Hot metal drawing

Are you interested in hot drawing of metals, steels and alloys from the supplier company AvecGlob? Here you will find interesting information on this topic

The essence of the process of drawing a metal

Drawing is part of the group of technological processes of the second redistribution of metal, and is used primarily in the metallurgical industry. This is the process of plastic deformation of a continuous material of a volumetric cross-section — a rod, a coil of wire, in which the parent metal passes through a deforming tool — the die, as a result of which its cross section decreases and the length increases.

Hot drawing takes place in the following sequence:

Heating of the semi-finished product to temperatures higher than the temperature of the beginning of recrystallization;

Sharpening the butt of the rod / wire;

Pushing the material into the receiving part of the die;

Capture the end of the workpiece that comes out of the die, with a tick attachment;

Winding of a drawn profile (for a wire), or pulling a workpiece (for a rod).

When drawing, the scheme of the stress-strain state with one tensile-axial-stress acts, in this connection the technological possibilities of the method are limited by the plasticity of the metal. For the intensification of the process, the speed of pulling the wire through the deforming nozzles is reduced.

Urgency of application

Hot drawing is used to produce bars or wires with different cross-sectional dimensions. This is advantageous, for example, in the conditions of mass production, when a reduction in the nomenclature of the initial profiles is achieved. Hot drawing is widely used in metalware production to produce wires of different cross sections from the initial metal roll of the same section, mainly large diameters and from materials with reduced ductility.

Supplier — AvekGlob Company — offers at affordable prices from the manufacturer various metals and alloys that are successfully subjected to hot rolling rolling, in the quantity and assortment that are required by the customer. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Equipment

For the realization of hot drawing, draw drawing mills and drawing drums are used. The former are used for the plastic deformation of rolled products of finite dimensions (rod or circle), the latter for plastic processing of wire. Equipment for hot drawing is distinguished by the following parameters:

According to the maximum dimensions of the cross-section of rolled products;

By the number of simultaneously processed blanks;

By the number of drawing passes, which, depending on the plasticity of the metal, can reach 3… 4;

By drive power;

By the degree of automation of management.

Advantages and limitations

Hot drawing provides:

Significant reduction in the deformation forces of the final profile;

The possibility of more intensive shaping by increasing the number of passes;

Reducing the cost of purchasing a higher nomenclature of rolling profiles.

However, when hot drawing requires the supply of an abundant amount of lubricant, and the durability of the dies (in comparison with cold drawing) is significantly reduced.

Supplier — AvekGlob Company — offers to purchase various metals and alloys processed by hot drawing technology, in any quantity and range of sizes. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
