How to Prevent Electric Heating Reaction Kettle Rupture during welding
Electric Heating Reaction Kettle welding process and specification, the use of high current, rapid welding, single-layer welding, straight line forward, etc., easily lead to welding stress process measures will lead to hot cracks. Therefore, when conditions permit, should try to use a small current, multi-layer welding, in order to reduce the tendency of hot cracks. Welding structure of the larger stiffness of the workpiece, often used preheating method.
Electric Heating Reaction Kettle Preheating on the one hand can reduce the cooling rate, slow down the tensile stress generated during the cooling process, on the other hand can also improve the crystallization conditions, reduce the chemical and physical heterogeneity. The preheating temperature depends on the chemical composition and the structural stiffness of the steel. The higher the carbon content of steel, the more alloying elements, the greater the work stiffness, the higher the preheating temperature is required.
Electric Heating Reaction Kettle Due to the high operating pressure, the pressure inside the tank is generated by a chemical reaction or is caused by an increase in temperature. The pressure fluctuates greatly and is sometimes unstable. The sudden increase in pressure may exceed several times the normal pressure. , Most of the Electric Heating Reaction Kettle belonging to the pressure vessel, to strictly prevent the occurrence of cracks.
Electric Heating Reaction Kettle is a generalized understanding of the physical or chemical reaction of the container, through the container structure design and parameter configuration, to achieve the required process of heating, evaporation, cooling and low-speed mixing function. Then Electric Heating Reaction Kettle specifically why it is used, the following Electric Heating Reaction Kettle manufacturers for everyone to introduce:
Electric Heating Reaction Kettle is a comprehensive reaction vessel that is designed according to the reaction conditions for the structure and function of the Electric Heating Reaction Kettle.
From the beginning of the feed - reaction - the discharge can be a higher degree of automation to complete the pre-set reaction steps, the reaction process temperature, pressure, mechanical control (stirring, blowing, etc.), reactants / products Concentration and other important parameters for strict control.
Electric Heating Reaction Kettle is widely used in petroleum, chemical, rubber, pesticide, dyes, pharmaceuticals, foodstuffs, pressure vessels for the process of vulcanization, nitrification, hydrogenation, alkylation, polymerization, condensation and other processes such as reactors, Decomposition furnace, polymerization reactor, etc .; materials are generally carbon and manganese steel, stainless steel, zirconium, nickel (Hastelloy, Monel, Inconel) alloys and other composite materials.
Electric Heating Reaction Kettle Manufacturer Tips: Electric Heating Reaction Kettle is a reaction equipment that must be noted during operation, otherwise it will cause damage due to many reasons, resulting in production being forced to stop.
Electric Heating Reaction Kettle biggest role is to achieve the process of raw materials such as poly, to meet the raw material production process, to achieve the desired production. However, it should be noted that the operation is to be standardized, if the use of Electric Heating Reaction Kettle when the wrong operation steps will cause damage, affecting production. Let's take a brief look at Electric Heating Reaction Kettle.
First, in strict accordance with the system operation
Strictly regulate the system operation, which is the most basic requirements of the operation. Before operating Electric Heating Reaction Kettle, you should understand the standard operating system for the equipment. Although the equipment specification to provide regulatory information is not very detailed, but some must comply with the system must be done in order to ensure the safety of equipment operation.
Second, before the operation check
Before operating the Electric Heating Reaction Kettle, check to see if there is any abnormality in the equipment. If the equipment in normal operation, must not cover and touch the board to open, so as to avoid electric shock phenomenon. In the operation of the time is strictly prohibited with the pressure operation, so that not only damage the equipment, while a security risk. In the process of nitrogen pressure test, we should pay attention to its changes, so as not to pressure is too high.
Third, pay attention to observation
When operating the Electric Heating Reaction Kettle, observe the observation and observe each operation step. Especially Electric Heating Reaction Kettle heated to a certain stability, do not and kettle body contact, so as not to burn. After the completion of the experiment, the first to be cooling treatment, waiting for the temperature cooling, so as not to cause damage to the equipment caused by high temperature, in addition to timely unplug the power.
