At present, aluminum alloy has the largest number of die castings. It has light weight, high specific strength, high mechanical properties and corrosion resistance, etc. However, compared with zinc alloy, its casting performance is relatively poor, and it has a tendency to stick to the mold. , it is more likely to produce defects such as oxidation, gas absorption, segregation, slag inclusions, and large crystal grains during smelting. Iron is a harmful element in aluminum alloys, but when the iron content in aluminum alloys is lower than 0.6%, it will be damaged during the production process. Die sticking is easy to occur in the medium, and when it is higher than 1%, the mechanical properties of the alloy will be reduced. The reasons for the "iron increase" of aluminum alloys mainly come from three aspects:VERTICAL LONGITUDINAL CUTTING PULLEY TYPE METAL BAND SAW MACHINE G53 SERIES 1) During the smelting process, there are many opportunities for contact between iron and alloys, such as crucibles, iron spoons, ladles, smelting tools, etc., and their surfaces should be coated with paint.330 FULLY AUTOMATIC PLC CONTROL HORIZONTAL CUTTING BANDSAWS 2) The dissolution rate of iron in molten aluminum alloy increases with the increase of temperature. When the melting temperature of aluminum alloy is higher than 750°C, it is called "overburning of aluminum alloy". At this time, the dissolution rate of iron increases rapidly.Vacuum brazing technology of laminated aluminum evaporator 3) In addition to the temperature factor, the iron increase in aluminum alloy is also related to time, that is, the longer the holding time, the more iron is added, and the air intake is also increased.

Coke oven temperature regime In order to make coke oven production stable, high-yield, high-quality, low-consumption, and long-lived, it is required that the coke cakes in each carbonization chamber mature evenly along the length and height within the specified coking time. In order to ensure the uniform maturation of coke, it is necessary to formulate and strictly implement the coke oven heating system.Low temperature vacuum hot pressing sintering of aluminum nitride ceramics Coke oven heating is a complex process affected by many factors. Changes in coke oven operation, coal loading, coal moisture, gas temperature and composition will affect the uniform maturity of coke cake and the stability of production. For this reason, the furnace temperature should be adjusted in time according to the respective changes. This requires that according to the actual data obtained by each coke oven during the adjustment period, according to different turnaround times, a corresponding heating system should be formulated and strictly implemented.What you need to know about thermocouple of vacuum furnace Some furnace-wide indicators in coke oven heating adjustment, such as coking time, standard (fire path) temperature, gas flow at the coke side, branch pipe pressure, standard regenerator top suction, flue suction, orifice plate diameter, exchange opening and closing The size of the air inlet of the device, etc., these indicators are called the basic heating system of the coke oven.X6330 X6330A TURRET MILLING MACHINE Generally, when the coking time changes, all the indicators must be changed accordingly.

Application of aluminum alloy aging furnace 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.Carbide and Steel Vacuum Brazing 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.Large diameter ring gear vacuum carburizing and quenching The allowable deviation of heating temperature for solution treatment of many aluminum alloys is only about 5°C.

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.Common Failure and Maintenance of Vacuum Quenching Furnace 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.Requirements for deep carburizing on heat treatment equipment 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.HD2525-1 CNC SINGLE- SPINDLE GANTRY MOVABLE HIGH-SPEED 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.HD3016S HIGH SPEED CNC DRILLING MACHINE
