Industry trends

The role of the ring furnace in the production line of hot rolled seamless steel tubes is to heat the qualified sized tube blanks after sawing the tube blanks from normal temperature (20 ℃) to 1280 ± 5 ℃ for the piercing unit to carry out the piercing process. The ring furnace is an ideal industrial furnace type for heating round billets in the world at present. The annular furnace is a highly mechanized furnace that moves the billets placed on the furnace bottom from the charging port to the discharging port in the furnace by means of the furnace bottom drive. The middle passes through the preheating section, and the heating section and soaking section heat the tube blank to the required rolling temperature. The ignition sequence of the annular furnace: first supply fire → gas → air → adjust the proportion of air and gas. Shutdown sequence

Sewage comes from domestic and industrial production, which contains a variety of pollutants with complex composition, leading to very troublesome treatment. The disposal and storage of sewage has become a difficult problem. Domestic sewage, rainwater, microorganisms and chloride ions will also corrode reinforced concrete. The pollutants in industrial wastewater are more serious, containing a large number of chemical substances and waste particles, and having strong corrosivity. The inner wall and bottom of the sewage pool are often affected by sewage erosion, abrasion of solid particles, microbial corrosion and the aging of reinforced concrete structures, resulting in cracks and leakage, environmental pollution and production safety problems. For this reason, pollution

In summer, there is direct sunlight and high temperature. The building roof has a high heat absorption rate. High temperature heat conduction leads to stuffy buildings, including buildings, factory buildings, grain depots, machine rooms and oil tanks. The sunscreen and heat insulation coating has been used outdoors for a long time, and it is anti-aging, non yellowing, self-cleaning and clean, with a service life of 15 years. Sunscreen and heat insulation coating is applied on the surface of buildings, including buildings, workshops, grain depots, oil tanks and other buildings to insulate heat, reduce the surface temperature of objects after sun irradiation. 221 Sunscreen and heat insulation coating can reduce the surface temperature of objects by more than 20 degrees Celsius, with remarkable heat insulation effect. If the energy conservation and emission reduction of buildings are achieved, it is also a

Refractory Ceramic Waterproof Coating Anticorrosive rigid flexible refractory material characteristics determine the complexity, variability and dispersion of its mechanical properties. In addition, the difference in the nature and mix proportion of refractory raw materials makes it difficult to study the mechanical properties of refractory materials from microscopic quantitative theoretical analysis. ZS-933 ceramic waterproof and anticorrosive coating developed and produced by Zhisheng Weihua Group is an inorganic modified waterproof and anticorrosive coating with a temperature resistance of 1800 ℃. ZS-933 waterproof and anticorrosive coating is thin, high hardness, smooth and full coating, good weather resistance and flame retardancy, unidirectional air permeability, high self-cleaning, and long time

How to prevent corrosion of coking equipment pipeline in coal chemical industry Coking in coal chemical industry refers to the technological process in which coking coal is heated to about 1000 ℃ (high temperature carbonization) under air isolation conditions, and coke, coke oven gas and coking chemicals are produced through thermal decomposition and coking. Recovery of coal tar, benzene, ammonia, sulfur and other by-products from coke oven gas not only brings huge profits to enterprises, but also purifies gas. However, these coking processes of coal chemical industry also have great side effects, and one of the more important reasons related to the self interests and safety of coking enterprises of coal chemical industry is the serious corrosion of equipment. Corrosion encountered in coal chemical coking industry

The sewage treatment plant generally adopts open or semi closed sewage pool, which will increase the humidity of the plant area. Both the equipment exposed to the atmosphere and the water immersion equipment are facing more severe corrosion than the conventional atmospheric environment. According to the ISO-12944 standard, the sewage treatment plant can be classified as C5 corrosion environment. No matter whether the sewage pool is of concrete or carbon steel stainless steel structure, it will face the alternative corrosion of multiphase media, mixed acid and alkali, and various chemicals, which reflects the corrosion characteristics of the sewage pool as "change". "change" is reflected in the uncertainty of sewage source, the uncertainty of the amount of chemicals added
