本发明属于冶金技术领域,具体涉及一种电炉冶炼装置的加料装置及其加料方法。 The invention belongs to the technical field of metallurgy, and particularly relates to a feeding device of an electric furnace smelting device and a feeding method thereof.
背景技术Background technique
电炉冶炼是一种重要的炼钢方法,在冶炼过程中,原料加入电炉的环节直接影响生产环境和电能消耗,电炉生产中最典型和普遍的是料篮直接对炉堂加料,但生产环境极其恶劣,为改善生产环境和降低电耗,出现了向电炉内快速密闭加料的技术,该技术是一种在电炉生产中节能降耗及环保的技术。 Electric furnace smelting is an important steelmaking method. In the smelting process, the process of adding raw materials to the electric furnace directly affects the production environment and electric energy consumption. The most typical and common in electric furnace production is that the basket is directly fed to the furnace, but the production environment is extremely Poor, in order to improve the production environment and reduce power consumption, there has been a technology of rapidly sealing the feed into the electric furnace. This technology is a technology that saves energy and reduces environmental consumption in the production of electric furnaces.
在对某些原料加料时,电炉的密闭加料技术的实施具有很大的难度,实施的可靠性也较低,如废钢冶炼生产的加料,由于废钢尺寸形状特异,加料难度大,可靠性低。分析现有技术,中冶赛迪申请号为201020187991.6和201010170509.2的专利'一种短流程废钢预热输送装置'中提出了一种加料技术,该技术提出了对电炉加料的'集装箱'理念,但采用了底开料槽对加料长槽的加料方式。上述技术主要的问题是:长的底开料罐打开底门的可靠性较低,存在影响生产效率的较高概率事件,对加料长槽加料多了一个生产环节,加料长槽中铺料厚度不好掌控而影响后续废钢的输送处理,以及会对加料长槽料产生冲击造成不利影响。 When feeding certain raw materials, the implementation of the closed feeding technology of the electric furnace is very difficult, and the reliability of the implementation is also low.

The main problems of the above technology are: the low bottom open tank has low reliability to open the bottom door, and there is a high probability event affecting the production efficiency. There is one more production step for feeding the long trough, and the thickness of the feed in the long trough is increased. It is not easy to control and affect the transportation of the subsequent scrap, and it will have an adverse impact on the impact of the feed material.
针对上述不足,需研制一种用于向电炉中加入废钢的快速加料装置及其加料方法,提高废钢加料效率并增加加料的可靠性,同时,也使加料长槽中的铺料厚度易于掌控并避免加料长槽受到冲击,延长其使用寿命。 In view of the above shortcomings, it is necessary to develop a rapid feeding device for adding scrap steel to an electric furnace and a feeding method thereof, thereby improving the scrap feeding efficiency and increasing the reliability of feeding, and at the same time, the thickness of the paving in the feeding long groove is easy to control and Avoid feeding long grooves and shocking them to prolong their service life.
