Abstract
The present invention discloses a making process of an oxygen-measuring copper solution sensor, which comprises the following steps: evenly mixing cobalt powder and cobalt oxide powder according to a certain weight percentage to be put into the lower half part of a ceramic tube; putting alumina powder or the cobalt powder into the upper half part of the ceramic tube; fixing steel wires at the center of the ceramic tube; sealing the open end of the ceramic tube by high temperature resistant glue; making the oxygen-measuring copper solution sensor after being dried. The oxygen-measuring copper solution sensor can be used for exactly measuring the oxygen content of copper liquid in a smelting furnace. Thus, a method that the oxygen content of the copper liquid is estimated by operators' experience in old days is changed; a problem that the oxygen content of the copper liquid in a smelting process can not be exactly controlled in a smelting copper process because of estimated errors is avoided. Thus, the quality of smelted copper products is greatly improved.
Description
Technical field
The present invention relates to metallurgy industry surveying instrument technical field, particularly copper smelting liquid is decided the lambda sensor method for making.
Background technology
Its application places difference of copper material that oxygen content is different, for example the oxygen-free copper cable is widely used in karaoke machine.Copper material can be controlled the oxygen content of copper liquid by smelting process in smelting process, but only under the prerequisite of oxygen content, could control the copper material that smelting process is produced different oxygen level effectively in measuring copper liquid exactly.At present, oxygen content is just with the experience estimation of experienced technician in smelting process in the measurement copper liquid, the instrument that does not also have oxygen content in a kind of accurate measurement copper liquid, error appears in this experience estimation unavoidably, this error causes smelting the copper material that and does not meet needed oxygen level requirement, thereby causes underproof copper material to overstock and waste.
Summary of the invention
The purpose of this invention is to provide a kind of copper liquid and decide lambda sensor analyzer method for making, this sensor can accurately measure the oxygen content in the copper liquid in the smelting furnace, thereby according to the demand different to the copper material oxygen level, smelts the copper material of different oxygen level.
For achieving the above object, the technical solution adopted in the present invention is: a kind of copper liquid is decided the lambda sensor method for making, and its processing step is:
Cobalt powder and cobalt oxide powder are (70%-90%) by weight percentage: ratio (10%-30%) is put into nonmetallic vessel and is mixed, and grinds then more than half an hour;
With an end sharpening of iron wire, curving 90 ° of straight hooks apart from most advanced and sophisticated 2 millimeters places, the end with buckle inserts a bottom portion that shuts in the ceramic pipe again, and the other end of iron wire is exposed at the top of ceramic pipe opening one end;
Pour into good cobalt powder of barreling and cobalt oxide powder mixed-powder in ceramic pipe, Bu Duan Dun is real, makes mixed-powder account for the 10%-90% of ceramic pipe volume, and makes iron wire be positioned at the centre of ceramic pipe;
The first half at ceramic pipe pours into alumina powder or cobalt powder, and Bu Duan Dun is real, till filling ceramic pipe;
With the high temperature resistant ceramic pipe openend of sealing, air dry is more than 24 hours;
Packaged ceramic pipe was toasted in baking oven more than 16 hours, and oven temperature remains on 60 ℃ ± 5 ℃.
The purity of described cobalt powder and cobalt oxide powder is more than 99%.
Described ceramic pipe adopts the cobalt oxide pipe.
The copper liquid that adopts technique scheme to produce is decided lambda sensor in use, be connected with the oxygen content display by lead being exposed at outer iron wire one end of ceramic pipe, then this analyzer is put into copper liquid to be measured, because ceramic pipe has air permeability and good, oxygen in copper liquid just may penetrate in the ceramic pipe, with the material generation chemical reaction in the pipe, oxygen content difference in the copper liquid, its chemical reaction is also different, and be transported in the oxygen content display with different voltage signals, by conversion, voltage signal is converted to the oxygen content value, so can measure the oxygen content in the copper liquid exactly.
The principle of work of deciding lambda sensor from the invention described above copper liquid as can be seen, the present invention has significant beneficial effect, adopt this sensor can measure the oxygen content of copper liquid in the smelting furnace exactly, smelt the copper material of different oxygen level according to demand, solved the problem that causes the smelting quality difference by oxygen level in the experience estimation copper liquid.
