Description
Technical field
This utility model belongs to fire resisting material field, relates generally to a kind of fireproof material slag resistance sample.
Background technology
Refractory material is the critical material of high-temperature field；Overwhelming majority refractory material at high temperature directly contacts with melt, and slag will directly affect the serviceability of refractory material to the damage degree of refractory material.In actual use, slag is sufficiently complex with the interaction of refractory material, mainly show as slag to the chemical erosion of refractory material, permeate and wash away.And the composition of slag, viscosity and the speed etc. of refractory material relative motion, and the temperature of environment, pressure, atmosphere etc. all produce impact to the resistance to slag of refractory material.
In actual production and commercial Application, and in the scientific research of refractory material, the resistance to slag of refractory material is widely used as the important performance evaluating refractory material；But it is too many owing to affecting the resistance to slag factor of refractory material, the operating mode residing for refractory material that various Thermal Equipments use is different, and the refractory material evaluation result that many specific application environment are used by current refractory material slag resistance test method exists bigger discrepancy with practical using result.And various experimental technique antagonism slag sample and preparation method thereof it is also proposed different requirements.
American Society Testing and Materials proposes rotary slag-resistance test method standard (the ASTM C874-11a Standard of refractory material
Test Method for Rotary Slag Testing of Refractory Materials), it is the sample that 6 groups of fire resistive material products are cut into certain size and shape, be there is the structure of six prism cavitys by the bonding composition of refractory wass one, built by laying bricks or stones in a cylindrical shape furnace shell, with six prism cavitys as burner hearth, the top of six prisms and bottom respectively slag input/air inlet and/gas outlet of slagging tap；Being droped to the ground by burner hearth in level during test, burner hearth rotates with six prism axis for axle, heats burner hearth center with the mixed gas of fuel gas and oxygen for heating source, and process of the test intermittent adds slag and slags tap；By the resistance to slag of the Assessment of Changes refractory material of refractory material sample thickness before and after determination test；The method, with mark shaped brick as original test sample, cuts into certain regular shape by the later stage, then by refractory wass smear bonding by the way of achieve splicing and combining of multiple sample；The advantage of its anti-slag sample is to retain the organizational structure of commercially available prod and former brick face, ensure that " genuine " of tested sample to greatest extent；But, owing to being bonding by refractory wass between sample, rather than natural one, cause the seam of two sample rooms during anti-slag usually to become weak part, cause slag at brickwork joint seepage and be forced termination test；And, the thickness of this anti-slag sample is generally 64mm ~ 65mm, during according to indirect heating manner such as Medium frequency inductions, owing to the penetrance of the thickest electromagnetic field of brick is by a definite limitation.
Going out in China existing national standards GB/T 8,931 2007 refractory material slag resistance test method proposes outside the revolution slagging of retractory method similar with U.S.ASTM standard, also proposed resistance to slag test method Static crucible method commonly used in the research of a kind of refractory material, it is that refractory specimen is made crucible shape, it is placed in burner hearth to loading onto test slag in crucible, allow slag under high temperature react with crucible, with slag, the erosion amount of crucible sample section and infiltration capacity are evaluated the quality of refractory material slag resistance；The preparation of anti-slag sample used by the method is typically cutting drilling mill from bulk sample and produces, or forms to fire after mould compacting balk cargo molding blank or vibrating casting base substrate；This test method emphasizes that the independence between sample individuality is consistent with experimental condition, and its sample is typically made up of a kind of material, it is impossible to realize mutually splicing and combining of many materials.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to propose a kind of fireproof material slag resistance sample.
A kind of fireproof material slag resistance sample, described fireproof material slag resistance sample is the cylindric crucible that lower surface is closed；Described cylindric crucible has reaction zone setting up and down and Sheng Tie district；Distance between described reaction zone and the composition surface in Sheng Tie district and cylindric crucible upper surface is the 1/2 ~ 3/4 of the cylindric crucible interior degree of depth；Described reaction zone is at least one-body molded by the arc block of two pieces of unlike materials；The internal diameter of described cylindric crucible is 100mm～200mm；The side thickness of described cylindric crucible is 10mm～30mm；The base thickness of described cylindrical crucible is 20mm～50mm；Depth of inner cavity is internal diameter 1.2 ~ 2 times of described cylindric crucible.
A kind of fireproof material slag resistance sample that the utility model proposes and preparation method thereof, the reaction zone of fireproof material slag resistance sample is one-body molded by various material, various material can be carried out resistance to slag contrast the most simultaneously；Avoid in test slag from the seepage of storeroom seam, successfully solve many group same stoves of unlike material refractory specimen, simultaneously, the technical problem that contrasts can be carried out with resistance to slag under the conditions of slag, the preparation method of anti-slag sample is simple；Fireproof material slag resistance sample uses cylindric crucible, fireproof material slag resistance sample can preferably ensure that the concordance of control sample experimental condition and environment, improve the persuasion of comparing result；The eddy heating for heating fusing molten iron being disposed to utilize Medium frequency induction to produce in fireproof material slag resistance sample Sheng Tie district, and come heat run slag and refractory crucible sample with these molten iron melted for thermal source by the conduction of heat and radiation, after ferrum and slag all melt, the density due to ferrum is high, the density of slag is low, can make to be formed in crucible molten iron under, slag liquid is in upper molten bath, under the effect of electromagnetic field, molten iron forms eddy current and drives slag liquid Rolling flow；Plane between molten iron and slag liquid is commonly called as " iron wire ", and in this test due to slag liquid and the fluctuation of molten iron, " iron wire " is the most astatic；The slag erosion to Sheng Tie district refractory material during for preventing " iron wire " to reduce, need the refractory material with resistance to slag is arranged in below theoretical iron wire position, and the theoretical iron wire position of design is positioned at the middle part of the crucible degree of depth in this utility model, thus require that the boundary line of Sheng Tie district and reaction zone refractory material is positioned on crucible 1/2 ~ 3/4 along depth of inner cavity.
