Experimental method for performing air cooling and heating process on heating wire rod and air cooling device

Abstract

The invention discloses an experimental method for performing air cooling and heating process on a heating wire rod and an air cooling device. The experimental method adopts the technical scheme that the wire rod is heated to a prescribed temperature by a tubular heating furnace in a laboratory; the wire rod with the prescribed temperature is conveyed out through a heating pipe of the tubular heating furnace; the air cooling device with adjustable wind speed and blast volume is arranged at a delivery outlet of the heating pipe for conveying the wire rod so ensure that the wire rod conveyed bythe heating pipe passes through the air outlet of the air cooling device; thermocouples are inserted in different positions of the wire rod and connected with a digital temperature measuring instrument to reflect the temperature change of the wire rod, and the temperature change signal of the digital temperature measuring instrument is fed back to a variable-frequency controller of the air cooling device so as to control the cooling speed of the wire rod. The invention has the advantages of precisely controllable and adjustable wind speed, blast volume and wire rod cooling speed, as well as simple and compact structure, convenient operation and control, low cost and the like, and can provide the practical and effective experimental data for the enterprise production.

Description

technical field [0001] The invention relates to an experimental method and an air-cooling device for performing air-cooling heat treatment on heated wire rods, belonging to the technical field of air-cooling heat treatment. Background technique [0002] Heat treatment is a powerful measure to improve the mechanical properties of materials, save materials, give full play to the potential of materials, and prolong the service life of machine parts, engineering components and supplies. The heat treatment cooling methods include furnace, air cooling, oil cooling, water cooling and air cooling. However, the air cooling method currently used in the laboratory is limited by itself, and the air volume and speed of the cooling air cannot be accurately controlled according to the needs of the experiment. Therefore, it is difficult to popularize and apply the experimental results to actual production, and it is also difficult to guide the production of enterprises. Since the material ...

AI Technical Summary

Problems solved by technology

In the prior art, the cooling of the wire rod after rolling is mostly air-cooled to obtain the sorbite structure, but there is no ideal air-cooled controlled cooling simulation equipment in the laboratory to study the cooling rate and structure of the wire rod. The relationship between mechanical properties can not provide process improvement schemes and parameters for wire rod production, and can only rely on human experience to guide production

Therefore, the existing experimental method of carrying out air-cooling heat treatment to the heating wire rod is not ideal enough.
