Abstract
The utility model discloses a steel ladle magnesia carbon brick testing hammer which comprises a hammer body consisting of a hammer handle and a hammer head, wherein the hammer head is of a round ball shape or an elliptical ball shape. The hammer head with the round ball shape or the elliptical ball shape is in a hollow structure; and the hammer handle consists of a metal elastic bar. The steel ladle magnesia carbon brick testing hammer has the advantages that the conventional square hammer head is improved into the round ball-shaped hammer head with the hollow structure, and therefore, the round ball-shaped hammer head are in point contact with the upper surface and the lower surface of each brick body when being used for knocking a magnesia carbon brick, and the knocking sound is clear and bright, thus enabling a testing personnel to easily and accurately judge whether the interior of the brick body has a fracture zone; and the hammer handle consists of the metal elastic bar, thus having a relatively good effect.
Description
Technical field
The utility model relates to refractory brick quality inspection instrument, especially relates to ladle magnesia carbon brick testing hammer.
Background technology
At present, ladle forms by friction press is rolling with magnesia carbon brick is many.Owing to receive to beat the influence that brick weight, pug are done factors such as wet, pug thickness, pug temperature, cause that air row does not come out in the part brick, form sealed porosity slabbing to occur, i.e. the slabbing brick.If these defective brick inspections are not come out and built on ladle, when molten steel corroded the slabbing brick, its rate of decay was than faster, even did not plan a successor, falls layer, and the bag major break down is seriously worn in final appearance.At present the plane set-hammer head of the common wooden hammer handle of the many employings of the detection of slabbing brick is knocked the upper and lower brick face of brick body, judge through the sound that the brick body sends whether brick body inside slabbing occurs.Said method adopts the health check-up of finger tapping brick to test to have improved many than tradition, but also has the omission phenomenon.
Summary of the invention
The utility model purpose is to provide a kind of simple in structure, sound discrimination ladle magnesia carbon brick testing hammer accurately.
For realizing above-mentioned purpose, the utility model is taked following technical proposals:
The described ladle magnesia carbon brick of the utility model testing hammer comprises the hammer body of being made up of hammer handle and tup, and said tup is a spheroidal or oval spherical.
Said spheroidal or oval spherical tup are hollow-core construction; Said hammer handle is made up of metal elastic rods.
The utility model advantage is existing square hammer is improved to the spheroidal tup of hollow-core construction; Like this, when knocking magnesia carbon brick, the spheroidal tup is that point contacts with the above and below of brick body; Knock sent clear bright; Make the reviewer can judge accurately at an easy rate whether brick output body inside exists zone of fracture, and hammer handle is arranged to be made up of metal elastic rods, and its effect is better.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, the described ladle magnesia carbon brick of the utility model testing hammer comprises that said tup 2 is the open circles sphere structure of 20mm for diameter by the length hammer body that to be the hammer handle 1 that constitutes of the metal elastic rods of 300mm forms with tup 2.
Claims (2)
1. a ladle magnesia carbon brick testing hammer comprises the hammer body of being made up of hammer handle (1) and tup (2), it is characterized in that: said tup (2) is spheroidal or oval spherical.
2. ladle magnesia carbon brick testing hammer according to claim 1 is characterized in that: said spheroidal or oval spherical tup (2) are hollow-core construction; Said hammer handle (1) is made up of metal elastic rods.
