Jinyuan Chemical Calcium Carbide Production in Beiyuan, Shaanxi Province

Since this year, Jinyuan Chemical Industry Co., Ltd. of Shaanxi Beiyuan Chemical Industry Group has positively deployed and advanced the implementation ahead of time, with "safe, stable, long, full and excellent" operation as the main line, and with the standardized management of calcium carbideas the focus. Starting from the aspects of production management, process adjustment, equipment inspection and management, standardization of inspection and maintenance operations, and strong quality control, we are determined to walk out of the production dilemma and successfully realize the first month's "open door" production. As of January 31, the output of calcium carbide was 25229.18 tons and the monthly plan was 100.92%.

Firstly, the key process indexes should be strictly controlled and the operation should be unified. We should adhere to the unified operation of each team to achieve uniform material ratio, uniform current control range and uniform number of tapping times. If adjustments need to be reported layer by layer to the director for consent, the operation can be adjusted. We should standardize tapping operation, rationally arrange tapping times, strictly control tapping time, and keep the furnace temperature within the appropriate smelting temperature range. The furnace runs smoothly and satisfactorily.

The second is to strengthen the inspection of the main equipment defects and make up for deficiencies. Recently, cleaning and dust removal equipment often fails to stop, which has become a key factor restricting production. The main reason is that the cleaning and dedusting equipment has insufficient power to collect and filter the furnace gas in the furnace, resulting in unstable furnace pressure, material collapse, and furnace temperature often running in the red zone, which eventually leads to frequent power outages and maintenance of the electric furnace. After discussion and demonstration by the factory director and technicians, we tried to increase the pressure of back-blown nitrogen and arrange the planned parking to deal with the material surface regularly. At the same time, it is necessary to discharge the ash from the ash storage tank of the purification system by a special person. The problem of unstable furnace pressure and insufficient purification power of the furnace gas of the purification and dedusting equipment can be solved by discharging the ash regularly and quantitatively. After the transformation, the operation indexes of electric furnace tend to be stable, the data indexes tend to be stable, and the operation rate is constantly rising.

Third, actively carry out the selection of merits and benchmarking, learn from each other's strengths and make up for each other's weaknesses. Through the exchange and study with similar enterprises, the adjustment and improvement of production process parameters have been made. The company requires each section to adjust the raw material ratio and operation method in time according to the furnace condition of the calcium carbide furnace. The daily production operation control, process index control and equipment operation control are taken as the focus of production work to ensure the production quality. Reaching the target. 4 is to decompose production tasks step by step, everyone is responsible. In order to ensure the fulfillment of production objectives, the company requires that the output be decomposed into sections and teams, and that the actual daily output, unit consumption indicators and output differences be recorded in detail, and the causes be carefully analyzed and found, so that personnel at all levels have a production target account in mind, so as to promote the formation of index competitions between groups and sections, and then compare. To achieve good results.
