(1) Reduce the rate of burnout of the purlins. Under normal circumstances, the consumption of purlins is 0.03 to 0.1 kg per ton of sintered ore. The consumption of the bars has a certain impact on the cost of the sinter.
(2) Maintain a fixed effective ventilation area. When the primer is not laid, the sinter may stick to the crepe to reduce the suction area, and the sintered material of the bonded portion is not burnt well, thereby reducing the yield of the sintering machine and increasing the return rate. In order to avoid sticky sticks, some factories adopt a method of not burning, but this will affect the quality of the sintered ore.
(3) Extend the life of the exhaust fan rotor and increase the operating rate of the sintering machine. During the exhaust sintering process, fine ore particles are drawn into the bellows with the exhaust gas, pass through the large flue, enter the exhaust fan, and accelerate the wear of the rotor blades. This situation is even more serious when using all concentrate powders to be sintered, and some plants are worn out in less than a few weeks. After the bottoming material is laid, part of the fine ore powder is blocked, and the amount of ore powder carried by the exhaust gas is greatly reduced, thereby prolonging the life of the exhaust fan and correspondingly increasing the operating rate of the sintering machine.
(4) Improve the sintering operating conditions and facilitate automatic sintering control. The production practice proves that when the bottoming material is not used, the sintering machine trolley returns more material under the lane, and a special cleaning device is required. After the bottoming material is used, the trolley material of the trolley is basically eliminated, and no special cleaning device is needed, which is convenient for automatic control of the sintering machine.
The cooled sintered ore is sieved twice to obtain a primer. Some foreign factories use 8 to 15 mm or 10 to 15 mm of finished ore as the bottoming material, >15 mm for the blast furnace, and <8 to 10 mm for the returning ore. This method requires 1) to establish screening equipment , 2) a special system to send the primer to the high point of the sintering plant, and 3) to add a bottom storage tank. Practice has proved that as long as the design is reasonable, this method will not affect the operating rate, and can reduce the loss of the purlin by 30-50%, greatly extending the life of the exhaust fan rotor. In addition, the quality of sinter production has improved, which is an important part of China's sintering technology transformation.
The role of the primer and the method of obtaining the primer
There is still a part of the sintering machine in China that does not have a bottoming system, and the sintering material is directly laid on the furnace bar. When the ribbon is reached under the sintering belt, the high temperature exhaust gas of the sintering belt may burn the crucible or adhere the molten liquid phase to the grate. Therefore, a layer of fuel-free charge should be placed between the sintered material and the bar, called the primer. The main role of the primer is four points:
The drilling tapping center is mainly used for processing light and small metals, especially suitable for fields such as 3C electronic structural components, mobile phone parts, automotive parts, etc. Drilling and milling center, also known as drilling and milling center or drilling center, is an efficient CNC machine tool mainly used for processing light and small metal parts. It integrates multiple machining functions such as drilling, milling, and tapping, making it particularly suitable for scenarios that require high-precision and high-efficiency machining. The main uses of drilling centers include:
Processing of 3C electronic structural components: Drilling and tapping centers play an important role in the manufacturing of consumer electronics products, especially in the processing of components for devices such as mobile phones and tablets. Due to its high efficiency and suitability for small-sized workpieces, drilling and tapping centers are widely used in the 3C industry.
Automotive parts manufacturing: In the automotive manufacturing industry, drilling and tapping centers are used to produce engine parts, gears, housings, and other components. By quickly completing a large number of drilling and tapping operations, production efficiency is improved.
Mold manufacturing: The drilling and tapping center can quickly process high-precision molds to meet the needs of product molding and is suitable for the processing of various mechanical components.
Communication equipment manufacturing: Precision components of communication equipment also require high-precision machining, and drilling and tapping centers can meet these requirements to ensure product quality and reliability.
Compared to ordinary drilling machines, drilling centers have higher machining accuracy, wider machining range, simpler operation, and higher production efficiency. It adopts CNC technology for precise control, can handle workpieces of various specifications and materials, and is easy to operate, suitable for large-scale production.
In summary, drilling centers play an important role in multiple fields, especially in the manufacturing of lightweight and small metal components that require high-precision and high-efficiency machining.
