Abstract
The invention discloses a continuous extrusion method. The method comprises the steps that a wheel belt type continuous casting method is firstly adopted, and under the condition that pouring temperature is 680-1,180 DEG C and the rotating linear speed of a casting wheel is 10-50 m/min, molten metal is poured into a square crystallization cavity formed by a casting wheel groove and a steel belt of a wheel belt type continuous casting machine, and a square casting blank with the height of 20-45 mm and the width of 10-35 mm is obtained through continuous casting; and then the square casting blank is directly conveyed into a continuous extrusion machine from the wheel belt type continuous casting machine, and under the condition that the rotating linear speed of an extrusion wheel of the continuous extrusion machine is 10-50 m/min, the square casting blank is continuously extruded into the needed shape. Due to the fact that the wheel belt type continuous casting method is adopted for casting molten metal into the square casting blank and then directly conveying the square casting blank into the continuous extrusion machine for continuous extrusion forming, and continuous casting and continuous extrusion of the square casting blank are integrated and continuous, and therefore production procedures are fewer, the technological process is shorter, and production efficiency is greatly improved.
Description
Technical field
The invention belongs to metal-forming techniques field, specifically relate to a kind of continuous squeezing method.
Background technology
Continual extruding technology is a kind of plastic working new method proposed by the people such as Green in British Atomic Energy Authority's Springfield laboratory in 1972, is described as the revolution of non-ferrous metals processing technology.Compared with conventional extruded method, continual extruding technology has that product grains is tiny, dense structure is high, good mechanical performance, surface quality are good, stock utilization is high, can the advantage such as product of factory length endless, be widely used in non-ferrous metals industry, especially copper, Aluminum-aluminum alloy manufacture field, as copper strap wire, copper bar, copper plate/strip, copper contact wire, cooling aluminum pipe, aluminium transformer belt, aluminum section for automobile etc.
The operation principle of continual extruding technology is pressed in the groove of squeegee roller by blank through pressure wheel, the extrusion chamber be made up of squeegee roller groove and cavity inner surface is continuously fed under the effect of frictional force, blank enters die cavity after cavity material blocking block place retard motion along the circumferential direction, is then squeezed into product by the mould be contained in die cavity.Existing continual extruding technology mainly adopts up-casting oxygen-free copper rod or continuous casting and rolling aluminium bar to be blank, due to blank production with continuously extruded be separate to carry out, and blank needs through coiling, after surface clean, send into continuous extruder again and carry out continuously extruded shaping, make the production process of existing continual extruding technology still more, technological process is still longer.
Summary of the invention
The object of the invention is to for above-mentioned existing problems and deficiency, the continuous squeezing method that a kind of production process is less, technological process is shorter is provided.
Technical scheme of the present invention is achieved in that
Continuous squeezing method of the present invention, be characterized in: first adopt tyre type continuous cast method, pouring temperature be 680 ~ 1180 DEG C, under cast wheel rotational line speed is the condition of 10 ~ 50 ms/min, pouring metal melt is entered in square crystallization cavity that the cast wheel race of round belt continuous casting machine and steel band formed, the cooling spray system arranged by square crystallization cavity surrounding is cooled the molten metal be poured into, and is continuously cast into high 20 ~ 45 millimeters, wide 10 ~ 35 millimeters square strand; Then square strand is communicated directly into continuous extruder from round belt continuous casting machine, under the squeegee roller rotational line speed of continuous extruder is the condition of 10 ~ 50 ms/min, square strand is carried out continuously extruded one-tenth required form.
Operation principle of the present invention is: when in pouring metal melt to the race of the cast wheel of round belt continuous casting machine, under the turning effort of cast wheel, molten metal enters in the square crystallization cavity that formed by cast wheel race and steel band, by the effect of cast wheel surrounding water-spraying control, the crystallization cavity inner metal liquid formed at cast wheel race and steel band is frozen into square strand gradually, and square strand is separated the rear continuous extruder that directly enters and carries out continuously extruded shaping with race.
Compared with prior art, tool has the following advantages in the present invention:
The present invention is owing to being adopt tyre type continuous metal cast process to carry out continuously extruded shaping by directly sending into continuous extruder after molten metal continuous casting squarely strand, achieve the continuous casting of square strand and continuously extruded integrated and serialization, thus production process of the present invention is less, technological process is shorter, drastically increases production efficiency.
