Description
Technical field
The present invention's not copper facing gouge carbon-point is mainly used in the cutting of steel plate, the present invention be more particularly directed to the improvement of not copper facing gouge carbon-point and process thereof.
Background technology
The existing process preparing gouge carbon-point is, pitch coke 45%, graphous graphite powder 30%, pitch 35%, is weight ratio; By above-mentioned material kneading, carry out being squeezed into bar-shaped, extruding in 1/3 second, namely extrudes three each second, by the long 300 millimeters of calculating of every root; At the temperature of 1200 ~ 1300 DEG C, carry out roasting, shaping rear bar proportion is 1.42 ~ 1.5.This bar due to extrusion speed fast, density can be caused low, produce a lot of pore therefrom, be stored in after air enters in pore, product is very easily oxidized; Because bar is solid construction, rupture strength is poor.For addressing these problems, the means taked at present are, after above-mentioned technique completes, then are increased in the copper-plated operation of Surface of Rod Bar, become gouge carbon-point after copper facing, so just can improve oxidation resistance and the rupture strength of product, strengthen its conductance.Owing to adding copper-plating technique, therefore in production process and in the use procedure of product, severe contamination is caused to surrounding enviroment; Because this product is in steel plate cutting process, a large amount of harmful substances and harmful vapors can be produced, also injury be caused to human body simultaneously.
Because carbon-point is cylindrical structure, head and afterbody both ends of the surface are plane, and in use, head end contact area is large, can affect the speed that arcing temperature rises, weaken cutting power during cutting steel plate, and cut part quality is unstable; Tail end face easily hurts people.
Summary of the invention
The present invention is the shortcoming overcoming the existence of above-mentioned prior art, provides a kind of not copper facing gouge carbon-point and process thereof of improvement.
One not copper facing gouge carbon-point process, it is characterized in that, material by its weight ratio is, pitch coke 40 ~ 45%, graphous graphite powder 20 ~ 25%, antioxidant 5 ~ 6%, pitch 28 ~ 30%;
(1), after above-mentioned material being stirred kneading, the bar that extruder is squeezed into band centre bore is entered; Diameter of rod 8 ~ 18mm, center-hole diameter is 2 ~ 6mm; Extruding in 1/2 second one;
(2) enter in roaster, at the temperature of 1200 ~ 1300 DEG C, carry out roasting, the time is 7 ~ 8 days;
(3) by roaster power-off, roaster inside holding 6 ~ 7 days; Open roaster, Temperature fall 5 ~ 7 days; Bar proportion is 1.56 ~ 1.62.
Preferably, material by its weight ratio is, pitch coke 45%, graphous graphite powder 20%, antioxidant 5%, pitch 30%.
In addition, the invention also discloses a kind of not copper facing gouge carbon-point made according to above-mentioned not copper facing gouge carbon-point process.
Present invention process thoroughly solves the shortcoming that prior art exists because of top layer plating cathode copper, effectively avoids producing and pollution on the environment and the injury to human body in use procedure, protects environment; The present invention can effectively reduce to produce and produce this, and can enhance productivity.
Because the present invention's not copper facing gouge carbon-point is with centre bore, add rupture strength, product should not be out of shape under internal stress effect.The improvement of technique, extruding in 1/2 second one, namely extrudes two each second, compared with the prior art, under equal conditions, extrude the bar of identical length, extrusion speed slows down, and the density of bar will increase, pore will reduce, avoid the air stored in advance, carbon-point proportion increases, and therefore improves carbon-point antioxygenic property.The combination of multiple material of the present invention and the technique of improvement, make not copper facing gouge carbon-point enhance rupture strength, enhance conductance, extend the service life of product.Add antioxidant in the present invention's formula, also enhance antioxygenic property accordingly.
After above-mentioned technique, more shaping rear bar is carried out machined, head is cone shape, and tapering is 1:50, and the end face of afterbody is at 45 ° × 1.5 chamferings; Not copper facing gouge carbon-point is become after machined.
When the present invention's not copper facing gouge carbon-point uses, the high temperature that cutting produces can constantly upwards extend along the inclined-plane of head cone, and in continuous oxidizing process, the form trait of cone is roughly constant.Because not copper facing gouge carbon-point head adopts cone shape, cone front end face contact area is little, is the speed that can increase the rising of arcing temperature, increases cutting power, not only using electricity wisely, improve precision and the surface smoothness of work piece simultaneously in cutting.The end face of carbon-point afterbody is at 45 ° × 1.5 chamferings, during use, can not damage staff.
The present invention can be widely used in the industry such as shipbuilding, boiler, casting, to the reparation of big-and-middle-sized Steel structure equipment, steel plate channeling, the cuttings such as stainless steel, mild steel, cast iron and non-ferrous metal, front groove, stripping rib, punchings etc., have efficiency high, the features such as noise is little, alleviate labour intensity, output and product quality can be improved.
Accompanying drawing explanation

1 not copper facing gouge carbon-point, 2 centre bores, 3 cones, 4 chamferings.
Detailed description of the invention
One not copper facing gouge carbon-point process, material by its weight ratio is, pitch coke 45%, graphous graphite powder 20%, antioxidant 5%, pitch 30%;
(1), after above-mentioned material being stirred kneading, enter extruder and be squeezed into the bar-shaped of band centre bore 2; Diameter of rod 8mm, center-hole diameter is 2mm; Extruding in 1/2 second one; Long 300 millimeters of every root;
(2) enter in roaster, at the temperature of 1200 ~ 1300 DEG C, carry out roasting, the time is 7 ~ 8 days;
(3) by roaster power-off, roaster inside holding 6 ~ 7 days; Open roaster, Temperature fall 5 ~ 7 days; Bar proportion is 1.56 ~ 1.62;
(4) shaping rear bar is carried out machined, head is cone 3, and tapering is 1:50, and the end face of afterbody is at 45 ° × 1.5 chamferings 4; Become not copper facing gouge carbon-point 1 after machined, carbon-point diameter accuracy ± 0.05mm, carbon-point surface smoothness is minute surface.
Why carbon-point diameter accuracy is ± 0.05mm, and when being because of work, the change of carbon-point sectional area size can cause the change of resistivity, thus affects the quality of work piece; Carbon-point surface smoothness is minute surface, and can weaken carbon-point anti-oxidant, work quality is stablized, and can ensure precision and the surface smoothness of work piece; The service life of carbon-point can be extended simultaneously.
