Release time:
2023-03-04
News from our newspaper # February 8 , with the completion of the welding of the last section of pipeline, the replacement of the kiln tail chimney of Yunnan Jianfeng Cement Company was successfully completed.
When Yunnan Peak inspected the steel plate of kiln tail chimney in November of 2022 , it was found that the thickness was reduced by 2-3 mm compared with that of 2021 , and it was necessary to replace it. In addition, according to the continuous 5 years of testing data analysis, it is found that the corrosion is weak below the inlet of the tail exhaust fan. In order to save costs, after discussion, it was decided that the replacement chimney should be replaced upward from , 25, 19 meters. For those below , 25, 21 meters, anti-corrosion treatment should be carried out during the next kiln shutdown to ensure that the service life matches the newly replaced part. After various understanding, in 2022
10, Yunnan Jianfeng determined the supplier and arrival time of the materials used for replacement through bidding, and worked out a set of construction plan through communication with the hoisting master and the construction team in the early stage: use 600 ton truck crane, and use the inner cylinder to hoist into the construction platform first when dismantling, after cutting 8 wire rope holes and fixing 4 wire ropes, the crane places the construction platform at 1 m below the required slit and fixes it firmly. The cutting can be lifted out. When installing a new chimney, the lowest construction platform is cut for splicing and welding, and so on. Since some iron plates are composite plates, 2.5 mm corrosion-resistant stainless steel plates are bonded to ordinary steel plates. In order to ensure that the stainless steel plates are not damaged, the old breathable cloth is used to be wound on the pressure roller of the plate bending machine for protection. Special lifting workpieces are used in the manufacturing process to ensure that the inner cylinder is not damaged. In order to ensure the welding quality, plates above 10 mm shall be beveled on one side. Each transverse seam and vertical seam shall be welded on both sides and each weld shall be inspected. Only after approval can the next section be hoisted and butted. According to the hoisting scheme, it is divided into 4 sections, and the hoisting weight and construction position corresponding to each section are calculated to control the length. 2 May 3 , the crane was assembled in the factory and dismantled in the afternoon of
4. Due to the difficulty of docking the old and new pipes, the deformation of the original pipe is large, and the docking time exceeds the expected time. For the sake of construction safety, Yunnan Jianfeng communicated with the construction unit and arranged a section of hanging every day to ensure the completion of welding before dark and the withdrawal of personnel. Finally, the replacement of all kiln tail chimneys was completed in the afternoon of . (Lou Xuxin)

Daye Peak Declared 4 Invention Patents Last Year
In 2019, Daye Jianfeng Cement Company changed its thinking, actively explored and tested the use of new materials, and summarized the research results in a timely manner, and successively declared 4 invention patents. In the production process of low-alkali cement, Daye Peak changed the traditional scheme of using high-grade sandstone ingredients alone to replace part of the sandstone and part of the iron correction material with iron ore waste soil, which not only controlled the alkali content in the clinker, but also increased the Al2O3 content in the clinker, ensuring the easy burnability and high early strength of the clinker. Innovation has also been made in the raw material batching scheme, breaking the original high-grade and low-grade sandstones used together and changing them to separate batching of high-grade and low-grade sandstones respectively, thus avoiding the disadvantage of easy material segregation in the process of high-grade and low-grade sandstones used together. At the same time, the original four-component batching is changed to five-component batching, so that low-alkali clinker can be freely switched, which is convenient for production organization and production cost. On the basis of a series of innovative achievements, Daye Peak declared four invention patents in 2019: "a technology for producing clinker from gas sludge and dust collection in steel mills", "a method for treating sludge in machine-made sand mills", "an improvement in raw material batching method" and "a technology for producing low cement from iron ore mining waste soil", all of which have high practical value.
