Abstract
The invention relates to a furnace cover of a split type cast iron vacuum furnace, which is divided into a furnace cover lower part and a furnace cover upper part, wherein the furnace cover lower part is a cover ring, the furnace cover upper part is a cover top, and the furnace cover lower part and the furnace cover upper part are positioned and overlapped; more than three mounting lifting lugs are arranged on the side of the lower part of the furnace cover; and the top surface of the upper part of the furnace cover is provided with an air vent and an observation hole. The furnace cover of the split type cast iron VD vacuum furnace is divided into a lower part and an upper part, the lower part and the upper part are positioned and overlapped, the lower part and the upper part form a furnace cover whole body through the positioning and overlapping when in use, the furnace cover can be normally installed and used, the upper part or the lower part is replaced according to the degree of the melting loss influence of the furnace cover after the furnace cover is used, and the furnace cover is convenient to implement and operate, economical and effective. Practice proves that the method of replacing the integral VD furnace cover with the split VD furnace cover is a better method.
Description
Technical Field
The invention belongs to the metallurgical casting industry, and particularly relates to a furnace cover of a split type cast iron VD vacuum furnace.
Background
In metallurgical production, the furnace cover of a cast iron VD vacuum furnace is widely applied as a common metallurgical appliance. Generally, when the furnace cover of the VD vacuum furnace is used, the top of the furnace cover is easily melted and damaged compared with other parts due to the influence of a heating environment, so that the furnace cover of the VD vacuum furnace loses effectiveness and is discarded. The VD vacuum furnace cover scrapped due to the failure of the melting loss of the top part is still intact at other parts, only the melting loss part is difficult to repair, so that the whole vacuum furnace cover is scrapped, and the feeling is pitot and uneconomical.
In view of the above, the search for a split type cast iron VD vacuum furnace cover is a pursued goal of those skilled in the art.
Disclosure of Invention
The invention aims to provide a split type cast iron VD vacuum furnace cover, which is divided into a lower part and an upper part, wherein the lower part and the upper part are positioned and overlapped, the lower part and the upper part are positioned and overlapped to form a whole furnace cover when in use, the furnace cover can be normally installed and used, and the upper part or the lower part is replaced according to the degree of melting loss influence after the furnace cover is used, so that the problem that the whole furnace cover of the vacuum furnace in the prior art is only scrapped due to the failure of melting loss of the top is solved.
The technical solution of the invention is as follows:
a split type cast iron vacuum furnace cover is divided into a lower part and an upper part, wherein the lower part of the furnace cover is provided with a cover ring, the upper part of the furnace cover is provided with a cover top, and the lower part of the furnace cover and the upper part of the furnace cover are positioned and overlapped;
more than three mounting lifting lugs are arranged on the side of the lower part of the furnace cover;
and the top surface of the upper part of the furnace cover is provided with an air vent and an observation hole.
The part for positioning and overlapping between the lower part of the furnace cover and the upper part of the furnace cover is connected with an embedded notch.
The part for positioning and overlapping between the two parts of the lower part of the furnace cover and the upper part of the furnace cover is connected by embedded convex points.
The furnace cover of the split type cast iron VD vacuum furnace is divided into the lower part and the upper part, the lower part and the upper part are positioned and lapped, the lower part and the upper part form the whole furnace cover through the positioning and lapping in use, the furnace cover can be normally installed and used, the upper part or the lower part is replaced according to the degree of the melting loss influence of the furnace cover after the furnace cover is used, and the furnace cover is convenient to implement and operate, economical and effective.
The split type cast iron vacuum furnace cover is used in metallurgical production occasions using the VD vacuum furnace, the shape of the VD furnace cover is not integrally changed by the furnace cover, the normal implementation of casting technology is not influenced, the operation is convenient, and the practical effect is relatively ideal. Practice proves that the method of replacing the integral VD furnace cover with the split VD furnace cover is a better method.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and examples.
Referring to fig. 1 and 2, the invention provides a furnace cover of a split type cast iron VD vacuum furnace, which is divided into a furnace cover lower part 1 and a furnace cover upper part 3, wherein the furnace cover lower part 1 is a cover ring, the furnace cover upper part 3 is a cover top, and the furnace cover lower part 1 and the furnace cover upper part 3 are positioned and overlapped. The parts of the positioning and overlapping between the lower part 1 of the furnace cover and the upper part 3 of the furnace cover are connected by an embedded notch or an embedded convex point.
More than three installation lifting lugs 2 are arranged on the side of the lower part 1 of the furnace cover, so that the furnace cover is convenient to hoist. The top surface of the upper part 3 of the furnace cover is provided with a vent hole 4 and an observation hole 5.
When the vacuum furnace cover is used, the lower part of the furnace cover and the upper part of the furnace cover are connected through positioning to form a whole body of the VD vacuum furnace cover made of cast iron, the vacuum furnace cover can be normally installed and used, the upper part of the furnace cover or the lower part of the furnace cover is replaced according to the degree of melting loss influence of the furnace cover after the vacuum furnace cover is used, and the vacuum furnace cover is convenient to implement and operate, economical and effective.
Of course, those skilled in the art will recognize that the above-described embodiments are illustrative only and not intended to be limiting, and that changes, modifications, etc. to the above-described embodiments are intended to fall within the scope of the appended claims, provided they fall within the true spirit and scope of the present invention.
