Abstract
Provided is a furnace body cooling device for a titanium slag smelting direct-current electric arc furnace. A furnace shell is formed by no less than one cooling module in a combined mode. A cooling water path is arranged in each module and in a winding spiral structure. One end of each cooling water path is connected with a cooling water inlet (1), and the other end of each cooling water path is connected with a cooling water outlet (2). The furnace body cooling device for the titanium slag smelting direct-current electric arc furnace has the advantages of effectively cooling a furnace wall to form a slag adhering layer, and preventing refractory bricks of the furnace wall from being corroded by melt.
Description
Technical field
The utility model belongs to electric arc furnaces shaft cooling field, especially relates to the continuous smelting titanium slag pipeline cooling device of a kind of direct current electric arc furnace.
Background technology
In the electro-smelting of titanium slag, in stove, in the melt pool height scope, must form one deck titanium slag (being commonly called as dross) on the furnace wall, to prevent that the molten titanium slag is to the corrosion of refractory brick.In the unlimited electric furnace batch (-type) of routine was smelted, smelting is interrupted to be carried out, and all will cut off the power supply before every batch the smelting and smash stove, with again feeding temperature-raising melting after in the disposable adding stove of raw material.The titanium slag molten bath that reaction forms enlarges in stove gradually, and unreacted completely furnace charge can stop that the melting titanium slag is to the contact of refractory brick.And in the closed electric furnace continuous smelting, owing to have all the time a certain amount of melting titanium slag in the stove, also do not have the time of outage cooling, so the corrosion risk of furnace wall refractory brick obviously increases than conventional smelting mode.
The utility model content
The purpose of this utility model provides a kind of and can prevent the device that furnace wall refractory brick corrodes by the effective cooling electric stove wall for the deficiency of above-mentioned existence.
The purpose of this utility model is to be achieved through the following technical solutions.
A kind of titanium slag is smelted direct current electric arc furnace shaft cooling device, and the utility model is characterised in that furnace shell is set to be combined by the refrigerating module that is no less than, is provided with cooling water channel in each module, and cooling water channel is set to koji tray shape structure; One end of cooling water channel connects the cooling water inlet, and the other end connects coolant outlet.
The beneficial effects of the utility model are, the furnace wall is divided into a plurality of cooled regions, and each zone is provided with cooling water channel separately.Cooling water enters water channel, takes away to leave behind the heat to enter the circulatory system.Pipeline forces cooling to have very large intensity of cooling, can effectively take away the furnace wall heat, reduces furnace wall temperature, forms stable dross layer in stove.
Below in conjunction with the drawings and specific embodiments the utility model is done further explanation.
Description of drawings
Fig. 1 is the cooling water structure schematic diagram of the single refrigerating module of the utility model;
Fig. 2 is that refrigerating module is arranged side by side the structural representation in the furnace wall.
Among the figure: (1) cooling water inlet, (2) coolant outlet, (3) furnace shell, (4) refractory brick, (5) dross layer.
The specific embodiment
Such as Fig. 1, shown in Figure 2, a kind of titanium slag is smelted direct current electric arc furnace shaft cooling device, the utility model is characterised in that, furnace shell is set to be combined by the refrigerating module that is no less than, is provided with cooling water channel in each module, and cooling water channel is set to koji tray shape structure; One end of cooling water channel connects cooling water inlet 1, and the other end connects coolant outlet 2.
Low-temperature cooling water of the present utility model enters module from entrance 1, absorbing heat leaves and gets back to the circulatory system from exporting 2, and the furnace shell that is cooled off cools off refractory brick again, the temperature of refractory brick is lower than the fusing point of titanium slag, so titanium slag just is set in the stable dross layer of refractory brick surface formation.Cooling water 1 enters the cooling duct from the cooling water inlet, absorbs the refractory material heat, flows back to water system from coolant outlet 2.Cooling water has reduced the temperature of furnace shell and refractory brick, helps the refractory brick surface to form stable solid dross layer, prevents that refractory brick is melted the titanium slag corrosion.
Claims (1)
1. a titanium slag is smelted direct current electric arc furnace shaft cooling device, it is characterized in that furnace shell is set to be combined by the refrigerating module that is no less than, is provided with cooling water channel in each module, and cooling water channel is set to koji tray shape structure; One end of cooling water channel connects cooling water inlet (1), and the other end connects coolant outlet (2).
