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.ZK5140C/I ZK5150C/I ZK5163C/I CNC VERTICAL DRILLING MACHINE 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. 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.Vacuum heat treatment of corrugated spring bayonet connector 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.Analysis of carbon content on the surface of carburized parts

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.HIGH SPEED CIRCULAR SAWING MACHINE HY-180NC 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.CS SERIES COLD CUT CIRCULAR SAWS 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 heat treatment of sheet parts 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%.Vacuum Brazing of Cemented Carbide and Martensitic Stainless Steel 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. Application of Pressureless Sintering of Silicon Carbide Ceramics 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 Reaction Sintering Process on Properties of Silicon Carbide Ceramics

The boiler is one of the important equipments in power plants and other industrial enterprises. Its function is to convert the energy stored in the fuel into heat energy through combustion, and transport it to various equipment in the form of steam or hot water. At present, most of the industrial boilers in our country are controlled manually, or are regulated by a simple instrument and a single-loop system, which wastes a lot of fuel. Vertical double-barreled shotgun receiver vacuum heat treatment As a whole, the industrial boiler has many controlled and controlled variables and many disturbance factors, and there is obviously a complex relationship between many parameters. For the complex system of industrial boiler, because the internal energy conversion principle is too complicated, it is difficult to achieve the ideal control effect by conventional control in the past. Therefore, the intelligent control method can obtain better control effect.Compound Gas Nitriding Treatment Process For Swing Arm Bogies As an important power equipment, the task of the boiler is to supply qualified steam and make the boiler evaporation meet the requirements. For this reason, the main parameters of the production process must be strictly controlled. Boiler equipment is also a complex control object. The main input variables are load, boiler feed water, fuel amount, desuperheating water, supply air and induced air, etc. The main output variables are drum water level, steam pressure, superheated steam temperature, furnace negative pressure, excess Air, flue gas oxygen content, etc.Compressor impeller vacuum heat treatment These variables are related to each other. For example, changes in steam load will inevitably cause changes in drum water level, steam pressure and superheated steam temperature. Therefore, boiler equipment is a multi-input, multi-output and interrelated control object.

Construction of modern tubular heating furnaces There are three types of linings commonly used in modern tubular heating furnaces: brick structure, refractory fiber spray structure and castable structure.How to Update your heat treatment brick structure Brick lining is made of refractory bricks, including standard refractory bricks and special-shaped refractory bricks.
