Embodiment Construction
[0019] The invention relates to a cooling device and a cooling method for a titanium sponge reduction distillation container. The cooling device and the cooling method not only have a fast cooling speed for the reduction distillation container, but also prevent oxidation and corrosion of the reduction distillation container, and are more effective for the reduction distillation. The container does not produce chilling deformation.
[0020] Set the outer diameter of the container of the reducing distillation vessel 11 as D and the outer diameter at the flange of the container mouth as D 1 , set the maximum depth of the reduction distillation vessel 11 as H, and the reduction distillation vessel 11 stores the spongy titanium lump generated by the reaction.
[0021] The present invention can be explained in more detail through the following examples. The present invention is not limited to the following examples. The purpose of disclosing the present invention is to protect all c...

The invention provides a cooling device and a cooling method for a titanium sponge reduction distillation container. The cooling device comprises a lower rib plate (1), a direct water inlet gate valve (2), a sleeve plate (3), an indirect water inlet gate valve (4), a water jacket (5), an upper rib plate (6), an upper flange (7), an indirect water outlet gate valve (8), a direct water outlet gate valve (9), a cooling barrel (10), a base plate (12), a direct water discharge gate valve (13) and a lower flange (14). In the process of initial-stage cooling, the reduction distillation container (11) does not directly contact cooling water, so high temperature oxidation of the cooling barrel caused by the high temperature of the reduction distillation container is avoided, chilling deformation damage caused by direct cooling of the reduction distillation container by the cooling water is avoided, the reduction distillation container is protected, and it is guaranteed that a safety product of a spongy titanium lump is obtained; and in the process of later-stage cooling, the reduction distillation container is soaked in the cooling water, and the reduction distillation container and the spongy titanium lump are simultaneously cooled.
Description
technical field [0001] The invention belongs to the technical field of smelting, in particular to a cooling device and a cooling method for a titanium sponge reduction distillation vessel. Background technique [0002] Sponge titanium is the primary raw material in titanium alloy smelting. At present, the main method for industrial production of sponge titanium is the Kroll method, which uses Mg and TiCl in the reduction distillation vessel 4 The reduction reaction produces Ti, and then the excess Mg and the reaction product MgCl are removed by high-temperature vacuum distillation using a reduction distillation furnace. 2 and a small amount of titanium chloride to finally obtain a spongy titanium lump. The spongy titanium lump should be cooled in the reduction distillation furnace along with the reduction distillation vessel. After cooling to a certain temperature, the reduction distillation vessel is lifted into the cooling device to continue cooling. After cooling to norm...
