Abstract
The invention relates to an automatic circulating water descaling system for hot-rolled wire rod steel, and discloses an automatic circulating water descaling system for billet steel. The automatic circulating water descaling system consists of an automatic anti-cleaning water filter, a high-level water tank, a pneumatic injection valve, a plunger pump descaling box and an electronic control cabinet. An operating method for the automatic circulating water descaling system comprises the following steps of: allowing filtered descaling water to enter the high-level water tank; detecting a water level generating signal of the water tank by a magnetic floater liquid level meter, and controlling to close an electric water feed valve; performing flow stabilization on the descaling water, and pressurizing by a plunger pump to enter a collecting pipe of a descaling box; when a hot metal detector detects the temperature of the heat part of the billet steel, sending a signal, and controlling to close the pneumatic injection valve; descaling the descaling water to drop into the descaling box; when the hot metal detector detects the temperature of the tail part of the billet steel, sending a signal, and controlling to open the pneumatic injection valve automatically; and allowing the water in the descaling box to circulate to the high-level water tank. In the automatic circulating water descaling system, due to the arrangement of the pneumatic injection valve, the electric water feed valve, the magnetic floater liquid level meter and the like, the automaticity is improved substantially; and due to the arrangement of a water return pipeline, the descaling water can be recycled, a large amount of water for production is saved, and the production cost of enterprises is reduced.
Description
Technical field
What the present invention announced is a kind of steel billet automatically recycled water descaling system.
Background technology
At present, in the operation of rolling of DEVICE FOR BAR AND WIRE HOT ROLLING steel billet, the water de-scaling equipment of employing is most for pushing the descaling mill or the descaling mill that rolls.The extruding descaling mill is to work in milling train operation way in the steel billet back of coming out of the stove, and the extruding descaling mill carries out mechanical presses to four jiaos of steel billet, makes the oxide skin perk of billet surface, sprays to billet surface with mesolow de-scaling water then, and the oxide skin of perk is removed.The descaling mill that rolls is on roller-way steel billet to be overturn several times, makes the oxide skin of steel surface cracked, sprays billet surface with mesolow de-scaling water again, removes descale.The shortcoming of these two kinds of machineries is complex structures, and technical process is also complicated, and production efficiency is low, and scale removal effect is also bad.At the more residual iron scales of the surface of steel billet meeting, and residual iron scale makes billet surface impression can occur in the mill milling process or is pressed into steel surface, directly influences product quality.In addition, the de-scaling water that existing equipment is used can not recycle, and causes the waste of water resource.Strengthened the production cost of enterprise.
Summary of the invention
At above-mentioned situation, it is good and save the DEVICE FOR BAR AND WIRE HOT ROLLING steel automatically recycled water descaling system of water resource to the purpose of this invention is to provide a kind of scale removal effect.To solve the problem that existing equipment exists.
Structure of the present invention is as shown in drawings: be made of automatic anti-rinse water filter, elevated tank, pneumatic injection valve, plunger displacement pump De-scaling box and electrical control cubicles.One automatic anti-rinse water filter is arranged on supply channel.Outlet side at automatic anti-rinse water filter has an elevated tank.One electronic water-supply valve is arranged on the pipeline between anti-rinse water filter and the elevated tank.One manual butterfly valve is arranged on the water supply line of automatic anti-rinse water filter.On elevated tank, have magnetic float liquidlevel meter.On the outlet pipe of elevated tank bottom, have plunger displacement pump.Be furnished with low-voltage variable-frequency motor and self-lubricating gear pump on the plunger displacement pump.Plunger displacement pump and low-voltage variable-frequency motor, self-lubricating gear pump are formed the plunger displacement pump group.The plunger displacement pump group is three covers.On plunger displacement pump suction line and outlet line, all have valve.In the fuel tank of plunger displacement pump, have the lubricating oil temperature detector, on electrical control cubicles, have the lubricating oil temperature display instrument.On the outlet line terminal of plunger displacement pump, a De-scaling box is arranged.One plunger displacement pump outlet pressure detector is arranged on the outlet line of plunger displacement pump.On electrical control cubicles, have plunger displacement pump outlet pressure display instrument.One thermometal detector above transporting roller-way, steel billet is arranged.Between plunger displacement pump outlet line and elevated tank, have return piping.Have pneumatic injection valve on the return piping.Automatic anti-rinse water filter among the present invention is to be used for filtering the turbid impurity of going back in the water.Magnetic float liquidlevel meter is to be used for showing the cistern water level height and to control electronic water-supply valve switch.Electrical control cubicles among the present invention is arranged in the milling train operating room.Each control circuit of electrical control cubicles is connected with electronic water-supply valve, magnetic float liquidlevel meter, pneumatic injection valve, thermometal detector in the system respectively.De-scaling box is located at the roller-way top.The thermometal detector is positioned at preceding two meters of De-scaling box.Be used for detecting the steel billet temperature, change according to temperature and send signal, control De-scaling box work automatically.The method of work of native system is: de-scaling front opening Hand-operated butterfly valve, de-scaling water enter elevated tank after filtering by automatic anti-rinse water filter.Detect cistern water level by magnetic float liquidlevel meter, look it and just change the generation signal, control electronic water-supply valve and realize opening or closing.De-scaling water is entering the De-scaling box collector by plunger displacement pump under the effect of potential energy after pressurization behind the elevated tank current stabilization.Move to the milling train direction along roller-way after steel billet is come out of the stove, when the thermometal detector measures the steel billet head temperature earlier, send signal, control pneumatic injection valve and close automatically.Simultaneously for the de-scaling water pressure of De-scaling box supply becomes big, produce more through the collector nozzle water of high pressure carries out the de-scaling injection to blank surface in addition through three groups of plunger displacement pumps.Water after the de-scaling falls into De-scaling box.When the thermometal detector measures blank afterbody temperature, send signal, control pneumatic injection valve and open automatically.The water that falls into after the de-scaling in the De-scaling box is recycled to elevated tank.Native system is because have pneumatic injection valve, electronic water-supply valve, magnetic float liquidlevel meter etc., and automaticity increases substantially.In addition, between plunger displacement pump outlet and elevated tank, have water return pipeline, make de-scaling water to recycle, saved a large amount of industrial waters, reduced enterprise's production cost.The present invention, simple in structure, reasonable in design, be a kind of water de-scaling equipment of desirable excellent wire rod steel billet.
