High strenth is able to bear or endure the development that eats compound and fi
From;  Author:Stand originally
This project development studied the mechanism sticking broken bits of lining is mixed mar a reason, put forward to extend the efficient way of lining life, development goes those who suit macrobian life to use a requirement to be able to bear or endure without carbolic high strenth erode Al2O3-SiC simple compound and fireproof stuff; The oxidation problem that explore understands the C in firebrick and porosity tall, aperture is big and bring about material fight broken bits to permeate as bad as aggressivity it is the main reason that lining is marred and sticks broken bits; The small structure design that has stuff next studies with control, development goes have porosity low, aperture small, structure is imperceptible, compact degree tall, be able to bear or endure the high strength do not have carbon with good aggressivity is able to bear or endure erode Al2O3-SiC simple compound and fireproof stuff.
This project basically applies at join and adjusting control puddling and refine
The molten iron between steel is carried, store amortize and pretreatment device, mix iron car namely (torpedo canister) , the high temperature such as canister of the furnace that mix iron, molten iron and taphole channel sets spare fireproof data. Widespread presence fights the fireproof data that uses in the light of afore-mentioned molten iron equipment erode sexual difference, fight broken bits is eroded and the C in material of qualitative lining of osmotic difference, Al2O3-SiC-C oxidizes easily wait for a reason, the later period in often causing lining to be used is marred quickly, life the phenomenon such as broken bits of easy knot of low, equipment, form those who restrict steely production thereby " bottleneck " problem.
Brief technology
This project development studied the mechanism sticking broken bits of lining is mixed mar a reason, put forward to extend the efficient way of lining life, development goes those who suit macrobian life to use a requirement to be able to bear or endure without carbolic high strenth erode Al2O3-SiC simple compound and fireproof stuff, solved " bottleneck " problem. Include tripartite face to study the work:
① confuses iron furnace and the macrobian life issue of the car that mix iron;
The mechanism sticking broken bits of ② lining and mar reason research;
③ is fought without carbolic high strenth erode Al2O3-SiC to pledge compound and fireproof material studies.
On the foundation that mars as thorough as mechanism sticking broken bits research to afore-mentioned fireproof lining, the oxidation problem that explore understands the C in firebrick and porosity tall, aperture is big and bring about material fight broken bits to permeate as bad as aggressivity it is the main reason that lining is marred and sticks broken bits; The small structure design that has stuff next studies with control, development goes have porosity low, aperture small, structure is imperceptible, compact degree tall, be able to bear or endure the high strength do not have carbon with good aggressivity is able to bear or endure erode Al2O3-SiC simple compound and fireproof stuff. Because material does not contain C, intensity is big, stomatic tiny and distributing narrow, material surface sticks broken bits to keep clear of very less, easily, have the good aggressivity that fight broken bits and fight molten iron to erode function, amount of caustic of the frit between operating period is small, durable sex is good. Apply a proof, life of the furnace that mix iron can lengthen 4 times above, 320 tons large life of the car that mix iron lengthens 34% above, solved afore-mentioned " bottleneck " difficult problem.
