Description
Technical field
The utility model relates in copper and Copper fabrication process, the frock used during some high purity copper product meltings, specifically a kind of slag rake for oxygen-free copper melting.
Background technology
As high accuracy oxygen-free copper belt blank, propose very high requirement to material inside organization, electrical property, mechanical performance, the conductance of chemical composition to product of material plays conclusive effect.The first operation that founding operation is produced as oxygen-free copper strip, must ensure the chemical composition of cast article, is very important operation.The pollution of foreign substance to be avoided during Cu-CATH-1 refining, be cast as the ingot casting of low impurity content, thus make its deep processed product have excellent electric conductivity and cycling processability.
Oxygen-free copper melting and refining are being carried out respectively in horizontal type smelting furnace and refining furnace.In melting and refining process, melt and fire resisting material of furnace body at high operating temperatures, can form a certain amount of slag, need, with a kind of instrument, slag is taken off to a place, then take off out.Conventional instrument of skimming in the industry is irony slag rake, contacts in the case of a high temperature with copper liquid, the slag on copper liquid top layer is taken off burner hearth skimming gate, then takes off flake hearth-tapping, by deflector chute, slag is collected slag trapping box and reclaims.This mode of skimming, because Slag Tool is irony, its fusing point is a little more than copper liquid temperature, skimming the incipient stage, also be unlikely to fusing when the temperature of rake is lower, temperature is once raise, and rake is easy to fusing and enters in copper liquid, thus causing melt iron content to increase, ingot chemistry can not meet the demands.This mode of skimming determined due to this body structure of horizontal type smelting furnace, cannot adjust.Therefore need a kind ofly meeting the instrument that can effectively prevent ingot chemistry from not changing under above-mentioned mode prerequisite of skimming.
Summary of the invention
The utility model is solve the technical problem that in horizontal type smelting furnace fusion process, ingot chemistry can change because of the instrument fusing of rake slag, provides a kind of slag rake for oxygen-free copper melting.
The utility model adopts following scheme to realize: a kind of slag rake for oxygen-free copper melting, comprises a handle; Handle front end is connected with a graphite cake by a fixed mount.
Owing to adopting technique scheme, the utility model has following superiority:
When skimming, graphite cake contacts with high-temperature copper liquid, the fusing point of graphite cake is high, and main component charcoal in graphite cake and copper liquid do not react, can not enter into copper liquid causes impurity element to exceed standard, and has certain mechanical strength, is not stained with copper, graphite cake and fixed mount are fixed with bolt, it is convenient to change, and uses this slag rake to skim, ensure that the requirement of oxygen-free copper chemical composition.
Further, the angle of described graphite cake and handle is 90 ~ 120 degree.
Graphite cake and handle are this angle, are beneficial to operation, and leicht fallen D/A.
In process of skimming when the utility model solves oxygen-free copper melting, refining, melt is subject to secondary pollution, the problem that impurity element increases, ensure that the requirement of ingot chemistry micro impurity element, improve conductance and the cycling processability requirement of ingot casting deep processed product.
Accompanying drawing explanation
Fig. 1 the utility model structural representation.
1-handle, 2-fixed mount, 3-graphite cake, 4-bolt.
Detailed description of the invention
For a slag rake for oxygen-free copper melting, comprise a handle 1; Handle 1 front end is connected with a graphite cake 3 by a fixed mount 2.
Described graphite cake 3 is 90 ~ 120 degree with the angle a of handle 1.
Described fixed mount 2 adopts angle steel; Horizontal segment and handle 2 front end of angle steel are welded and fixed, and the vertical section of angle steel is fixedly connected with graphite cake 3 by bolt; The top of graphite cake 3 and angle steel horizontal segment close contact (Fig. 1 can find out), to strengthen the intensity of graphite cake.
1, slag rake is made
Material: steel pipe φ 32 × 3000(is as handle), angle steel 60 × 60, graphite cake 400 × 150 × 20.Angle steel punches with fixing graphite cake, graphite cake 400 × 150 × 20 is holed, and is tightened together by graphite cake, simultaneously by handle and angle steel firm welding with bolt, nut with angle steel.Described graphite cake is the high purity graphite plate made under HTHP.
2, slag operation is taken off
Before using, slightly preheating is done to slag rake graphite cake, can enter burner hearth to skim, graphite cake is close to metal bath surface, and from burner hearth, slag is taken off burner hearth skimming gate by portion, again slag is clawed skimming gate, operating process is noted handling with care, and the senior general's graphite cake that prevents from exerting oneself crashes, and will stop fixed mount in addition and contact with metal liquid, cause metal agglomerates on fixed mount, weight is excessive and cannot use.
The utility model at high temperature has higher mechanical strength, does not burn, chemical reaction does not occur with high-temperature liquid metal, also can not be dissolved in the advantage that molten metal causes impurity element to exceed standard.
Claims (3)
1., for a slag rake for oxygen-free copper melting, comprise a handle (1); It is characterized in that, handle (1) front end is connected with a graphite cake (3) by a fixed mount (2).
2. as claimed in claim 1 for the slag rake of oxygen-free copper melting, it is characterized in that, described graphite cake (3) is 90 ~ 120 degree with the angle of handle (1).
