The utility model can be used for carrying out not only a static test but also a dynamic test for fire-resistant material. The utility model has the advantages of reasonable design, and convenient operation. The rationality and the reliability of test results can be enhanced.
Description
The refractory corrosion trial furnace relates to a kind of pick-up unit that carries out the refractory corrosion performance test.
When carrying out the glass furnace design, rationally selecting fire resistive material for use is a very important job.Kiln design should both make the fire resistive material at each position of kiln body play one's part to the full, and made the fire resistive material basic synchronization at each position of kiln body reach the life-span of kiln again.For carrying out this work, before the kiln design, must carry out the erosion test of fire resistive material, to understand the corrosion-resistant property of various fire resistive materials, accomplish the excellent usefulness of excellent material to glass metal.Concerning fire resistive material manufacturing plant, carry out the refractory corrosion test to the control processing parameter, it is significant to improve the quality of products.
Existing anti-erosion test is to carry out in commercially available molybdenum disilicide lift high temperature furnace.Its burner hearth 1 inwall is equipped with molybdenum disilicide electrical heating elements 2, and furnace roof is closed and is inserted with thermopair 3 in order to detect and the control furnace temperature.Furnace bottom 4 is an integrally-lifting.Insert sample need divide two the step carry out, at first furnace bottom 4 is fallen, the platinum crucible 5 that frit block is housed is inserted, with furnace bottom also to original position.After glass blocks material heat fused becomes liquid, need once more furnace bottom 4 to be fallen, fire resistive material coupon 6 to be inserted in the crucible 5, this step need at high temperature be carried out, and it is very inconvenient to operate.After off-test, the glass metal of adhesion also is difficult at high temperature drip to the greatest extent on the fire resistive material coupon 6, influences result's observation greatly.And in the high temperature furnace of this structure, can't carry out the dynamic erosion test of fire resistive material at all.
The purpose of this utility model is: commercially available molybdenum disilicide high temperature furnace structure is transformed, designed a kind of novel refractory trial furnace, both can carry out the envelope test of fire resistive material with it, can carry out the dynamic test of fire resistive material again.Its loading and unloading sample is more convenient, and the glass metal of adhering on the coupon after the off-test can be most following of hot environment easily, is convenient to result's observation.
The utility model technical solution is: it comprises furnace bottom 4 and the furnace bottom support 7 with integrally-lifting, it is characterized in that: the interior furnace bottom 8 that on furnace bottom 4, is provided with an activity, interior furnace bottom 8 is installed on the main shaft 10 of reducer casing 9, in reducer casing 9 is installed on the lower surface of lifter plate 11 of furnace bottom 8 belows, lifter plate 11 links to each other with elevating mechanism, and interior furnace bottom 8 can carry out elevating movement by the drive of elevating mechanism with lifter plate 11.
The refractory corrosion trial furnace that adopts the utility model scheme to make not only can be done the envelope test of fire resistive material but also can do dynamic test.It is reasonable in design, and is easy to operate, has improved the science and the reliability of test findings greatly, and good economic benefits and social benefit are arranged.
Fig. 1 is the utility model structural representation.
The utility model is described in further detail below in conjunction with accompanying drawing.
Furnace bottom support 7 is made by angle steel, and stent size is 630 * 630 * 800, and outer furnace bottom 4 just is installed on the furnace bottom support 7, and outer furnace bottom 4 is built by laying bricks or stones by fire resistive material and formed, Φ=500.Have the hole of a Φ 200 outside on the furnace bottom 4, the hole is built-in with furnace bottom 8 in, furnace bottom 8 upper base Φ=180 in this, and the Φ that goes to the bottom=200, interior furnace bottom 8 equally also is to be built by laying bricks or stones by fire resistive material to form.Interior furnace bottom 8 is installed on the main shaft 10 of reducer casing 9, and reducer casing 9 is fixed on the lower surface of lifter plate 11.Reducer casing 9 is worm gear, worm speed-down case, by the belt pulley speed change by driven by motor.Carry out dynamic erosion test as need, just can utilize reducer casing 9 to drive interior furnace bottom 8 rotations, platinum crucible 5 rotations in interior furnace bottom 8 can drive again and be placed on the furnace bottom, and, so just can finish the dynamic erosion test of fire resistive material because sample 6 is on the specimen mounting that places on the non-rotary outer furnace bottom 4.
After off-test, when need dripping the glass metal on the sample 6 to the greatest extent, only need interior furnace bottom 8 is fallen, allow sample 6 and glass metal break away from, former furnace bottom 4 is motionless, so just can allow sample 6 continue to remain under the hot environment, and is most until the glass drop of adhering.
Three axle A, B, C are installed on the drift angle of furnace bottom support 7, two sprocket wheels wherein are housed on the A axle, four sprocket wheels are housed on the B axle, five sprocket wheels are housed on the C axle, four drift angles of lifter plate 11 upper surfaces link to each other with four chains, every chain turns to by A, B, the corresponding sprocket wheel of C axle, and the end of four chains links to each other with the lower surface of lifter plate 11.Have four sprocket wheels continuous with four corresponding chains on the C axle, the 5th sprocket wheel that does not link to each other with chain driven by reducer casing 12, owing to five sprocket wheels on the C axle are installed on the same axle, so, but lifter plate 11 is with interior furnace bottom 8 synchronization liftings.Reducer casing 12 be input as hand-crank, the lifting of furnace bottom 8 was easy to operate in the operator can control easily by hand-crank.
