Description

A slab crystallizer corner seam cleaning tool

technical field

The utility model belongs to the technical field of continuous steel casting devices, in particular to a tool for cleaning corner seams of copper plates of slab crystallizers.

Background technique

With the requirements of technological progress, continuous steel casting has become a common steel production mode. In continuous casting, the mold is an important equipment. The molten steel is formed in the mold, and the quality of the mold directly affects the quality of the billet. quality. In the process of production and use, steel flow or mold slag is often splashed into the corner seam of the mold copper plate, and the corner seam is bonded after cooling, which affects the normal production of continuous casting. Since the mold copper plate corner seam is small, this kind of bonded It is difficult to remove the sundries, resulting in large corner seams of the copper plate of the crystallizer, and large corner seams of the copper plate of the crystallizer may easily lead to steel breakout accidents caused by clamping steel. At present, there is no special tool on the market to clean the corner joints of the copper plate of the crystallizer. Usually, steel braze or feeler gauge is used to remove it. The disadvantage is that the cleaning is not clean, it is very inconvenient to use, and it is easy to damage the surface of the copper plate of the crystallizer, and at the same time affect the crystallizer. service life.

Utility model content

In order to overcome the above-mentioned shortcomings of the prior art , the utility model provides a slab crystallizer angle seam cleaning tool, the oiler has a hand-held rod, a connecting rod and a scraper, and is reusable, simple in structure, and low in cost. lower features.

The technical scheme adopted by the utility model to solve the technical problem is: a slab crystallizer angle seam cleaning tool, including a hand-held rod, a connecting rod and a scraper, the hand-held rod is made of rigid materials, and the middle part of the hand-held rod is welded to the top of the connecting rod Fixed connection, the connecting rod is made of rigid material, and the end of the connecting rod and the end of the scraper without a knife edge are fixedly connected by welding. The scraper is a square structure with a knife edge at the outer end.

The beneficial effect of the utility model is: it can be used to clean the four corner seams of the copper plate of the crystallizer, effectively prevent the corner seam of the mold from adhering to mold slag or cold steel and other sundries and cause the corner seam to be too large, and at the same time prevent the corner seam from being too large The cold steel that causes bonding in the crystallizer will affect the quality of the slab and even lead to the occurrence of steel breakout accidents due to the cold steel clamped during pouring. It has the characteristics of reusable, simple structure and low cost.

Description of drawings

Fig. 1 is the front view of the utility model.

Fig. 2 is a top view of the utility model.

In the figure: 1-hand-held rod, 2-connecting rod, 3-scraper.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Referring to Fig. 1, a tool for cleaning corner seams of a slab crystallizer includes a hand-held rod 1, a connecting rod 2 and a scraper 3, the hand-held rod 1 is made of rigid material, the middle part of the hand-held rod 1 is fixedly connected to the top of the connecting rod 2 by welding, and the connection The rod 2 is a rigid material with a certain length, and the end of the connecting rod 2 is fixedly connected to the edge-free end of the scraper 3 by welding. The scraper 3 is a square structure with a knife edge at the outer end.

The utility model can be used to clean the four corner seams of the crystallizer copper plate, effectively preventing the corner seams of the crystallizer from adhering to mold slag or cold steel and other sundries, causing the corner seams to be too large, and at the same time preventing the corner seams from being too large to cause sticking in the crystallizer. The cold steel that is knotted will affect the quality of the slab, and even the cold steel will cause a steel breakout accident during pouring. It has the characteristics of reusable, simple structure and low cost.
