Energy Saving Technology of Tube Heating Furnace With the development of industrialization, petroleum, as an important form of energy, drives the development of the entire petrochemical industry such as petroleum refining and petrochemical industry. So far, the petrochemical industry has been a pivotal sector in the world economy. In these industries, the main process medium heating furnace currently used is the tube furnace, which has the following main characteristics.Vacuum heat treatment of electrical pure iron Due to the flow in the tube, the heated medium is limited to gas and liquid. Usually these gases or liquids are usually flammable and explosive substances, which are relatively dangerous and the operating conditions are relatively harsh. The heating method is mainly direct type, the fuel is liquid or gas, the operation period is long, and the operation is continuous and uninterrupted.Effect of Vacuum Annealing on Properties of 304 Stainless Steel Tensile Billets Heap furnace, which refers to the principle of kettle steamer. The heat-absorbing surface is a group of tube bundles, and the connecting elbows between the tubes are also placed in the furnace. Since the burner is directly installed under the tube bundle, the heating intensity of each row of tubes in the furnace is uneven. When the bottom row of tubes is heated as high as 50000~70000kcal/m2·h, but the top row of pipes is less than 800~1000cal/m2·h, so the bottom row of pipes is often burned through, and the joints between the pipes are easy to loose and leak, causing fires.Z3132 RADIAL DRILLING MACHINE The pure convection furnace was considered to be because the radiant heat was too strong, so it was changed to a pure convection furnace. All the furnace tubes are installed in the convection chamber, and the convection chamber is separated from the combustion chamber by a partition wall to prevent the furnace tube from being directly scoured by the flame. However, during the operation, it was found that the top row tubes of the convection chamber were often burned out, and the heating of the furnace tubes was still very uneven. This is because the high-temperature combustion flue gas fails to exchange heat with a heat-absorbing surface before entering the convection chamber, and the temperature at the entrance of the convection chamber is as high as 1000 °C.Z3032 RADIAL DRILLING MACHINE

The combustion chamber is composed of two adjacent vertical fire channels, one is the updraft and the other is the downdraft. Its gas flow is, type. This combination of fire paths is called double fire paths.Vacuum heat treatment of corrugated spring bayonet connector There is a regenerator in the lower part of each carbonization chamber. The regenerator is composed of a group of two-part types along the length of the carbonization chamber. The regenerators arranged in this way are called front and rear arrangements.Analysis of carbon content on the surface of carburized parts When heating with blast furnace gas, the blast furnace gas is preheated by the coke side (coke quenching car side) waste gas valve to the regenerator, and the air is also preheated in the same way, which is preheated from the coke side air valve to the adjacent regenerator. The blast furnace gas and air in the coke side fire channel are directly transported to the vertical fire channel from the regenerator. The blast furnace gas and air in the fire channel on the machine side are transported from the regenerator to the vertical fire channel through the horizontal flue.HORIZONTAL MITRE BAND SAW MACHINE BS-315GH On the contrary, the coke-side exhaust gas passes through the horizontal flue and enters the machine-side regenerator, and the machine-side exhaust gas directly enters the machine-side regenerator. From a regenerator, the half of the coke side is the updraft, and the half of the machine side is the downdraft.SISSOR TYPE HORIZONTAL MITER CUTTING BANDSAW BS-280G

Heating principle of electric furnace for foundry The electromagnetic induction heating intermediate frequency melting furnace currently popular in electric furnaces for foundry can heat and melt scrap metal materials such as iron and steel, aluminum, copper, gold, silver, etc., add alloy components, and pass through slag removal and other processes to become qualified metal liquids and cast to form castings. It has the characteristics of quick start, high heating efficiency, electromagnetic stirring, instant use and low energy environmental protection. It is the preferred heating equipment for electric furnaces in the foundry industry.Application of low pressure vacuum carburizing Heating principle of electric furnace for foundry:This electric furnace for handcuffs is a non-vacuum metal heating and smelting equipment, without gas break protection components, adding scrap metal into the casting furnace, at this time, the intermediate frequency power supply and the smelting furnace money ring are combined to generate a magnetic field in the coil, so as to create a magnetic field inside the technology. The eddy current generates self-heating, and the electric casting furnace will complete the process of heating and heat preservation according to the given temperature curve, and then transport all the metal liquid out of the furnace, and pour it into the mold to become a casting after cooling.Analysis of carbon content on the surface of carburized parts The composition of the electric furnace for casting: the melting system of the electric furnace for casting generally consists of a transformer, a low-voltage cabinet, an intermediate frequency power supply, a steel shell furnace body, a hydraulic tilting furnace system, a leakage furnace protection system, a cooling circulation system, a magnetic yoke, a capacitor bank, a water-cooled cable and feeding materials. car etc.Vacuum heat treatment of corrugated spring bayonet connector

Introduction of VOD Ladle Refining Furnace Technology VOD type vacuum refining equipment is one of the most widely used out-of-furnace refining equipment in the world. It has many advantages such as simple equipment, low investment, low cost, many types of refined steel, high quality and convenient operation, so it has become an essential refining method for special steel plants.Deformation and Control of Carburizing and Quenching for Large Gears and Gear Shafts VOD ladle refining furnace has many functions such as vacuum degassing, oxygen blowing decarburization, vacuum feeding, argon blowing stirring, non-vacuum temperature measurement and sampling, wire feeding and so on. It can refine bearing steel, alloy structural steel, spring steel, high-quality carbon steel and ultra-low carbon stainless steel.Reaction sintering of silicon carbide ceramics Because of its strong vacuum degassing ability, it can ensure that the content of hydrogen, oxygen, nitrogen and carbon in the steel reaches the lowest level, and accurately adjust the composition of molten steel, so that the inclusions can be fully floated, and the cleanliness of the steel can be effectively improved. Because it refines many types of steel and high quality, it can more flexibly adapt to the needs of market competition for users, and can refine the steel types required by the market in time, thereby increasing the economic benefits of the enterprise.Vacuum heat treatment of corrugated spring bayonet connector
