example 1

[0031] For casting high carbon steel, the billet size is 200mm×200mm, the length of the mold is 900mm, the size of the lower mouth of the mold is 201.4mm, the distance between the base line and the upper mouth of the mold is 350mm, and the total taper of the mold outlet section is 0.4% / m, the taper at the exit position is 0, and the total taper above the baseline position is 1.5% / m.

[0032] It can be seen from the above analysis that L=900mm, b=201.4mm, L1=550mm, L2=350mm, T=0.4% / m, T2=0, T'=1.5% / m.

[0033] 1.1 Calculate the side length of the inner cavity of the crystallizer at any position x in the region of the lower mouth of the crystallizer:

[0034] S 1 (x)=201.4+1.4647×10 -6 x 2 ;

[0035] 1.2 Calculate the taper from the base line of the crystallizer to any position x in the area of ​​the lower mouth of the crystallizer:

[0043] Casting alloy steel, the billet size is 600mm×600mm, the length of the mold is 900mm, the size of the lower mouth of the mold is 604.2mm, the distance between the reference line and the upper mouth of the mold is 350mm, and the total taper of the mold outlet section is 0.6% / m , the taper at the exit position is 0, and the total taper above the baseline position is 1.8% / m.

[0044] It can be seen from the above analysis that L=900mm, b=604.2mm, L 1 =550mm, L 2 =350mm, T=0.6% / m, T 2 = 0, T' = 1.8% / m.

[0045] 2.1 Calculate the side length of the inner cavity of the crystallizer at any position x in the region of the lower mouth of the crystallizer:

[0046] S 1 (x)=604.2+6.5913×10 -6 x 2 ;

[0047] 2.2 Calculate the taper from the base line of the crystallizer to any position x in the area of ​​the lower mouth of the crystallizer:

Abstract

The invention relates to the field of steelmaking continuous casting and provides a segmental standard parabola continuous taper obtaining method and device of a crystallizer. The method includes the steps of calculating the crystallizer inner cavity side length at any position in a lower opening area of the crystallizer and the taper of a datum line to any position in the lower opening area of the crystallizer, and calculating the crystallizer inner cavity side length at any position in an upper opening area of the crystallizer and the taper of the position, away from the datum line by any distance, in the upper opening area of the crystallizer. According to the crystallizer manufactured according to the scheme, a blank shell of a casting blank in the crystallizer makes good contact with the wall of the crystallizer at any position, high efficiency of heat transfer between the casting blank and the crystallizer is achieved, and therefore the quality of the casing blank is improved, the casting speed is increased, and significance guarantee is provided for implementation of efficient continuous casting.

Description

technical field [0001] The invention belongs to the field of steelmaking and continuous casting, and in particular relates to a method and a device for obtaining the continuous taper of a segmented reference parabola of a crystallizer. Background technique [0002] The mold is the heart of the continuous casting machine, and the formulation of the mold taper is the core of the mold design process. The rationality of the formulation directly determines the casting speed range that the continuous casting machine can achieve and the quality of the cast slab. If the taper of the mold is set too small, it will easily create an air gap between the billet shell and the mold wall, which will affect the heat transfer between the billet and the mold, resulting in uneven growth of the billet shell in the mold. The inhomogeneity of the billet shell growth process will in turn intensify the air gap between the billet shell and the wall of the mold, which will cause quality problems such ...
