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.Vacuum heat treatment of 3Cr2W8V steel-aluminum die-casting mold 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.Research on Vacuum Heat Treatment Technology of Cr12 Steel 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.C6180A UNIVERSAL LATHE Generally, when the coking time changes, all the indicators must be changed accordingly.

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

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.X6333 X6333A TURRET MILLING MACHINE 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.X5032 X5040 VERTICAL METAL KNEE TYPE UNIVERSAL MILLING MACHINE 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.Degreasing Process in Ceramic Injection Molding 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.

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%.Prevention method for grinding cracks of vacuum carburizing and quenching gears 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. Pit Type Furnace Nitriding Process And Operating Procedures Various types of calciners rely on "cyclone effect", "spray effect", "suspension effect" and "fluid effect", so that the dilute in-phase air flow can be highly dispersed in the furnace, increase the contact area between the material and the hot air flow, and prolong the material flow. The residence time in the decomposition furnace can improve the combustion efficiency, improve the heat exchange rate and improve the decomposition rate of the raw meal entering the kiln. There are more than two types of airflow movement in the decomposing furnaces used in daily life. However, from a macro perspective, the technical principles of various calciners are basically the same, and with the maturity of decomposition technology and the mutual penetration of technology, various precalciners have similar structural forms in process devices and calciners.Influence of Vacuum Tempering Treatment on Carburized Gears
