1. a kind of holding furnace brass coverture, it is characterised in that: further include potassium chloride, ice crystal including sodium chloride and sodium carbonate One or more of stone, calcium carbonate and magnesium chloride, sodium chloride account for the 30- of holding furnace brass coverture total weight 40%, sodium carbonate accounts for the 30-40% of holding furnace brass coverture total weight.

2. holding furnace according to claim 1 brass coverture, it is characterised in that: when holding furnace brass coverture packet Potassium chloride is included, potassium chloride accounts for the 10-40% of holding furnace brass coverture total weight.

3. holding furnace according to claim 1 brass coverture, it is characterised in that: when holding furnace brass coverture packet Ice crystal is included, ice crystal accounts for 10% or less holding furnace brass coverture total weight.

4. holding furnace according to claim 1 brass coverture, it is characterised in that: when holding furnace brass coverture packet Calcium carbonate is included, calcium carbonate accounts for the 10-20% of holding furnace brass coverture total weight.

5. holding furnace according to claim 1 brass coverture, it is characterised in that: when holding furnace brass coverture packet Magnesium chloride is included, magnesium chloride accounts for 10% or less holding furnace brass coverture total weight.

6. a kind of application method of holding furnace as described in claim 1-5 any claim with brass coverture, feature Be: in turn including the following steps: smelting furnace material, smelting furnace composition adjustment, the degasification of smelting furnace flame, smelting furnace stand, are molten Furnace fishing is grey, smelting furnace undercurrent is transferred to holding furnace, the burnt charcoal of 50~300mm thickness is added in holding furnace, in charcoal Upper covering and heat insulating furnace brass coverture.

[technical field]

The present invention relates to a kind of holding furnace brass covertures and its application method, belong to coverture field.

[background technique]

China is the production and consumption big country of copper products, with being continuously increased for domestic copper products production capacity, the confession of copper raw material Should become restrict internal copper processing enterprise bottleneck, in order to obtain the advantage of market competition, using reclaimed copper production copper products at Drop this measure generallyd use for each enterprise.But in process of production, how energy consumption is further decreased, it is sharp at this to become enterprise The key that can be won in strong competition.

[summary of the invention]

There is provided technical problem to be solved by the present invention lies in overcome the deficiencies in the prior art a kind of cost it is lower, heat preservation Effect better holding furnace brass coverture and its application method.

Above-mentioned technical problem is solved, the present invention adopts the following technical scheme:

A kind of holding furnace brass coverture, including sodium chloride and sodium carbonate, further include potassium chloride, ice crystal, calcium carbonate And one or more of magnesium chloride, sodium chloride account for the 30-40% of holding furnace brass coverture total weight, sodium carbonate accounts for The 30-40% of holding furnace brass coverture total weight.

The invention has the benefit that

By adjusting different types of additive in addition to sodium chloride and sodium carbonate, it is whole with brass coverture to change holding furnace The fusing point of body, holding furnace brass coverture and charcoal contact position are in molten condition since temperature is higher, with air contact Temperature is lower, keeps salt coverture feature.After gap between charcoal is filled up completely and is melted by coverture, since charcoal is put Heat is reduced, and the holding furnace of molten condition, at solid-state, is completely cut off charcoal and air, play good guarantor with brass coverture cooled and solidified Mild isolation air effect prevents metal oxidation, reduces energy consumption.Furthermore sodium chloride, sodium carbonate, potassium chloride, ice crystal, calcium carbonate And magnesium chloride is low in cost, is easy to buy.

The present invention includes potassium chloride when holding furnace brass coverture, and potassium chloride accounts for holding furnace brass coverture total weight 10-40%.

The present invention includes ice crystal when holding furnace brass coverture, and ice crystal accounts for holding furnace brass coverture total weight 10% or less.

The present invention includes calcium carbonate when holding furnace brass coverture, and calcium carbonate accounts for holding furnace brass coverture total weight 10-20%.

The present invention includes magnesium chloride when holding furnace brass coverture, and magnesium chloride accounts for holding furnace brass coverture total weight 10% or less.

A kind of holding furnace application method of brass coverture, in turn includes the following steps: smelting furnace material, smelting furnace at Point adjustment, the degasification of smelting furnace flame, smelting furnace is stood, smelting furnace fishing is grey, smelting furnace undercurrent is transferred to holding furnace, is added in holding furnace The burnt charcoal of 50~300mm thickness, the covering and heat insulating furnace brass coverture on charcoal.

The other features and advantages of the invention will detailed exposure in the following detailed description.

[specific embodiment]
