Industrial furnace

Abstract

The invention relates to the field of industrial heating equipment and discloses an industrial furnace. The industrial furnace comprises a furnace body, a heating device and a workpiece bearing device, wherein a hearth is arranged in the furnace body; the heating device and the workpiece bearing device are arranged in the hearth; the workpiece bearing device drives a workpiece to cut isothermal lines on at least one spatial dimension in a temperature field; and / or, the heating device moves in the hearth to form a temperature field which integrally rotates on at least one spatial dimension, so that the isothermal lines in the temperature field are cut by the workpiece. According to the industrial furnace, the workpiece bearing device drives the workpiece or the heating device to move to enable the workpiece to uniformly cut the isothermal lines of the temperature field, so that the workpiece is uniformly heated in a fuzzy temperature region, the heat treatment effect is good, and accordingly, the quality of the workpiece is improved.

Description

Technical field

[0001] The invention relates to the field of industrial heating equipment, in particular to an industrial kiln. Background technique

[0002] In the general industrial heat treatment process, it is necessary to determine the parameters such as the temperature rise curve and the solid-melting time of the alloy parts in order to obtain a uniform mechanical property of the alloy parts. Especially in the crystal growth stage of heat treatment, crystal growth requires a very smooth growth curve. This smooth production curve is difficult to control in an uneven temperature field, and whether the quality of crystal growth depends on this temperature field. Even has a great correlation. In addition, the separation of vanadium-titanium magnetite and the separation of vanadium-titanium also require a stable temperature field.

[0003] In existing industrial heat treatment furnaces, it is difficult to maintain uniform and stable furnace temperature. The uniformity of the hea...
