The traditional carbon-based hot feed of converter generally contains more than 10% asphalt/resin, which is carried out by the construction personnel during use. The material is manually put into the furnace to be repaired. Under the action of high temperature, organic matter such as asphalt is softened and liquefied, giving the material good bonding property and certain flow performance, so that the feed can be bonded and paved in the position that needs to be repaired. And form a solid carbon bond, to achieve the purpose of repairing the furnace lining. Furnace lining repair material manufacturers for you to introduce
This construction method is mainly manual throwing, with high labor intensity, low working efficiency, bad working environment, short throwing distance, inaccurate throwing position and serious waste of materials.
In order to solve the above problems, Lianhe Rongda adopts the replacement machine to replace the manual operation in the converter maintenance site, and has achieved good results. The technology has the following main features:
First, the machine frame is provided with an upper and lower transmission belt, and connected with the drive device in the frame, there is a gap between the two transmission belts, and the machine through the relative movement of the upper and lower transmission belt, the feed pack between the two transmission belts is catapult into the converter furnace.
Second, a walking wheel is installed at the bottom of the frame of the throwing machine, and a pushing hand is installed on the frame, and a supporting rod is connected between the pushing hand and the walking wheel to facilitate the rapid steering and movement of the equipment on the site.
Third, by setting the walking wheel, pushing hand and supporting rod, it is convenient for workers to control the throwing direction of the feeding package. Sex.
Fourth, the front and outside of the equipment is equipped with a fire shield to effectively isolate the heat source, and the side is equipped with a protective cover to prevent the material package from falling out from the side or other dangers.
Fifth, the structure and operation mode of the equipment are relatively simple, which is convenient for field personnel to operate and maintain.
Sixth, the packaging requirements of the feeding material package are equivalent to manual throwing, and the use of ordinary woven bags is packaged into a certain amount of bag form, and the weight is controlled at 3 kg (positive and negative deviation < 0.1 kg).
During the filling time, the filling material is manually placed into the receiving port of the filling machine one bag at a time, and the filling material can be shot into the furnace through the acceleration of the conveyor belt, which can easily and quickly complete the filling of the large surface, small surface, trunnion area and molten pool part of the converter.
Field industrial application practice shows that the new technology of hot state replenishment is faster, the direction of replenishment is perfect, the stability of fixed point replenishment is good, the feeding is more uniform and easy to sintering, and the parts that are difficult to repair such as the trunnion, molten pool, slag line can also be repaired well, which can effectively improve the repairing efficiency of the replenishment for the maintenance of the converter and reduce the labor intensity before the furnace. Avoid material waste.
