Aluminum aging found that the hardness of this alloy was not high after quenching, but after a period of time at room temperature, the hardness increased significantly. This phenomenon was later called precipitation hardening. This discovery has generated great interest in the engineering community.What are the characteristics and advantages of the MIM process? Later, people successively discovered some aluminum alloys, copper alloys and iron-based alloys that can be strengthened by aging treatment, and created a new strengthening method that is essentially different from general steel quenching strengthening - aging strengthening. Solidification before aging treatment During the solution treatment, the heating temperature must be strictly controlled so that the solute atoms can be dissolved into the solid solution to the maximum extent without causing the alloy to melt.On-line quenching and tempering of high strength steel plate The allowable deviation of heating temperature for solution treatment of many aluminum alloys is only about 5°C. For artificial aging treatment, the heating temperature and holding time must be strictly controlled in order to obtain an ideal strengthening effect.AUTOMATIC HORIZONTAL BAND SAW FOR PROFILE GH4260/80 Sometimes segmented aging is used in production, that is, first keep warm for a period of time at room temperature or a temperature slightly higher than room temperature, and then keep warm for a period of time at a higher temperature.

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.Aluminum alloy vacuum brazing of heat exchangers 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.Vacuum Brazing of EGR Stainless Steel Cooler 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.SX4-DIGI BENCH MILL DRILL 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.SX4 BENCH MILL DRILL

Three details that are easy to ignore when using a box type resistance furnace 1. When using a box-type resistance furnace to heat the workpiece, no setter plate is added: the box-type resistance furnace manufacturer has equipped a corresponding size setter plate for each box-type resistance furnace. All heating workpieces, including the container for the workpiece, should be placed Heat on the setter plate. Try to avoid placing the ceramic fiberboard directly at the bottom of the furnace, which will cause uneven stress on the fiberboard or high local temperature, which will damage the bottom of the box-type resistance furnace.HORIZONTAL ROTARY ANGEL METAL BAND SAW MACHINE G4240X70Z 2. Want the box-type resistance furnace to cool down quickly, and open the furnace door when the temperature is high: Because the box-type resistance furnace has a very good insulation effect, the energy consumption during insulation is very low, and the temperature drops very slowly after the power supply is stopped.HORIZONTAL ROTARY ANGEL METAL BAND SAW MACHINE CH-300S Some customers hope that the next experiment can be carried out immediately after one experiment is completed, so they open the furnace door at high temperature to obtain a high cooling rate, but this will cause great damage to the furnace chamber of the box-type resistance furnace, and it is easy to cause a cold and a hot. The furnace is cracked, and the heating element of the box-type resistance furnace cannot withstand such a thermal shock.Vacuum brazing of elliptical corrugated horn We generally recommend that the box-type resistance furnace is at least cooled to 600 ℃ before carefully opening the furnace door a little. If high temperature pick and place parts are indeed required, consideration should be given to whether a silicon carbide furnace can be used. 3. Do not bake the oven when it is used after a long shutdown: This is also a detail that is easy to ignore. Basically, all customers can do the oven when the box-type resistance furnace muffle furnace is used for the first time, but many customers will Forget the oven when it is used again after a shutdown of more than a week.

The function and function of the calciner There are three main functions of the decomposition furnace: one is to make the fuel have sufficient burning time in the furnace, and the theoretical burning degree should reach 100%, so that the heat of the fuel can be released to the maximum. The second is to maximize the dispersity of the material through intense swirling and spouting, and to promote sufficient heat exchange with the hot gas in the dispersed and suspended state. The third is to promote the rapid decomposition of calcium carbonate, and the decomposition rate should reach more than 90%.Vacuum Heat Treatment Process of Machine Tool Spindle To achieve the above purpose, the dilute solid-phase gas flow in the decomposition furnace should have a relatively stable flow field, concentration field, temperature field and pressure field. The calciner has been developed and improved many times from its birth to today. There are various types of derivation and derivation, and there are 37 types in five categories. According to the movement form of air flow, it can be roughly divided into swirl-spray type, pre-combustion chamber-spout type, fluidized bed-spout type and suspension pipeline type.
