The government work report put forward “accelerate the implementation of innovation-driven development strategies, transform the traditional engines, and create new engines.†A new footnote was made in WISCO: Yesterday, after 23 months of innovative R&D, the industrial furnace combustion detection and control system was successfully domesticated in Wuhan Steel. The equipment's operating rate is 100%, and the energy efficiency is improved by half. While realizing the value of promotion, it has successfully built a new engine for localization of industrial equipment.
Radiant tube regenerative industrial furnaces are widely used in the metallurgical industry for silicon steel and cold-rolled heat treatment production lines. There are 350 sets of WISCO's online operations, all imported from abroad. In the production process, burners and regenerators on industrial furnaces are consumable parts. Only a handful of domestic manufacturers can provide spare parts, but the provided burners and regenerators have short life spans and low operating rates. Every three months will require Once replaced, it will not only affect the product quality of the unit, but also impede the improvement of production efficiency, and the occurrence of burning noises in the production often causes safety hazards.
“No need to use, there are many hidden dangers.†For the problems that have plagued field personnel for many years, the Stock Equipment Management Department has taken this as a major scientific and technological project of the company in 2013, which was handed over to Yang Xianfa Innovation Studio of the Equipment Department for research.
Yang Xianfa led the studio team to start researching the combustion flame detection technology and overcome the next one. After more than six months of time and through hundreds of targeted improvements, the company successfully developed an ion current detection device, studied the ignition control technology, and solved the problem of burning. The problem of cracking the mouth; improving the ignition method of the main burner to ensure the ignition success rate; developing a new type of burner to improve the mixing effect of gas and air.
In the end, the localization research and improvement project of the industrial furnace combustion detection and control system, which included 1 software copyright, 4 patents, and 5 technical know-how, was successfully completed at WISCO, and in May 2013 it began to be connected to the silicon steel CA9 line and cold rolling. Perform test run on 7 sets of equipment on the exit line.
As of early April 2015, after 23 months of verification, the first time in the country successfully applied the ion flame detection device to the combustion system. The success rate of the first firing of the burner increased from 40% to 100%, and the flame detection rate increased from 50%. To 100%, while ensuring the stable operation of the unit, and improving production and quality, the energy saving is 7439JG and the cost is reduced by more than RMB 1 million.
Radiant tube regenerative industrial furnaces are mainly used by the production and technical personnel of the unit silicon steel division. They are very satisfied with the research results. They commented that the reformed industrial furnace burners and regenerators not only changed the convention of changing every three months, but also The continuous production of the unit has been significantly enhanced. After the upgrade of 350 sets of Wuhan Iron & Steel Online equipments in the later stage, it will produce radiation effects in improving quality, increasing efficiency, and saving energy.
Air Valve double chamber:
1. Application: water transition pipes
2. Function:
a. when the pipe is being filled with water, the air valve automatically let air out of the empty pipes. The air must be released rapidly to make sure that the pressure does not increase in that area as flow is restricted by the air in the pipe.
b. when the pipe is being empty, the air valve must let air into the pipes rapidly to prevent the pressure from dropping and forming a vacuum in the pipe.
c. automatically remove the air bubbles forms at the high points of the pipes or move through the pipes to prevent them reduce the water flow through the valves.
3. Surface coating:
Internally and externally coated with fusion bonding epoxy coating of minimum thickness of 250um. As required, Certification corresponding to drinking water like KTW, WRAS could be available.
4 Quality traceability
All the valves are with serial no. which could ensure the traceability of the production and quality control.
