Abstract
A method for making molten-rock castings with basalt as raw material includes such technological steps as melting basalt at 1280-1320 deg. C, moulding, demoulding, and annealing in kiln from 800deg. C to 480-520 deg. C through 11-16 hr, and further lowering temp. to normal through 9-14 hr, and features high rate of finished products increased to 90% or more, short production period decreased by 130 hr, and saving energy by 37%.
Description
The present invention relates to a kind of method of making the cast stone product, particularly is the method for raw material to produce cast stone tubing, sheet material and other product with basalt.
Making the cast stone product at present both at home and abroad, is raw material with basalt or diabase mainly, each manufacturer of selection of raw material is mainly considered the resource of locality.Known technology generally adopts following operation to make the cast stone product: (one) fusing---raw material is melted in smelting furnace, the cast stone melt is melted to about 1400 ℃, the melt of (two) moulding---fusing is in die for molding, the demoulding, (3) annealing---section bar after the moulding was in the annealing kiln annealing, and the kiln temperature was reduced to normal temperature by 800 ℃ through 168 hours.Because temperature of fusion is too high, a large amount of magnetite molecular combinations are damaged, make cast stone rock melt be not easy crystallization, the easy modification of section bar after the demoulding, annealing time is oversize, the finished product rate can only guarantee about 70%, and wastes energy, and selected reasonable technological parameter is that the cast stone industry is badly in need of the technical barrier that solves.
The object of the present invention is to provide a kind of is the method for raw material to produce cast stone product with basalt, makes the selected comparatively reasonable of its processing parameter, to overcome the deficiency of above-mentioned manufacture method.
The present invention is achieved in that a kind of is the method for raw material to produce cast stone product with basalt, it is finished by following operation: (one) dissolves---in smelting furnace, basalt is fused into melt, (2) moulding---melt is the demoulding after die for molding, (3) annealing---the section bar after the demoulding is eliminated internal stress in the annealing kiln annealing, its improvements are that melt is melted to 1280 ℃～1320 ℃ in melting process, the temperature of annealing furnace was reduced to 480 ℃～520 ℃ by 800 ℃ through 11～16 hours in annealing operation, reduced to normal temperature again through 9～14 hours.
Manufacture method of the present invention can be that melt is melted to 1300 ℃ in melting process.
Manufacture method of the present invention can be that the temperature of annealing furnace in annealing operation was reduced to 500 ℃ by 800 ℃ through 12 hours, reduced to normal temperature again through 10 hours.
The cast stone finished product rate of manufacture method manufacturing of the present invention is brought up to more than 90%, and the production cycle has shortened 130 hours, saves the energy 37%.
The present invention will be further described in conjunction with the embodiments.
Embodiment 1, (1) dissolve---be that raw material melts in smelting furnace with basalt, melt is melted to 1300 ℃, (2) moulding---melt is the demoulding after die for molding, (3) annealing---the section bar after the demoulding is in the annealing kiln annealing, disappear and get internal stress, the kiln temperature was reduced to 500 ℃ by 800 ℃ through 12 hours and was reduced to normal temperature again in 10 hours.The tubing yield rate of present embodiment manufacturing is 93%, and the sheet material yield rate is 94%.
Embodiment 2, and in melting process, melt is melted to 1320 ℃, and other processing parameter is identical with embodiment 1, and the tubing yield rate of manufacturing is 91%, and the sheet material yield rate is 93%.Research and analyse and think, when melt reached 1320 ℃, molten intravital segment magnet ore deposit molecular combination was damaged, and influences the crystallization of melt, makes the decrease in yield of product.
Embodiment 3, melt is melted to 1280 ℃ in melting process, other processing parameter is identical with embodiment 1, the tubing yield rate of making is 90%, and the sheet material yield rate is 92%, researchs and analyses and thinks, when melt temperature of fusion≤1280 ℃, melt contains the peridotites particle, has destroyed the homogeneity of melt, makes decrease in yield.
By above-mentioned 3 embodiment as can be seen, more reasonable when melt is melted to 1300 ℃ in melting process.
Embodiment 4, and in melting process, melt is melted to 1300 ℃, and the annealing furnace temperature was reduced to 480 ℃ by 800 ℃ through 12 hours in annealing operation, reduced to normal temperature again through 10 hours, and the tubing yield rate of manufacturing is 92%, and the sheet material yield rate is 93%.
Embodiment 5, and melt is melted to 1300 ℃ in melting process, and the annealing furnace temperature was reduced to 520 ℃ by 800 ℃ through 12 hours the time in annealing operation, reduced to normal temperature again through 10 hours; The tubing yield rate of making is 92%, and the sheet material yield rate is 93%.
Embodiment 6, and in melting process, melt is melted to 1300 ℃, and in annealing operation, the annealing furnace temperature was reduced to 500 ℃ by 800 ℃ through 10 hours, reduced to normal temperature again through 10 hours.The tubing yield rate of making is 90%, and the sheet material yield rate is 91%.
Embodiment 7, and melt dissolves to 1300 ℃ in melting process, and in annealing operation, the temperature of annealing furnace was reduced to 500 ℃ by 800 ℃ through 16 hours, reduced to normal temperature again through 10 hours, and the tubing yield rate of manufacturing is 93%, and the sheet material yield rate is 94%.
Embodiment 8, and in melting process, melt is melted to 1300 ℃.In annealing operation, the temperature of annealing furnace was reduced to 500 ℃ by 800 ℃ through 12 hours and was reduced to normal temperature again through 9 hours, and the tubing yield rate of manufacturing is 91%, and the sheet material yield rate is 92%.
Embodiment 9, and in melting process, melt is melted to 1300 ℃.In annealing operation, the temperature of annealing furnace was reduced to 500 ℃ by 800 ℃ through 12 hours and was reduced to normal temperature again through 14 hours, and the tubing yield rate of manufacturing is 93%, and the yield rate of sheet material is 94%.
Comprehensive above-mentioned 9 embodiment, as can be seen, the effect that the processing parameter of embodiment 1 is selected is best.
