The practical operation sequence of cable annealing furnace production mainly includes the content
Oven operation: the oven is in accordance with the predetermined oven curve, its purpose is to remove the moisture in the masonry, and make the brick transformation, avoid the masonry cracking and peeling phenomenon, and affect the service life of the lining.
Open and shut down operation: according to the operation rules of industrial furnace, use the equipment reasonably, and do the preparation, open and stop the furnace correctly, otherwise it will easily cause equipment and human. Thermal regulation: In order to ensure the normal production, adjust the heating, Shanghai temperature, furnace pressure and other thermal parameters in a timely manner, in order to grasp the furnace fuel combustion or power supply.
Daily maintenance: industrial furnace in the process of use, in order to maintain its good condition or maintain its working capacity to carry out various operations, such as equipment spot inspection, regular inspection, equipment lubrication and maintenance. When the oven to comply with the rate of heating, heat preservation time and time temperature to express the chart, known as the oven curve. Oven curve is to ensure the quality of the trolley oven.
Cable in industrial furnace is a thermal equipment used in industrial production to heat materials or workpieces by using the heat of fuel combustion or electrical energy conversion. Broadly speaking, the boiler is also a kind of industrial furnace, but it is not traditionally included in the scope of industrial furnace. Industrial furnaces are divided into two types according to heating mode: one is flame furnace (or fuel furnace), which USES the burning heat of solid, liquid or gas fuel in the furnace to heat the workpiece; The second type is the electric furnace, in which electric energy is converted into heat for heating.
For aluminum alloy wire annealing furnace, high strength refractory brick can be selected partly, or a layer of high temperature plastic refractory fiber felt can be pasted on the lining surface of heavy refractory brick. Trolley furnace preheating air, gas and charge to reduce the temperature of flue gas from the furnace, that is, to reduce the heat loss of flue gas away, the effective way is to use flue gas waste heat to preheat gas, air and charge. Preheating air, gas and charge is equivalent to recovering some heat directly into the furnace, which has obvious effect on strengthening combustion and saving fuel. With the increase of air preheating temperature, the fuel saving rate also increases. Use a trolley furnace or replace an empty furnace with a through furnace with a preheated section. The use of high temperature flue gas preheating charge in the heating chamber can greatly reduce the flue gas from the furnace. For example, the flue gas of 1300℃ in the heating chamber can be reduced to 900℃ after preheating the charge through the preheating section, and the heat taken away by the flue gas can be reduced by 38%. If the thermal efficiency of the trolley furnace is maintained unchanged, the fuel consumption can be about 15%. The application effect of industrial electric furnace heat treatment technology is as follows: reduce quenching, grinding crack: in railway, rolling mill bearing production.
After the completion of the work of the aluminum alloy wire annealing furnace, the tongue plate is restored to keep the straight line unblocked. Pipe systems are made of seamless steel tubes connected by flanges. The use and operation of the pneumatic sample sending device is very simple. The sample or analysis result is put into the sample sending box, and then the sample sending box is put into the receiving and receiving cabinet by pressing the door opening button, and then the sample sending box is sent to the designated place at a speed of 10-15m /s. In order to make the electrode can rise and fall freely and prevent the electrode from breaking when the cover of industrial electric furnace is deformed by heat, the diameter of the electrode hole should be 40-50mm larger than the diameter of the electrode. Such a large gap between the electrode and the electrode hole is very unfavorable for smelting, resulting in a large number of high-temperature furnace gas escape, not only increased the heat loss, but also easy to cause the electrode temperature on the top of the furnace cover to rise, oxidation intense, electrode thin and easy to break, so it is necessary to use the electrode sealing ring. In addition, the sealing ring can also cool the furnace cover around the electrode hole, improve the life of the furnace cover, and help to maintain the atmosphere in the industrial furnace.
