Abstract
The utility model discloses an kind of continuous casting is opened and is watered leak protection dummy ingot device, including the steel sheet, set up the through-hole that link up its upper and lower terminal surface on the steel sheet, the dummy ingot round pin, the pinhole has been seted up to the end of dummy ingot round pin, the ingot round pin inserts perpendicularly in the through-hole of steel sheet, the dummy ingot round pin passes through welding sealing connection with the steel sheet, during the use, the end that the steel sheet was equipped with the pinhole inserts the dummy ingot head and stretches out from the dummy ingot head, the steel sheet all around the size be greater than or equal to the terminal surface size of dummy ingot head towards the steel sheet, and the steel sheet all around with cast crystallizer copper pipe clearance fit, solved former dummy ingot device and easily followed the shortcoming of dummy ingot head steel leakage, reduce the production accident, asbestos cord consumption reduces two thirds, reduces artifical stopper dummy ingot work, shortens the preparation time before opening and waters, the utility model discloses simple manufacture, practicality.
Description
Technical Field
The utility model belongs to the technical field of metallurgical engineering, a continuous casting is opened and is watered operation is related to, concretely relates to kinds of continuous casting are opened and are watered leak protection dummy ingot device.
Background
Continuous casting is slowly changed, casting start is added into , the continuous casting is conveyed into a lower opening of a crystallizer for fixing the height through a dummy bar, gaps around the dummy bar and a copper tube of the crystallizer and gaps of a dummy bar pin are manually filled, molten steel flows into the crystallizer after casting start, a primary blank shell is formed in the crystallizer through the cooling effect of the copper tube of the crystallizer, the molten steel is in contact with the head of the dummy bar and an added cold steel strip and then is connected to , the dummy bar is driven by a withdrawal and straightening machine to pull a red blank out of the crystallizer, the head of the dummy bar is separated from the dummy bar pin through an automatic jacking device after the dummy bar is taken out of the withdrawal and straightening machine, so that a casting blank is separated from the dummy bar, the dummy bar pin is connected to , and continuous casting of the molten steel is realized through continuous supplement of the molten steel and continuous withdrawal of.
A blind area exists in the design of a dummy bar head used in the prior continuous casting, namely a gap exists between a dummy bar pin and the dummy bar head due to movable connection, a large amount of asbestos is needed for filling, molten steel is solidified fast due to the action of a crystallizer water-cooling copper pipe after the periphery of the dummy bar and a crystallizer are filled, the molten steel is not easy to flow out to cause a steel leakage accident, the molten steel between a dummy bar and the dummy bar pin is not sufficiently cooled, the downward pulling force of a tension leveler is easy to cause the molten steel leakage at the position, the steel leakage slightly causes the adhesion of a billet and the dummy bar at to cause the automatic detachment of the dummy bar, and the steel leakage is serious to cause the production interruption.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model aims to solve the technical problem of providing leakproof dummy ingot devices.
The technical proposal adopted by the utility model for solving the technical problems is that continuous casting leakage-proof dummy ingot devices comprise:
the steel plate is provided with a through hole penetrating through the upper end surface and the lower end surface of the steel plate;
the end of the dummy bar pin is provided with a pin hole, the dummy bar pin is vertically inserted into the through hole of the steel plate, and the dummy bar pin is hermetically connected with the steel plate through welding, so that molten steel is prevented from entering a gap between the dummy bar pin and a dummy bar head.
When the device is used, the end, provided with the pin hole, of the steel plate is inserted into the dummy bar head and extends out of the dummy bar head, the peripheral size of the steel plate is larger than or equal to the end face size of the dummy bar head towards the steel plate (the purpose is to ensure that the steel plate completely covers the dummy bar head so as to prevent molten steel from entering a gap between the dummy bar pin and the dummy bar head), and the periphery of the steel plate is in clearance fit with a copper pipe of a cast crystallizer (the gap is preferably 5 mm).
The end of the dummy bar with a pin hole is extended out from the dummy bar head and is directly connected with the dummy bar through a pin inserted into the pin hole, thus being convenient for use.
Compared with the prior art, the beneficial effects of the utility model are that the utility model discloses a continuous casting is opened and is watered leak protection dummy ingot device covers the dummy ingot head through the steel sheet, pull the operation after making the molten steel solidify through the forced cooling effect of crystallizer copper pipe simultaneously through adding partial cold billet, need not a large amount of asbestos and fills the clearance between dummy ingot round pin and the dummy ingot head, solved and leaked the dummy ingot accident, solve the unable automatic dummy ingot accident that takes off that leads to because of leaking the dummy ingot.

Detailed Description
The utility model discloses below combine the embodiment to do step details:
specifically, the continuous casting start-up casting leakage-proof dummy ingot device comprises a steel plate and a dummy ingot pin, wherein the steel plate is provided with a through hole penetrating through the upper end face and the lower end face of the steel plate, the end of the dummy ingot pin is provided with a pin hole, the ingot pin is vertically inserted into the through hole of the steel plate, the dummy ingot pin is hermetically connected with the steel plate through welding to ensure that the dummy ingot head is completely covered and prevent molten steel from entering a gap between the dummy ingot pin and the dummy ingot head, when the device is used, the end, provided with the pin hole, of the steel plate is inserted into the dummy ingot head and extends out of the dummy ingot head to be connected with a dummy bar, the peripheral dimension of the steel plate is the same as the dimension of the end face, facing the steel plate, of the steel plate, and the casting gap of a copper pipe of a crystallizer is 5 mm.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
