Technical field

This patent belongs to technical field of metallurgical equipment, and in particular to a kind of new copper bismuth liquation hearth furnace bottom chute.

Background technique

Liquate refers to that two kinds of metals can form the metal of eutectic, when its solid melts is at melt slow cooling, in addition to eutectic group At in addition, impurity can form new solid or liquid, separate because of the density of new and old phase difference, be based on state diagram. The smelting of liquate phenomenon crude metal in nonferrous metallurgical process is widely applied, and copper bismuth liquate synthetical recovery is: by cupric bismuth The intermediate materials such as high anode slag, vessel slag, converter oxygen carry out reduction melting and blowing respectively or in mixing investment copper bismuth furnace Obtain Guillaume metal；Copper in Guillaume metal exists in the form of arsenide of metallic copper and copper etc., and copper and bismuth are immiscible in solid-state, But eutectic can be formed, eutectic temperature is 270 DEG C, contains 15% copper in bismuth at this time, this is the theoretical limit of cooling liquation copper removal； Whether the compound of copper or copper, since their fusing point is higher than bismuth, specific gravity is lighter than bismuth, it is possible to be separated by liquate； Guillaume metal is put into copper bismuth liquate reverberatory furnace, heating fusing controls certain temperature, makes copper and its compound in solid-state It is precipitated from bismuth liquid, is pulled out in the form of copper dross slag, and liquid bismuth is in the chute of copper bismuth liquation hearth bottom, because in copper bismuth liquate reverberatory furnace Furnace bottom chute the front is high and the back is low, therefore bismuth can furnace tail by trough outlet collect, to realize the separation of blister copper and thick bismuth.Usually Copper bismuth liquation hearth furnace bottom chute be 20 general steel plate of δ splice welding production because general steel plate make, therefore under high temperature environment its Rigidity, toughness all reduce very much, along with being mounted with heavier Guillaume metal raw material, therefore are easily deformed cracking, are broken, use the longevity Life about 2 months.

Summary of the invention

This patent is intended to provide a kind of at low cost, copper bismuth liquation hearth furnace bottom chute with long service life.

New copper bismuth liquation hearth furnace bottom chute is monoblock cast part, is made of casting technique, material are as follows: Gao Gezhong silicon ball Black cast iron, heat resisting temperature: 1000~1100 DEG C, totality is mounted on copper in cuboid, long 2267mm, wide 1167mm, high 300mm In bismuth liquate reverberatory furnace.

Specific embodiment

A kind of new copper bismuth liquation hearth furnace bottom chute shown in 1~3 with reference to the accompanying drawings, comprising: bottom plate (1), side plate (2) are hung It fills rotating hole (3), bottom gusset (4), chute mouth (5), chute mouth connecting hole (6).

The copper bismuth liquation hearth furnace bottom chute is mounted in copper bismuth liquate reverberatory furnace, and building outside chute has the fire resistings such as refractory brick Material, outermost layer by steel column be fixedly clamped stove entirety.

The bottom plate (1), side plate (2), casting forms entirety, with a thickness of δ 30.

The lifting rotating hole (3) is easy to lift and rotates inclination chute, and reaching chute, the front is high and the back is low, and bismuth can be in furnace tail It is exported and is collected by chute mouth (5), to realize the separation of blister copper and thick bismuth.

The bottom gusset (4), is in " well " font, gusset radius 30mm, rigidity when greatly strengthening chute hot operation, Fracture when high temperature being effectively prevent to carry.

The chute mouth connecting hole (6), connect with furnace outer vent collection device.
