Mould for working lining of dry material tundish capable of reserving weir plate mounting groove

Abstract

The invention provides a mould for a working lining of a dry material tundish capable of reserving a weir plate mounting groove. The mould comprises a dry material mould and a plurality of groups of groove moulds fitted with the dry material mould; the dry material mould comprises an upper bottom plate, a mould with a side plate and a lower bottom plate integrated with each other, and the lower bottom plate and the upper bottom plate are in the same direction; the length of each groove mould is equal to the vertical height of the dry material mould; each groove mould and the dry material mouldare correspondingly provided with mutually fitted fixing devices used for detachably fixing each groove mould in the vertical direction of the dry material mould; a weir plate mounting groove is formed in the dry material through the groove moulds. The mould for the working lining of the dry material tundish capable of reserving the weir plate mounting groove is convenient to demould, manpower and material resources generated by manual grooving are reduced, and the problems that the shape of a weir plate mounting groove is irregular due to manual grooving, the strength of the surrounding drymaterial is influenced, and a weir plate mounting groove obtained through an embedded part is difficult to position are solved.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a mold for working lining of a dry material tundish which can reserve a weir plate installation groove. Background technique [0002] With the continuous development of steel continuous casting technology, dry-type tundishes have basically replaced traditional smearing materials due to their advantages such as easy construction, long life, and easy turning over, and have been more and more widely used. [0003] The prior art uses dry materials. After the working layer is baked with a mold, in order to install the weir plate, it is generally necessary to manually dig out grooves on the working layer to embed the weir plate, so that the weir plate can be installed more firmly. However, its disadvantage is that due to the high strength of the baked dry material working layer, it is difficult to dig the groove manually, and the shape of the dug groove is irregular, which is easy to af...

AI Technical Summary

Problems solved by technology

However, the disadvantage is that due to the high strength of the baked dry material working layer, it is difficult to dig the groove manually, and the shape of the dug groove is irregular, which is easy to affect the strength of the material around the groove

In the prior art, objects such as wooden strips and foam strips are pre-embedded at the positions where grooves need to be made, but the disadvantage is that the positioning of the embedded parts is difficult, and it is easy to shift during the construction process, resulting in inaccurate positions of the final grooves.
