A kind of vertical casting machine of the present utility model has shortened the blocking time with blocking parts, the buffering of molten steel while watering and the bonds well of dummy bar head and initial base shell have been guaranteed to open, reduced blocking operation labour intensity, strengthen dummy bar head blocking in crystallizer and bear the ability that molten steel impacts, prevent from opening the generation of watering bleed-out, the security of raising personnel and equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is blocking plate schematic diagram of the present utility model.
In figure, 1 is dummy bar; 2 is dovetail groove parallels; 3 is crystallizer; 4 is long spring; 5 is blocking plate.
The specific embodiment
Below, according to specification drawings and specific embodiments, a kind of vertical casting machine dummy bar head of the present utility model is further described with blocking plate.
As shown in Figure 1, first by dummy bar (1), adjust the position of dummy bar head in crystallizer; Secondly, use the gap of asbestos cord shutoff between copper plate of crystallizer and dummy bar head; At the inner copper coin of crystallizer (3), contacting position with dummy bar head puts Shop and spreads nail bits; On inclined-plane, dovetail groove both sides, respectively place a parallels (2), then along crystallizer wide direction long spring placed side by side (4); Finally, dummy ingot blocking plate (5) is installed topmost.
A kind of vertical casting machine dummy bar head blocking plate as shown in Figure 2, use material general structure steel, limit portion is used angle bar, and in angle bar, 45 ° of upright footpaths of displacement structure steel of skew back are 5-8mm reinforcing bar, bar spacing 38-42mm, be preferably 40mm, carrying out means of spot welds with angle splice contact, and then on the angle bar having welded and reinforcing bar, another layer of upright footpath of same structure steel 5-8mm reinforcing bar of 90 ° of welding, two-layer reinforcing bar at right angles distributes, and reinforcing bar contact point does not weld.
In whole operation, described nail bits use amount is controlled at 15-20kg, and nail bits piling height is not higher than 3cm; Nail bits use amount is very few, can not play fusing so that the effect of initial base shell and dummy bar head bonding; Nail bits use amount is too much, makes initial base shell and dummy bar head down easily producing and break off relations in motion process, increases the possibility of bleedout.On inclined-plane, dovetail groove both sides, respectively place a parallels, can prevent molten steel impact plug dummy ingot iron filings and asbestos cord etc., preventing that molten steel from getting out from crystallizer bight, causing bleed-out accident.Use dummy ingot blocking plate, reduce on the one hand spring consumption, thereby reduce blocking operation labour intensity, strengthen on the other hand dummy bar head blocking in crystallizer and bear the ability that molten steel impacts, prevent from opening the generation of watering bleed-out, the security of raising personnel and equipment.
