China's non-ferrous metals and metallurgical industries are traditional industries. Since the 1980s, China has begun to introduce new metallurgical production lines and large-scale equipment. The localization of many vulnerable components such as furnace technology and special refractory materials has become a top priority. The plant has developed a series of research and development for refractory materials and furnace lining structures for non-ferrous metal chemical production processes to produce multi-species and multi-species special unshaped refractories through a variety of process flows and multiple large-scale processes. The introduction of the use of metallurgical equipment has solved a major technical problem that has long plagued the production of non-ferrous metal companies. Its use results and technical indicators have reached advanced levels at home and abroad. Sulfuric acid is an important raw material or auxiliary product in the non-ferrous metal industry, and the preparation of sulfuric acid requires the use of a boiling roaster to produce sulfur dioxide-containing flue gas, the traditional baking furnace life is 3 years. Adopt environment-friendly furnace structure design and special monolithic refractories to replace the traditional brick-building furnace technology, so that the life of the roaster can be increased to more than 20 years, and it is safe and leak-free, basically eliminating the lining overhaul, achieving environmental protection, energy saving, and reducing costs significantly The effect is known as the "green" environment-friendly furnace. China is a big producer of zinc and a major exporter of refined zinc. Zinc alloy production equipment is mainly high-power, large-capacity coreless induction furnace. However, the crucible life of this electric furnace is too short, the longest life is 180 heat, the shortest is only 1 heat, the average is 20 heat. The new type of coreless industrial frequency induction furnace crucible adopts a new cast refractory material that does not need to be sintered. It has excellent thermal shock resistance, high strength, and high resistance to spalling, making the crucible life of the electric furnace reach more than 4800 heats, and Has a strong practicality and promotion value. The grow light fixtures in this category all come with dimmers, which allows for dimming. Plant growers can adjust the illumination according to the needs of different growth stages of the plant, so as to provide the most suitable lighting environment for growth. At the same time, it can be connected to the controller, up to 100 at a time. Synchronous dimming saves time and effort, which is especially suitable for commercial greenhouses.
