Description
Technical field
The utility model belongs to the device, particularly a kind of device promoting electric furnace continuous casting secondary cooling water intensity of cooling that steel mill continuous casting steel machine improves secondary cooling water intensity of cooling.
Background technology
Steel mill improves requirement because of the conticaster pulling speed of continuous casting supporting with 70 tons of electric furnaces, but the continuous casting secondary cooling water water yield, pressure cannot ensure, and pump house water supply capacity is limited, cannot meet existing production technology demand completely; Need secondary cooling water system boost, augmented flow.
Summary of the invention
The purpose of this utility model is to provide a kind of device promoting electric furnace continuous casting secondary cooling water intensity of cooling, the basis of former water supply capacity can increase water supply pressure and increase output, to meet the intensity of cooling of conticaster secondary cooling water, meet the demand of continuous steel-casting production process.
The purpose of this utility model is achieved in that a kind of device promoting electric furnace continuous casting secondary cooling water intensity of cooling, comprise the secondary cooling water pipeline of feeding secondary cooling water, the arm that secondary cooling water pipeline connects is connected to booster pump by inlet valve, supercharging delivery side of pump is connected to secondary cooling water pipeline by flowing water Valve, connecting entering of booster pump, secondary cooling water pipeline between delivery port arm is installed with stop valve, two arms that secondary cooling water pipeline connects are connected to corresponding filter respectively by inlet valve, the outlet of each filter is connected to secondary cooling water pipeline respectively by flowing water Valve, enter at connection filter, secondary cooling water pipeline between exit branch is installed with stop valve, through pressurization, secondary cooling water after filtration is for conticaster cooling water.
The utility model adds a set of booster pump on original secondary cooling water pipeline, two cover filters in parallel on secondary cooling water pipeline after booster pump, also be connected to corresponding by-pass valve control, improve hydraulic pressure and the flow velocity of secondary cooling water, the resistance decreasing current is damaged, can switch reliably circulating pump and filter, easy access and replacing.
At present the cooling by water system of 70t electric furnace billet caster is transformed, before transformation, square billet secondary cooling water maximum stream flow is bring up to 460L after 280L transformation, the highest pulling rate of square billet brings up to improved 3.2m by transforming front 2.2m, produces steel per year and promotes 100,000 tons, effectively ensure that production capacity.
On the basis of former water supply capacity, the utility model increases water supply pressure and adds output, meets the intensity of cooling of conticaster secondary cooling water, meets the requirement of continuous steel-casting production process.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model will be further described, and Fig. 1 is structural representation of the present utility model.
