Abstract

The utility model provides a core rod preheating furnace. A heat supply pipe for supplying hot air is arranged in a furnace body in the length direction of the preheating furnace, wherein small holes are evenly formed on the pipe wall of the heat supply pipe in the pipe length direction and used for spraying hot air out to heat the core rods. In the direction facing towards the core rod, the small holes are evenly formed on the pipe wall of the heat supply pipe in the pipe length of the heat supply pipe, the hot air is sprayed out from the small holes and then evenly filled in the hearth for heating the core rods, and the core rods are preheated more evenly, therefore, the preheating effect is sufficiently improved.

Description

A kind of plug preheating furnace
Technical field
The utility model relates to the heat supply field of car-type plug preheating furnace, relates in particular to a kind of follow-on plug preheating furnace.
Technical background
The plug preheating furnace is used for the preperforative preheating of plug, and the plug after the preheating is smeared lubricant, utilizes self temperature to come dry lubricant.
At present, before using, plug pines for adopting the flue gas of heating furnace or the hot-air behind the smoke pre-heating in advance, its heat-supplying mode is to send in the burner hearth from lower furnace or top fixing point, because it is big and far away at interval to send into place's flow, make hot-air skewness in stove, thereby make pre-heat effect undesirable.
The utility model content
At shortcoming above-mentioned in the prior art, the utility model provides a kind of plug preheating furnace, furnace superintendent direction along preheating furnace, in body of heater, be provided with the heating tube that is used to supply with hot-air, on the tube wall of described heating tube, evenly be provided with aperture along pipe range, be used to make hot-air from described aperture ejection heating plug.
Further, described heating tube is arranged on the upper furnace of preheating furnace, and described aperture is opened in the bottom of described heating tube.
Plug preheating furnace of the present utility model is because in the direction towards plug, evenly is provided with aperture along the pipe range of heating tube on tube wall, and hot-air can evenly be full of burner hearth after described aperture ejection like this, heats plug, makes that the plug preheating is more even.
Description of drawings
Fig. 1 is the schematic diagram of the utility model plug preheating furnace;
Fig. 2 is the local enlarged diagram of I portion among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing preferred implementation of the present utility model is elaborated.
Shown in seeing figures.1.and.2, be respectively the structural representation and the local enlarged diagram of the utility model plug preheating furnace.By above-mentioned accompanying drawing as can be seen, the structure of plug preheating furnace of the present utility model is specific as follows: along the furnace superintendent direction of preheating furnace, in body of heater, be provided with the heating tube 1 that is used to supply with hot-air, the tube wall upper edge pipe range of heating tube 1 evenly has aperture 2, be used to make hot-air from aperture 2 ejections, evenly be full of burner hearth, the heating plug.This mode can make the plug preheating more even.
Preferably, above-mentioned heating tube 1 is arranged on the upper furnace of preheating furnace, evenly has aperture 2 towards the plug direction along pipe range in heating tube 1 bottom.
Need to prove; the above only is preferred embodiment of the present utility model; rather than to the qualification of technical solutions of the utility model, any the utility model technical characterictic being equal to of being done replaced or corresponding improvement, still within protection domain of the present utility model.
