Description
Technical field
Sheet billet continuous casting machine production line is flowed the present invention relates to a kind of three machine three, is specially that can match the stream of three machine three of mammoth conveter
Slab caster pours into a mould throwing apparatus for production line, belongs to metallurgical machinery continuous casting throwing equipment technical field.
Background technology
Recently as developing rapidly for China's steel industry, one side production capacity is seriously superfluous, on the other hand new environmental law
It is severe to implement, it is comprehensive to cause iron and steel enterprise's survival pressure aggravation.To reduce cost, converter installation gradually develops to maximization, so
And incident is molten steel equipment for after-treatment scarce capacity problem, the existing conventional maximum section 200 × 1250mm plates of double fluid
Billet continuous casting machine is poured into a mould according to highest pulling rate (2m/min) and produced, and can not also be matched with the quick smelting cycle of mammoth conveter, another
Aspect, slab caster pulling rate is too high, will cause equipment attrition aggravation, the deterioration of strand inside and outside, bleed-out increased risk etc.
Unfavorable factor.Obviously, this big horse matches somebody with somebody the mode of dolly, and the high efficiency for seriously constraining mammoth conveter is played, and causes converter to be poured
Cycle stretch-out is noted, production line final products yield declines.
To match the steel making ability of mammoth conveter, it is a kind of to develop the single current or double-current slab caster of bigger production capacity
Direction, but had using the weak point of this method presence：Brand-new design is needed, implementation needs the long period from manufacturing experimently to shaping
Cycle, and be unfavorable for being transformed using existing sheet billet continuous casting machine equipment to greatest extent；Another method is exactly using existing
Double-current slab caster provisioned in required equipment, exploitation three stream or more runner identical section (or different section) slab
Conticaster, but influenceed by existing double-current slab caster place layout and device structure, can not simply be superimposed one it is (or many
It is individual) runner, main reason is that：Hydraulic vibration unit can not consolidate support, pans it is oversize be easily deformed, can not in two cold houses
Arrangement fan-shaped section driving motor, middle casting stream steam pumping effect can not ensure.With the continuous improvement of metallurgical material technology, in
Between the oversize problem that is easily deformed of tank be progressively resolved, but combine the firm support of hydraulic vibration unit, arrangement sector in two cold houses
Section driving motor, the solution for ensuring the problems such as steam pumping effect is flowed in middle casting, design a kind of stream of three machine three slab caster production
Line, is not seen in document or patent also.
