Problems solved by technology
The service life is short and the steel structure cover is easily damaged due to the difficulty of baking and the difficulty of baking
[0004] The shielding cover of VD vacuum furnace with knotted steel structure and refractory material is bulky, the baking is not standardized, the service life is short, and the steel structure cover is easily damaged.
The steel structure of the shielded furnace cover is easily deformed, which reduces the use time; the replacement of the shielded furnace cover of the VD furnace takes a long time and other disadvantages

The invention discloses a VD (Vacuum Degassing) vacuum furnace shielding cover, which is provided with a shielding cover supporting ring (1) and a refractory material shielding cover (2), wherein the shielding cover supporting ring (1) is made of steel and is annular; the refractory material shielding cover (2) is a frustum-shaped cover with a small top and a large bottom; the upper end face and the side face of the frustum are enclosed into a whole, and the lower end face of the frustum is open; and a lower edge opening of the refractory material shielding cover (2) is supported and connected by the shielding cover supporting ring (1). By using the technical scheme, the shielding cover is divided into two parts; the steel structure is effectively separated from the refractory material under the condition of guaranteeing the function of the shielding cover, so that the workload of maintenance, repair and replacement of the steel structure is reduced, meanwhile, the service life of the refractory material is prolonged, and further, the working efficiency of the VD furnace is increased and the workload and the labor intensity of workers are reduced; and through the rationally designed supporting ring structure, overall refractory material shielding cover, hanging ring and locking device, the furnace cover is more convenient and faster to replace and hang.
Description
technical field [0001] The invention belongs to the technical field of metallurgical industry production, and relates to vacuum refining process equipment for steel. More specifically, the invention relates to a VD vacuum furnace shielding cover. Background technique [0002] At present, the shielding cover of VD vacuum furnace in the domestic metallurgical industry generally adopts steel structure. In the prior art, the shielding cover of the VD furnace is an integral structure, the exterior is a steel shell, and the inner lining is masonry or knotted refractory materials. After a period of use, it is damaged and replaced as a whole. Generally, the shell will be replaced after being used for 3 times. The deformation is serious and it is difficult to repair and use again. [0003] Unshaped refractory material is used on the inner wall of the cover, poured and molded, and then put into use. Due to the high difficulty of baking and the high difficulty of baking, the service ...
