Abstract
The invention relates to a continuous casting process and a continuous casting machine for an extra-thick plate blank. A continuous casting method and a vertical casting machine are used for producing the extra-thick plate blank, the problem that a casting blank is too thick to be bent and straightened is solved, production flow is shortened, production efficiency is improved and production cost is reduced; and simultaneously, with the vertical casting machine, the casting blank has no bent and straightened deformations, upward flotation of nonmetallic impurities in molten steel is facilitated, and the cleanness of the casting blank is improved; a continuous temperature measuring device and a tundish heating device are both arranged in a tundish, so that a superheat degree of the molten steel in the tundish can be steadily controlled at 10-30 DEG C, and super-cooled or super-heated casting under a condition of low casting speed is avoided; a soft reduction process is executed on a solidified tail end of the casting blank and a dummy bar, so that the problems of center segregation and center porosity in the casting blank are solved; a vertical cutting mode and an oblique pulling ejection mode are used, so that reliable output and feeding of the casting blank and the dummy bar are guaranteed.
Description
Technical field
The present invention relates to the continuous casting process and the conticaster of the above extra-thick plate blank in extra-thick plate blank continuous casting technology field, particularly thickness 400mm.
Background technology
Along with market is also increasing to the demand of slab and special heavy plate, slab and special heavy plate have been widely used in fields such as shipbuilding, pressure vessel, boiler, offshore drilling platform, petroleum and natural gas pipeline, nuclear power station, large bridge, mould at present.At present, produce slab and special heavy plate blank and mainly still adopt die casting method., be raw material basically all for example, adopt the production method of two pyrogene materials, obtain enough compression ratios to guarantee steel plate with the large steel ingot for the steel plate more than the 100mm.When but die casting was produced, owing to adopt steel ingot to cool off naturally, setting time was long, and there are mass defects such as shrinkage cavity, micro-pore, V-type segregation or reverse V-shaped segregation simultaneously in production link many (two pyrogene materials).Therefore the special heavy plate die casting is produced and is existed production efficiency low, and energy consumption is big, and the low and quality of lumber recovery remains problems such as further improvement.
And continuous casting is more suitable for producing special heavy plate from shortening production procedure, the angle of enhancing productivity, save energy and reduce the cost.But traditional continuous casting also is difficult to produce the high-quality super-thick steel plate at present owing to influenced by pourable size restriction and center segregation, micro-pore, middle qualitative factor such as loose.Therefore, how to come production high-quality special heavy plate with the method for continuous casting is the focus of continuous casting worker research always.The large extra thick plate blank of thickness 400～800mm particularly; Because the strand dimensions is big, conventional at present straight arc casting machine does not also possess corresponding bending straightening equipment, adopts straight arc casting machine simultaneously; Straight section short and band liquid chip bending and aligning are difficult to guarantee slab quality.And adopt the vertical bending type casting machine to have the strand bending difficulty after solidifying entirely, be easy to generate surface and internal soundness defective.
Summary of the invention
