Abstract
The utility model provides an argon joint protection device, comprising a metal casing. The protection device is characterized in that the protection device has a left metal casing and a right metal casing which are closed together in symmetry; the inner side of each metal casing is fixed with a thermal insulation lining with the inner side in a semicircular shape, so as to form a protective cover; the length of the protective cover is greater than that of an argon joint; the inner side of the thermal insulation lining fits the outer side of the argon joint; the outer side of each metal casing is fixed with a handle; both the upper edge and the lower edge of each metal casing are welded with axis pin pipes; and the two metal casings are articulated together by inserting axis pins in two corresponding axis pin pipes on one side, and the axis pins are inserted in the axis pin pipe on the other side as well. The argon joint protection device can effectively protect the argon joint, so as to prolong the service life of the argon joint.
Description
Technical field
The utility model relates to the argon gas connector protection device of argon gas pipeline junction in a kind of metallurgy industry VD stove vacuum chamber.
Background technique
Argon system in metallurgy industry VD stove vacuum chamber at present; in vacuum; because argon gas rapid pipe joint place only curves metal covering as the argon gas connector protection device with a metal baffle; the high temperature slag that the VD stove overflows often drops on the argon gas joint; so that burn out the argon gas joint, not only waste argon gas and change the argon gas joint again.The metal plate washer also needs frequent replacing; and do not reach the effect of effective protection argon gas rapid pipe joint; shorten the working life of argon gas joint; every stove steel is with an argon gas joint; so need often to change argon gas rapid pipe joint, increase cost, and influence the argon flow amount in the VD stove evacuation process; influence VD stove evacuation effect, thereby influence the internal soundness of molten steel.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing argon gas connector protection device, the utility model provides a kind of argon gas connector protection device, scaling loss argon gas joint when the high temperature slag that this argon gas connector protection device can avoid the VD stove to overflow falls.
The purpose of this utility model is to realize like this; by two inner side surfaces is that segmental tile shape safety cover vertically is hingedly connected together and constitutes the argon gas connector protection device; the internal diameter of safety cover and argon gas joint external diameter match; there is the metallic case of semicircle or semicircular in shape in the safety cover outside; respectively welding a handle in the metallic case outside, the insulation lining of thermal insulating material is being fixed in the metallic case inboard.The length of safety cover is greater than the argon gas length of said joint, at respectively welding up and down of two metallic cases be used to the to be articulated and connected bearing pin pipe of usefulness.In actual use, ladle advances before the VD hole, with the argon gas connector protection device argon gas joint is encased, and inserts bearing pin at the bearing pin pipe argon gas connector protection device is fixed.The high temperature slag that the rapid pipe joint of protection argon gas is not overflowed in VD stove evacuation process burns out.For the VD stove provides stable argon gas, to guarantee steel quality.
This argon gas connector protection device comprises metallic case; it is characterized in that: it has two symmetrical metallic cases that lump together; fixing the inboard semicircular insulation lining formation safety cover that is in each metallic case inboard; the length of safety cover is greater than the argon gas length of said joint; the inboard of insulation lining and the outside of argon gas joint match; handle at each metallic case outer fixing; the bearing pin pipe is all welding in top and bottom at metallic case; two metallic cases are being inserted bearing pin by on one side the bearing pin pipe of two correspondences wherein and are being hingedly connected together, and are also inserting bearing pin at a bearing pin pipe of another side.
Because this argon gas connector protection device adopts such scheme; in the VD processing procedure, the argon gas joint is encased with this argon gas connector protection device; can protect the argon gas joint effectively; prolonged the working life of argon gas joint; general three stove steel are with an argon gas joint; and stopped the leakage of argon gas, reduced the steel-refining cost in the VD processing procedure.
