Abstract
The present invention relates to a kind of techniques with copper scale and production of zinc ingot copper knob semi-finished product, which comprises the following steps: step 1: copper scale is put into heating furnace and is fused into copper water；Step 2: copper water step 2 being stirred with splash bar or fishing slag wooden dipper: zinc ingot metal, heat preservation refining being added into the copper water after step 2, refining temperature is 970~1050 DEG C, refining time 30 minutes, fishes out slag again；Step 4: brass liquid satisfactory in smelting furnace is discharged in the holding furnace below smelting furnace by runner, copper liquid is released after standing 30 minutes in holding furnace and is cast, step 5: the copper bar obtained after being cast by step 4 is put into punching machine, is struck out copper knob blank part using mold；Step 6: by copper knob blank part by measuring truck wheeled litter at copper knob semi-finished product.
Description
Technical field
The present invention relates to copper knob production technologies, and in particular to a kind of work with copper scale and production of zinc ingot copper knob semi-finished product
Skill.
Background technique
Copper knob is corrosion-resistant, and not easy to wear, service life is longer, is widely used in furniture.Existing copper knob processing
Complexity, processing cost is high, and product is easy to loosen, and influences using effect.Therefore, in order to avoid disadvantage existing in the prior art,
It is necessary to make improvement to the prior art.
Summary of the invention
Technical problem to be solved by the present invention lies in view of the above shortcomings of the prior art,
A kind of technique with copper scale and production of zinc ingot copper knob semi-finished product is provided.
To achieve the above object, the present invention provides the following technical scheme that a kind of shaken hands partly with copper scale and production of zinc ingot copper
The technique of finished product, which comprises the following steps:
Step 1: copper scale is put into heating furnace and is fused into copper water；
Step 2: copper water is stirred with splash bar or fishing slag wooden dipper, stirring pulls scum out after stopping；
Step 2: zinc ingot metal, heat preservation refining being added into the copper water after step 2, and refining temperature is 970~1050 DEG C, refining
Time 30 minutes, slag was fished out again；
Step 4: brass liquid satisfactory in smelting furnace is discharged in the holding furnace below smelting furnace by runner, copper liquid
It releases and is cast after standing 30 minutes in holding furnace, guarantee copper water temperature before casting at 1000~1050 DEG C, using graphite
Crystallizer big flow circulating water, 45~50 DEG C of circulating cooling water temperature, circulating cooling water flow 4~5m 4/min, be pulled speed
Spend 3~3.8m/min；
Step 5: the copper bar obtained after being cast by step 4 is put into punching machine, is struck out copper knob blank using mold
Part；
Step 6: by copper knob blank part by measuring truck wheeled litter at copper knob semi-finished product.
A kind of above-mentioned technique with copper scale and production of zinc ingot copper knob semi-finished product can be further arranged to: the step 4
Copper water temperature is at 1020 DEG C before middle casting, and circulating cooling water temperature is at 48 DEG C.
The invention has the benefit that present invention copper scale produces copper and shakes hands, the cost of raw material is saved, state's family property is met
Regeneration policy in source has the good value of environmental protection.
Below with reference to embodiment, invention is further described in detail.
Specific embodiment

Step 2: zinc ingot metal, heat preservation refining being added into the copper water after step 2, and refining temperature is 970~1050 DEG C, refining
Time 30 minutes, slag was fished out again；
Step 4: brass liquid satisfactory in smelting furnace is discharged in the holding furnace below smelting furnace by runner, copper liquid
It releases and is cast after standing 30 minutes in holding furnace, guarantee copper water temperature before casting at 1020 DEG C, using graphite crystallizer
Big flow circulating water, 48 DEG C of circulating cooling water temperature, circulating cooling water flow 4~5m 4/min, 3~3.8m/ of the speed that is pulled
min；
Step 5: the copper bar obtained after being cast by step 4 is put into punching machine, is struck out copper knob blank using mold
Part；
Step 6: by copper knob blank part by measuring truck wheeled litter at copper knob semi-finished product.
