Abstract
ABSTRACT OF THE DISCLOSURE:
The present invention provides as electrode for oxygen-arc cutting which is unlikely to peel and which is not liable to produce gas or smoke which is likely to affect the health of an operator using it. The present invention provides an electrode for oxygen-arc cutting comprising: an electrically conducting body of a desired length; at least one oxygen passage formed within and along the electrically conducting body, and an outer layer formed on the outer periphery of the electrically conducting body, said outer layer being paper layer which is impregnated with a silicate material such as sodium silicate.
The present invention provides as electrode for oxygen-arc cutting which is unlikely to peel and which is not liable to produce gas or smoke which is likely to affect the health of an operator using it. The present invention provides an electrode for oxygen-arc cutting comprising: an electrically conducting body of a desired length; at least one oxygen passage formed within and along the electrically conducting body, and an outer layer formed on the outer periphery of the electrically conducting body, said outer layer being paper layer which is impregnated with a silicate material such as sodium silicate.
Description
1()7892~
This invention reIates to electrodes for oxygen-arc cutting.
Conventional electrodes for oxygen-arc cutting have a coating layer of flux enclosing the outer periphery of the metal tube or electrically-conducting tubular body.
Therefore, when the electrodes are subjected to stresses or mois-ture, the flux is liable to peel off so that the desired cutting operation cannot be conducted and furthermore, a gas of an offensive odour is given off from the coating layer by the arc -heat and can adversely affect the health of operators.
The present invention provides an-electrode for oxygen-arc cutting which is unlikely to peel even in the adverse working conditions mentioned above and which is not liable to produce gas or smoke which is likely to affect the health of an operator using it.
The present invention provides an electrode for oxygen-arc cutting comprising:
i~ an electrically conducting body of a desired length ii) at least one oxygen passage formed within and along the electrically conducting body, and iii) an outer layer formed on the outer periphery of the electrically conducting body, said outer layer being paper layer which is impregnated with a silicate material such as sodium silicate.
Referring now to the accompanying drawing:
Figure 1 is a front view partially broken away of an electrode for oxygen-arc cutting in accordance with this invention.
Figure 2 is a cross-sectional view of the electrode of Fig. 1 taken along line I-I.
C
1~78928 In the drawings, the electrode comprises an electrically-conducting body 3" made of iron or the like which has a longitudinal oxygen passage 1" formed within and along the conducting body 3" and a cylindrical outer layer 4"
which is made of paper in which silicate material in sufficient quantity is impregnated.
In this invention, silicate material may be chosen such that it easily impregnates the paper outer layer wherein, according to an experiment conducted by the inventor, an electrode with a paper outer layer which contains the impregnated silicate material, forming approximately 60% by weight of the paper made outer layer, shows most favourable results.
It should-also be noted that ferric oxide, which improves the oxygen-arc cutting operation may be mixed into the paper made outer layer.
In one method of forming the electrode, a paper cylinder or tube is first prepared and is impregnated with silicate material and subsequently a tubular conducting body 3"
is inserted into and fixedly adhered to the paper outer layer by a binder such as sodium silicate. In another method, paper ; which has already been impregnated with silicate material is coiled around the outer periphery of a tubular electrically-conducting body.
According to this invention, since the silicate impregnatedpaper outer layer 4" fixedly encloses the tubular conducting body 3", the outer layer protects the tubular conducting body 3" and enhances the generation of arc which results in an increase in arc heat.
Other advantages of the electrode of this invention are:
1) arc heat is stabilized C-.

Other advantages of the electrode of this invention are:
1) arc heat is stabilized C-.
2) the paper outer layer is prevented from peeling off.
3) the amount of gas of an offensive odour can be reduced to one-third of that produced by conventional elec-trodes, resulting in an easier cutting operation.
