Detailed Description
As shown in fig. 1 to 3, an expandable molten steel tank includes a tank body 1, the tank body 1 includes an expandable portion 1a and a main body 1c arranged from top to bottom, a joint part 1b is arranged between the main body 1c and the expansion part 1a, the joint part 1b is integrally formed at the lower part of the expansion part 1a by pressing, the expansion part 1a, the engagement part 1b and the main body 1c are all tapered structures, the engagement part 1b comprises a middle section and a lower engagement section which smoothly engages the middle section with the upper part of the main body 1c, the generating line of interlude is the circular arc of indent, the generating line of linking up the section down is the straight line, and smooth linking sets up the generating line of linking up the section down with the generating line of interlude is tangent and the generating line of linking up the section down links up and parallel arrangement with the generating line of main part 1c, link up the section down with main part 1c welding links to each other. After molten steel loaded by the molten steel tank is lifted through the trunnions 6, the steel shell is reused by static pressure generated by the dead weight of the molten steel, the position of a welding line is changed by additionally arranging the connecting part, as shown in fig. 4, the tensile stress direction of the welding line is parallel to the generatrix of the lower connecting section and the main body, the shear stress of the welding line 7 is reduced, the stress of the welding line is further improved, the welding line is not easy to crack, and the service life of the molten steel tank is effectively prolonged.
The both sides of ladle are connected with respectively and sit jar seat 2, the ladle is located the lower part of sitting jar seat 2 is equipped with the twice and is distributed from top to bottom and around jar lower beaded finish 3 of body 1 setting, the ladle is located the upper portion of sitting jar seat 2 is equipped with strengthens and 4 on one, sit the upper and lower both ends of jar seat 2 respectively with on strengthen with 4 strengthen and fixed connection down, linking portion 1b is located under the twice between beaded finish 3, and beaded finish 3 links to each other through connecting plate 5 under the twice.
