TH35212A - Method of continuous casting of metal rods - Google Patents

Abstract

This invention provides a continuous method for casting metal rods. Stable casting without romboid conditions or local deformation. Surrounding side This happens with metal rods that are formed by continuous casting and a mold template is provided for use in such methods. The inner surface is tapered with a stepped reduction. The page is created on the inner surface of the casting template, with small gaps being created. For the part where the frozen cells form and move down Area of each nook, which Consisting of a number of transverse grooves or one, or many deeper sections are assigned It is located under the lowest position of Manicus. Under stable performance conditions It is within 200 mm on the inner surface of the mold template.

Claims (8)

1. The method of continuous casting of metal rods consists in the transfer of molten metal into The upper part of the casting mold is oscillating in the vertical direction. The formwork template is textured by Around the inside of four surfaces With the molten metal in the mold And there is Menicus (Crescent moon shape) with the lowest position The method also includes The arrangement of niches on the four inner surfaces of the template. Each niche area will consist of A number of transverse grooves or a groove The arrangement of such transverse grooves has a minimum average niche depth of 20 microns and a width (W) of them, corresponding to the following formula (1) 3 mm (formula) W (formula ) (Oscillation amplitude of the casting template) x2 + 10 mm ----- (1) Maintaining the lowest point of the menicus of the existing molten metal. In the mold template in During operation in the stability state above the transverse groove and not more than 200 mm above the lower transverse groove, in this way, the cooling capacity of each inner surface of the template is achieved. Such castings are equally uniform. 2. The continuous casting method according to claim 1 also includes Oil supply A small amount of lubrication is applied to the mold. 3. The method of continuous casting of metal rods consists of supplying molten metal into Upper part of the mold template With an oscillation in the vertical direction The formwork template is textured by Around the inside of four surfaces With the molten metal in the mold And there is a Manicus with the lowest position The method also includes The arrangement of niches on the four inner surfaces of the template. Each niche area is composed of many four deeper sections. The arrangement of such a large number of niches has a minimum average niche depth of 20 microns and a diameter (D) of such sections conforming to the following formula (2), which is determined by There is a space between them 3 mm (formula) D (formula) (the oscillation amplitude of the casting template) x2 + 10 mm ------ (2). Maintaining the bottom point of the molten metal menicus contained in such a casting template in During operation in a stable state above many deepest and not more than 200mm above the lowest depth. In this way, the cooling capacity of each inner surface of the template is achieved. Such castings are equally uniform. 4. The continuous casting method according to claim 3 also consists of the distribution of casting oil. Slipped a small amount into the mold. 5. Method of continuous casting of round metal rods consists of pouring molten metal into In the upper part of the casting mold with an oscillation in the vertical direction. Such molded templates have a matte finish. In the rounded place, the aforementioned inner surface of the mold is tapered in such a way that the slit The center of such rounded inner surface is progressively reduced downward. With molten metal in Such mold template And there is a Manicus with the lowest position The method also includes A niche area is provided on the rounded inner surface of the mold, whereby the niche area is composed of a number of transverse grooves or grooves. The arrangement of such transverse grooves has a minimum average niche depth of 20 microns and a width (W) of them, corresponding to the following formula (1) 3 mm (formula) W (formula). (Amplitude, oscillation of the casting template) x2 + 10 mm ------ (1) Maintaining the bottom of the existing molten metal Manicus. In such formwork in During operation in stable conditions above the niche area and not more than 200 mm above the lowest transverse furrow By this way, the cooling capacity of the inner surface of the formwork is achieved. The said uniform. 6. The continuous casting method according to claim 5 also continues with the supply of oil. A small amount of lubrication goes into the mold. 7. The method of continuous casting round metal rod consists of pouring the molten metal into In the upper part of the casting mold with an oscillation in the vertical direction. Such molded templates have a matte finish. In the rounded place, the aforementioned inner surface of the mold is tapered in such a way that the slit The center of such rounded inner surface is progressively reduced downward. With molten metal In the mold template And there is a Manicus with the lowest position The method also includes Providing a niche area on the rounded inner surface of the formwork, the niche area consists of Many deeper parts The arrangement of such a large number of niches with an average niche depth of at least 20 microns and a diameter (D) of them corresponds to the following formula (2), which is determined with a space in between 3. Mm (formula) D (formula) (oscillation amplitude of the casting template) x2 + 10 mm ------- (2) bottom point treatment Manicus' of molten metal is contained in such casting templates in During operation in the state of stability above the niche area And not more than 200 m. Above the part of At the bottom By the way, it will make the capacity In the cooling of each inner surface of the mother Such formwork is equally uniform. 8. The continuous casting method according to claim 7 also includes: Casting oil supply Slipped a small amount into the mold.
