Exploitation slag product innovation need be taken all factors into consideration and utilizes the slag quality and recycle the physics heat that hot slag comprised.High added value product innovations such as slag mineral wool have caused the concern and the input of many enterprises.Utilizing slag to prepare mineral wool at present mainly is to utilize the cold conditions slag as main raw material, through after the heating and melting and add other raw materials and carry out mineral wool production again after modified.Though obtaining of cold conditions slag is very easy, it is just passable only need to use truck to access, and still has the opportunity cost of preparation grain slag micro mist.Adopt cupola furnace combustion of coke method that the thawing of cold conditions slag is needed to consume great amount of heat, on the basis that consumes mass energy, also produced CO
2Discharging Deng harmful smoke.
In the process of blast furnace ordinary production, accessing hot slag and prepare mineral wool, is the technological emphasis direction that tackling key problem is studied by current many enterprises.Hot high temperature furnace slag is accessed some amount from normal slag runner need be equipped with corresponding techniques and could realize.General in the past slag all accesses from the dried slag runner afterbody of blast furnace; But, the dried slag runner of blast furnace not only has the switching difficulty between the pit difference of altitude after accessing thermal slag; And could realize that dried slag runner accesses slag after must grain slag thoroughly being dammed; And after switching accesses hot slag, understand the dried slag that continues to produce some amount, thereby the amount of producing of corresponding minimizing grain slag.Be very easy to occur grain slag gas explosion phenomenon in this external dried slag and the grain slag handoff procedure, have certain danger.
In view of this, seek a kind of can be in blast furnace production process the online device that accesses slag at random, become pursuing one's goal of these those skilled in the art to realize blast furnace slag utilization of resources value maximization.
Summary of the invention
The task of the utility model provides the device that the online control at random of a kind of blast furnace stream accesses high-temperature slag; It had both solved the difficult problem that above-mentioned prior art can't access hot slag safely; Realized the target of slag utilization of resources value maximization again; Produce mineral wool product through rationally accessing high-temperature slag; Utilized the heat of hot slag fully, thereby the blast furnace slag that has reduced traditional employing cupola furnace combustion of coke method fusion cold conditions prepares the mass energy that mineral wool consumes, finally obtained the most economical one that slag prepares mineral wool.
The technical solution of the utility model is following:
The online control at random of a kind of blast furnace stream accesses the device of high-temperature slag, comprises refractory materials masonry and baffle plate;
Said masonry is provided with slag runner groove, baffle plate groove and hot slag diffluence pass;
Said slag runner groove is arranged on the centre of masonry longitudinal direction, is straight-through concave shape;
Said baffle plate groove is arranged on the slag runner groove in a lateral direction, and the baffle plate groove bottom land is lower than the height of slag runner groove bottom land, and the two ends of baffle plate groove all are positioned on the cell wall of slag runner groove;
Said hot slag diffluence pass is arranged on the top of a side channel wall of slag runner groove, and is corresponding with baffle plate groove one end port;
Said baffle plate is inserted in the baffle plate groove when accessing hot high temperature furnace slag.
The cell wall top of said hot slag diffluence pass and slag runner groove is that the groove upper edge exists range difference.
The port of said hot slag diffluence pass protrudes in the masonry outer wall.
Adopt the online control at random of blast furnace of the utility model to flow the device that accesses high-temperature slag; Not only realize the safety shunting (size of shunting speed can realize through control liquid level difference) of slag through the liquid level difference of controlling the slag in flowing; And the not iron content slag after the layering is used for preparing mineral wool; And can realize getting at random the requirement of slag through the mode of MC liquid level difference, guarantee that the temperature of the slag of getting is higher and stable.When accessing after slag accomplishes, if with baffle plate just extract out can the security recovery slag grain slag blow process.
The use-pattern of the utility model is that masonry is installed in the position that certain distance is arranged apart from the slag runner afterbody; In baffle plate groove, install baffle plate; The position of adjustment baffle plate lets the baffle plate front and back exist certain height poor, and realization slag slag is controlled stream at random and accessed operation; After treating that slag accesses completion, promote baffle position and let slag recover grain slag blowing operation.
The principal feature that the online control stream at random of the blast furnace of the utility model accesses the device of high-temperature slag is easy, safety, can realize accessing at any time slag, and can control the slag speed of getting, and can guarantee that institute gets in the slag not iron content component simultaneously.The flow that accesses hot high temperature furnace slag can be controlled through the position of inserting baffle plate in the control baffle plate groove; As long as the baffle plate in the baffle plate groove is promoted to the extreme higher position; Slag with regard to full recovery to grain slag blowing operation, when accessing hot slag operation later on once more as long as the above operation of repetition just can realize.
The utility model is to control a kind of security device that stream accesses hot slag in the blast furnace normal productive process at random, and the hot slag of the blast furnace that accesses then can be used to prepare the energy-saving material of fire prevention and insulation.
