JPS5978758A - Automatic coiler for quickly cooled metallic wire rod or light-gage strip - Google Patents

Abstract

PURPOSE:To make a coiling roll simple and light and to permit easy follow up to a change in peripheral speed in a device which ejects a molten metal from a nozzle and cools quickly the same to form a wire rod or thin sheet by coating an adhesive mass on the coiling roll and capturing surely the beginning end. CONSTITUTION:A molten material 7 ejected from a curcible 1 is quickly cooled by a cooling roll 2. A wire rod or light-gage strip 8 emitted from the same along a guide 3 is blown by the gaseous flow from a gas ejection port 4 to the adhesive mass 9 on a coiling roll 6 and is quickly coiled by the roll 6. Since the mechanism for capturing the beginning end is extremely simple, lightweight and sure, the follow up to a change in the coiling speed is excellent.

Description

[Detailed Description of the Invention] A molten metal or non-metal material is dropped onto a rotating roll,
The method of forming a filament or ribbon by rapid cooling is currently one of the indispensable methods, especially for the production of amorphous materials.

At this time, since the method of automatically winding the filament or ribbon created from a cooling roll that rotates at a controlled speed is extremely fast, the tension of the created material is limited, so the technology maintains a constant tension or sag. is not easy.

Generally, in the case of small-scale production, the resulting products are scattered randomly, so a separate winding method is used. In addition, in the case of magnetic materials, it is possible to use the adsorption force of a magnet installed on the take-up roll, or to make a number of holes in the take-up roll and use the suction power of the vacuum through these holes to wind the material by suction. There are many possible methods.

Non-magnetic materials cannot be produced using methods that utilize magnetic force,
The method using vacuum has the disadvantage that the adsorption force is insufficient due to the defective shape of the material that initially comes out.This invention was invented to solve the above problem, and it uses magnetic materials, This shows a method for automatically winding VC regardless of non-magnetic material.

To explain this with reference to the figure, the surface tension of the molten material 7v'i put into the crucible 1 is broken by pressure from above, etc.
It is ejected onto the cooling roll 2 which rotates at high speed and is rapidly cooled into a thin ribbon, or it is formed into filaments by digging grooves in the cooling roll 2.

The cooled material is supported by a guide 3 so that it does not fly away due to centrifugal force, and the cooled filament or thin strip 8 is applied to the adhesive by a gas outlet 4 (Fig. 1) or a roll 5 (Fig. 2). The film is automatically wound onto a winding roll 6 coated with 9.

To explain in detail regarding the ribbon 8, the take-up roll 6
When the ribbon 8 and the cooling roll 2 are rotated, the ribbon 8 and the cooling roll 2 are relatively stationary as a matter of course. In this state, the adhesive 9 on the roll surface needs a very small adhesion force to adhere the ribbon 8, such as a gas jet force (Fig. 1) or a light pressing roll 5 (Fig. 2). etc., the winding roll 6 can be harvested. If the ejecting speed of the four bands 8 and the circumferential speed of the cooling roll 20 are significantly different, the adhesive 9 and the thin mB will slip and the adhesion effect will be reduced.

Methods that use vacuum suction force or magnetic force for the take-up roll 6 increase the weight of the roll, but by using the present invention, the roll can be made of a much lighter material such as plastic material. Further, even after the produced ribbon is adhered and wound up, the stress applied to the ribbon can be extremely reduced, and it is extremely advantageous for a mechanism that follows the increase in the diameter of the take-up roll due to winding, that is, the change in circumferential speed.
