Abstract
The invention discloses a kind of method of hot state measurement glass melter internal layer pool wall erosion condition, it comprises the steps: under tank furnace melting end is hot, first take down the breastwork above internal layer pool wall and tuckstone; Utilize the height and the thickness that are converted into and need the stainless steel iron staff of angle to measure internal layer pool wall attack sites, thus determine the erosion condition of internal layer pool wall.Adopt method of the present invention, the internal layer pool wall erosion condition under metal line can obtain discovery promptly and accurately and process, avoids the serious accident of running glass metal.
Description
(1) technical field
The present invention relates to a kind of method of hot state measurement glass melter internal layer pool wall erosion condition.
(2) background technology
Glass melter pool wall is built by laying bricks or stones above brick at the bottom of melting end pond, below melting end tuckstone and breastwork.In tank furnace operational process, along with the increase in kiln age, melting end internal layer pool wall is subject to the mechanical erosion in the corrosion of high temp glass liquid and kiln pond, and thickness can be more and more thinner, eats away even completely.Because internal layer pool wall major part is in below metal line, erosion condition is not easily observed, if the internal layer pool wall under metal line corrodes the seriously discovery process that can not get promptly and accurately, can cause the serious accident of running glass metal.
(3) summary of the invention
Can not get the shortcoming promptly and accurately found in order to the internal layer pool wall overcome under existing tank furnace metal line corrodes seriously, the invention provides a kind of method of hot state measurement cell furnace internal layer pool wall erosion condition.
The technical solution used in the present invention is:
A method for hot state measurement glass melter internal layer pool wall erosion condition, comprises the steps:
(1) under tank furnace melting end is hot, takes down the breastwork above the internal layer pool wall need measuring erosion condition, then takes down the tuckstone above internal layer pool wall;
(2) the stainless steel iron staff that is converted into right angle is got; iron staff one end is all the time outside tank furnace; the other end stretches in tank furnace from the breastwork taken down and tuckstone, and the iron staff stretched in tank furnace is close to uppermost internal layer pool wall, measures the distance M1 of the outer iron staff of tank furnace to breastwork;
(3) then iron staff is close to internal layer pool wall, stretches into glass metal from the top down along internal layer pool wall, until run into first slope, take out iron staff, measure the iron staff length H1 being stained with glass metal;
(4) after removing the glass metal adhered to; iron staff is stretched in tank furnace again; be close to internal layer pool wall; glass metal is stretched into from the top down along internal layer pool wall; after running into first slope, maintenance iron staff is parallel with internal layer pool wall to be continued along slope downwards, until slope disappears; stop mobile iron staff, measure the distance M2 of the outer iron staff of tank furnace to breastwork;
(5) then iron staff is taken out in tank furnace, measure the iron staff length H2 being stained with glass metal;
(6) the stainless steel iron staff length difference M2-M1 outside the length difference H2-H1 being stained with glass metal iron staff obtained according to twice measurement, breastwork, determines height and the thickness of internal layer pool wall attack sites, thus determines the erosion condition of internal layer pool wall.
Further, described in stretch into iron staff in kiln length mainly determine according to the height of internal layer pool wall, General Requirements is between 0.1 ~ 2m.
Further, described in stretch into the diameter of iron staff in kiln between 5 ~ 50mm, the too thin insufficient strength of diameter, can be out of shape in the glass metal of high temperature, even fuse, too big and heavy amount is too heavy, operation performance difficulty.
Further, described in stretch into iron staff in kiln, the time at every turn in kiln is not more than 20 minutes, go beyond the scope and be not all suitable for the present invention, this is because pond kiln temperature is at 1400 DEG C to 1600 DEG C, iron staff is long at kiln residence time, can fracture be melted, fall in glass metal.
" until slope disappearance " described in step of the present invention (4) can be understood as two kinds of situations, and one runs at the bottom of pond, and one is not at the bottom of pond, but internal layer pool wall starts to occur and place in 90 ° at the bottom of pond.Beneficial effect of the present invention is: adopt method of the present invention, and the internal layer pool wall erosion condition under metal line can obtain discovery promptly and accurately and process, avoids the serious accident of running glass metal.
Accompanying drawing explanation
Fig. 1 is the tank furnace structural representation that pool wall does not corrode;
Fig. 2 is that pool wall corrodes serious tank furnace structural representation;
Fig. 3, Fig. 4 are tank furnace structural representations when measuring pool wall erosion condition;
Wherein, 1 is internal layer pool wall, and 2 is tuckstone, and 3 is breastwork, and 4 is stainless steel iron staff, and 5 is metal lines.
Embodiment
With reference to Fig. 1, tank furnace melting part structure comprises internal layer pool wall 1, tuckstone 2, breastwork 3, and internal layer pool wall 1 lays tuckstone 2 above, and tuckstone 2 lays breastwork 3 above.When operation is implemented, with reference to Fig. 3, Fig. 4, described measurement tank furnace internal layer pool wall 1 erosion condition step is as follows:
The first step, see Fig. 3, takes down the breastwork 3 above internal layer pool wall 1, then takes down the tuckstone 2 above pool wall under tank furnace melting end is hot;
Second step, see Fig. 3, get the stainless steel iron staff 4 that is converted into right angle, iron staff 4 one end is all the time outside tank furnace, the other end stretches in tank furnace from the breastwork 3 taken down with tuckstone 2, the iron staff 4 stretched in tank furnace is close to uppermost internal layer pool wall 1, measures the distance M1 of the outer iron staff 4 of tank furnace to breastwork 3;
3rd step, see Fig. 3, is then close to internal layer pool wall by iron staff 4, stretches into glass metal from the top down along internal layer pool wall 1, until run into first slope, takes out iron staff 4, measures the iron staff 4 length H1 being stained with glass metal;
4th step; after removing the glass metal adhered to; iron staff 4 is stretched in tank furnace again, see Fig. 4, is close to internal layer pool wall 1; glass metal is stretched into from the top down along internal layer pool wall 1; after running into first slope, maintenance iron staff is parallel with internal layer pool wall to be continued along slope downwards, until slope disappears; stop mobile iron staff 4, measure the distance M2 of the outer iron staff 4 of tank furnace to breastwork 3;
5th step, then takes out iron staff 4 in tank furnace, measures the iron staff 4 length H2 being stained with glass metal;
6th step, the iron staff 4 length difference M1-M2 outside the length difference H2-H1 being stained with glass metal iron staff 4 obtained according to twice measurement, breastwork, determines height and the thickness of internal layer pool wall attack sites, thus determines the erosion condition of internal layer pool wall.
The described iron staff length requirement that to stretch in kiln between 0.1 ~ 2m, diameter at 5 ~ 50mm, described in stretch into iron staff in kiln, the time at every turn in kiln is not more than 20 minutes, otherwise, go beyond the scope and be not all suitable for this technology.
