Abstract
A car for carrying large vessels, such as a tundish used in continuous casting, wherein the vessel is raised and lowered while supported on the car, and also can tilt to dump its contents. The car includes a vessel-supporting cradle which tilts from an upright position about an off-center axis located near the bottom and adjacent the side toward which the cradle tilts. Thus the contents of the vessel can be dumped without shifting the car from the position it occupies for teeming metal from a tundish into a mold. Jack screws, which raise and lower the vessel and support the weight, are stressed in tension.
Claims5
In a tundish car which comprises:
- a frame formed of transverse members and low-side and high-side longitudinal members fixed at opposite ends of said transverse members;
- a pair of opposed transverse lift beams adjacent the respective transverse members of said frame;
- and
- means carried by said frame operatively connected with said lift beams for supporting and raising and lowering them,
- the combination therewith of an improved mechanism for supporting a tundish and tilting it to dump its contents, said mechanism comprising:
- a cradle having a pair of end walls and longitudinal means connecting said end walls;
- means pivotally supporting said cradle on said lift beams on an off-center axis nearer said low-side longitudinal member and near the lower edge of the end walls;
- means on said cradle for receiving and supporting a tundish;
- and
- motive means pivoted to aid lift beams near said high-side longitudinal member and to said end walls near the upper edges thereof for tilting said cradle and a tundish carried thereby from an upright position toward said low-side longitudinal member.
In a continuous-casting installation which includes a mold, a tundish car for positioning a tundish over said mold to teem liquid metal into the mold, and a receptacle adjacent said mold into which the contents of the tundish may be dumped, said car comprising:
- a frame formed of transverse members, a low-side longitudinal member on the side adjacent said receptacle, and a high-side longitudinal member on the opposite side, said members being fixidly connected;
- a pair of opposed transverse lift beams adjacent the respective transverse members of said frame;
- and
- means carried by said frame operatively connected with said lift beams for supporting and raising and lowering them;
- the combination with said car of an improved mechanism for supporting a tundish and tilting it to dump its contents into said receptacle, said mechanism comprising:
- a cradle having a pair of end walls and longitudinal means connecting said end walls;
- means pivotally supporting said cradle on said lift beams on an off-center axis nearer said low-side longitudinal member and near the lower edge of said end walls;
- means on said cradle for receiving and supporting a tundish;
- and
- motive means pivoted to said lift beams near said high-side longitudinal member and to said end walls near the upper edges thereof for tilting said cradle and a tundish carried thereby from an upright position toward said receptacle to dump while the car remains in its position for teeming.
