作为高炉的附属设备焦炉,用来生产优质冶金焦需要较高的建造费和维修费。因此,荷兰霍戈文公司和英国钢公司进行了以煤代焦的炼铁试验,并提出了熔融还原工艺新建议。霍戈文公司艾莫依登厂和英国钢公司工艺部及Teesside试验室,联合进行了一项用煤炼铁的实验。这种所谓的CBF法(TheConverted Blast Furnace)有两级工序。首先是矿石在竖炉内预还原,接着在气化装置内完全还原和熔化。这是一种直接用原煤作燃料生产液态铁的方法。这种CBF法,不论在工艺设备还是在投资费用方面都有优势。这是因为,原有的高炉设备仍可用于CBF法炼铁。霍戈文公司艾莫依登厂和英国钢公司工艺部及Teesside试验室,将用煤炼铁范畴内各单项的研究工作汇成一个统一的研究项目。这个研究项目就是采用CBF法。采用这种方法,就能以煤作能源材料生产液态铁。CBF法的主要特点是,利用现有的炼铁设备而不使用焦炭,即可用于CBF法炼铁。该项目实施的初期阶段,得到欧洲煤钢联营和欧洲共同体煤气化组织的支持。
As a subsidiary of the blast furnace coke oven, used to produce high quality metallurgical coke requires a higher construction costs and maintenance costs. As a result, the Dutch iron and steel company Hogwow and the British steel coke ironmaking experiments carried out, and proposed a new proposal melting reduction process. A coal-based experiment with coal was conducted jointly with the Hoogwin company Al Moeden Plant and the British Steel Company Process Division and the Teesside Laboratory. The so-called CBF Law (TheConverted Blast Furnace) has two stages. First, the ore is pre-reduced in a shaft furnace and then completely reduced and melted in the gasification unit. This is a direct method of producing liquid iron from raw coal. This CBF method, both in process equipment and investment costs have an advantage. This is because the original blast furnace equipment can still be used for CBF ironmaking. The Hoogwin company Al Moeden Plant and the British Steel Company Process Division and the Teesside Laboratory merge the individual research efforts in the area of coal refining into a single research project. This research project uses the CBF method. Using this method, coal can be used as an energy source to produce liquid iron. The main feature of the CBF method is that it can be used for CBF ironmaking using existing ironmaking equipment without the use of coke. The initial phase of the project was supported by the coal-Europe consortium and the European Community coal gasification organization.
