Embodiment Construction

[0014] A kind of installation method of horizontal continuous casting machine banana seat of the present invention, it comprises:

[0015] a. Banana seat installation and operation essentials:

[0016] After the bottom plate is aligned, use the crane in the workshop to lift the banana seat, or hoist it with two cranes to ensure that the upper support surface of the banana seat is in a horizontal state. The connecting bolts between the banana seats should be tightened initially.

[0017] The upper support surface and the lower inclined support surface of the banana seat should be in good contact with the upper flat bottom plate and the lower inclined bottom plate respectively. If the contact state meets the accuracy requirements, the connecting bolts that penetrate should be tightened symmetrically.

[0018] b. Measurements of the Banana Holder

[0019] Set up a rigid transfer platform to facilitate the erection and detection of the level and theodolite, and use three pairs ...

Abstract

The invention relates to a horizontal continuous casting machine. A mounting method of a banana-shaped seat of a horizontal continuous casting machine comprises the steps of a, banana-shaped seat mounting operation, wherein after a bottom plate is aligned, a crane of a workshop is used for lifting the banana-shaped seat, or two cranes are used for lifting, when the banana-shaped seat is close to the positioning face of a base, a guide rod is inserted for guiding and positioning, and connecting bolts penetrated between the bottom plate and the banana-shaped seat are primarily tightened; b, banana-shaped seat measuring, wherein it is ensured that the whole distorting deviation of the banana-shaped seat is within the allowable range; c, banana-shaped seat adjusting, a gasket set below the bottom plate is used for adjusting the mounting position of the banana-shaped seat until an optical instrument observes that all deviations are within the error allowable range, foundation bolts are symmetrically tightened, meanwhile, the optical instrument is erected for observing, and whether space coordinate position moving of a positioning pin is caused by mis-operation of tightening of the foundation bolts or not is determined. Construction difficulty is effectively reduced, and meanwhile, mounting precision needs are ensured.

Description

technical field [0001] The invention relates to a horizontal continuous casting machine, in particular to a horizontal continuous casting machine banana seat. Background technique [0002] The supporting frame of the sector section of the slab continuous casting machine is commonly called the banana seat, and the banana seat is one of the core equipment of the slab continuous casting machine, which undertakes the dual tasks of supporting and positioning the casting equipment of the sector section and the horizontal section of the tension leveling section and the permanent reference. Their installation restricts the overall online accuracy and rigidity of the entire secondary cooling sector and horizontal casting equipment, as well as the degree of interchangeability of spare parts replacement. [0003] Due to the irregular shape of this part of the equipment and the complex geometric relationship between all the positioning reference pins (surfaces, tables), it is difficult ...
