessels, high pressure pressure vessels, etc.The stainless steel pressure vessels produced by our company (heated by electricity, steam, thermal oil) are composed of pot lid, barrel body, jacket, agitator, shaft seal transmission device and support. The pot body and parts in contact with the materials in the pot All made of 304 or 316 stainless steel.Due to different production processes, operating conditions, etc., users can use jackets, half pipes, coils, Miller plates and other structures for heating and cooling. Jacket heating types are divided into electric heating rod heating, steam heating, thermal oil circulation heating, and shaft heating. Sealing devices are divided into packing seals and mechanical seals. The mixing types generally include anchor type, paddle type,
