Latest ArticlesIn order to make rotary shaft in a benign operation, delay its degradation speed and prolong its usage period, in the paper, through research on the online operation trend of large pivotal bearing in heavy plate steel ladle, damaged large pivotal bearing off the assembly line is disintegrated for research and study, and the main factors affecting the damage of large pivotal bearing are analyzed. Combined with a variety of uncertain parameters in actual production of large pivotal bearings, measures for comprehensive maintenance, installation and use are taken to delay equipment degradation speed, prolong its service life, effectively improve the casting machine production continuity of heavy plate and improve the operation rate of equipment.
Three kinds of reasons for mill scale accumulation are found by analyzing the phenomenon that mil scale is often occurred in vibrating screen of straightening machine. According to years of work experience, the corresponding measures have been taken, that is, two link stopper are welded on the outer side of lower roll box, so that the vibrating screen can be quickly cleaned online. In addition, the original design vibrating screen is horizontal. In order to make the mill scale slip out of the chute rapidly, the exit of vibrating screen is lowered by 20 mm. It is not only to prolong the mill scale cleaning cycle, but also reduce the downtime and improve the equipment operation rate. And after the transformation, effect is obvious.
In 2016, the conference for the work of national state-owned enterprises party building, General Secretary Xi Jinping proposed to strengthen and improve the party's leadership of state-owned enterprises, strengthen and improve the party building of state-owned enterprises, and making state-owned enterprises become the party and the country's most reliable power. The paper focuses on discussion for ways and means to strengthen the party building work of state-owned enterprises in the face of many problems in party building work of state-owned enterprises, and make the party construction work as a powerful push to promote the deepening reform of state-owned enterprises and improve the management level.
The Rail and Beam Plant of Baotou Steel continually refines the construction of safety management system, follows the principle of "three responsibility and three must", which combines the actual situation of the enterprise and establishes the comprehensive security system of the enterprise. Regarding the safe production responsibility implementation as the breakthrough point to strengthen the safety management and innovate the safety management method, refining the management step by step, perfecting the supervision and responsibility list content, and making a detailed list of on-site dangerous source completely. Supervise and evaluate the daily class supervision and assessment to improve on-site safety management efficiency, continuously eliminate the unsafe factors and unsafe behavior of people, so that we can promote active safety prevention capacity of our staff and form the safety management into a new mode of whole staff self-management, whole staff supervision, dare to manage and good at management.
The main causes are determined through analyzing all factors influencing the rate of abandoned well as well as the technologies and management measures for controlling the rate of abandoned well are formulated and implemented seriously to reduce the perforation costs.
The paper introduces the production status of railway steel in key domestic enterprises and the future developing direction of railway steel demand. In combination with the steel variety and the production process status of railway-steel that have been developed by Baotou Steel, it is proposed that Baotou Steel should strengthen the investigation of railway steel market, optimize the product mix of railway steel and further strengthen the countermeasures such as developing and applying new technology and speeding up the relevant product certification, so as to create good economic and social benefits for the enterprise while meeting the railway development demand of the thirteenth Five-Year Plan.
In the article, the principles, importance and requirements are elaborated starting with the stope blasting and production management aiming at the key jobs in site productions; the specific technical measures and delicacy management methods are proposed to effectively reduce waste and production costs as well as improve production efficiencies so that the whole outlook of stope is optimized and the effects are good.
