For achieve the above object two, the present invention takes following steps:
1. make flammable core rod and flammable internal mold respectively, in flammable internal mold, insert flammable core rod, the flammable internal mold that inserts flammable core rod is installed in the punching block, the fastening bolt nut, interior external mold is fixed, and becomes compound die, and is stand-by;
2. the raw material with heat storage drops in the mixer dried mixing, stand-by by the accurate weighing of prescription requirement; Common honeycomb type heat storage raw material proportioning following (weight meter): aggregate 40-60 part; Matrix material 30-50 part; Bond 7-12 part; Water reducer 0.06-1.3 part.Above-mentioned aggregate adopts corundum in granules, alumine particle, mullite particle or cordierite particle, and above-mentioned matrix material adopts fused mullite powder, andalusite powder or electricity combustion zirconium mullite powder; Above-mentioned bond adopts pure calcium aluminate cement and high temperature alumina micro mist or silicon ash; Above-mentioned water reducer adopts sodium phosphate trimer or calgon.
3. will drop into through raw materials mixed and add the water wet mixing in the mixer, and form and water material feeding;
4. adopt while vibrating reinforced pouring type will water in the internal mold that material feeding adds compound die gradually, promptly shed the punching block of compound die after cast finishes, maintenance at least 1 day makes watering the material feeding moulding and become semi-finished product in the internal mold;
5. the related internal mold of semi-finished product being put into the high-temperature baking baking oven together toasts, the oven temperature is heated to 1400~1500C ° gradually from normal temperature, and warm-up time is 270~280 hours, in the process of heating, flammable internal mold and flammable core rod burning cool to normal temperature with the furnace and are the honeycomb type heat storage finished product.
The mixer of above-mentioned steps in 2. is conical twin-screw mixer, and mixer is a forced mixer.
The oven of above-mentioned steps in the 4. process of heating is as follows, heats to 150 ℃ from room temperature, and the time is 32 hours, 150 ℃ of insulations 32 hours down; Heat to 350 ℃ from 150 ℃, the time was 24 hours, 350 ℃ of insulations 68 hours; Heat to 600 ℃ from 350 ℃, the time was 24 hours, 600 ℃ of insulations 28 hours; Heat to 800 ℃ from 600 ℃, the time is 20 hours, 800 ℃ of insulations 12 hours down; Heat to 1450 ℃ from 800 ℃ at last, the time is 20 hours, is incubated 3 hours.
The present invention has following characteristics:
1, taking " mould in the mould " is compound die, and flammable internal mold is set in the punching block as external mold, can shed punching block after cast finishes, and punching block can enter the cast of next mould at once, and the punching block holding time is short, and turnover is fast, reduces investment, is convenient to enlarge produce.
2, owing to do not need artificial demoulding core, shorten process time, improved labor productivity and reduced the disqualification rate that causes accidentally because of demoulding core.
3, simplified technology, the convenient manufacturing.
4, because the punching block turnover is fast, process time is short, so production cost significantly reduces.
