Description
Technical field
The present invention relates to red copper furnace ingot casting processing technique fields, are specifically related to a kind of red copper furnace cast water pressure stabilizing controlling party
Method.
Background technique
In ingot casting process, cooling velocity refers to the cooling rate of ingot casting, also known as intensity of cooling, in the unit time
The temperature of decline indicates.In actual production, the bad control of this variable, therefore production scene mostly uses cooling water pressure or cold
But measurement of the water flow as cooling velocity.
In direct water-cooling semi-continuous casting, with the increase of intensity of cooling, ingot casting crystallization rate is improved, solute in melt
Element has little time to spread, and degree of supercooling increases, and nucleus increases, thus gained crystal grain is tiny；Meanwhile intermediate zone size reduction, ingot casting
Consistency improves, and reduces loose tendency.Intensity of cooling cross conference cause to be doomed in temperature gradient increase, if being doomed inside
It is unable to synchronous everywhere, then heat stress value also correspondinglys increase, and therefore, ingot crack increases.
In the case where lacking accurate quantification cooling water, largely need cold to judge by the experience of master worker
But the size of intensity causes uncontrollability higher, cast ingot product unstable quality.In order to improve meltshop red copper product at
Product qualification rate reduces uncontrollable factor, designs a set of cast water voltage-stabilization control system, water temperature, flow when to red copper cast and
Pressure has certain regulatory function, to reach the matching relationship of ideal flow and pressure, improves the quality of red copper ingot casting, reduces purple
Copper casting flaw promotes red copper yield rate to promote ingot quality.

To solve technical problem of the invention, used technical solution are as follows:
A kind of red copper furnace cast water pressure stabilizing control method, adds water tank and water pump by red copper furnace apparatus, two is arranged on water tank
A intake tunnel, respectively DN65 tap water pipe line, DN125 water pipe, wherein from scene, water process is turbid follows for DN125 moisturizing
Loop system is normal water supply channel；DN65 pipeline comes from city tap-water, be abnormal condition as having a power failure when to aquaporin and
Water is used in cooling；
Under normal circumstances, the DN125 water pipe from the turbid circulatory system of live water process successively passes through the second worm gear wafer type
Butterfly valve, the first y-type filter and the first Pneumatic butterfly valve enter water tank, then successively passed through by water tank the 5th worm gear wafer type butterfly valve,
First soft connecting tube, water pump, the second soft connecting tube, the 6th worm gear wafer type butterfly valve, the second y-type filter, pressure gauge, stream
Meter and the 4th worm gear wafer type butterfly valve flow to the Fen Shuibao of red copper furnace, supply water to equipment；On the water inlet line of red copper furnace apparatus
By installation distance-transmission pressure gauge and electromagnetic flowmeter, with the pressure and flow of real-time display cast water
Liquid level is reached by level control relay by controlling the second, second opening or closing for Pneumatic butterfly valve after water enters water tank
Control the stable purpose of high water tank；When water tank temperature reaches setting alarming value, feedback automatically turns on running water pipe road
Second Pneumatic butterfly valve is closed the first Pneumatic butterfly valve on turbid circulating water channel, is followed by the supplement of tap water to reduce in water tank
The temperature of ring water；
When abnormal condition such as has a power failure, the city tap-water of DN65 pipeline successively passes through the first worm gear wafer type butterfly valve, the second gas
Dynamic butterfly valve enters in water tank, then from the Fen Shuibao of tank flow red copper furnace, supplies water to equipment；
When water in water pump goes wrong no normal direction equipment supply water tank, from the turbid circulatory system of live water process
DN125 water pipe is connected to by third worm gear wafer type butterfly valve with the second y-type filter, is then supplied water to equipment.
The beneficial effect of the present invention compared with the existing technology is:
The present invention by add buffer tank, variable frequency pump, electromagnetic flowmeter, liquidometer, distance-transmission pressure gauge, electric contact thermometer,
The intelligent measurements such as electromagnetic pneumatic butterfly valve element and pipe fitting, come technological parameters such as the pressure, flow, the temperature that control red copper cast water,
To reach ideal parameter request, the cast quality of ingot casting is promoted, while do not influence other tables uses water.
The present invention increases water tank and water pump near red copper furnace, specializes in and uses to red copper furnace cast water.It can be monitored in system
The parameters such as temperature, pressure and the flow of cast water, while realizing pressure closed loop, variable frequency adjustment makes stable water pressure in the numerical value of setting
On.The cistern water level, cast coolant-temperature gage and water compensating valve switch state of this system devise linkage relationship, guarantee water tank when cast
Liquid level and water temperature.Simultaneously in view of emergency case devises water of meeting an urgent need all the way again, it is contemplated that temporarily used when fault of water pump, it is ensured that
System stable operation.Come requirement when ensuring red copper cast to parameters such as cast coolant-temperature gage, pressure, flows.
Detailed description of the invention
The present invention is made with attached drawing with reference to embodiments and being discussed further.
Fig. 1 is the structural schematic diagram of red copper furnace cast water voltage-stabilization control system.
