Description
Technical field
A kind of RH refinings vacuum waste heat groove preheating device is the utility model is related to, belongs to metallurgy industry RH refining equipment technologies
Field.
Background technology
With the further raising to steel cleanliness factor, quality requirement of fast development and client of metallurgical technology, in recent years
Come, in order to improve the internal soundness of molten steel, molten steel vacuum is than improving constantly.RH rectification systems equipment is mainly preheated by four vacuum
Groove forms, and the pre- heat channel of RH vacuum needs first three day in shifting trough to light a fire preheating lance, so that before ensureing use, vacuum preheats
Temperature is higher than 1000 DEG C in groove.
When being preheated to the pre- heat channel of vacuum, during the lower rifle of preheating lance igniting, the easy run-off the straight of fireguard, hinder pre-
The normally lower rifle process of hot rifle, first, causing lower rifle depth inadequate, it is impossible to standby position in arrival slot, second, entering to preheating lance gun body
The a certain degree of damage of row, fireguard damage is will also result in, makes flame excessive, or even cause motor reducer overload to jump electricity,
Under the influence of rifle.
Utility model content
The utility model purpose is to provide a kind of RH refinings vacuum waste heat groove preheating device, can ensure the normal of preheating lance
Lower rifle, solves problem present in background technology.
The technical solution of the utility model is：
A kind of RH refines vacuum waste heat groove preheating device, includes preheating lance, fireguard, the pre- heat channel of vacuum, preheating lid, loudspeaker
Mouth and support bar, the top of the pre- heat channel of vacuum are provided with preheating and covered, and preheating covers the horn mouth for being provided with and being connected with the pre- heat channel of vacuum, institute
It is up big and down small structure to state horn mouth, and horn mouth is provided with two support bars being parallel to each other, is cased with fireguard on preheating lance, in advance
Hot rifle is through horn mouth and extends in the pre- heat channel of vacuum.
The fireguard is cirque structure.
The distance between the diameter of the fireguard and two on horn mouth support bars being parallel to each other are engaged.
The fireguard is welded on preheating lance.
Two support bars being parallel to each other on the horn mouth are arranged symmetrically along bell-mouthed center both sides.
Using the utility model, when being preheated to the pre- heat channel of vacuum, by preheating lance along the horn mouth that preheating covers to true
Lower rifle in empty pre- heat channel, after preheating lance drops to defined depth, the frame that the fireguard on preheating lance can balance is in horn mouth
On two support bars on, avoid run-off the straight, effectively prevent that flame is excessive, ensure effective utilization of heat.
The beneficial effects of the utility model are：It can play a part of protecting RH refining preheating lances and fireguard, can be effective
Avoid the card rifle occurred in preheating lance ignition process, it is ensured that the normal use of RH preheating lances and fireguard, prevent that flame is excessive, protect
Demonstrate,prove effective utilization of heat.
