What qualifications are required for the construction of lime kiln manufacturers
Lime kiln is a key equipment in the metallurgical industry, and its construction requires strict qualifications from manufacturers. The qualification for general contracting of metallurgical engineering construction is the core qualification. According to the "Qualification Standards for General Contracting of Metallurgical Engineering Construction", this qualification is divided into special grade, first grade, second grade, and third grade. A first-class qualified enterprise with net assets exceeding 100 million yuan, capable of undertaking all metallurgical engineering projects; Second level qualified enterprises can undertake steelmaking, continuous casting and other projects with an annual output of less than 1.2 million tons; Third level qualification enterprises are limited to projects such as steelmaking and steel rolling with an annual output of less than 1 million tons.
In addition to the general contracting qualification, the professional contracting qualification for furnace engineering is also crucial. First level qualification enterprises can undertake various furnace and kiln projects, while second level qualification enterprises are limited to iron smelting blast furnaces with an annual output of 400000 tons or less, coke ovens with an annual output of 300000 tons or less, and other projects.
In addition, the construction of lime kilns involves high-risk processes such as high temperatures and chemical reactions. Manufacturers also need to hold a safety production license to demonstrate their management capabilities in safety technology, fire and explosion prevention, emergency rescue, and other aspects. At the same time, possessing engineering design qualifications, such as professional Grade A design qualifications in the metallurgical industry (coking and refractory materials engineering), can ensure the scientific and compliant design of lime kilns.
