Abstract
An object of the utility model is to provide a vacuum induction furnace is ingot mould for casting, include: go up mesa, overhead hoist and mould body down, there is a die cavity inside the mould body, and the mould body adopts HT200, and the die cavity is big-end-up's circular cone, and the longitudinal section is trapezoidal, and the cross section is circular, goes up the circle diameter and is 130mm, and the circle diameter is 110mm down, and inner wall roughness Ra is 3.2, and steel ingot weight can reach 25kg after the casting. The weight of the steel ingot is increased by optimizing the height-width ratio, the length of the effective section of the rolled steel plate is increased, and the sampling number of samples is increased. Meanwhile, the roughness of the inner wall of the ingot mould is reduced, so that the solidified ingot is easier to demould.
Description
Technical Field
The utility model discloses mainly apply to the vacuum induction furnace and smelt the field, specifically be a ingot mould is used in vacuum induction furnace casting.
Background
The ingot mold is a cast iron mold by which molten steel is solidified. The ingot mould is a necessary product for smelting and casting in a vacuum furnace, and has important influence on the surface and internal quality of the steel ingot and the cost of the steel ingot. The consumption of the ingot mould is an important technical and economic index of pilot smelting production.
Previously, the ingot moulds used in pilot plant bases have been of low height, relatively large width, unsuitable aspect ratio and poor internal quality of the cast ingot. And the maximum weight of the cast steel ingot is 22kg, the total length of the rolled steel plate is short, after a dead head and the bottom are cut off, the effective use section is short, the sampling part is limited, the number of samples which can be processed into mechanical property, physical property and chemical property is small, and the influence on the pilot test experiment process of steel grade development is large.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a vacuum induction furnace is ingot mould for casting.
An object of the utility model is to provide a vacuum induction furnace is ingot mould for casting, include:
the steel ingot casting mould comprises an upper table top, a lower table top, a lifting device and a mould body, wherein a cavity is arranged in a shell, and the steel ingot casting mould is characterized in that the mould body is HT200, the cavity is a conical table with a large upper part and a small lower part, the longitudinal section is trapezoidal, the cross section is circular, the diameter of an upper circle is 130mm, the diameter of a lower circle is 110mm, the roughness Ra of the inner wall is 3.2, and the weight of a cast steel ingot can reach 25 kg.
Compared with the prior art, the utility model provides a vacuum induction furnace is ingot mould for casting has following advantage:
on the basis of the existing ingot mould, the height and the width of the ingot mould are optimized to obtain a reasonable and proper height-width ratio, the internal quality of the steel ingot is improved, and the weight of the steel ingot is increased, so that the effective section length of a rolled steel plate is increased, and the sampling number of samples is increased. Meanwhile, the roughness of the inner wall of the ingot mould is reduced, so that the solidified ingot is easier to demould.

Detailed Description
In order to make the technical field better understand the solution of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings and the detailed description.
In a particular embodiment, the present invention provides an ingot mould for casting in a vacuum induction furnace. Referring to fig. 1, there is shown a structure of an ingot mold for casting in a vacuum induction furnace according to an embodiment of the present invention.
The embodiment of the utility model provides a vacuum induction furnace is ingot mould for casting, include:
the steel ingot casting mould comprises an upper table top, a lower table top, a lifting device and a mould body, wherein a cavity is formed in the shell, the mould body is HT200, the cavity is a truncated cone with a large upper part and a small lower part, the longitudinal section is trapezoidal, the cross section is circular, the diameter of an upper circle is 130mm, the diameter of a lower circle is 110mm, the roughness Ra of the inner wall is 3.2, and the weight of a cast steel ingot can reach 25 kg.
(1) Die body
The mold body adopts HT200, a cavity in the steel ingot is a truncated cone with a large upper part and a small lower part, the diameter of an upper circle is 130mm, the diameter of a lower circle is 110mm, the roughness Ra of the inner wall is 3.2, and the weight of the steel ingot after casting can reach 25 kg.
(2) Upper and lower table top
In order to conveniently place a riser and a sprue on the ingot mould and increase the stability of the ingot mould, disk surfaces with the diameter of 230mm are added at the upper end and the lower end of the mould body, and the surface roughness Ra is 6.3.
(3) Hoisting device
In order to facilitate the hoisting and the transportation of the solidified ingot mold and the solidified ingot from the vacuum furnace, hoisting devices are additionally arranged on the left side and the right side below the upper circular truncated cone. This overhead hoist structure is that the cylinder adds the fender dish, and the cylinder diameter is 30mm, and length is 35mm, and the fender dish diameter is 50mm thickness and is 10 mm. The ingot mould is stably and smoothly lifted, and the unhooking of the steel wire rope can not occur, thus causing accidents.
The weight of the steel ingot is increased by optimizing the height-width ratio, the length of the effective section of the rolled steel plate is increased, and the sampling number of samples is increased. Meanwhile, the roughness of the inner wall of the ingot mould is reduced, so that the solidified ingot is easier to demould.
The above is to the detailed introduction provided by the present invention. The principles and embodiments of the present invention have been explained herein using specific examples, and the above descriptions of the embodiments are only used to help understand the method and its core ideas of the present invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and such modifications and modifications also fall within the protection scope of the appended claims.
