The tundish is a refractory container which receives molten steel poured from a ladle and then distributes the molten steel to each crystallizer through a tundish upper nozzle. The overall structure of the tundish mainly comprises a ladle body, a ladle cover, a stopper rod and a water inlet, wherein the refractory lining consists of a heat insulation layer, a permanent layer and a working layer, the working layer is directly contacted with high-temperature molten steel, and the manufacturing requirement is high, in particular to the thickness and uniformity of the working layer of the tundish. When the working layers of the tundish are manufactured, the positioning of the moulding bed is not correct, and the thickness of the working layers at the two sides of the tundish is inconsistent. In the production process, one side of the tundish working layer, which is relatively thin, is easy to erode too fast, so that the service life of the tundish is directly shortened, and when the erosion of the working layer is serious, serious safety production accidents such as the penetration of the tundish, the outflow of molten steel out of the ground and the like can be caused.
According to the technical specification manufacturing process requirement, the thickness of the working layer of the currently manufactured tundish is required to be 60mm. In the present price section, when the tundish working layer is manufactured, the thickness of the working layer mainly depends on a tire mold positioning rod with the diameter of 60mm, and the thickness of the working layer is controlled by the equivalent thickness. The material of the positioning sticks of the tire mold is round wood sticks with the same size, the required length of the wood sticks is 1200mm, and the diameter of the wood sticks is 60mm.
The tundish manufactured by using the tire mold positioning rod has the main defects that:
1. the forming die is used for positioning the wood rod to be soft, and the wood rod can deform after being used for many times, so that the thickness of the wood rod is thinned, and the thickness of a working layer of the tundish is directly influenced.
2. The mould location stick is circular, can not effectively fix, can walk the position when putting into the mould and adding the dry-type material, causes the mould to put incorrectly, leads to middle package both sides working layer thickness inconsistent, inhomogeneous, and thinner department corrodes too fast, influences middle package life.
3. The tundish has short service life, the upper limit of the number of continuous casting furnaces is 20 furnaces, the continuous casting time is only 12 hours, and the tundish needs to be replaced with a new tundish to continue production, so that the production cost is increased.
