The focus pusher is made of Q345-B material, with water cooling wall; it is made of 16Mo3 material, without water cooling wall. Since the coke pusher is the core component of the coke pusher equipment and even the entire coke oven machinery, if the design structure of the coke pusher is unreasonable or the material is improperly selected, the entire coke discharge process will be affected. Therefore, it is very important to choose the structure and material of the focus pusher reasonably. The design structure, material and advantages and disadvantages of the two focus pusher rods are introduced below.HIGH SPEED CIRCULAR SAWING MACHINE HY-120NC The design concept of Yankuang 7.63m coke oven machinery is environmental protection, structural optimization and energy saving. Therefore, the coke pusher they designed is a cooling wall structure, that is, the coke pusher is cooled by circulating water, so that the coke pusher will not be thermally deformed and cracked due to excessive temperature in the carbonization chamber. The body material of the focus pusher is Q345-B, and the structure is a box beam type with water cooling walls on both sides.HIGH SPEED CIRCULAR SAWING MACHINE HY-150NC Because there is a cooling water system in the coke pushing system to meet the supply of circulating water in the cooling wall of the coke pushing rod, 2 sets of water pumps are needed to provide power, and cooling water heat exchangers, support chains, special heat-resistant rubber hoses, and control valve groups are also required Wait. Due to the extremely complex external structure of the water system and the high performance requirements of each part, the cost of the entire equipment is greatly increased, and it brings a lot of inconvenience to daily maintenance.Vacuum heat treatment control of machining deformation of engine cast titanium casing The main advantage of this structure is that the material of the main body can be ordinary carbon steel Q345-B, which is easy to purchase and low in cost; in addition, the structure of the water-cooled wall can relieve the pressure of the coke pusher due to sudden cooling under different external temperatures. Thermal deformation and cracks due to sudden heating.Vacuum heat treatment of slender hollow parts
