Description
Technical field
The utility model relates to a kind of blast furnace mud sample, relates in particular to a kind of stemming slag corrosion resistance sample mould.
Background technology
Stemming is the refractory material that blast furnace is used for botting, and can the quality of its performance is directly connected to blast furnace safe operation.Along with blast furnace maximizes, the development of longevityization, performance requirement to stemming is also more and more higher, being embodied in the operation, volume stability, agglutinating property and the opening performance that not only require stemming will get well, have simultaneously that stronger anti-slag, anti-molten iron corrode and anti-ly wash away, anti-oxidation characteristics.
Stemming conventional detection project comprises indexs such as horse summer value, compressive resistance, rupture strength, bulk density, chemical composition at present, consider that stemming is washed away by molten iron, slag action in use, require it to have good anti-slag iron erosion performance, so in the stemming test item, introduce anti-slag iron erosion performance index, adopt the static sample in the anti-slag iron of the blast furnace fireproof material erosion test method to soak the slag venting method, be used for the anti-slag iron of quantitative assessment stemming erosion performance.
In stemming slag corrosion resistance specimen test, sample is made the cylinder of hollow on request, and its cross section is an annular, and hollow space is made of the cylinder of two sections different-diameters up and down, use traditional forming method can't successfully make sample, therefore press for a kind of mould of design.
The utility model content
The purpose of this utility model is to design a kind of particular manufacturing craft, can suppress stemming slag corrosion resistance sample easily.
The technical solution of the utility model is achieved in that stemming slag corrosion resistance sample mould, is made up of external mold, base, pressure exemplar, profiled member, and external mold is a tubular cylinder; First cylinder that base is reduced successively by common center line, diameter, second cylinder, three cylindrical body, the stack of the 4th cylinder constitute, base inserts the external mold cavity, first cylinder and external mold inwall closely cooperate, base end face is concordant with the external mold bottom surface, and second cylinder, three cylindrical body, the 4th cylindrical diameter are corresponding with two sections different inner diameters of the external diameter of stemming slag corrosion resistance sample and cavity respectively; The pressure exemplar is a tubular cylinder, presses exemplar cavity and base the 4th cylinder to closely cooperate; Profiled member is a tubular cylinder, and profiled member tube wall bottom is stuck between external mold inwall and the base second cylinder external diameter, and profiled member external diameter and external mold internal diameter closely cooperate, and profiled member internal diameter and base second cylinder closely cooperate.
Preferably, described pressure exemplar outer wall has the bank ear, to locate the distance of pressing exemplar to depress.
Preferably, described profiled member is made up of two semicircle pipes.
Preferably, described external mold inwall, profiled member outer wall have the gradient of corresponding 2-3%.
Use the utility model can suppress standard stemming slag corrosion resistance sample, the sample corner angle that suppress are clearly demarcated, and centre bore is complete; Press the bank ear of exemplar outer wall that the distance of pressing exemplar to depress is located fast; Profiled member is a split type structure, and external mold inwall, profiled member outer wall have corresponding gradient to make sample be convenient to the demoulding; And the utility model is simple to operate, and mould easily maintains, and is easy to assembly.
Description of drawings
Accompanying drawing 1 is a stemming slag corrosion resistance sample structure schematic diagram.
Accompanying drawing 2 is the utility model structural representations.
Among the figure, the 1-external mold; The 2-base; 2-1-first cylinder; 2-2-second cylinder; 2-3-three cylindrical body;
2-4-the 4th cylinder; 3-presses exemplar; The 4-profiled member; 5-bank ear.
The specific embodiment
Be further described below in conjunction with accompanying drawing:
As shown in the figure, stemming slag corrosion resistance sample mould is made up of external mold 1, base 2, pressure exemplar 3, profiled member 4, and external mold 1 is a tubular cylinder; The first cylinder 2-1 that base is reduced successively by common center line, diameter, the second cylinder 2-2, three cylindrical body 2-3, the 4th cylinder 2-4 stack constitute, base 2 inserts external mold 1 cavity, the first cylinder 2-1 and external mold inwall closely cooperate, base end face is concordant with the external mold bottom surface, and the diameter of the second cylinder 2-2, three cylindrical body 2-3, the 4th cylinder 2-4 is corresponding with two sections different inner diameters of the external diameter of stemming slag corrosion resistance sample and cavity respectively; Pressing exemplar 3 is tubular cylinder, presses exemplar 3 cavitys and base the 4th cylinder 2-4 to closely cooperate, and presses the exemplar outer wall that bank ear 5 is arranged; Profiled member 4 is a tubular cylinder, form by two semicircle pipes, profiled member 4 tube walls bottom is stuck between external mold 1 inwall and the base second cylinder 2-2 external diameter, and profiled member 4 external diameters and external mold 1 internal diameter closely cooperate, and profiled member 4 internal diameters and the base second cylinder 2-2 closely cooperate; Described external mold 1 inwall, profiled member 4 outer walls have the gradient of corresponding 2-3%, are convenient to the sample demoulding.
1 containing of external mold, fixation firmly are assembled together base 2 and pressure exemplar 3 on request; Base 2 is the effect that base also has out centre bore; Press exemplar 3 to be responsible for pressing samples, the also effect that ejects from external mold 1 of handlebar base 2 and profiled member 4 after having pressed; Profiled member 4 is made up of two identical semicircle pipes, plays moulding and demoulding effect.
When using this Mold Making stemming slag corrosion resistance sample, need to coat lubricating oil at the inner surface of external mold 1, the outer surface of base 2, the outer surface of pressure exemplar 3 and the surfaces externally and internally of profiled member 4 earlier, with conveniently stripped.Assemble mould according to installation diagram during sample preparation, to press exemplar 3 to take off earlier, taking by weighing a certain amount of stemming packs in the mould, with instrument stemming is tamped, to press exemplar 3 to load onto then, and entire die will be placed on the forcing press suppress, when the bank ear 5 of pressing exemplar 3 middle parts touches profiled member 4, compacting is finished, and mould is taken off from forcing press carry out the demoulding.
During the demoulding, will press exemplar 3 to take off earlier, be placed on base 2 below, firmly just base 2 and profiled member 4 can be ejected from external mold 1, after base 2 and profiled member 4 were ejected, slowly rotating base 2 produced it from profiled member 4, then profiled member 4 is carefully separated stemming slag corrosion resistance sample demoulding success.After each sample preparation is intact with all parts wiped clean of mould and coat lubricating oil and treat to use next time.
By facts have proved in a large number, use this mould can not only successfully suppress stemming slag corrosion resistance sample, and the sample edge of compacting is intact clear, centre bore is complete, and sample preparation is effective.This mould also is suitable for the anti-iron of compacting stemming and corrodes sample, and forming method is consistent with said method.
