According to the data, the furnace averaged 1003 degrees per day in July, used 1371 degrees per day in August, and used 1020 degrees per day in September. After the improvement, the average daily electricity consumption of the furnace in October and November dropped to 205.4. degree.
It is reported that the three bottles and cans will be copied and promoted to the 7-4 and 6-3 machines respectively.
The three production lines of Guangdong Huaxing cans with an annual production capacity of 150,000 tons are actively responding to the requirements of the company's control of costs. The company independently carries out independent innovations in the main cost-consuming aspects of water, electricity and gas, rationally utilizes resources, and reduces production costs. manufacturing cost. The daily-use glass industry as a "high-energy-consumption" manufacturing industry, with the rising cost of raw materials, energy saving and consumption reduction is a top priority for enterprises. The third bottle will reduce energy consumption as the main goal of cost control.
Among them, the 7-5 machine annealing furnace is a SCR electric heating annealing kiln, which is used together with the 7-5 row-type bottle machine. The 7-5 bottle-type bottle-making machine is a 10-group double-drop machine of OI type imported from the United States, mainly producing small-mouth bottles of 300 grams or more. The 7-5 machine annealing furnace uses a large amount of electricity, which becomes a difficult problem for the department to control the cost. According to statistics, from May to August 2009, the average monthly power consumption reached 26,393.6 degrees, exceeding the company's control standards.
For this purpose, the three bottles and bottles were organized for research.
In July, the security office improved the pusher of the pusher, changing from 30 teeth to 32 teeth, increasing the mesh belt fullness, reducing the heat dissipation space, increasing the temperature in the kiln, and reducing the power consumption; at the same time, slowing down the mesh belt. Speed, increase the glass bottle annealing time; In cooperation with the power department, an additional frequency converter in the annealing zone 1, adjust the fan speed in zone 1. Statistics later showed that the improvement was not satisfactory.
In August, the joint power department of the three bottles and cans once again tackled the problem and adjusted the direction of operation of the annealing furnace. The clockwise direction was changed to counter-clockwise rotation to change the air pressure; the frequency, speed and frequency of the annealing furnace were increased in the first, second and third areas. In vivo thermal uniformity, but the improvement is still not achieve the desired goal.
All the employees of the three bottles and bottles were immersed in meditation. Where is the power consumption? In the face of difficulties, everyone did not shrink back, brainstormed, and continued to carry out improvement work.
In late September, the original three bottles of the first three bottles of the process director transferred to serve as the third generation of bottle managers, for the 7-5 machine power consumption problem, convene the relevant staff of the department to discuss.
During the discussion, the remaining three orders indicated that if the problem of power consumption is not solved as soon as possible, the electricity consumption in winter will be even greater, and the work of reducing consumption will be imperative. All the heat preservation work must be carried out. At the end of September, under the leadership of the Director of the Office of Protection Xiao Yongquan, the first stove head insulation was improved, and an insulated iron plate was installed on the stove head to block the cool air from the machine table. At the same time, the comprehensive class uses composite silicon thermal insulation coatings to cover the furnace insulation. At the beginning of October, the comprehensive Ban Gan Hu installed thermal insulation cover on the top of the bottle car and the turning machine, and added 5CM thick composite silicon insulation coating on the surface of the cover plate. This series of improvements can maintain the temperature of the hot bottle into the furnace, and the heat emitted from the hot bottle can increase the temperature in the furnace.
After the improvement was completed, the integrated monitor Gan Jinhu followed up on the amount of electricity used for annealing each day and found that the power consumption was greatly reduced. At the same time, the product was stress-tested and the product reached three levels of stress and met the quality control standards.
