Description
Technical field
The invention belongs to field of metallurgy, relate in particular to the horizontal casting and rolling machine lip of a kind of aluminium and aluminum alloy melt casting.
Background technology
Lip is during aluminium and aluminium alloy casting are produced, before aluminium liquid enters two roll shop building crystallisation by cooling, to make the uniform crucial current supply device of pressure, temperature cross direction profiles of aluminium liquid.At present the type of casting and rolling machine mainly is divided into three kinds of bottom pouring type, horizontal and tiltings.The characteristics such as and the horizontal casting and rolling machine is simple in structure with it, and is easy to operate are adopted by many aluminum fabrication plants.Because the design feature of horizontal casting and rolling machine, its lip inner chamber also generally adopts horizontal structure, and namely the upper and lower surface of lip inner chamber almost is level.Like this in riser and production process, lip inside everywhere flow and the temperature of aluminium liquid often can not evenly distribute, thereby cause the inner phenomenons such as bubble, slagging scorification that produce of lip, and with the passing of production time, bubble and dross can get more and more, have a strong impact on the service life of lip, also caused the strip product defectives such as aberration, slag inclusion, hole often to occur.Therefore, above defective becomes insoluble problem in the industry.
Summary of the invention
Purpose of the present invention namely is to provide a kind of and can overcomes the deficiency that prior art exists, disclose a kind of simple in structure, the measured horizontal casting and rolling machine of the matter of casting lip.
Technical scheme of the present invention is as follows:
This horizontal casting and rolling machine lip, comprise upper plate 1, lower plate 3, base plate 5 and side plate 8, each plate is fixed by iron nail, the rear portion of lip inner chamber has melt inlet 2, the front portion of lip has melt outlet 4, it is characterized in that: the horizontal direction between upper plate 1 and lower plate 2 is intervally distributed with several branching blocks 6, between each branching block 6, leave the spout 7 in liquid flow gap, the inner chamber of described spout 7 is provided with an angle that turns forward in rolling direction, and the shape of lip intracavity liquid chute 7 height increases on rolling direction from front to back gradually.
Above-described some branching blocks are 4～20.
The angle that the inner chamber of the above spout turns forward in rolling direction is 3 °～15 °.
The angle of inclination of the above upper plate is 0 °～5 °; The angle of inclination of described lower plate 3 is 3 °～10 °.
Substantive distinguishing features of the present invention and progress are:
Simple in structure, the casting quality is good.This horizontal casting and rolling machine lip, adopt the inner chamber of spout 7 to be provided with an angle that turns forward in rolling direction, the structure that the shape of lip intracavity liquid chute height increases on rolling direction from front to back gradually, be to be provided with an angle of inclination forward in rolling direction between the composition surface of upper plate and lower plate inner chamber, so can guarantee melt in lip inside with the layer flow mode smooth flow, avoid because the inner chamber sudden changes in elevation causes turbulent flow the bubble in the melt being discharged easily; In addition, the height of spout is front shallow rear dark, and namely lip inner chamber upper and lower surface is inclined upwardly in rolling direction, because Action of Gravity Field can make melt be full of the lip inner chamber, lip inside is difficult for accumulating bubble, guarantees the compactness of strip section bar product tissue; Distribution one row's branching block in lateral separation can make melt flows be evenly distributed in the horizontal between the upper and lower plates of lip inner chamber, guarantees that lip front end melt flow and temperature are even, realizes that the even tissue of strip section bar is fine and close, good product quality.
