一、电弧炉电弧炉主要由炉壳、炉盖、倾动机构、电极升降机构等机械设备以及电气设备组成。 1、炉壳包括圆筒形炉身、炉底和上部加固圈三部分。通常用12～30毫米钢板焊成。为防止受热变形,通常采用槽钢加固,大炉子采用水冷措施。炉壳上设有炉门和出钢口。出钢口的流钢槽应尽可能短些,以减少出钢时钢水二次氧化和热量损失。 2、炉盖由炉盖圈和砌于炉盖圈内的耐火砖组成。炉盖圈通常用钢板或型钢焊成,一般采用水冷。炉盖与炉壳间必须密封。盖上设有三个电极孔并装有水冷的电极密封圈。 3、倾动机构在我国电弧炉新系列中已多
First, the EAF EAF mainly by the furnace shell, furnace cover, tilting mechanism, electrode lifting mechanism and other mechanical equipment and electrical equipment. 1, the furnace shell includes a cylindrical furnace, furnace bottom and upper reinforcement ring three parts. Usually welded with 12 to 30 mm steel plate. In order to prevent the deformation of the heat, usually using channel reinforcement, large furnace water-cooled measures. Furnace shell with furnace door and tapping hole. The tapping groove should be as short as possible to reduce secondary oxidation and heat loss during tapping. 2, the lid by the furnace lid circle and the refractory bricks in the furnace cover circle. Hearth ring usually welded steel plate or steel, the general use of water-cooled. Gland and furnace shell must be sealed. Cover with three electrode holes and equipped with water-cooled electrode seals. 3, tilt mechanism in our new series of arc furnace has more
