Regular Maintenance And Care Of Steel Rolling Equipment

Enterprises should develop a rolling mill regular maintenance and maintenance system, but also to support the construction of routine maintenance and maintenance system, the specific content of the following aspects.

1. To regulate the daily operation of equipment users, assessment of their operating behavior, the behavior that may cause damage to the steel rolling mill machinery and equipment must be ordered to prohibit, and the use of personnel in the formal onboarding before the operation assessment, after passing to officially start. At the same time, in the process of daily operation should be set up to inspect and supervise the behavior of staff, and establish a clear system of rewards and punishments, so that staff can pay attention to the standardized use of equipment, thereby reducing the chances of equipment failure.

(2) Steel rolling equipment failure or abnormalities to timely maintenance, equipment failure if not timely maintenance, will make the equipment with damage for a long time to run, may expand the scope of failure, reduce productivity, and will have a serious impact on the overall performance of the equipment. Therefore, steel production enterprises should establish a perfect point inspection system, for the operation of equipment prone to failure points and the main power point of the operation of the equipment for regular, regular maintenance and maintenance, and like the transmission mechanism, spindle and other parts of the repair and maintenance must be strictly implemented in accordance with the factory instructions, so as to truly solve the equipment failure, extend the service life of the equipment, and improve the utilization of enterprise resources .

(3) To establish a comprehensive equipment maintenance system specifications. Perfect equipment maintenance system specifications is an indispensable complementary facility for steel enterprises to effectively manage rolling mill machinery and equipment, to effectively avoid the decline in production efficiency and economic losses caused by untimely maintenance of equipment. Therefore, steel production enterprises should establish a special machinery and equipment maintenance and conservation department for unified, standardized management, and the system of maintenance and conservation norms to the actual work, so that each maintenance personnel can be clear about their own responsibilities, so as to prevent the emergence of failure when the use of personnel and maintenance personnel to shirk responsibility for each other’s problems. In addition, the system of fixed person and machine should not be changed at will, but also strictly forbid staff to change positions at will.

2. The maintenance and maintenance of the shaft tile

Shaft tile in the operation of rolling steel equipment often appear problems, once the problem will make the subsequent operation can not maintain a balanced state, and if the bearing part of the cleaning is not complete, then also in the pouring process because of the pasteurized alloy wear reduction layer and bearing shell between the poor connection, thus affecting the quality of steel, but also cause the equipment as a whole to react badly. In addition, the role of the journal will have a certain impact on the performance of the steel, because it will act on the shaft tile, so it leads to insufficient and uniform contact between the shaft tile and into the shaft, which will affect the uniformity of the heat of the raw material, once the uneven heat situation, it will have a negative impact on the quality of steel.

 

Usually, for the repair and maintenance of the shaft tile, we should pay attention to two aspects: on the one hand, when pouring, we should try to avoid the bad connection between the bus alloy and the bearing shell, and we should clean the bearing lining in time to keep it clean, and it is better to use alkaline water first during the cleaning process to guarantee the comprehensiveness of the cleaning, and then use Zn saturated solution for the second cleaning after baking dry. On the other hand, to choose the appropriate scraping method, control the angle of the contact point of the shaft tile in the bearing state, preferably at 80 °, and to pay attention to the direction of scraping, as far as possible from the research point to the central position; most importantly, when scraping the shaft tile, the direction of the upper and lower scrapers should be crossed state, so as to ensure the smoothness and uniformity of scraping.
