Abstract
The invention relates to a vermicular cast iron calcium carbide pot and a manufacture method thereof. The calcium carbide pot comprises a pot body and a pot bottom, wherein the pot body and the pot bottom are respectively manufactured by a casting method, the pot bottom is placed inside the pot body, and the upper end of the pot body is provided with a shielding edge. The invention adopts vermicular cast iron with the advantages of good material heat conductivity, low elasticity modulus and high high-temperature intensity for manufacturing the calcium carbide pot, and in addition, heat treatment is carried out after the casting work procedure is completed, so the calcium carbide pot can resist sharp quenching and sharp heating in use, and chances of crack and deformation of the pot body of the calcium carbide pot are reduced. Thereby, the service life of the calcium carbide pot is prolonged.
Description
Technical field
The present invention relates to a kind of vermicular cast iron calcium carbide pot and manufacture method thereof.
Background technology
Calcium carbide pot is the come out of the stove container of calcium carbide of splendid attire, when fused high-temperature liquid state calcium carbide is emitted in by stove, is responsible for shipment by a string tens of mouthfuls of calcium carbide pots that are arranged in before the furnace of calcium carbide.Calcium carbide pot is whenever filled pot flatly by vehicle-mounted, and car is just walked once forward, and distance is the length of a pot position just.Adorn one like this and walk one, the calcium carbide of earlier pre-installed pot condenses into stone roller one by one after the some time.Draw off the calcium carbide stone roller, empty pot is luggage fortune again, recycles.
Existing calcium carbide pot adopts the regular gray iron casting to form, also useful cast steel calcium carbide pot.Because calcium carbide pot is to be heated repeatedly, to work under the refrigerative mal-condition, so the characteristic of its material directly influences its work-ing life.Under the effect of thermal stresses, the pot of plain cast iron material may rupture, and the pot of cast steel then tension set can take place.
Summary of the invention
The objective of the invention is to overcome the defective of above-mentioned prior art, a kind of prevent a pot body cracking, distortion are provided, prolong the calcium carbide pot vermicular cast iron calcium carbide pot in work-ing life.
A kind of vermicular cast iron calcium carbide pot comprises pot body and the bottom of a pan, it is characterized in that: the described pot body and the bottom of a pan adopt castmethod to make respectively, and the bottom of a pan is placed on the inside of pot body, and pot body upper end is provided with cover edge;
The vermicular cast iron manufacturing is all adopted in the described pot body and the bottom of a pan;
Above-mentioned castmethod is:
A. make the polystyrene model according to pot body or form of pot bottom,
B. at model surface brush refractory paint, dry,
C. model and gating system are put in the sandbox simultaneously, inserted dry sand, jolt ramming covers the sandbox top with plastics film,
C. with vacuum pipe with the air emptying in the sandbox;
D. introduce acetylene and oxygen burning-off polystyrene model, stay the die cavity that the refractory paint ghost forms,
E. inject vermicular cast iron water by gating system, vermicular cast iron water occupies die cavity, solidify the back the pot body or the bottom of a pan;
The pot body and the bottom of a pan that above-mentioned casting is good reheat to annealing more than the critical temperature, in the hope of reaching the purpose that eliminates stress.
The present invention's employing has the China ink of wriggling that the material thermal conductivity is good, Young's modulus is low, hot strength is high and makes calcium carbide pot, and after casting process is finished, heat-treat, make the in use anti-rapid heat cycle of calcium carbide pot, reduced the chance of calcium carbide pot pot body cracking and distortion, thus the work-ing life of having improved calcium carbide pot.

Fig. 3 is the manufacture method synoptic diagram of vermicular cast iron calcium carbide pot of the present invention.
Embodiment
Vermicular cast iron calcium carbide pot of the present invention comprises pot body 3 and the bottom of a pan 4, and pot body 3 and the bottom of a pan 4 splits design can conveniently draw off the calcium carbide camel like this, also are convenient to change the bottom of a pan of rapid wear.The pot body 3 and the bottom of a pan 4 all adopt castmethod to make, and are material with the vermicular cast iron.Be provided with cover edge 5 in pot body 3 upper ends, purpose is for the hole between two pots of the shields, the bottom of a pan 4 rectangular plates.After casting was finished, the bottom of a pan 4 is laid in formed calcium carbide pot 1 on pot body 3.Calcium carbide pot 1 is placed on a string dolly that interlinks 2 in use.
During casting, pouring into a mould after pot body 3 and the bottom of a pan 4 cased respectively, is the concrete castmethod of example statement with the pot body below again:
A. according to pot shape modeling 9, model 9 adopts the polystyrene material manufacturing, and polystyrene material both had been our usually said disappearance mould;
B. with model 9 external coating refractory paints, form duricrust after the oven dry;
C. model 9 and gating system 12,6 are put into sandbox 11 simultaneously, insert dry sand 8, jolt ramming covers sandbox 11 tops with plastics film 7;
D. start vacuum pump by vacuum pipe 10 with the air emptying in the sandbox 11, make dry sand 8 have certain degree of hardness;
E. introduce acetylene and oxygen burning-off polystyrene model 9, stay the die cavity that the refractory paint ghost forms;
F. inject vermicular cast iron water by gating system 12,6, vermicular cast iron water occupies die cavity, promptly is required pot body after solidifying.
The pot body and the bottom of a pan that above-mentioned casting is good reheat to annealing more than the critical temperature, in the hope of reaching the purpose that eliminates stress.
