Blast furnace should have good performance above all with mud of anhydrous artillery piece (the rate of diameter of deepness of mouth of taphole time, iron, enlarge, pressure that make mashed vegetable or fruit, percent opening, stability) , coordinate the operation before furnace, the direct motion that ability ensures blast furnace is produced and high yield, increase blast furnace to implement macrobian method.
In using a process, mud of anhydrous artillery piece can appear many states, if prepare Chinese medicine by roasting it in a pan mud makes mashed vegetable or fruit hard; Pressure of slimy artillery piece is low, mud of prepare Chinese medicine by roasting it in a panbig gun cannot be pushed send to taphole place; Iron mouth is difficult open; Molten iron dilate is too fast; Iron mouth splash; Taphole time is short; Iron mouth deepness shortens etc;
Operate before blast furnace furnace, affect the use result of mud of anhydrous artillery piece, it is difficult to if appear,make mashed vegetable or fruit, pressure of slimy artillery piece is low, mud of prepare Chinese medicine by roasting it in a panbig gun cannot be pushed send taphole part, these reasons need to operate the careful control of personnel, control the use of quantity of mud of anhydrous artillery piece, examine blast furnace case, treat strictly every time blast furnace taphole, ensure anhydrous prepares Chinese medicine by roasting it in a pan mud is in the use of blast furnace, those who avoid to affect blast furnace is normal move.
A variety of problems that mud of anhydrous artillery piece appears in use process, ensure anhydrous prepares Chinese medicine by roasting it in a pan above all slimy quality, the operation circumstance before needing professional technology personnel to understand the fundamental condition of blast furnace and furnace next, search the account that anhydrous of real impact blast furnace prepares Chinese medicine by roasting it in a pan mud is used, reasonable adjustment, those who will achieve blast furnace is normal move and high yield.
Make mashed vegetable or fruit namely machine of slimy artillery piece chooses mud of anhydrous artillery piece the course that sends taphole, the control that anhydrous prepares Chinese medicine by roasting it in a pan mud makes mashed vegetable or fruit is to turning the operation when sending anhydrous artillery piece mud, how many of the speed of the speed that make mashed vegetable or fruit, quantity that make mashed vegetable or fruit,
Because hit slimy pressure to suffer inside crucible degree of “ flabby ” , and the impact such as hardness of mud of prepare Chinese medicine by roasting it in a panbig gun is bigger, serve as information of crucible job circumstance to feedback to operate personnel to blast furnace only commonly, do not regard the operation that make mashed vegetable or fruit as to control content the pressure that make mashed vegetable or fruit. Can participate in pilot of the operation that make mashed vegetable or fruit to hit slimy process to whether be mixed continuously only the speed that make mashed vegetable or fruit, between content of these two operations, make slimy process only is most simple, and also can be achieved expect the result.
The so-called process that make mashed vegetable or fruit is successive, the halt ” with factitious “ undertakes in whether making slimy process namely, if ” of “ factitious halt undertook in the process that make mashed vegetable or fruit, should hit slimy method to hit slimy ” to also say “ grading hits slimy ” with respect to discontinuous type of the “ that be called so. Investigate through hitting what mud operates for a long time to dog to mouth of blast furnace iron, think “ grading hits slimy ” operation method more commonly used, and be opposite maintain taphole it is deepness, important to safeguard “ mud to wrap ” to be able to rise action.
The “ grading that personnel of the operation before blast furnace furnace uses hits slimy ” method, it is the mud of prepare Chinese medicine by roasting it in a panbig gun that infiltrates 5 multiple of 3 ～ measure volume of iron mouth a narrow passage providing the only means of access to a certain place first, subsequently about removed 1s time infiltrates again a few mud of prepare Chinese medicine by roasting it in a panbig gun, although make mashed vegetable or fruit twice time interval is less, but according to “ mud bag ” forms fundamental analysis, think this operation method basically is correct, should belong to “ discontinuous type to make the category of slimy ” , the effect that its play mud the 2nd times depends on will preparing Chinese medicine by roasting it in a pan mud controls aspect of molten iron fluid the following, to mud the bag has consolidated effect, if improve knowledge further, lengthen the time interval that makes mashed vegetable or fruit twice to 5 ～ 10s, the effect may better, of course this need is explored through preparing Chinese medicine by roasting it in a pan actual and caky time of mud comes affirmatory.
The infiltrates means reachs the capacity that make mashed vegetable or fruit control of mud of anhydrous artillery piece, also having important correlation to the normal direct motion of blast furnace. Mud of anhydrous artillery piece is blast furnace taphole uses fireproof data surely, any operations can affect the smelt of blast furnace.
Slimy bag is the “ child ” that blast furnace anhydrous prepares Chinese medicine by roasting it in a pan slimy action falls, it is blast furnace taphole when jamming, prepare Chinese medicine by roasting it in a pan with mud passageway of machine edge taphole infiltrates the mud of prepare Chinese medicine by roasting it in a panbig gun of blast furnace interior, ” of shape of dawdle of a “ is formed in boiler setting place piece body, adherent it is all round taphole of inside of blast furnace boiler setting, broken bits of iron of the molten iron when be being used at holding back blast furnace taphole is right of boiler setting place erode reach erode, the mud that mud of anhydrous artillery piece forms wraps cent to be primitive mud bag and new student to be wrapped into mud. Primitive mud bag is blast furnace when building furnace, open furnace to be entered by the worker before build load one's writing with fancy phrases of mud of prepare Chinese medicine by roasting it in a panbig gun inside blast furnace, as ore of blast furnace smelt, primitive mud is wrapped by slaggy erode, erode, mud of new anhydrous artillery piece gradually infiltrate, form new slimy package to protect the boiler setting all round blast furnace taphole again.
The mud that mud of anhydrous artillery piece forms wraps in use to need to pass the control that makes mashed vegetable or fruit to form, iron mouth is safeguarded will tell “ twice to hit slimy ” excel one-time make mashed vegetable or fruit, “ hits “ of slimy ” excel 3 times twice to hit slimy ” , its reason still forms a principle to concern with slimy bag, the advantage that combines slimy bag to form a principle to hit slimy ” 3 times to “ has a description, can raise the security of mouth of blast furnace iron and dependability.
When blast furnace taphole is making mashed vegetable or fruit, the slimy bag that infiltrates first time and whole of form ” of “ bear case are forward elapse, the mud of prepare Chinese medicine by roasting it in a panbig gun that makes the 2nd times infiltrate along boiler setting to all around diffuse, meet in the extent that after be caused the effect of density by molten iron, its diffuse downward of course be less than other way apparently, accordingly, reach certain level when the quantity that make mashed vegetable or fruit only, “ mud wraps ” to written guarantee housing reachs particular area, mud of the “ after the pressure that make mashed vegetable or fruit reachs certain level wraps ” ability to be down growth quite, hit mud to measure for the first time must still according to iron mouth a narrow passage providing the only means of access to a certain place the quantitative control of 5 times hits the 3 ～ of actual deepness bulk mud, ten million cannot pass because of iron mouth shallow and dozen mud is overmuch, halt time must lengthen utmost, to “ mud bag ”“ writtens guarantee housing ” and moisture evaporate to perhaps volatilize the portion volatilizes put apart is enough time, with a slow and steady iron to make ” of bag of mud of iron mouth “ firm buccal deepness restores to go up, its hit slimy halt frequency to perhaps say to make slimy number, can increase even 5, but always hit slimy quantity to must be controlled in iron mouth a narrow passage providing the only means of access to a certain place the 8 times less than of actual deepness bulk, dozen mud is overmuch or “ goes up heart of iron mouth ” is cut, often be just the opposite to what one wished. Through control the speed that make mashed vegetable or fruit is mixed the means that make mashed vegetable or fruit, prevent to prepare Chinese medicine by roasting it in a pan slimy “ is hit wear ” , increase make slimy bag form.
The slimy bag that blast furnace anhydrous prepares Chinese medicine by roasting it in a pan mud is formed is having main effect to blast furnace, protect boiler setting not only, still can resist erode slaggily, having main effect to the direct motion of blast furnace.
