Description

Rapid sample preparation device for blast furnace injection material

Technical Field

The utility model relates to a blast furnace press-in material selective examination technical field specifically is a quick system appearance device of blast furnace press-in material.

Background

The method is characterized in that a material to be pressed is a refractory material, the working temperature of a blast furnace is very high, the local part of the refractory material in the blast furnace needs to be repaired in time when being damaged, the main repair mode at present is to press the fluid refractory material from the outside of the blast furnace, repair the damaged lining after the refractory material is solidified, sample preparation is needed to judge whether the performance of the refractory material is qualified or not, test data is obtained through a series of performance tests to judge whether the performance of the refractory material is qualified or not, the material to be pressed is mainly solidified through natural air drying at present, and the solidification time needs about 72 hours, so that the detection time is prolonged; if the sample is solidified by adopting a high-temperature baking mode, the sample expands to a certain extent due to high temperature, so that the sample overflows a sample preparation mould, and bubbles in the sample are discharged outwards to form surface pits in the heating and baking process, so that the shape and the surface quality of the finally-formed sample do not meet the experimental requirements.

Disclosure of Invention

The utility model aims at providing a blast furnace press-in material rapid sample preparation device, which aims to solve the problem of the rapid sample preparation press-in material adopting the baking mode at present.

The utility model has the following concrete scheme: blast furnace pressure pan feeding system appearance device fast, including the die body, the die body up end is equipped with a plurality of system appearance chamber side by side, and the die body bottom surface is equipped with the bottom plate, and the four corners department that lies in the die body on the bottom plate respectively is equipped with a screw rod, and the screw rod is vertical upwards to extend, and the die body up end is equipped with an apron, and the apron respectively is equipped with a mounting hole to four screw rod departments, is equipped with lock nut on the screw rod and is used for compressing tightly the apron, is equipped with a plurality of exhaust hole to each system appearance chamber department on the apron.

Be equipped with a wire net between apron and the die body up end, the wire net covers all system appearance chambeies, and the aperture of wire net is 1-2mm.

One deck barrier paper is equipped with between wire net and the die body up end.

The utility model discloses removable barrier paper is equipped with in each system appearance intracavity, and the barrier paper prevents that the sample from gluing with system appearance chamber, does benefit to the drawing of patterns.

The mounting hole adopts waist shape hole.

Compared with the prior art, the utility model has the following advantages: the rapid sample preparation is realized, and only 24 hours are needed. Greatly shortens the detection index time and is beneficial to the timely repair construction of the blast furnace.

Detailed Description

Referring to fig. 1-3, this embodiment is a quick system appearance device of blast furnace forced feeding, including die

body

1, 1 up end of die body is equipped with three system appearance chamber 6 side by side, 1 bottom surface symmetry of die body is equipped with two bottom plates 2, the four corners department that lies in die body 1 on the bottom plate 2 respectively is equipped with a

screw rod

3, 3 vertical upwards extensions of screw rod, 1 up end of die body is equipped with an apron 5, apron 5 respectively is equipped with a mounting hole to 3 departments of four screw rods, be equipped with lock nut 4 on the screw rod 3 and be used for compressing tightly apron 5, be equipped with a plurality of exhaust hole 7 to each system appearance chamber department on the apron 5.

In this embodiment, a steel wire mesh is arranged between the cover plate 5 and the upper end surface of the mold body 1, the steel wire mesh covers all the sample making cavities 6, the aperture of the steel wire mesh is 1-2mm, and the aperture of the exhaust hole is reduced when the steel wire mesh is laid, so that a surface pit formed by exhaust in the sample heating process is reduced.

In this embodiment, a layer of isolation paper is arranged between the steel wire mesh and the upper end surface of the die body 1.

In this embodiment, a replaceable isolation paper is arranged in each sample preparation cavity 6, and the isolation paper prevents the sample from being stuck to the sample preparation cavity 6, thereby being beneficial to demoulding.

In this embodiment, the mounting hole is a waist-shaped hole.

The release paper in this embodiment is waste newspaper.

The steps for rapidly preparing the sample by adopting the embodiment are as follows: 1. coating butter or thick machine oil in each sample preparation cavity of the die body and sticking waste newspaper on the inner wall; 2. taking 1.8-2kg of raw materials, dry-mixing for 1-2 minutes, adding 24.5-26.5% of matched bonding agent, adding a proper amount of bonding agent while stirring, and stirring the materials into paste; 3. pouring the pasty sample into a sample preparation cavity, vibrating for 1-2 minutes for forming, and locking the mold after the pug is vibrated to be flat; 4. laying a piece of waste newspaper on the molding surface of the die body, then catching a screen with the aperture of 1mm, then installing a cover plate and tightly pressing the cover plate and the screw rod through a locking nut; 5. directly placing the mixture into a drying oven, baking the mixture for 24 hours at 200 ℃, drying the mixture, cooling the mixture, and then demoulding the mixture to test the related properties of the sample.
