Abstract
The utility model relates to a lip used for casting and rolling mill, consisting of a flat box body the front side of which is provided with a melt output split. The utility model is characterized in that the middle of a back plate of the box body is provided with a melt input port, a row of wedge-shaped flow distribution plates are transversally positioned between the upper and lower plates of the box body in width direction. The pointed ends of the flow distribution plates point forward, the clearance between the flow distribution plates is a flow distribution passage the width of which becomes bigger from middle to sides. The utility model can effectively ensure the melt flow evenly in the cavity, present as laminar flow and has no dead space, thereby avoiding sectional blockage, also the temperature at the outlet port of the lip is homogeneous; therefore the consistent crystallization of a plate blank is ensured and the products and alloy products with high quality requirement are produced. At the same time, the utility model has the advantages of a simple structure and convenient processing, thereby being worthy of more value of promotion and application.
Description
Technical field
The utility model relates to the roll casting sheet production field, specifically a kind of casting and rolling machine lip.
Background technology
In roll casting sheet is produced, lip is an important components, be the main carrier of metal the past case input roll gap, the design of lip inner chamber flow dividing structure will directly have influence on made-up belt quality and output, therefore, the lip internal structure all plays critical effect to stablizing casting-rolling technology and improving the quality of products.
Lip structurally should guarantee: streamline reasonable (laminar flow) when melt passes through, no dead band (not having turbulent flow); Melt is evenly distributed on the whole length of roll gap; Melt flows into the temperature of roll gap and also wants uniformity.
As everybody knows, melt enters behind the lip that the lip Way out to the resistance minimum flows under the static pressure effect of preceding case liquid level, boundary layer theory according to equation, lip inside away from the middle section flow velocity on border greater than borderline region, lip is inner basicly stable and flow velocity is consistent for keeping exporting everywhere liquid stream, keep normal casting equilibrium figure, lip inside must be provided with suitable branching block, strengthen fluid resistance at middle section, reduce fluid resistance at borderline region, then resistance control is moderate for both sides of the chest.Therefore, shape, size and the layout of reasonable size, the branching block of runner is very important everywhere in lip inside.
At present, domestic employed lip structure is divided two classes substantially: rectilinear (French 3C) casting and rolling machine with lip and tilting (the casting and rolling machine lip of U.S./FATA-HUNTER), there is following shortcoming respectively in these two kinds of lips:
(1) French 3C formula lip inside is big straight-through runner, fluid resistance is little, flow velocity is big, shunting precision is not high, both sides part fluidity of molten is poor when producing wide plate, especially produce alloy blank (as 5005,5052 etc. and gold), viscosity is big and mobile poor, easily stop up, cause casting to continue;
(2) U.S. FATA-HUNTER formula lip internal shunt passage is little, shunting is even relatively and precision is high, but adopt the rhombus branching block, mouth cavity segment zone can produce turbulent phenomenon, cause non-uniform temperature, make and be unfavorable for grain size inequality after the crystallization producing the demanding product of structure property (as products such as PS slab, aluminium foil blank and deep-draw materials).
Summary of the invention
The purpose of this utility model is to provide a kind of casting and rolling machine lip, this lip shunting precision height, and no dead band not only helps carrying out the continuity production operation, and the product quality height.
The utility model is to constitute like this: a kind of casting and rolling machine lip, the flat box body that is had melt output sealing by the front side constitutes, it is characterized in that: described box body back side panel middle part is provided with melt inlet, between the upper and lower plate of box body broad ways be provided with one row De spaced apart the shape flow distribution plate, described flow distribution plate tip forward, gap between described flow distribution plate is a split channel, and the width of described split channel increases gradually and is symmetrically distributed from the middle part to two sides.
Remarkable advantage of the present utility model is: the design of internal shunt plate is unique, the runner size increases gradually and is symmetrically distributed from the middle part to both sides, so can effectively guarantee melt flows in the mouth chamber evenly, be rendered as laminar flow, no regions of turbulent flow avoids regional area to stop up, and guarantees that simultaneously melt is at lip exit temperature homogeneous, thereby realize slab crystalline structure unanimity, produce the product of high-quality requirement and alloy product (as alloys such as 5005,5052,3105).Simultaneously this practically also has advantages such as simple in structure, easy to process.
Description of drawings
Fig. 1 is a cut-away view of the present utility model.
Fig. 2 is the A-A profile of the utility model Fig. 1.
Among the figure, the 1st, the upper and lower plate of box body; The 2nd, flow distribution plate; The 3rd, the side plate; The 4th, back side panel; The 5th, melt inlet; The 6th, the side swash plate.
The specific embodiment
Below in conjunction with accompanying drawing the utility model being done one describes in detail.
As shown in Figure 1, the utility model relates to a kind of casting and rolling machine lip, the flat box body that is had melt output sealing by the front side constitutes, it is characterized in that: described box body back side panel (4) middle part is provided with melt inlet (5), between the upper and lower plate of box body (1) broad ways be provided with one row De spaced apart shape flow distribution plate (2), described flow distribution plate tip forward, gap between described flow distribution plate (2) is a split channel, and the width of described split channel increases gradually and is symmetrically distributed from the middle part to both sides.
Melt is entered in the lip by the melt inlet (5) of preceding case (liquid reserve tank) on back side panel (4), under certain static pressure melt along back side panel (4) to both sides side plate (3) lateral flow, the split channel of melt through between flow distribution plate (2) longitudinally flows to the lip outlet simultaneously, establish 7 flow distribution plates in the lip altogether, the flow distribution plate at two ends is more smaller than other flow distribution plate on width, the split channel size increases to both sides gradually from the lip middle part, be a＜b among Fig. 1＜c, such layout type makes that the fluid resistance of middle section is bigger, and borderline region is less, allow melt in lip, flow evenly, the flow velocity of each split channel inner fluid is identical, no regions of turbulent flow, and also melt is at lip exit temperature homogeneous, slab crystalline structure unanimity can be guaranteed, the product and the alloy product of high-quality requirement can be produced.
The utility model lip inside dimension is as shown in the table:
Table 1: I take charge of tilting casting and rolling machine lip inside dimension unit: mm
| Casting nozzle plate is wide | 1060 | 1260 |
| The flow distribution plate number | 7 | 7 |
| a | 16 | 19 |
| b | 18 | 22 |
| c | 21 | 27 |
The above only does an explanation to a kind of embodiment of the present utility model, and unrestricted the utility model, and when product width and alloy changed, above-mentioned casting nozzle plate was wide, the gap of flow distribution plate quantity and width, split channel is provided with and all should does corresponding adjustment.
