B, the graphite waste material is carried out cleaning, the graphite waste material that will carry out after the cleaning is tailored into suitable graphite scrap;
C, the usefulness instrument of weighing are weighed to the graphite block after tailoring, and its quality is pressed M=ρ ∏ (D
2-d
2) H/4 calculating, make it satisfy the requirement of density among the JB/T6370-92;
Wherein: ρ: the density of product during temperature t ℃, unit is g/cm
3
M: the quality of product, unit is g;
D: the external diameter of product, unit are cm;
D: the internal diameter of product, unit are cm;
H: the average height of product, unit is cm;
D, the graphite scrap after will weighing add hydraulic press;
E, adjust hydraulic press pressure to 0.3 to 0.4mpa, keep 10 to 20s, in 10s, at the uniform velocity be loaded on 30mpa to 40mpa, unload after keeping 55-65s, form carbon packing ring;
F, fineness is carried out on the surface of the carbon packing ring that forms among the step D process, with the coefficient of reducing friction, strengthen sensory effects.
Preferably, the pressure of forcing press is adjusted to 0.35mpa among the described step D, keep 15s after, in 10s, at the uniform velocity be loaded on 35mpa, unload after keeping 60s, form carbon packing ring.
Preferably, the instrument of weighing that uses among the described step C is the balance of sensibility reciprocal as 0.001g.
Beneficial effect of the present invention is: one, the present invention utilize waste and old graphite to make carbon packing ring by hydraulic press, tailing and residue after the monoblock graphite cake processing can be chipped (20-30% that is approximately whole graphite cake) etc. collect, make carbon packing ring by preparation method of the present invention again, waste material is carried out recycling, reduce enterprise's production cost, improve stock utilization, meet the theory of energy-conserving and environment-protective; Two, product quality has obtained corresponding raising, because waste and old graphite has re-started combination processing after pulverizing, make the density of packing ring more evenly moderate, thereby obtained more suitable compression ratio, and can arbitrarily adjust, made it satisfy actual requirement, rebound degree is greatly improved, adopt simultaneously supporting with it process for treating surface, made the coefficient of friction obtain corresponding reduction, reached better sealing effectiveness.
[specific embodiment]
The invention will be further described below in conjunction with embodiment.
What the present invention disclosed is a kind of preparation method of waste and old graphite karbate impervious graphite packing ring, by this preparation method, carbon packing ring can be recycled and made to waste and old graphite; It may further comprise the steps:
The mould that A, selection and product are supporting and hydraulic press, the tolerance of its mould should meet the requirement of GB/T1804, and the tolerance of the carbon packing ring after the assurance moulding meets GB/T1804.
B, the graphite waste material is carried out cleaning, such as removing impurity, dust etc., the graphite waste material that will carry out after the cleaning is tailored into suitable graphite scrap, is convenient to add hydraulic press get final product;
C, the usefulness instrument of weighing are weighed to the graphite block after tailoring, and its quality is pressed M=ρ ∏ (D
2-d
2) H/4 calculating, make it satisfy the requirement of density among the JB/T6370-92;
Wherein: ρ: the density of product during temperature t ℃, unit is g/cm
3
M: the quality of product, unit is g;
D: the external diameter of product, unit are cm;
