We provide intelligent technological control systems with independent intellectual property rights, ranging from the basic automation for reheating furnaces to intelligent management for the reheating furnace workshop. They allow our customers to realize target management of the steel billets throughout the entire reheating process, flexible organization of production process, equipment management, energy balance analysis and other functions to be tailor-made according to the specific needs of the customers.
By extensively using the CAE simulation technology, we have established analysis model for the whole reheating furnace, which can comprehensively and accurately analyze the reheating furnace temperature fields, flow fields and pressure fields in various design schemes.
The waste heat that is not easy to be recovered in industrial production can be systematically and comprehensively recovered through thermal technology to achieve the purpose of energy saving and consumption reduction. After years of research and experimentation, we have developed successfully the technology of recovering the sensible heat from hot metallurgical slag by which the sensible heat of metallurgical slag of 1,450C can be recovered and reutilized, with vitrification rate of granulated slag above 93%, and no generation of wastewater and waste gases.
The high-efficiency combined cascade waste heat recovery allows ultimate recovery and reutilization of the waste heat from the flue gas. It also includes the technologies of high-efficiency air and gas preheating, flue gas waste heat boiler and skid & column vaporization cooling.
We have been focusing on the development energy efficiency technologies and their applications to the real projects. By taking into account the characteristics of comprehensive utilization and co-generation of the secondary energy from the captive power plants in the metallurgical industry, we have developed our high-efficiency and environmentally-friendly power generation technologies, such as subcritical, ultra-high-temperature and ultra-high-pressure, high-temperature and ultra-high-pressure thermal power generation, miniaturized, switching from one to other fuels, co-generation of heat, power and air with multiple drives, low-calorific-value gas-steam combined cycle power generation, high-efficiency integrated desulfurization and denitration, etc. They can bring significant economic and social benefits to the thermal power plants projects in the metallurgical industry, with relatively lower capital expenditure, higher output, lower waste emission.
We are committed to achieving production and reasonable control, use of the industrial gas in all aspects of the metallurgical production process: industrial gas balance and benchmarking control of gas consumption in the whole plant; the characteristics of industrial gases and their effects on the cleaning system and combustion utilization system and equipment; cost-effective cleaning, fluctuation analysis, storage and distribution of the surplus gas; gas safety and investment control. We have developed our comprehensive technologies of industrial gases in the metallurgy industry, which help our customers achieve the best cascade utilization of the industrial gases to maximize the utilization level of gas, power self-sufficiency and economic benefit of the whole plant.
The direct-reducing rotary hearth furnace is designed to reduce the metallurgical sludge mixed with carbon directly to metallized pellets. It is suitable for treating zinc-containing slurry and sludge, thus solving the problem of zinc enrichment and alkali metal enrichment at iron & steel enterprises, thus realizing comprehensive utilization of iron, carbon and zinc. It is also able to treat V-Ti ores, iron sand, copper slag, nickel slag, etc., to facilitate iron enrichment and recovery of precious metals.
