Embodiment Construction

[0010] In order for those skilled in the art to better understand the technical solutions provided by the present invention, the following will be described in conjunction with specific embodiments.

[0011] See figure 1 , which is a structural schematic diagram of a continuous casting system for iron and steel casting in the present invention.

[0012] The continuous casting system for iron and steel casting provided in this embodiment includes a dry-type material tundish 3, a thermal insulation plate tundish 4 and two casting machines 1 and 2, wherein one casting machine 1 pulls the dry-type material tundish 3, and the other The platform casting machine 2 cooperates with the heat insulation plate tundish 4 to arrange equipment maintenance, which not only ensures the completion of the iron elimination task, but also enables the casting machine to carry out planned maintenance in turn; the dry material tundish 3 is made of steel plate material, and the inner On the surface, t...

Abstract

The invention discloses a continuous casting system for iron and steel casting, which comprises a dry material tundish, a thermal insulation plate tundish and two casting machines, one of which pulls the dry material tundish, and the other casting machine is used in conjunction The heat-insulating tundish; the dry tundish is made of steel plate material, and on its inner surface there are reinforcing ribs arranged in the form of evenly distributed ribs; the dry tundish is provided with three Independent roasting system, each roasting system is equipped with an independent gas pipeline, and the three roasting systems adopt the overall purging pipeline system. Compared with the prior art, the continuous casting system for iron and steel casting provided by the present invention, on the one hand, reduces the number of bag changes, speeds up the production rhythm, improves the operation rate of the casting machine, increases the iron elimination capacity, and thus increases the maintenance time of the equipment; On the one hand, it can also reduce head and tail cutting, increase the yield of molten steel, reduce the consumption of steel materials, and create significant economic benefits.

Description

technical field [0001] The invention relates to the field of iron and steel smelting, specifically a continuous casting system for iron and steel casting. Background technique [0002] At present, the daily amount of molten iron in a general medium-scale steelmaking plant is close to 6,000 tons, and the steelmaking production is facing great pressure. If the steelmaking plant adopts two converters, the time for each steel drawing is not more than 8 hours, the replacement of tundish is complicated, the production gap time increases, the operation rate of the casting machine is low, the consumption of steel materials is high, and the backlog of molten iron cannot be arranged. Equipment planned maintenance time. Contents of the invention [0003] In view of the above-mentioned defects, the technical problem solved by the present invention is to provide a continuous casting system for iron and steel casting, on the one hand, it reduces the number of bag changes, speeds up the...
