Aging furnace heating principle The aging furnace is a common heating equipment. Its principle is to use electrical energy or fuel energy to convert thermal energy into the heat of an object. Aging furnaces are widely used in industrial production, especially in the heat treatment process of metal materials, which play an important role.Sintering process of silicon nitride ceramics The heating principles of aging furnaces mainly include conduction, convection and radiation. First of all, conduction refers to the transfer of heat through the molecules inside an object, causing the object to heat up as a whole. When the heating element (such as resistance wire or burner) in the aging furnace is supplied with electrical energy or fuel, it will generate high temperature. By contacting the object, the molecules inside the object will continuously vibrate, thereby conducting heat.Vacuum heat treatment process optimization of reducer gear shaft Convection is the transfer of heat through the flow of a fluid medium, such as air or liquid. The heat generated by the heating element inside the aging furnace causes the surrounding air or liquid to expand and form a convection flow, which transfers heat to the surface of the object. This convection heat transfer method can speed up the heating of objects and improve heating efficiency.Vacuum Heat Treatment for Gear Manufacturing Radiation refers to the spread of thermal energy in the form of electromagnetic waves, and heat is transferred through radiation. The high temperature generated by the heating element in the aging furnace emits thermal radiation, which can pass through air or vacuum and transfer heat directly to the surface of the object without a medium. Radiation heat transfer has the characteristics of no need for medium transfer and fast heat transfer speed. For objects that are not easy to transfer heat by conduction or convection, radiation heat transfer plays an important role.Application example of vacuum heat treatment technology in mold Posted at 11:24 PM

Operation of the chamber furnace Regularly check whether the hot wires of each part are loose, whether the contacts of the AC contactor are in good condition, and repair them in time if any fault occurs. If the user can abide by the above operating procedures during normal use, if the product does not work normally due to product quality, it will be repaired and replaced for free within one year, until the product is replaced. However, the user is not allowed to disassemble and assemble it without the quality principle verified by the manufacturer, otherwise the user shall be responsible for various maintenance and repair costs.Vacuum carburizing process of transmission gear For silicon carbide rod furnaces, if the silicon carbide rods are found to be damaged, replace them with new silicon carbide rods with the same specification and similar resistance value. When replacing, first remove the protective covers at both ends and the chucks of the silicon carbide rods, and then take out the damaged silicon carbide rods. Since the silicon carbide rods are easy to break, care must be taken during installation. Vacuum Heat Treatment of Carbon Boron Steel Fasteners Tighten so that it makes good contact with the silicon carbide rod. If the chuck is severely oxidized, it should be replaced with a new one. The gaps at the installation holes at both ends of the silicon carbide rods should be blocked with asbestos ropes. The muffle furnace temperature shall not exceed the working temperature of 1350°C. Silicon carbide rods are allowed to work continuously for 4 hours at temperature.Correct use and maintenance of vacuum brazing furnace After the muffle furnace has been used for a long time, if the heating power adjustment knob is adjusted clockwise to the maximum position, the heating current still cannot be increased. If it is far from the rated value and cannot reach the required heating power, it means that the silicon carbide rod is aging. At this time, the silicon carbide rods in series can be changed to parallel, and they can still be used continuously. It is not necessary to disassemble the silicon carbide rod when changing the connection method, only to change the connection method, and after changing the connection method, pay attention to slowly adjusting the heating power adjustment knob when using, and the heating current value must not exceed the rated value.Influence of Vacuum Brazing Process on Microstructure of Tungsten and Steel Posted at 11:00 PM

Vacuum Furnace
Vacuum furnaces are mainly used for ceramic firing, vacuum smelting, degassing of electric vacuum parts, annealing, brazing of metal parts, and ceramic-metal sealing. The oxidation and decarburization of the surface of the workpiece during the heating process are completely eliminated, and a clean surface without deterioration layer can be obtained. This has a great bearing on the improvement of cutting performance for those tools that only grind one side during sharpening (such as twist drills that directly expose the decarburized layer on the groove surface to the cutting edge).

Solid wood flooring on the issue of wear and tear. The more common solid wood floorings have many specifications. The general standard size is: 910mm��120mm��18mm, and the thickness of 18mm is the mainstream wooden floor specifications. However, the specifications of long-width wood flooring are different depending on the material of the solid wood floor. The specifications and dimensions of wood flooring that can be processed can also be different. For example, wood flooring species such as oak, oak, disc bean, etc., because of its large tree diameter, the processing of the floor slab size is also very large, the current market size of more than 1000MM will also use these materials, and like the rosewood Rare and precious tree species such as rosewood, rosewood, etc. The original tree has a long growth cycle and a small diameter. Therefore, there are only a small number of standard wood floor sizes sold on the market, and most floor specifications are small plates with a width of less than 60 mm.
