Gas heating and drying box for steel wires

Abstract

The invention relates to a gas heating and drying box for steel wires. The gas heating and drying box comprises a box body, wherein the box body is supported by a stander; a wire inlet branching frame and a wire inlet pressing roller are arranged at one wire inlet end of the box body; a working slot is formed in the box body; a heating device for heating the working slot is arranged in the box body; and a wire outlet supporting roller and a wire outlet branching frame are arranged at one wire outlet end of the box body. The gas heating and drying box is characterized in that the heating device comprises a burner; the burner is arranged on the box body; a fire and smoke channel and a hot air pipeline which is arranged along a length direction of the box body are arranged in the box body; small heat dissipation holes are uniformly formed in two sides of the hot air pipeline; the fire and smoke spraying port of the burner is directly communicated with the inner part of the fire and smoke channel; the outlet of the fire and smoke channel is communicated with the inlet of the hot air pipeline; the hot air pipeline is positioned below the working slot; the working slot is communicated with the hot air pipeline through the small heat dissipation holes; and the working slot is covered by a cover board component. The gas heating and drying box is simple and compact in structure, energy-saving, environment-friendly and easy and convenient to control, and the space can be saved.

Description

technical field [0001] The invention belongs to the technical field of steel wire heat treatment-surface treatment equipment, and in particular relates to a steel wire gas heating drying box. Background technique [0002] In the prior art, in order to improve the comprehensive performance of the steel wire, heat treatment and surface treatment are generally required for the steel wire. Generally speaking, the steel wire has to go through heat treatment, pickling, phosphating, hot water washing, boronization, saponification, drying and other processes during production, and each link has a great influence on the drawing performance of the steel wire. [0003] The steel wire heating and drying box is a common equipment used for drying steel wire in steel wire production. The current steel wire drying box includes a box body, which is equipped with a working channel for heating and drying the steel wire. A heating device for heating the working channel. At present, the heatin...

Problems solved by technology

At present, the heating devices on similar products at home and abroad mainly have two structural forms: electric heating devices and steam heating devices. The utilization rate is low, and the climate temperature is different in winter and summer, and the heating temperature required in the heating and drying box is also different, so the electric heating device will be in an abnormal working state in summer, resulting in a reduction in the service life of the heating device

(2) Using a steam heating device, the heat to maintain the temperature of the heating and drying box mainly comes from the heat release when the high-temperature steam changes from a gaseous state to a liquid state, so the demand for steam is huge and the cost is high, and after the high-temperature steam is converted Discharging the hot water also causes a waste of energy

In addition, the steam heating method needs to be equipped with a boiler to provide a site and related facilities for transporting steam, which occupies a large space and causes waste of raw materials and labor.
