Galvalume steel is also called Aluminum-Zinc Alloy Coated Steel, Zincalume steel, aluminized zinc steel (aluzinc steel), SGLC. The galvalume metal is composed of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at a high temperature of 600 ° C. Its whole structure consists of aluminium-iron-silicon-zinc, forming a dense quaternary crystal of an alloy.From the point of view of the degree of coating, the Galvanized Steel Coil is mainly the zinc plated on the coating, while the coating of the galvalume Steel Coil not only has zinc, but also has an extra part of aluminum.Galvalume steel sheet (coil) has better atmospheric corrosion resistance.
Galvalume Steel Sheet has excellent characteristics: strong corrosion resistance, 3 times that of pure Galvanized Steel Sheet; the surface has beautiful spangles, which can be used as building exterior panels.
The corrosion resistance of "Galvalume Steel Coil" is mainly because of aluminum, the protective function of aluminum. When the zinc is worn away, the aluminum forms a dense layer of aluminum oxide, preventing corrosion-resistant substances from further corroding the interior.

The 400,000-ton/year calcium carbide project is one of the key tasks for the Dalate branch in 2009. Since the project began construction on April 22, it has received high attention from all parties. Dalian Heavy Industries Lift Group Co., Ltd., as the task of assuming the project EPC's total package, gave high priority to the project. Song Jiajing, Chairman of Dalian Crane Lift Group Co., Ltd. personally led the project and strengthened the human, material, and managerial strengths, and successively assigned 4 A senior company leader went to the site to supervise the project. Wang Wancai, deputy manager of the general branch of the Dalate branch, explained that Chairman Wang Wenji of Yili Resources Group paid high attention to the 400,000 tons/year calcium carbide project and visited the construction site almost every half month, and he gave supervision on existing problems on site. , to ensure the rapid progress of the project.
In addition, the mutual assistance and frank communication between the owners, the general contractor, the construction unit, and the supervision company, and the solution to the emergence of positive and effective measures are the key to advancing the progress of the project and ensuring the quality of the project. According to Wang Wancai's deputy manager, from the beginning of August till now, the on-site dispatching meeting was held at 6:30 in the morning for 3 consecutive months to coordinate and solve the problems existing in the implementation process of the day. The supervision units performed their duties and actively stationed at the project site and entered the construction site daily. The on-site supervision of the construction unit also ensures the quality of the project.
As an important supporting project for the 400,000-ton/year calcium carbide project, the construction progress of the 110-kilovolt-edge point station is directly related to the commissioning of the entire project. Therefore, at the same time that 400,000 tons/year of calcium carbide project was started, the construction of the 110 kV variable-voltage station was put on the agenda at the same time. Negotiations with the Inner Mongolia Electric Power Design Institute began in May; preliminary design plans were signed in July; separate bids for transformers, transformers, circuit breakers, control cabinets and other large equipment and construction units began to be carried out in August. In late September, the 110-kilovolt change-over point station was officially started construction. As of the beginning of December, the foundations and towers of the substation line have been completed, and the separation and contact structure of the Minan Power Plant has been completed.
The reporter saw in the construction site of 400,000 tons/year calcium carbide project that there are many young faces in the project area. It is reported that this is the newly recruited employees who are familiar with the equipment. It is understood that the employees of the calcium carbide industry are unusually heavy, which results in a shortage of workers and an embarrassing situation of low levels of workers' skills and qualities. To enable the 400,000-ton/year calcium carbide project to be successfully produced, on September 1st last year, the Dalate branch recruited 310 graduates from colleges and universities in Hohhot, Yulin, Baoji, etc. The meticulous pre-job training was sent to Jiangsu and other places for internships to ensure that they have a certain level of employment.
Annual production of 400,000 tons of calcium carbide project will be completed in Yili Group Dalat Branch
After a brief construction period of 8 months, the 400,000-ton/year calcium carbide project of the Dalate branch of the Yili Group will be commissioned on the 20th of this month. At present, the project has entered the final stage of equipment commissioning.
